You should write at least 150 words but no more than 200 words.Online Learning: Advantages and DisadvantagesOnline learning, also known as e-learning or distance education, has gained increasing popularity in recent years. It provides students with the flexibility to study at their own pace and convenience. However, it also brings some disadvantages.One of the advantages of online learning is the flexibility it offers. Students can access course materials and lectures anytime and anywhere as long as they have an internet connection. This is especially beneficial for working adults who may not have the time to attend traditional classes. Moreover, online learning allows students to review the materials repeatedly until they fully understand the concepts.Another advantage is the cost-saving aspect. Online courses are often more affordable than traditional classroom-based courses. Students can save money on commuting, housing, and textbooks. Additionally, online learning opens up opportunities for students who do not have access to certain courses or universities in their local area.Despite its advantages, online learning also has some disadvantages. The lack of face-to-face interaction with instructors and peers can be a drawback for some students. Students may feel isolated and miss out on social interactions that are often experienced in a traditional classroom setting. Moreover, self-discipline and time management skills are crucial for successful online learning, and not all students possess these qualities.In conclusion, online learning has both advantages and disadvantages. It provides flexibility and cost-saving benefits, but it may also result in a lack of social interaction and require strong self-discipline from students. As technology continues to advance, it is important to find a balance between online and traditional learning methods for optimal educational experiences.答案及解析听力：1-3 主旨题。

大学英语四级考试模拟试卷(附答案)

大学英语四级考试模拟试卷Part ⅠWritingDirections:For this part, you are allowed 30 minutes to write a letter of advice to your cousin about how to spend the first winter holiday in college. You should write at least 120 words following the outline given below.1、现在网上购物已成为一种时尚2．网上购物有很多好处，但也有不少问题3．我的建议Part ⅡReading Comprehension (Skimming and Scanning)Exchange Rates：A Brief History of Exchange RatesFor centuries，the currencies of the world were backed by gold．That is，a piece of paper currency issued by any world government represented a real amount of gold held in a vault by that government．In the 1930s，the U.S.set the value of the dollar at 8 single，unchanging level：l ounce of gold was worth $35．After World War II，other countries based the value of their currencies on the U.S.dollar．Since everyone knew how much gold a U.S.dollar was worth，then the value of any other currency against the dollar could be based on its value in gold．A currency worth twice as much gold as a U.S.dollar was，therefore，also worth two U.S.dollars．Unfortunately，the real world of economics outpaced this system．The U.S.dollar suffered from inflation(its value relative to the goods it could purchase decreased)，while other currencies became more valuable and more stable．Finally，in 1971，the U.S.took away the gold standard altogether．This meant that the dollar no longer represented an actual amount of a precious substance-market forces alone determined its value．Today，the U.S.dollar still dominates many financial markets．In fact，exchange rates are often expressed in terms of U.S.dollars．Currently，the U.S.dollar and the euro account for approximately 50 percent of all currency exchange transactions in the world．Adding British pounds，Canadian dollars，Australian dollars，and Japanese yen to the list accounts for over 80 percent of currency exchanges altogether．Methods of Exchange：the Floating Exchange RateThere are two main systems used to determine a currency's exchange rate：floating currency and pegged currency．The market determines a floating exchange rate．In other words，a currency is worth whatever buyers are willing to pay for it．This is determined by supply and demand，which is in turn driven by foreign investment，import/export ratios，inflation，and a host of other economic factors．Generally，countries with mature，stable economic markets will use a floating system．Virtually every major nation uses this system，including the U.S.，Canada and Great Britain．Floating exchange rates are considered more efficient，because the market will automatically correct the rate to reflect inflation and other economic forces．The floating system isn't perfect，though．If a country's economy suffers from instability，a floating system will discourage investment．Investors could fall victim to wild swings in the exchange rates，as well as disastrous inflation．Methods of Exchange：the Pegged Exchange RateA pegged，or fixed system，is one in which the exchange rate is set and artificially maintained by the government．The rate will be pegged to some other country's dollar，usually the U.S.dollar．The rate will not fluctuate from day to day．A government has to work to keep their pegged rate stable．Their national bank must hold large reserves of foreign currency to mitigate changes in supply and demand．If a sudden demand for a currency was to drive up the exchange rate，the national bank would have to release enough of that currency into the market to meet the demand．They can also buy up currency if low demand is lowering exchange rates．Countries that have immature，potentially unstable economies usually use a pegged system．Developing nations can use this system to prevent out-of-control inflation．The system can backfire，however，if the real world market value of the currency is not reflected by the pegged rate．In that case，a black market may spring up，where the currency will be traded at its market value，disregarding the government's peg．When people realize that their currency isn’t worth as much as the pegged rate indicates，they may rush to exchange their money for other，more stable currencies．This can lead to economic disaster，since the sudden flood of currency in world markets drives the exchange rate very low．So if a country doesn't take good care of their pegged rate，they may find themselves with worthless currency．Methods of Exchange：HybridsIn reality，few exchange rate systems are 100 percent floating，or 100 percent pegged.Countries using a pegged rate can avoid market panics and inflationary disasters by using a floating peg．They peg their rate to the U.S.dollar，and that rate doesn't fluctuate from day to day．However，the government periodically reviews their peg，and makes minor adjustments to keep it in line with the true market value。

People are increasingly choosing to have multiple careers throughout their lives. There are several reasons for this trend.First, the job market is constantly changing. New industries are emerging, and old ones are disappearing. This means that people may need to retrain and change their careers in order to stay employed. For example,with the rise of the digital age, many people who used to work intraditional print media have had to learn new skills in order to work in online media.Second, people are living longer and healthier lives. This gives them more time to pursue different interests and careers. They may want to try something new after spending many years in one field. For example, a person who has worked as a doctor for 20 years may decide to study art and become an artist in their later years.Finally, having multiple careers can be more fulfilling. It allows people to explore different aspects of their personalities and talents.They can gain different experiences and skills from each career, which can make them more well - rounded individuals.41. What is the old - fashioned concept mentioned in the passage?42. Why do people need to change their careers according to the passage?43. What is an example of the job market change given in the passage?44. How does living longer affect people's career choices?45. What are the benefits of having multiple careers?Passage 2.Questions 46 - 50 are based on the following passage.In recent years, the sharing economy has become a popular trend. The sharing economy refers to the economic model in which people share resources, such as cars, houses, and tools, through online platforms. There are several advantages of the sharing economy.First, it can save resources. For example, if people share cars, fewer cars will be needed, which can reduce the consumption of energy and raw materials. Second, it can be more cost - effective. For example, people can rent a house or a car at a lower price through sharing platforms than they would if they were to buy or rent them in the traditional way. Third, itcan also promote social interaction. When people share resources, they have the opportunity to meet and interact with other people.However, the sharing economy also has some challenges. One of the main challenges is the lack of regulation. Since the sharing economy is a relatively new concept, there are not enough laws and regulations to govern it. This can lead to problems such as safety concerns and unfair competition. Another challenge is the issue of trust. People need to trust the people they are sharing resources with and the platforms they are using.46. What is the sharing economy?47. What are the advantages of the sharing economy?48. What is the main challenge related to the lack of regulation in the sharing economy?49. Why is trust an issue in the sharing economy?50. Do you think the sharing economy will continue to grow in the future? Why or why not?Section C.Directions: There is one passage in this section. You are required to answer the questions below the passage according to what is stated or implied in the passage.Passage.The concept of "green living" has been around for a while, but it has become more important in recent years. Green living refers to a lifestyle that is environmentally friendly and sustainable. There are many ways to practice green living.One way is to reduce waste. We can do this by recycling, reusing, and reducing our consumption. For example, we can recycle paper, plastic, and glass products. We can also reuse items such as shopping bags and water bottles. And we can reduce our consumption of non - renewable resources such as oil and coal.Another way is to use renewable energy sources. We can install solar panels on our roofs to generate electricity. We can also use wind turbines in areas with strong winds. These renewable energy sources are clean and sustainable, and they can help reduce our dependence on fossil fuels.In addition, we can also choose environmentally friendly products. For example, we can choose products made from recycled materials or products that are biodegradable. We can also choose products that are produced in an environmentally friendly way, such as products that are made without using harmful chemicals.51. What is "green living"?52. How can we reduce waste?53. What are some renewable energy sources mentioned in the passage?54. What are the characteristics of renewable energy sources?55. How can we choose environmentally friendly products?四、翻译（15%）Part A.Directions: Translate the following sentences into English.1. 他是一个勤奋的学生，总是第一个到教室。

These cars are available in the US today from 2 or 3 manufacturers and many more are on the way.What Are Hybrid Cars?A vehicle is a hybrid if it has more than one source of power. We have hybrid vehicles all around us such as diesel-electric trains, diesel-electric buses, and nuclear-electric submarines. Maybe some of you remember the Mo-Ped, a modified bicycle that used a combination of a gasoline engine and muscle power of its rider. In a similar manner, the gasoline-electric hybrid car is a combination of gasoline-powered car and an electric car.What Is Reason for Developing Such a Complicated Car?There are two major reasons: 1) To reduce tailpipe emissions and 2) To increase average gas mileage. These two goals interact with each other so that the overall performance of the hybrid car enhances both of them, today’s hybrids provide gas efficiency of 40 to 60 miles/gallon. The hybrids have reduced emissions to approximately 10% of the Japanese standards or about equal to the California standards, which are the most restrictive in the US.How Do Hybrid Car Work?There are two types of hybrid cars. One is known as the parallel hybrid and the other is known as a series hybrid. Both types use the same components, which are:●Small Gasoline Engine●Fuel Tank●Electric Motor●Generator (used mostly in the series hybrid)●Batteries●Transmission●In the parallel hybrid, the fuel tank supplies gasoline to engine and batteries supplypower to the electrical motor. Both the engine and the electric motor can turn the transmission at the same time, and the transmission turns the wheels. An onboard computer controls the system so that the maximum efficiency is obtained. In a series hybrid, the gasoline engine turns a generator, which either charges the batteries or powers an electric motor that drives the transmission. The gasoline engine never powers the vehicle directly.How Do These Combinations Meet the Desired Goals?The key to hybrid car performance is that the gasoline engine can be much smaller than the engine in a conventional high horsepower car. But how can this be when you will be competing on the highway with much more powerful autos on the road?The answer is that a conventional engine must supply power for all driving conditions. The engine needs to be powerful enough to accelerate onto a freeway and up hills, but it to use only a small percentage of its power at highway speeds.In a hybrid, the gasoline engine provides the power at higher highway speeds and the battery-electric motor combination provides the power for city driving and for acceleration needs. With this combination, each power source works at its optimal level.Some other tricks the hybrid car uses to get more efficiency are as follows:The system returns energy to the battery when it decelerates. When you push on the brakes, the electric motor acts as a generator and recharges the battery. This energy is lost in a conventional car.The hybrid can shut off the gasoline motor when it is not needed. This is very important when you are doing stop and go driving in the city and you have to stop a lot (gasoline is not wasted by running the engine at idle while the car waits at a traffic light.)Hybrid cars are designed with the latest aerodynamics. This reduces the drag at higher highway speeds.Hybrid use low-rolling resistant tires. These are stiffer and inflated to a higher pressure and cause about half the drag of conventional tires. The ride is a little rougher but the gas saving can be huge.Hybrid also use very lightweight materials. This reduces the overall weight of the car and the mileage is increased.The above designs will provide a very useful and comfortable auto that also gives you a maximum of gas mileage.Hybrids are somewhat scarce right now (about 3% of the cars sold in the US) but should be plentiful for next year’s models (2005).The above description of hybrid cars is meant to be only an introduction to this new technology. If you are interested in getting one of these marvelous cars in the future, you should start your investigation now. Take a test drive in some of the available hybrid cars, you will find some surprises. One is that the cars are extremely quiet, they have additional insulation in order to decrease the need for air conditioning and heating (the purpose is to save energy but the resulting quietness is a very nice benefit). A second is that these cars are very peppy, unlike early automobiles designed for energy conservation. The advantages and disadvantages will vary with each manufacturer, type and model of the hybrid. It will take a lot of time to look at all the various models but it will be well worth it for your future driving pleasure.(N) There is enough fossil fuel in the world, but it will be difficult to find and to extract it from the ground.(Y) In the US today, a lot of manufacturers are trying to produce hybrid cars in order to reduce these energy needs and to decrease pollution.(Y) Mo-Ped is one kind of hybrid vehicle.(NG) There are other types of hybrid which use different components.(N) In both types, the gasoline engine can work to drive the transmission.(NG) The most important advantage of hybrid car is that its gasoline engine can be much smaller than the engine in a conventional high horsepower car.(Y) The gasoline engine and the battery-electric motor in a hybrid work together to provide the power for city driving and for acceleration needs.Hybrid also use light materials to reduce _________ of the car. (the overall weight)The above designs can make a very useful and comfortable car which can also give you _________. (a maximum of gas mileage)If you want to get one hybrid car in the future, you should _________. (start your investigation now)Par t ⅣReading Comprehension (Reading in Depth) (25 minutes) Section AThe impact of the frontier has been traditionally assumed by historians, who have studied its 1(H) on mountain men and cowboys, on different political and social institutions. Yet the impact of the frontier on the most common dimension of life upon the family remains largely2(C) . Although family has been 3(L) significant in the historical process, it is relatively a new area of historical research.In terms of westward migration, family played a special role. For people who 4(I) the church as much as the state, family was the only institution that could be entrusted with the enterprise of settling the continent . A Christian family was enough of the church; a Christain family was 5(E) expression of political and social order. In 1862, Congress provided for the 6(O) of lands to heads of households in a law, but that law merely recognizes that settlement had been the business of families since the seventeenth century.Families took up the challenge of the western lands in a variety of ways. Some families moved west in loosely 7(G) groups made up of families in similar directions. They drew up constitutions and elected leaders and generally applied the democratic process to the journey west. The government, for its part, 8(A) little help—no maps or transportation, no tools or agricultural information, no medical services and little protection. Beyond the westward-running rivers there was no road until wagons left deep 9(D) on the ground so that one could see a trail—or until enough wagons became lost and doubled back to warn others against their mistakes. Nonetheless, the attraction of “free land” was irresistible. One day or another, in a wagon train orSection BPassage OneIn the past, it was believed that depression was more prevalent among the poorer and less educated people, but that is not the case. The truth is, depression can afflict people from all walks of life, and often it hits the most ambitious, creative and conscientious. It is fallacious to think that people on the corporate rung of the social ladder are not prone (易于) to this malady (疾病). In fact, executives and professionals who are burdened with mounting pressures in their work may succumb to all these pressures and become depressed. The suicide of Vincent Foster, Jr., a noted American lawyer and White House official is a case in point. Despite the glamour of his position, which many people thought enviable, the felt overburdened with pressures and decided to take the easy way out.Studies show that people born later in this century have experienced much more depression than those born earlier. In fact the rate of depression over the last two generations has increased tenfold. Experts theorize that it could be due to the fact that the younger generations have higher expectations from life and are therefore more likely to suffer from failure, disappointment and hence, depression.Depression is easily recognizable. The depressed person feels sad or down in the dumps, and loses interest in even the most pleasurable activities. Moreover, he suffers from either significant gain or loss of weight, sleeplessness or oversleeping, sluggish movement and thinking, fatigue,feelings of guilt and worthlessness, impaired concentration and forgetfulness, and in extreme cases, the afflicted person may have suicidal tendencies. It is often believed that depression runs in the family, but this is not conclusively so, since there are cases where depressed persons do not have a history of depression in their families. Depression is often work-related although at times it has its roots in family relations.People who suffer from depression need not stay in the closet, since it is not a sin or a shame to be depressed. A prompt visit to a psychologist means prompt treatment and hence prompt recovery. Experts guarantee that depression is easily treatable, and in nip-in-the-bud cases, the patient fully recovers in a few days, thanks to the variety of effective treatment available.(C)According to the author, depression _______ .A)affects the poor and less educated people more than the rich and successful onesB)seldom attacks executivesC)is not limited to any particular class of peopleD)is caused by one’s ambition(A)Studies shoe depression ________.A)is more common today than in the past decadesB)was more common in the old generationsC)increased ten times in the days of our parents and grandparentsD)afflicts only young people(D)Which of the following statements is NOT true?A)Very high expectations for the individual make him more prone to depression.B) A depressed person feels sad and dejected.C)People need not attempt to hide their depression because it’s not a shameful thing.D)Depression is hereditary.(B)Depression can be easily cured ________.A)if the patient is youngB)at the early stage of the diseaseC)when plants are in budD)if the patient goes to see a psychologist(B)The passage is mainly a ________.A)description of the symptoms of depressionB)brief introduction of depressionC)summary of the causes of depressionD)list of treatment of depressionPassage TwoTeachers always plan down to the minute what their students will be doing. This is good for kids, because it teaches them to stay on task and follow a schedule. But most homes aren’t run this way. If parents do plan their children’s lives minute by minute, what happens when that child grows up and goes to college? At some point, kids need to learn to manage their own time. This can be one of the valuable skills you help your kids develop outside of school. But it generally won’t happen all by itself, because there’s a big transition that happens when kids leave the structured school environment and come home.If you have kid stay alone at home, think hard about trying to find an adult who can be there and provide the support your child needs. If a supportive adult isn’t available, an expert namedMartin recommends you find an after-school program led by experienced professionals who will engage them in creative activities, nourish them with healthy snacks, and assist them with their schoolwork. If you are at home on the contrary, to take some break after the guys get started on diversions, because it’s hard to stop and do something like homework. “If that little bit of downtime is television, good luc k…getting them to do their homework.” says a professor of child development at California State University, “TV is addictive.”A better way to help your child unwind is with a healthy snack. “Wait until dinner, make a plate full of energizing food. You could even dish up part of the dinner you’re preparing a little early for the kids,” she says.While you’re sharing a snack, you can make a list of what your kids will get to do during their study breaks. The types of breaks recommended include shooting baskets, getting a drink, using the bathroom, or even playing a quick card game with parents. Your kids can be the ones to decide which breaks they’d like to take. But, as Freimuth says, your children will have to be honest about what kind of break will energize them and not upset their momentum.(A)The main purpose of this passage is _______.A)to provide some advice for the parents about children’s educationB)to explain how to prepare a pretty snack for your childrenC)to explain why the parents spoil their childrenD)to describe children’s lives after school(B)The words “this way”in the sentence “But most homes aren’t run this way”in the first paragraph most possibly means _______.A)to stay on the taskB)to arrange everything in detailsC)to give some lessons to childrenD)to behave in the structured school(C)According to the passage, the expert named Martin most probably takes up the following jobs EXCEPT _______.A) a specialist in children educationB) a professional consultant in a after-school programC)the leader of a research group about sports, such as basketballD)mostly the same as what Freimuth does(D)According to the last two paragraphs, the appropriate snacks that the parents provide will _______.A)upset the children’s momentumB)exhaust them by lots of dirty dishesC)make the children get addicted to TVD)bring more energy to children(C)Which of the following is NOT recommended for the break during the children’s study after class?A)Shoot baskets.B)Play some games with parents.C)Go out to drink some beverage in a bar for a long time.D)Relax a bit by using the bathroom.Part ⅤCloze (15 minutes)Most parents, I suppose, have had the experience of reading a bedtime story to their children. And they must have 1 how difficult it is to write a 2 children’s book.Either the author has aimed too 3 , so that the children can’t follow what is in his (or more often, her) the story, 4 the story seems to be talking to the readers.The best children’s books are 5 very difficult nor very simple, and satisfy both the6 who hears the story and the adult who7 it. Unfortunately, there are in fact 8books like this, 9 the problem of finding the right bedtime story is not 10 to solve.This may be why many of books regarded as 11 of children’s literature were in fact written for 12 . “Alice’s Adventure in Wonderland” is perhaps the most 13 of this.Children, left for themselves, often 14 the worst possible interest in literature. Just leave a child in bookshop or 15 and he will 16 willingly choose the books written in an imaginative way, or have a look at most children’s comics, full of the stories and jokes which are the 17 of teachers and right-thinking parents.Perhaps we parents should stop trying to brainwash children into 18 our taste in literature. After all children and adults are so 19 that we parents should not expect that they will enjoy the 20 books. So I suppose we’ll just have to compromise over thatPart ⅥTranslation (5 minutes) Children in this country, especially those in the rural areas, should be encouraged to _____________________________________ (利用一切教育机会). (take advantage of all educational opportunities)Much as he loves, _______________________ (他有时的确烦她). (he sometimes does getannoyed at her)While you are driving on the highway, you should remember to ____________________ (保持车距). (keep car distance)To impress his girl friend, ____________________________ (他不嫌麻烦) to bring her a doll he had ordered in Hong Kong.

For questions 8-10, complete the sentences with the information given in the passage.Main Energies for the BodyA balanced diet is one that provides an adequate intake of energy and nutrients for maintenance of the body and therefore good health. A diet can easily be adequate for normal bodily functioning, yet may not be a balanced diet.CarbohydratesCarbohydrates are a rapid source of energy, they are the body's fuel. The bulk of a balanced diet should be made from carbohydrates. If eaten in an excess of the dietary requirements carbohydrates are easily stored as fats in the cells, although carbohydrate is the first source of energy in the body. An average adult requires about 12,000kJ of energy a day, most of this is supplied by the respiration of carbohydrates in the cells.Carbohydrates are used principally as a respiratory substrates, i.e. to be oxidized to release energy for active transport, macromolecule synthesis, cell division and muscle contraction. Carbohydrates are digested in the duodenum and ileum and absorbed as glucose into cells. Sources of carbohydrates such as starch are rice, potatoes, wheat and other cereals. Sugars are also carbohydrates, sources of sugars are refined sugar - sucrose, which is a food sweetener and preservative and fruit sugars - fructose. If the diet lacks carbohydrate stores of fat are mobilized and used as an energy source.ProteinsProtein is not a direct source of energy in the body, it is used primarily for growth and repair of body tissues while remaining an energy source as a last resort. Proteins fulfill a wide variety of roles in the body. They are broken down in the stomach and intestines to amino acids which are then absorbed. The body can only form 8 amino acids to build proteins from, the diet must provide Essential Amino Acids (EAAs) which are synthesized into proteins which can be structural, i.e. collagen in bone, keratin in hair, myosin and actinin muscle; metabolic enzymes, hemoglobin, protective antibodies and communicative hormones.Sources of protein include meat, fish, eggs and pulses. The diet needs to provide 8 EAAs as the body is unable to synthesis proteins without these molecules. 2 other amino acids are synthesized from EAAs so if the diet lacks the original EAAs these other two will not be present either. Phenylalanine is converted to tyrosine and methionine is converted to cysteine. Cells draw upon a pool of amino acids for protein synthesis which either come from dietary protein digested and absorbed in the gut and the breakdown of body protein such as muscle. However, unlike fats and carbohydrates there is no store of amino acids for cells to draw on, any amino acid in excess of immediate bodily requirements is broken down into urea and excreted. It is therefore important to maintain the dietary intake of protein everyday. If the body lacks protein, muscle wasting occurs as muscle is broken down.If protein is lacked in a diet a person develops kwashiorkor which is caused when high levels of carbohydrates are eaten to overcome the lack of protein in the diet. One symptom of kwashiorkor is the abnormal collection of fluid around the abdomen due to the lack of protein in the blood. The body cannot retain water by osmosis and fluid accumulates in tissues causing them to become waterlogged.Vitamin CategoriesVitamins cannot be synthesized by the body so must be supplied by diet. Vitamins have no common structure or function but are essential in small amounts for the body to be able to utilize other dietary components efficiently.Vitamins fall into two categories, fat soluble vitamins such as vitamin A, D, E and K which are ingested with fatty foods and water soluble vitamins such as the B group vitamins and vitamin C. Vitamins are known as micronutrients because only small quantities are required for a healthy diet, in fact fat soluble vitamins can be toxic in high concentrations, for example the body stores vitamin A, or retinol, in the liver as it is toxic if kept in high concentrations in the blood stream, a dose of more than 3300mg of vitamin A can be considered toxic. Water soluble vitamins such as vitamin C and B groups vitamins can be excreted in the urine if in excess in the diet.Vitamins AVitamin A is essential to the proper functioning of the retina in the eye and the epithelial tissues. A lack of vitamin A results in dry, rough skin, inflammation of the eyes, a drying or scarring of the cornea - xerophthalmia, which occurs when the secretion of lubricating tears is stopped, the eyelids become swollen and sticky with pus. Mucous surfaces of the eye may become eroded allowing infection to set in, leading to ulceration and destruction of the cornea. Night blindness - an inability to see in dim light can also occur. Rod cells in the retina of the eye detect light of low intensity, they convert vitamin A into a pigment, rhodopsin, which is bleached when light enters the eye. Rod cellsresynthesis rhodopsin, but if there is a deficiency of the vitamin, rod cells can no longer function and the result is night blindness. Epithelial cells use retinol to make retinoic acid, an intracellular messenger used in cell differentiation and growth. Without retinoic acid epithelial cells are not maintained properly and the body becomes susceptible to infections, particularly measles and infections of the respiratory system and gut.Xenophthalmia is common among children who's diets consist of mainly cereals with little meat or fresh vegetables, this is common in Indonesia, Bangladesh, India and the Philippines.Vitamins DVitamin D, or calciferol, is another fat soluble steroid vitamin which functions to stimulate calcium uptake from the gut and its deposition in bone. vitamin D acts as a hormone when converted by enzymes in the gut and liver into an active form of "active vitamin D", which stimulates epithelial cells in the intestine to absorb calcium. vitamin D is therefore essential in growing children's diets to enable the growth of strong bones. Without adequate amounts of vitamin D children can develop rickets, which is the deformation of the legs caused when they lack calcium to strengthen the bones. In adults a lack of vitamin D in the diet can lead to osteomalacia, a progressive softening of the bones which can make them highly susceptible to fracture.Vitamin D is made by the body when exposed to sunlight and is stored in the muscles, however, if the skin is rarely exposed to the sunlight or is dark little vitamin D is produced. Foods such as eggs and oily fish are all rich in vitamin D.Vitamins KVitamin K, phylloquinone, is found in dark green leafy vegetables such as spinach and kale. It is a fat soluble vitamin which is involved in the clotting process of blood. In the intestines bacteria synthesize a number of important clotting factors which need vitamin K. Without vitamin K cuts can fail to heal and internal bleeding can occur.Vitamins CVitamin C is a water soluble vitamin, known chemically as ascorbic acid. It is found in citrus fruits such as oranges and lemons, and also in potatoes and tomatoes. The main function of vitamin C is the formation of connective tissues such as collagen. It is also known to be an antioxidant which helps to remove toxins and aids the immune system. A lack of vitamin C leads to Scurvy, a condition experienced by sailors on long journeys when they did not have fruit in their diets. Scurvy causes painful, bleeding gums. As vitamin C is water soluble, it is not toxic in high doses as it can be excreted in the urine, very high doses can however cause diarrhea.Vitamins BB group vitamins have a wide range of roles acting as co-enzymes in metabolic pathways. They are found in most plant and animal tissues involved in metabolism,therefore foods such as liver, yeast and dairy products are all rich in B group vitamins. Deficiency of B group vitamins include dermatitis, fatigue and malformation of red blood cells.1. An adult needs about 12,000kJ of energy a day from ________.A. the cellB. the respiring process of carbohydratesC. fats in the cellD. a balanced diet2. Carbohydrates are ultimately absorbed into cells in the process of _______.A. digestionB. respirationC. oxidizationD. mobilization3.

Dreaming of something you’re worried about, researchers say, is the brain’s way of helping you rehearse for a disaster in case it occurs. Dreaming of a challenge, like giving a presentation at work or playing sports, can enhance your __48__. And cognitive neuroscientists have discovered that dreams and the rapid eye movement (REM) that happens while you’re dreaming are __49__ to our ability to learn and remember. Dreaming is a “mood regulatory system,” says Rosalind Cartwright, PhD, chairman of the psychology __50__ at Rush University Medical Center in Chicago. She’s found that dreams help people work through the day’s emotional quandaries. “It’s like having a built-in therapist,” says Cartwright. While we sleep, dreams __51__ new emotional experience to old memories, creating plaid-like patterns of old images laid on top of new ones. As she puts it, “You may wake up and think, What was Uncle Harry doing in my dream? I haven’t seen him for 50years. But the old and new images are __52__ related.” It’s the job of the conscious mind to figure out the relationship. In fact, dream emotions can help real therapists treat patients __53__ traumatic (创伤旳) life events. In a new study of 30 recently __54__ adults, Cartwright tracked their dreams over a five-month period, measuring their feelings toward their ex-spouses. She discovered that those who were angriest at the spouse while dreaming had the best chance of successfully coping with divorce. “If their dreams were bland,” Cartwright says, “they hadn’t started to work through their emotions and __55__ with the divorce.” For therapists, this finding will help __56__ whether divorced men or women need counseling or have already dreamed their troubles away.A. dealB. physicallyC. wakeD. performanceE. makingF. undergoingG. experienceH. divorcedI. determineJ. compareK. departmentL. consciousM. presentationN. linkedO. emotionallySection BDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.A few years ago a young mother watched her husband diaper (给…换尿布) their firstborn son. “You do not have to be unhappy about it,” she protested. “You can talk to him and smile a little.” The father, who happened to be a psychologist, answered firmly, “He has nothing to say to me, and I have nothing to say to him.”Psychologist now know how wrong that father was. From the moment of birth, a baby has a great deal to say to his parents, and they to him. But a decade or so ago, these experts were describing the newborn as a primitive creature who reacted only by reflex, a helpless victim of its environment without capacity to influence it. And mothers acceptedthe truth. Most thought (and some still do) that a new infant could see only blurry (模糊旳) shadows, that his other senses were undeveloped, and that all he required was nourishment, clean diapers, and a warm bassinet.Today university laboratories across the country are studying newborns in their first month of life. As a result, psychologists now describe the new baby as perceptive, with remarkable learning abilities and an even more remarkable capacity to shape his or her environment including the attitudes and actions of his parents. Some researchers believe that the neonatal period may even be the most significant four weeks in an entire lifetime.Far from being helpless, the newborn knows what he likes and rejects what he doesn’t. He shut out unpleasant sensations by closing his eyes or averting his face. He is a glutton for novelty. He prefers animate things over inanimate and likes people more than anything.When a more nine minutes out, an infant prefers a human face to a head-shaped outline. He makes the choice despite the fact that, with delivery room attendants masked and gowned, he has never seen a human face before. By the time he’s twelve hours old, his entire body moves in precise synchrony (同步发生) to the sound of a human voice, as if he were dancing. A non-human sound, such as a tapping noise, brings no such response.57. The author points out that the father diapering his first-born son was wrong because________.A) he believed the baby was not able to hear himB) he thought the baby didn’t have the power of speechC) he was a psychologist unworthy of his professionD) he thought the baby was not capable of any response58. According to the passage, which of the following is TRUE?A) A new infant can see only blurry shadows.B) A new infant’s senses are undevelopedC) All a new infant requires is nourishment, clean diapers, and a warm bassinet.D) A new infant is actually able to influence his or her environment59. What does the sentence “He is a glutton for novelty” probably mean?A) The newborn is greedy for new food.B) The newborn tends to overeat.C) The newborn always loves things that are new to him.D) The newborn’s appetite is a constant topic in no vels.60. According to the passage, it’s groundless to think that newbornsprefer________.A) a human face to a head-shaped outlineB) animate things to inanimate onesC) human voice to non-human soundsD) nourishment to a warm bassinet61. What is the passage mainly discussing about?A) What people know about newborns.B) How wrong parents are when they handle their babies.C) How much newborns have progressed in about a decade’s time.D) Why the first month of life is the most significant four weeks in a lifetime.Passage TwoQuestions 62 to 66 are based on the following passage.Mobile office is the mutual product of economic，scientific，and social progress.Mobile office has become a solution that provides users with convenient, prompt, safe, reliable, and reasonably priced communications and office faculty anywhere anytime via the support of mobile interconnection platform(MIP)and its applications systems. Using mobile office and WAP technology, people can do their work anywhere anytime, can send and receive data via terminals such as mobile phone, and palm computer, and can surf the Internet.When you leave your office to attend meetings or travel on business，what would happen to your business routine?Of course, faxes and e-mails would be still sent to your fax machine or e-mail box, but you cannot read them and make prompt reaction timely. When your clients need you to make some urgent modifications on your work and you are neither in the office nor carrying relevant documents, what can you do?Maybe you have to say “sorry” to the clients. But, your business will be affected，the clients will be unhappy and disappointed because of your delay，and you will lose a lot of business opportunities.In fact, very frequently, you need to check, reply, distribute, modify, or read some materials when you are not in your office. You must get out of this dilemma. The best solution to normally handle your business anywhere anytime and not to disappoint your clients is to let your office “move” with you. With the development of communications technology, mobile office has become simpler and smaller, and even can be realized via one mobile phone with data communications function. Thus, mobile office has already been put into your pocket, and office mobility has been realized.Mobile office has provided people with convenient, casual working environment, but at the same time it still has some unsatisfactory aspects such as mismatching equipment interface and inadequate battery. Nevertheless, we believe that with technical progress, people can certainly overcome all kinds of difficulties. Mobile office will realize the dream of completely free communication. Users will enjoy more colorful life and better working environment, and users’ living standard, working efficiency, and even enterprises’ production efficiency will certainly be immensely raised.注意：此部分试题在答题卡2上作答62. According to the passage, mobile office help you with the following except ________ .A) keeping update with the latest newsB) checking e-mails any time one wantsC) conducting internet surfingD) finding one’s true love in life63. Which of the following best expresses the main idea of the second paragraph?A) You would lose a lot of business opportunities if you always delay your work.B) You should read and reply faxes and e-mail timely.C) When you leave your office your business routine might be damaged.D) When you cannot meet the need of your clients you should immediately say sorry.64. When you let your office “move” with you, you __________ .A) will never let your clients downB) you don’t have to stay at office anymoreC) you then find the best way to handle your business anywhere anytimeD) you no longer face the dilemma between work and life65. It can be inferred from the passage that __________ .A) mobile office communication is very cost-consumingB) with the development of science, mobile office has eventually come to our lifeC) people had no convenient and reliable communications and office faculty beforeD) economic factors are essential in the operation of mobile office66. According to the author, mobile office _________ .A) would help achieve complete communication mobilityB) is too expensive to afford by small companiesC) has some fatal defects impossible to modifyD) is too complicated to operate in everyday businessPart V Cloze (15 minutes)Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A), B), C) and D) on the right side of the paper. You should choose the ONE that best fits into the passage. Then mark the corresponding letter on Answer Sheet 2 with a single line through the centre.For many people today, reading is no longer relaxation. To keep up their work, they have to read all kinds of materials. In _67_a job or advancing in one, the ability to read and comprehend _68_can mean the difference between success and failure. Yet the unfortunate fact is that most of us are _69_readers.Most of us develop poor reading _70_at an early age, and never get over them.The main deficiency _71_in the actual component of language itself-words. Take individually, words have _72_meaning until they are put together into phrases, sentences and paragraphs._73_, however, the untrained reader does not read groups of words. He laboriously reads one word at a time, often turning back to _74_words or passages.。

大学英语四级模拟试题及答案篇1Part Ⅱ Reading Comprehension (35 minutes)Directions: There are 4 passages in this part.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the correspondingletter on the Answer Sheet with a single line through the center.Questions 21 to 25 are based on the following passage:Some radio singals were heard in 1967.They were coming from a point in the sky where there was unknown star.They were coming very regularly,too:about once a second,if they were controlled by clock.?The scientists who heard the signals did not tell anybody else.They were rather afraid to tell in case they frightened people.The signals were coming from a very small body—no bigger,perhaps than the earth.Was that why no light could be seen from it?Or were the signals coming from a planet that belonged to some other star??There was no end to the questions,but the scientists kept the news secret.“Perhaps there are intelligent beings out there.”they thought,“who are trying to send messages to other planets,or to us?So the news was not given to the newspaper.Instead,the scientists studied the signalsand searched for others like them...Well,all that happened in 1967 and 1968.Since then scientists have learnt more about those strange,regular,radio signals.And they have told the story,of course.The signals do not come from a planet;they come from a new kind of star called a “pulsar””.About a hundred other pulsars have now been found,and most of themare very like the first one.?Pulsars are strong radio stars.They are the smallest but the heaviest stars we know at present.A handful of pulsar would weigh a few thousand tons.Their light—if they give much light—is too small for us to see.But we can be sure of this,no intelligent beings are living on them.21. The radio signals discussed in this passage____.A.were regularB.were controlled by a clockC.were heard in 1967 onlyD.were secret messages22. The radio singals were sent by____.A.a satelliteB.a planetC.a sky body which was unknown at that timeD.intelligent beings who were unknown at that time23. The scientists did not tell people about the signals because____.A.the singals stood for secret messagesB.people would ask them too many questionsC.they did not want to frighten peopleD.they stood for unimportant messages24. A pulsar is____.A. a small heavy star which sends out strong radio signals and cannot be seenB. a small heavy planet which sends out strong radio signalsand cannot be seenC. a small heavy satellite which sends out strong radio signals and cannot be seenD. a small intelligent being who sends out strong radio signals and cannot be seen 25. Which of the following is true?A.One of the pulsars found by scientists sends radio signals.B.Pulsar began to send radio singals in 1967.C.Scientists have searched for pulsars for many years but found none.D.Scientists have found many pulsars since 1967.Questions 26 to 30 are based on the following passage:Over vast areas of every continent,the rainfall and vegetation necessary for life are disappearing.Already more than 40 percent of the earth's land is desert ordesert?like.About 628 million people—one out of seven—live in these dry regions.In the past,they have managed to survive,but with difficulty.[ZZ(Z]Now largely through problems caused by modern life,their existence is threatened by the slow,steady spread of the earth's deserts.Scientists still do not understand all the complex problems of the desert,but there have been many ideas for saving the land.Sandi Arabia has planted 10 milliontrees to help keep the sand from taking over fertile areas.The Israelis are again using some of the water collection systems left by the ancient people in theNegev desert.They plan to water their orchards with the extra water.Some Sahel farmers still raise cattle on their poor farm land,but before the cattle are sold,they are taken to greener lands in the south to get fat.26. What is the article mainly concerned?A.The problem of spreading desert.B.The rainfall and vegetation in desert areas.C.The water collection systems.D.The difference between modern life and ancient life.27. “one out of seven” refers to____.A.more than a third of the lands' earthB.the percentage of the earth's land that is desert-likeC.the number of people who live in dry regionsD.a day of a week28. In paragraph 2,“they are taken to the greener lands in the south.”Theyrefers to____.A.the Sahel farm landB.the farmersC.the cattlesD.the trees29.

Because of these devices, ideas and news of events spread quickly allover the world. For example, within seconds, people can know the results of anelection in another country. An international football match comes into the homesof everyone with a television set.News of a disaster such as an earthquake or aflood can bring help from distant countries within hours, help is on the way. Because of modern technology like the satellites that travel around the world, information travels fast.How has this speed of communication changed the world? To many people,the world has become smaller. Of course this does not mean that the world is actually physically smaller. It means that the world seems smaller. Two hundred years ago,communication between the continents took a long time. All news was carried on ships that took weeks or even months to cross the ocean. In the seventeenth and eighteenth centuries,it took six weeks for news from Europe to reach America.This time difference influenced people's actions. For example, one battle, or fight, in the War of 1812 between England and the United States could have been avoided. A peace agreement had already been signed. Peace was made in England, but the news of peace took six weeks to reach America. During these six weeks, the large and serious Battle of New Orleans was fought. Many people lost their lives after a peace treaty had been signed.They would not have died if news had come in time.In the past,communication took much time than it does now.?There was a good reason why the world seemed so much larger than it does today.31. News spreads fast because of____.A.modern transportationB.new technologyC.the change of the worldD.a peace agreement32. According to this passage,____is very important to people in a disaster area.A.fast communicationB.modern technologytest newsD.new ideas33. Which of the following statements is true?A.The world now seems smaller because of faster communication.B.The world is actually smaller today.C.The world is changing its size.D. The distance between England and America has changed since the War of 181234. Two hundred years ago,news between the continents was carried____.A.by telephone and telegraphB.by landC.by airD.by sea35. The New Orleans Battle could have been avoided if the peace agreement had been signed____.A.by both sidesB.in timeC.in AmericaD.in EnglandQuestions 36 to 40 are based on the following passage:The concept of personal choice in relation to health behaviors is an important one.An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge.We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society.[ZZ)]The structure of American society allows us to make almost all our own personal decisions that may concern our health.If we so desire,we can smoke,drink excessively, refuse towear seatbelts,eat whatever foods we want,and live a completely sedentary life-style without any excuse.The freedom to make such personal decisions is a fundamental aspect of our society,although the wisdom of these decisions can be questioned.Personal choices relative to health often cause a difficulty.As one example,a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.?A multitude of factors,both inherited and environmental,influence the development of health?related behaviors,and it is beyond the scope of this text to discuss all these factors as they may affect any given individual.However,the decision to adopt a particular health-related behavior is usually one of personal choices.There are healthy choices and there are unhealthy choices.In discussing the moral of personal choice,Fries and Crapo drew a comparison.They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide.[ZZ)]Thus,for those individuals who are interested in preserving both the quality and quantity of life,personal health choices should reflect those behaviors that are associated with statistical probability of increased vitality and longevity.36. The concept of personal choice concerning health is important because____.A.personal health choices help cure most illnessesB.it helps raise the level of our medical knowledgeC.it is essential to personal freedom in American societyD.wrong decisions could head to poor health37. To “live a completely sedentary life?style”(Para. 1) inthe passage means____.”A.to live an inactive lifeB.to live a decent lifeC.to live a life with complete freedomD.to live a life of vice38. Sound personal health choice is often difficult to make because____.A.current medical knowledge is still insufficientB.there are many factors influencing our decisionsC.few people are willing to trade the quality of life for longevityD.people are usually influenced by the behavior of their friends39. To knowingly allow oneself to pursue unhealthy habits is compared by Fries and Crapo to____.A.improving the quality of one's lifeB.limiting one's personal health choiceC.deliberately ending one's lifeD.breaking the rules of social behavior40. According to Fries and Crapo sound health choices should be based on____.A.personal decisionsws of societyC.statistical evidenceD.opinions of friendsPart Ⅲ Vocabulary and Structure (20 minutes)Directions:There are 30 incomplete sentences in this part.For each sentence there are four choices marked A),B),C) and D).Choose the ONE answer that best completes the sentence.Then mark the corresponding letter on the Answer Sheet with a single line through the center.41. ____he thought of it,the stars seemed always large and clear before the dawn of Christmas Day.A.As forB.Now thatC.BecauseD.As soon as42.

constantly juggling multiple tasks and responsibilities, and effective time management can help them stay organized and productive One of the key aspects of time management is setting priorities By identifying the most important tasks and focusing on them first, individuals can make the most of their time and achieve their goals more efficientlyB Another important strategy for time management is breaking tasks into smaller, manageable steps This can make large and overwhelming projects seem less daunting and more achievable It also allows for better planning and allocation of time Additionally, setting deadlines for each step can help create a sense of urgency and keep one motivatedC Scheduling is also an essential part of time management Creating a daily or weekly schedule and sticking to it as closely as possible can help ensure that all necessary tasks are completed However, it's important to be flexible and allow for unexpected events or changes in priorities Sometimes, unforeseen circumstances may require adjusting the scheduleD Technology can be a useful tool for time management There are numerous apps and software available that can help track time spent on different activities, set reminders, and organize tasks However, it's important not to become overly dependent on technology and to still have the ability to manage time without itE Time management also involves avoiding distractions Social media, email, and other forms of entertainment can easily consume a lot of time if not used mindfully By being aware of these potential distractions and setting limits on their use, individuals can stay focused on the task at handF Learning to say ＂no" is another important aspect of time management It's easy to take on too many commitments and spread oneself too thin By being selective about what one agrees to do, individuals can avoid overloading their schedule and have more time for the most important tasksG Finally, it's important to take breaks and rest Working nonstop can lead to burnout and decreased productivity Regular breaks can rejuvenate the mind and body, allowing for better performance in the long runH Good time management skills are not developed overnight It takes practice and consistency By consistently applying these strategies and being mindful of how one spends their time, individuals can gradually improve their time management abilities and lead a more balanced and productive lifeI Time management is not only important for personal productivity but also for maintaining a healthy worklife balance By effectively managing time, individuals can have more time for hobbies, family, and relaxation, reducing stress and improving overall wellbeingJ It's also important to evaluate and reflect on one's

For questions 1-7, choose the b est answer from the choices marked A), B), C) and D). For questions 8 to10, com plete the sentences with the information given in the passage.Using the mind to fight diseasesPsychology has a new application in the field of medicine. Many doctors, toget her with their patients, are looking for alternative methods of treatment of physical problems. In large hospitals and research centers, modern methods of therapy see m to focus on the physical disease without considering the patients' mental state. Patients may feel that they are being treated impersonally, like broken machines. S ome doctors have recognized this as a problem. They are now using psychological therapy with patients to use their own minds to fight their diseases. Because the patient is working with the medicine and the doctors against the disease, his or he r attitude changes. The patient does not wait for the medicine and treatment to cur e him or her, but instead the patient joins in the fight.Mental therapyThe doctor knows that a disease affects a patient's body physically. The body of the patient (in this case, a man) changes because of the disease. He is not o nly physically affected, but as the physician knows, he also has an emotional resp onse to the disease. Because his mind is affected, his attitude and behavior chang e. The medical treatment might cure the patient's physical problems, but the patient 's mind must fight the emotional ones. For example, the studies of one doctor, Car l Simonton, M. D., have shown that a typical cancer patient (in this case, a woma n) has predictable attitudes. She typically feels depressed, upset, and angry. Her s elf-image is poor and she feels self-pity. As a result, her behavior changes. Becau se of her constant depression, she acts unfriendly toward her family, friends, doctor s, and nurses. Such attitudes and behaviors prevent the patient from getting well. Therefore, a doctor's treatment must help the patient change her attitudes. Simonton's method emphasizes treatment of the whole patient by treating both the body an d the mind.The attitude of a cancer patient who is receiving radiation therapy, an X-ray tr eatment, can become more positive. The physician who is following Simonton's psy chological treatment plan suggests that the patient imagine that he or she can see the tumor（肿瘤）in the body. In the mental picture, the patient "sees" a powerful beam of radiation like a million bullets of energy. The patient imagines the beam hi tting the tumor cells and causing them to shrink. For another cancer patient, Dr. Si monton might make another suggestion. This patient, with a different kind of cancer, needs to take capsules and pills several times a day. The doctor asks the patient to imagine the medicine going from the stomach into the bloodstream and to the cancer cells. The patient imagines that the medicine is like an army fighting the dis eased cells and sees the cancer cells gradually dying. His or her blood carries aw ay the dead cells. Both the medical therapy and the patient's positive attitude fight the disease.Doctors are not certain why this mental therapy works. However, this use of p sychology does help some patients because their attitudes about themselves chang e. They become more confident because they use the power within their own mind s to help stop the disease.Suggestion therapyAnother application of using the mind to help cure disease is the use of sugg estion therapy. Before making the suggestion, the doctor helps the patient to conce ntrate deeply. The patient (in this case, a man)thinks only about one thing. He bec omes so unaware of other things around him that he seems to be asleep. He is s aid to be in a trance （催眠状态）. Then the physician makes "a suggestion" to the patient about the medical problem. The patient's mind responds to the suggestion even after the patient is no longer in the trance.. In this way, the patient uses his mind to help his body respond to treatment.Suggestion therapy helpful for both adults and childrenDoctors have learned that this use of psychology is helpful for both adults and children. For example, physicians have used suggestion to help adults deal with t he strong pain of some disease. Furthermore, sometimes the adult patient(in this c ase, a woman) worries about her illness so much That the anxiety keeps her from getting well. The right suggestions may help the patient to stop being anxious. Su ch treatment may help the patient with a chronic（慢性的）diseases. Asthma （哮喘）is an example of a chronic disorder. Asthma is a disease that causes the patient t o have difficulty in breathing. The patient starts to cough and sometimes has to fig ht to get the air that he or she needs. Psychology can help relieve the symptoms of this disorder. After suggestion therapy, the asthma patient breathes more easily.Physicians have learned that the psychological method is very useful in treatin g children. Children respond quickly to the treatment because they are fascinated b y it. For example, Dr. Basil R. Collison has worked with 121 asthmatic children in Sydney, Australia, and had good results. Twenty-five of the children had excellent r esults. They were able to breathe more easily, and they did not need medication. Another forty-three were also helped. The symptoms of the asthma occurred less fr equently, and when they did, they were not as strong. Most of the children also fel t better about themselves. Doctors have also used suggestion to change habits like nail-biting, thumb-sucking, and sleep-related problems.Response from the medical worldMany professional medical groups have accepted the medical use of psycholo gy because they recognize its value. Nobody knows how suggestion works; howeve r, doctors have learned that psychology has important applications in medicine.1. What does the passage mainly discuss?A) How to use the mind against disease.B) How modern methods of therapy focuses on the physical disease.C) Response from the medical world.D) How suggestion therapy benefits to adults and children.2. How does psychological therapy work?A) The patient waits for the medicine and treatment to cure him.B) The doctor uses medical treatment to cure the patient's problems.C) The doctor, the medicine, and the patient work together to fight disease.D) The patient uses his minds to cure himself.3.

D.?A) The medical treatment can cure the patient's mental disease.B)The treatment of a patient by treating the body and the mind is necessary.C)The mental treatment is more important than medical treatment.D)Few patients have emotional response to the disease.4.
