While social media has its benefits, such as connecting people from all around the world and providing a platform for sharing information and ideas, it also has negative impacts on society.One of the positive aspects of social media is its ability to bring people together. It allows individuals to stay in touch with friends and family, no matter where they are located. Social media also provides a platform for sharing news and information quickly and easily, which can be beneficial in emergency situations.However, social media also has negative impacts on society. One of the biggest concerns is the spread of fake news and misinformation. With the rise of social media, it has become increasingly difficult to distinguish between reliable sources and fake news. This can lead to a misinformed public and have serious consequences for society.Furthermore, social media can have a negative impact on mental health. Studies have shown that excessive use of social media can lead to feelings of loneliness, anxiety, and depression. The constant comparison to others on social media can also lead to low self-esteem and self-worth.In conclusion, while social media has its benefits, such as connecting people and sharing information, it also has negative impacts on society, such as the spread of fake news and negative effects on mental health. It is important for individuals to use social media responsibly and critically evaluate the information they see online.以上是一份英语四级考试题目模拟及答案,希望对大家备考有所帮助。

The cases were confirmed after strict tests in the World Health Organization (WHO) laboratories were completed, a spokesperson of the ministry said.One of the patient, a 20-year-old restaurant waitress, has been discharged from the hospital after full recovery. None of the people that have contacted with her show SARS symptoms and all of them have been released from quarantine, according to the spokesperson. She was identified as a suspected case on January 8.The other patient, a 35-year-old private businessman, is in a stable situation and has maintained a normal temperature for 11 days, the spokesperson said. He was identified as a SARS suspect January 13.The ministry has informed WHO on the latest developments and Guangdong health authorities have also notified Hong Kong and Macao authorities on the current SARS situation.The spokesperson pointed out that, up to now, Guangdong has reported three SARS cases since the epidemic was declared contained last July, but none of them is highly infectious and recovered quickly.However, the spokesperson warned against negligence over the disease and called on all level of governments to be on high alert, taking all kinds of measures to prevent another SARS outbreak.The season's first confirmed case, a 32-year-old television producer, was released from hospital last week.WHO says SARS comes from animalsAll three recent SARS related cases in Guangzhou are believed to have been infected with the potentially deadly virus by animals, WHO experts say.Dr Robert Breiman: No repeat of last year's outbreak.A joint-team of experts on a mission to track down the deadly virus source believed it has traced the cause of the infection in the first confirmed SARS case.The research team consists of members of the WHO, the Chinese Ministry of Health,China Centre of Disease Control and Prevention (CDC), and the Guangdong CDC. The South China University of Agriculture is also on board."We have good reason to believe that animals are the reservoir of the ultimate source of SARS,'' Dr Robert Breiman, an epidemiologist with WHO and the United States CDC, said on Friday. Breiman is the team leader. The WHO team will head for Beijing on Saturday after spending a week on its investigation in Guangzhou.The SARS virus has been detected in animal-holding cages in the restaurant in which the 20-year-old restaurant waitress had worked, Breiman said.It was also found in the two wild animals trading markets in the nearby area. And the female patient served dishes made from civets and other animals, Breiman said.The virus separated from the confirmed SARS patient was nearly identical with that from civet samples, according to Guangdong CDC. Civets are a species of wild cats caught and served at area restaurants as a delicacy. Amazingly, the restaurant owner, who has cooked wild animals like the civet for decades, was quarantined for observation but never showed signs of SARS.Up to now, there is no record of the third patient having contacts with wild animals. However, scientists deduce that animals are the most possible source of the disease. “By and large, most of the diseases that have appeared in the past 10 years have, in the end, turned out to be from an animal source,” Breiman said.“Understanding the potential of animal reservoirs for disease is an important part in any investigation for the new diseases,” he added.The SARS that has infected the known patients this year has seemed a less virulent form than last year, the researcher said, infecting people who come into contact with animals, but not always.“Very possibly, it's a variation virus that isn't transmittable from person to person,” he said.注意:此部分试题请在答题卡1上作答;8-10题在答题卡1上。

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。

You should write at least 150 words following the outline given below.1.大学校园内多种证书旳报考十分火热2.大学生考证旳利弊3.考证面前,我旳选择The Popularity of Getting Certificates on CampusPart ⅡReading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1.For questions 1-7, choose the best answer from the four choices marked A), B), C) and D). 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.

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. How many ideas for saving the land are described?A.Five.B.Two.C.Four.D.Three.30. Which of the following statements is true, according to the passage?A.The earth's desert are slowly spreading.B.One out of 10 people lives in dry regions.C.Their life in the desert is threatened now by traditional problems.D.New water wells can solve the problem in Africa's desert.Questions 31 to 35 are based on the following passage:Telephone, television, radio, and telegraph all help people communicate witheach other. 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.

模拟测试试题参考答案作文Will E-books replace traditional books?Recent decades have seen the rapid development of information technology, and thereby E-books have wound their way into our daily life. Because of the wide and quick popularity of E-books, there has been an increasing controversy over the question of whether E-books will replace traditional books or not.Many people hold the idea that it will not take long for E-books to replace traditional books because E-books have quite a few advantages over traditional ones. First, E-books are more accessible to readers, because the readers just need to log onto the internet and read online. Second, thanks to the advanced technology, the cost of E-books is much lower, so it takes readers far less money to buy E-books. Last but not the least, reading E-books has developed into part of our daily life, which is particularly appealing to young users, who are the body part of the users of electronic products.As far as I’m concerned, it is not likely for E-books to replace traditional books for lots of reasons. For example, long time of reading E-books will do more harm to our eyes, and readers will find themselves more accessible to printed materials because computers and the internet haven’t yet been popularized to ever y corner of our life.阅读 1.

It is a common problem and it is getting worse. Airport delays make people angry and cost the country billions in lost work time.The Federal Aviation Administration or FAA is the government agency that oversees air travel. They studied the problem of airline delays.They found eleven major problems and proposed eleven ways to fix them. Some of the problems are caused because different regions of the country do things differently. Also, more planes are flying. A strong economy has more people using airplanes to get round. Airplanes are a form of mass transportation now, like trains and buses were in the past. More planes in the airport cause delays. Weather is another main reason for delays. Weather causes about 70 % of delays. Fog or freezing rain can cause delays.The first thing the FAA wants to do is take control away from the regions during heavy traffic times and bad weather. A national center would make decisions on things that affect the whole country. The FAA also wants to put more distance between planes in the sky when the weather is bad. This rule could cause even more delays.The FAA knows that their solutions will not cure the problems with airport delays. But, they hope to make things better. There are just too many planes, too few traffic controllers, and not enough new technology.26.What is the problem studied by FAA?27.What is the main cause of airline delays according to the study?28.Why is it likely that the FAA will create more delays?Passage TwoOn March 26, 2000, the Kingdome in Seattle was destroyed. It was taken down to make room for a new stadium. The blast from the falling Kingdome caused the Earth to shake as if an earthquake had happened.Scientists placed more than 200 seismic reorders in the earth to measure the movement. They found which parts of the city shook the most. This information helped them predict which parts of the city would be damaged in a real earthquake.On February 28, 2001, the real thing happened. The earthquake was 6.8 on the Richter scale. It damaged the same parts of Seattle that scientists had predicted from the Kingdome blast. It was a slab quake. It started deep in the earth, 37 miles below the surface on the Juan de Fuca plate.Scientists have learned that deep earthquakes have very few aftershocks. The earthquake had only four. Another earthquake in California that was close to the surface had over 120 aftershocks. Scientists do not know why the deep earthquakes have fewer aftershocks.Scientists plan to set off explosive in the ground near Seattle aimed at the slab. The shockwaves from the blast will bounce off the slab and give them an idea of where the plate is and how it is moving. This will give them more information in case another real earthquake hits the area.29.How was the Kingdome in Seattle destroyed?30.Why did scientists measure the collapse of the Kingdome?31.What is most puzzling to scientists about the earthquake?32.What are scientists planning to do according to the passage?Passage ThreePeople have always looked to the sky and wondered about what they saw. As centuries of discoveries flew by, it became obvious that humans would not be content to just gaze at the solar system. We wanted to blast off into it as well.Once again, technology allowed us to accomplish our goal. On October 4, 1957, a Soviet rocket sent the first man-made satellite into space. It was called Sputnik, the Russian word for “traveler”. Even though Sputnik was nothing more than a small aluminum ball with a radio inside, it started a whole new era of space exploration.In May 1961 President John F. Kennedy challenged American scientists to land a person on the moon before the end of the 1960s. In the quest to do this, scientists faced many obstacles. For example to get a spaceship all the way to the moon and back would demand a rocket engine powerful enough to make the trip.Scientists realized that it would be difficult for one heavy rocket loaded with fuel to reach the moon. Instead, they decide to use a multistage rocket. When the fuel in one stage of a multistage rocket is used up, that stage falls away. This makes the rockets lighter, and the engine of the next stage can ignite and thrust the rocket even faster and higher.As you know, Americans successfully landed on the moon in July 1969. Since then our knowledge of the solar system has increased dramatically.33.Which of the following is NOT true of the first manned space flight?34.What is the key to building a spacecraft bound for the Moon?35.How could the scientists have made the trip to the Moon a success?The (36) highest degree that a student can earn is a doctorate. Some doctorates are (37) professional degrees, as opposed to a degree based on research. Medical students, for example, receive an M.D., fr om the Latin “medicinae doctor”. Future (38) lawyers receive a J.D., for “juris” or “jurum” doctor, meaning a doctor of law or laws.Someone with a PhD is a “doctor of philosophy. Many people earn a PhD, yet no t many are philosophers. The name has (39) survived since the Middle Ages when many areas of study were called philosophy.Students can receive a PhD in (40) engineering, social work education, music, history and a lot of other areas. (41) Requirements can differ from one university to another and from one area of study to another. But the National Science Foundation says American doctoral education is (42) organized around a research experience.A PhD usually requires at least three years of (43) full-time study after a bachelor’s degree. Usually, PhD candidates must have a master’s degree before they sit for special examinations. They have to carry out original research and (44) present their findings by writing a long paper that they have to defend before a group of experts.(45) Every year, the federal government collects information on research doctorates awarded in the United States. More than forty-three thousand students received a research doctorate in 2005.(46) Close to one-third of those doctorates went to foreign students in the United States on a temporary visa. Most of them studied engineering, physical science or life science.。
