高三英语一轮复习课时作业12：Unit 2 Healthy eating
Unit 2 Healthy eatingⅠ.阅读理解AGood health is the most valuable thing a person can have, but one cannot take good health for granted(认为……理所应当). It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food，get enough sleep, and exercise regularly.Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料)．Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质)，like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (人的个性)．Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命)．Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.1．According to the passage, ________.A．we should always keep fitB．if we were healthy, we could spend our days in doing things with less sleepC．one can eat a lot to stay in good shapeD．one needn't take any exercise if he is healthy2．In order to keep good health, ________.A．we should eat a lot of sweetsB．one needs a large amount of fatC．people should eat according to the foods nutritionD．we must try to sleep now and then3．Eating more and sleeping less ________.A．can keep healthyB．is no good for youC．gets you more energyD．will keep your personality4．The writer explains ________in this passage.A．how to eatB．the importance of doing exerciseC．how to keep healthyD．what to eat5．The title of the article should be ________.A．Eating and ExercisingB．How Vitamins Work in Man's BodyC．Staying HealthyD．Sleeping WellBAlmost every day, we discuss the topic of health, especially for kids. But what is health? “Health” means eating well, ge tting enough exercise, and having a healthy weight. Let's read the following rules. They can help you stay healthy.①Eat a_variety_of foods, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the nutrition(营养) we need by eating different kinds of food, especially fruit and vegetables.②Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty of calcium(钙) to grow strong bones, and milk has a lot of it. Every day, you should drink at least three cups of milk (1300 milligrams of calcium), when you are 9 years old or older. You should also try to have less sugary drinks, like soda and coca. They include a lot of sugar. Sugar just includes calories, not important nutrition.③Listen to your body. When you are eating, notice how your body feels. When your stomach feels comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can make you unhealthy and fat.④Limit(限制) screen time. What's screen time? It's the amount of time you spend watching TV, movies, and playing computer games. The more time you spend on these sitting-down activities, the less time you spend playing sports, like basketball, and doing other activities like bike riding and swimming. Try to spend no more than 2 hours a day on screen time.6．In this passage, “health” includes all of the following EXCEPT ________.A．eating wellB．wearing comfortablyC．having a healthy weightD．doing more exercise7．The underlined phrase “a variety of” means ________.A．plenty B．a lot ofC．the rest of D．all kinds of8．As kids, we should drink at least ________ to grow strong bones.A．three cups of milk B．four cups of milkC．two cups of milk D．one cup of milk9.What's the main idea of the passage?A．How to eat healthily.B．Eating and playing are both important.C．Advice for staying healthy.D．Health is very important.Ⅱ.完形填空The Little AngelSally jumped up the moment she saw the surgeon come out of the operating room.

A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(释放)poisons that make people sick.Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.11．Which of the following statements is NOT true?A．Food when poisoned can make people sick.B．Food poisoning means death.C．Food poisoning comes in varieties.D．Food poisoning can be serious.12．We know from the passage that the symptoms of food poisoning________.A．are always accompanied by a feverB．are too common to be noticedC．can be noticed within hoursD．can be ignored13．Food poisoning can be caused by all the following EXCEPT________.A．some chemicals B．low temperaturesC．some tiny living things D．certain natural materials14．From Paragraph 5，we can learn that________.A．mushrooms should not be eatenB．vegetables are safer than meat and seafoodC．natural poisons are more dangerous than chemicalsD．different types of food should be handled differently15．It can be inferred from the passage that________.A．natural materials are safe in food processingB．chemicals are needed in food processingC．food poisoning can be kept under controlD．food poisoning is out of controlBEvery person learns at least one language in his childhood that is routinely used for speaking and writing.However, many people are fond of learning two or more languages.There are numerous benefits of being bilingual such as an improvement in linguistic abilities as well as betterment of cognitive (认知) flexibility such as divergent thinking, concept formation, verbal abilities and general reasoning.Many people have the capacity to learn a second language.It may be another language in the same country or totally different language from another country.Nowadays, institutes and schools offering foreign language courses are popping up throughout the world.While learning another language, you need to understand its basic grammar and improve vocabulary.Being bilingual offers greater sensitivity to language, more flexibility in thinking and a better ear for listening.It also improves a person's understanding for the native language.It opens the door to other cultures.Moreover, knowledge of other languages increases the career opportunities, offering several job options.The bilingual people can have some specific advantages in thinking.They have two or more words for each idea and object and can develop a creative thinking and an ability to think more flexibly.The bilinguals are aware about which language should be spoken with which person in a particular situation.Therefore, they are more sensitive to the needs of the listener, than the monolingual people.Being bilingual has a positive effect on intellectual growth.It enhances and enriches a person's mental development.The bilinguals are better at IQ tests as comparedto the monolinguals.What is more, being bilingual may keep your mind young.Juggling two languages as a child can slow mental decline.The bilinguals are able to switch between different languages and talk to different people in various languages.It increases a sense of self－esteem.Being bilingual creates a powerful link in different people from different countries.The bilinguals tend to show a higher performance in examinations and tests.The bilinguals enjoy reading and writing in different languages.They can understand and appreciate literatures in various languages.It gives a deeper knowledge of different ideas and traditions.It helps improve the ways of thinking and behaving.The pleasures of reading poetry, novels and magazines as well as the enjoyment of writing to family and friends are doubled for bilinguals.16．Which is the best title of the passage?A．We should be bilingualB．Learning languages is of great helpC．Advantages of being bilingualD．Mastering languages17．Which of the following is not the cognitive benefits of being bilingual?A．It makes a person think creatively.B．It makes a person more sensitive to the listener's needs/demands.C．It improves and enriches a person's mental development.D．It does good to a person's character.18．According to the author, being bilingual can ________.A．be happier than the monolingual peopleB．develop a strong relationship between peopleC．have a better understanding of the listenerD．build up a person's confidence19．It can be inferred that when hunting for a job, ________.A．a person can increase his own sense of self－esteemB．graduates are offered more opportunitiesC．the bilinguals have an advantage over othersD．the bilinguals can understand the employers better20．Whom is the passage written to?A．Foreign students.

the end her sickness had the last word.One day John took out a folded piece of paper from hiswallet.He found it when he tidied up some drawers at home.It wasa small love letter Janet had written.The note could look likea school girl’s scrawls (不工整的字迹) about her dream guy.Butthe small letter was written by a woman who had had sevenchildren，who fought for her life and who probably only had a few months left to live.It was a beautiful recipe (秘诀) for how to keep a marriage together.Janet’s description of her husband begins thus：“Loved me.Took care of me.Worried about me.”John showed great consideration for Janet.Sometimes he came home in the evening to find her in low spirits.In no time he got her into the car and drove her to her favorite restaurant.“Helped me when I was ill，” the next line reads.Perhaps Janet wrote this while the cancer was in the stage where everything is－almost－as it used to be，before the sickness broke out，and where it doesn’t hurt to hope that everything is over，maybe forever.“Stood by my side.”“Made sure I had everything I needed，” she goes on to write.After that she has turned over the paper and added：“Warmth.Humor.Kindness.Thoughtfulness.” And then she writes about the husband she has lived with and loved the most of her life：“Always there for me when I needed you.”The last words she writes sum up all the others：“Good friend.”I stand beside John now，and cannot pretend to know how it feels to lose someone who is as close to me as Janet was to him.“John，” I ask.“How do you stick together with someone through 38 years －not to mention the sickness?

At this point, of course, any pill for humans is but a twinkle(闪烁) in the eye of every medicine company's CEO.More tests are to be made, and eventually humans will be introduced in the test.But for now，unfortunately，control in diet is still the key.11．What does “such a surprising task” in Paragraph 4 refer to?A．Eating a lot of food while losing weight.B．Burning up fat very quickly.C．Controlling the diet.D．Having a rich fantasy life.12．Why did the author say he/she had to be a mouse in Paragraph 4?A．Because a mouse can lose weight no matter how much it eats.B．Because the weight losing tests were made on the mouse.C．Because the mouse has a very good metabolism.D．Because the author wants to try the food without the enzyme.13．In the experiment, the mice without those enzymes________.A．were in good conditionB．put on weightC．became weakD．could not have baby mice14．What does the author want to show through the last two paragraphs?A．You can be free of guilt when having big dinners.B．Scientists cannot find the key to identifying theenzyme.C．Don't overeat before the test is made on humans.D．It is unnecessary to control weight at present.BThese fast food restaurants constantly remind us of the American fondness with hamburgers，chips and pizza.But America's reputation as the home of fast food is under threat from the British，according to a research carried out by the BBC in 13 nations among 9,000 people.Despite fears over obesity，the study found the British are more obsessed with junk food than any other nation.Almost half of British respondents(参与调查者)said they enjoyed fast food too much to give it up. About 44 percent in the US claimed they would be unable to stop eating burgers，pizzas and chicken wings，making the country second in the world's junk food league. The third place went to the United Arab Emirates，where 35 percent are junk-food lovers.The research also found that attitudes to food and weight vary wildly around the world. Those in the UK and US believed lack of self-discipline was the main factor behind growing waistlines(腰围). They can't deny themselves that hamburger or extra piece of pizza，but “make themselves feel better by washing it down with a diet coke”，the study suggested.The French，on the other hand，seem to keep a watchful eye on their weight. They get on the scales every day. Only 19 percent of the French surveyed admitted a fondness for fast food.Thierry Pailleux，of France，from the market research firm that conducted the poll，said the French valued the combination of good food and company. Sharing classic food and time with lovedones is key to the French sensibility. “French people take care of their image as a matter of course. Being thin is part of our culture and a point of pride. We are known for it，” said Pailleux.“On top of this，there is increasing awareness of the devastation(伤害)that obesity can cause to one's health.”15．What's the main idea of the passage?A．A study of different attitudes towards fast food.B．How popular fast food is in foreign countries.C．Different countries' attitudes towards food and body weight.D．A study of how popular fast food is in foreign countries.16．The research shows that ________.A．Americans are proud of the fast foods they eatB．those British who love fast foods do not care about their body weightC．the British would like to think that other foods they eat make up for eating occasional fast foodD．most Americans believe the enjoyment of food is more important than its possible effect on their waistlines17．What's the meaning of the underlined word “obsessed” in the second paragraph?A．Crazy. B．Obese. C．Opposed. D．Neutral.18．Why are，according to Thierry Pailleux，the French less obsessed with fast food than the British and Americans？Because ________.A．they value their imageB．they have better foods than other countriesC．they value self-disciplineD．they are afraid of having an unhealthy dietⅢ.完成句子阅读下列各小题，根据每句后的汉语提示，用句末括号内的英语单词完成句子。

People who increased their intake over just six weeks developed a healthy glow and appeared more attractive, researchers found. Scientists at St Andrews University found eating them slightly increased yellow and red pigments in the volunteers' skin. They monitored the food intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks. Increasing their intake of greens by 2.9 portions a day was found to make the person look more healthy and an extra 3.3 portions could enhance their attractiveness, when their photographs were rated by others.Fruit and vegetables are rich in carotenoids (类胡萝卜素), which are known to protect against cell damage from pollution and UV rays, and can also prevent agerelated diseases including heart disease and cancer. But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange, it was not known a small increase was perceptible (被觉察) to others and was seen as appealing.A camera measured changes to the skin's redness, yellowness and lightness, and found it significantly changed in people who naturally increased their intake. These changes were not evident in three weeks. Using light sensors, the researchers showed these red and yellow hues were linked with the levels of carotenoids in their skin. There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene (番茄红素), which gives tomatoes and red peppers their red colour andbetacarotene found in carrots as well as broccoli, squash, and spinach. Skin colour is also affected by chemicals called polyphenols (多元酚), found in apples, blueberries and cherries, which cause blood rush to the skin surface.11．What do we know from the research?A．If you take in a little more fruit and vegetables, you will obviously look more attractive in three weeks.B．The researchers took the pictures of 35 people in the research at different stages.C．Increasing your intake of greens by 2.9 portions a day can greatly improve your health.D．People who increased their intake of greens by 3.3 portions a day were found the most attractive after six weeks.12．Which of the following is NOT the function of carotenoids?A．They can protect against cell damage from pollution and UV rays.B．They can prevent heart disease and cancer.C．They can prevent agerelated diseases.D．They can keep you in good health.13．Which of the statements is NOT true according to the passage?A．We've already known eating extreme amounts of carrots can turn skin orange.B．We knew in the past that eating a few more carrots could make us look appealing.C．The research showed the improvement in skin is linked with the levels of carotenoids in it.D．Among hundreds of carotenoids, lycopene is thought to have the most dramatic effect on the skin.14．We can infer from the passage that ________．A．skin's redness, yellowness and lightness make a person look more healthy and attractiveB．carotenoids have the same effect as lycopeneC．it is carotenoids that give tomatoes and red peppers their red colourD．both betacarotene and polyphenols affect skin colour by causing blood rush to the skin surface15．Which can be the best title of the passage?A．Eating fruit and vegetables does goodB．Fruit and vegetables are rich in carotenoidsC．How to become attractiveD．Eating fruit and vegetables makes you look goodBIf you walk around any large city, you'll find a coffee shop on every corner. Many shops offer comfortable sofas, large screen televisions and sometimes even live music. More and more teenagers are hanging out there. My preteen has already done so after school once a month but she always orders fruit juice. I think she would drink coffee sooner or later, so I started doing some research online.I found out that coffee in moderation can be safe. But one thing that was constant online was the chance of becoming addicted to coffee. Coffee is one step up from sodabut still not as dangerous as energy drinks or alcohol. Still, any addiction is hard to break. So I needed to come up with a plan that would protect my child.Coffee shops offer a safe place for teens to hang out. As like anything else you let your children do, you need to set limits. Drinking coffee while socializing once or twice a week will not cause a severe caffeine addiction. However, you should avoid allowing a cup of coffee every morning and ensure they get adequate sleep each night, which will make them less likely to feel the need to drink coffee.As parents we have responsibility to set a good example. If you're addicted to caffeine, it's time to start monitoring your intake. If you drink much water and keep healthier drink options in your fridge and at your dinner table, your teen will follow you. I drink much water and so do both my children. My_kids_learn_more_from_watching_me_do_things_than_they_will_ever_learn_from_my_ verbal_teaching.As a mother, I'm ready to allow my child to try coffee, and we'll talk about it and discuss the pros and cons of consuming this. I feel open communication is vital in helping them make good decisions. Although, the decision to drink coffee doesn't pose the same dangers as underage drinking, it still deserves a thoughtful conversation.16．The author began to do research on coffee in order to ________．A．offer some good advice to coffee shopsB．guide her daughter to drink coffee properlyC．stop her daughter hanging out in coffee shopsD．let her daughter believe that fruit juice is healthy17．What might be the content of the plan the author would come up with?A．How her daughter can keep safe.B．Why coffee is as dangerous as alcohol.C．How her daughter can avoid caffeine addiction.D．What benefits her daughter can achieve from coffee.18．According to the text, if teens have enough sleep, they ________．A．will not ache for coffee that muchB．will not hang out in coffee shopsC．will not drink coffee for everD．will drink water instead of coffee19．What does the underlined sentence in the fourth paragraph imply?A．The author's children don't like to talk with her.B．The author thinks a good example functions better.C．The author is living in harmony with her children.D．The author doesn't want her children to learn from her.20．Which of the following statements agrees with the author's opinions in the text?A．Teens should stop from entering coffee shops.B．Coffee shops should not offer many options to teens.C．Teen's activities in coffee shops should be limited strictly.D．Parents should not force their children to stop drinking coffee.Ⅲ.读写任务阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

ill in bed and can't get up, we will be thankful for the nurse who helps us get clean.While I am not a nurse, and have never given anyone a bath, I would imagine that it would take a lot of sympathy and patience to do so.Yet those who attended the International Conference on Intelligence Robots and Systems Conference last month were introduced to Cody, a robot that can bathe human beings.The robot has a base that can be turned to all directions, two humanli ke arms, and flexible wrists (腕)．It uses a camera and laser range finder to locate parts of the human body.It then uses bath gloves to clean with a little pressure.The robot was designed at the Georgia Institute of Technology.Charles Kemp of the Health Care Robotics Lab is the senior researcher for the project.In a test run, Cody was able to remove 96% of a test subject's dirt—not bad for a robot.But don't go asking for Cody for Cody yet—he's still a model.Yet researchers believe that one day Cody may take the place of nurses for this task.Researchers claim that Cody will afford patients increased private information.I suppose that would depend on the patient.Even so, I can appreciate the need.We don't have enough nurses to go around, and those places tha t are the most shorthanded, for example, nursing homes, are those that have the most patients who are unable to bathe themselves.Still, before I get there, I hope they think of a better way to solve the problem.11．The writer thinks bathing others must ________．A．bring you various health benefitsB．make you feel thankfulC．take you a lot of patienceD．make you feel dignified12．What is the third paragraph mainly about?A．Why and where Cody was designed.B．What Cody looks like and who designed it.C．What Cody can do and where it will work soon.D．How Cody works and what has made that possible.13．We know from the fourth and fifth paragraphs that ________．A．Cody can bathe patients better than a real nurseB．robots like Cody are being produced in large numbersC．Cody can take the place of nurses completely in hospitalsD．researchers think Cody can protect patients' personal information14．There is a need for Cody because ________．A．there are not enough nursesB．it can bring down the cost of nursingC．people are becoming lazierD．there are too many nursing homesBWhen one person gains weight, his close friends often follow.Researchers have just offered evidence in a study that says obesity(肥胖) appears to spread through social ties.But the findings might also offer hope.If_friends_help_make_obesity_acceptable,_then_they_might_also_be_influential_in _losing_the_fat.The researchers note that support groups are already an effective tool in dealing with other socially influenced problems, like alcoholism(酗酒)．The findings appeared in the New England Journal of Medicine.The researchers used information collected from 12，000 people.It was collected between 1972 and 2003 as part of the Framingham Heart Study.The information was highly detailed.There was even contact information for close friends of the people in the study.The researchers examined more than 40，000 social ties.They found that a person's chances of becoming severely overweight increased by 57% if a friend had become obese.A sister or brother of a person who became obese had a 40% increased chance of becoming obese.The risk for a wife or husband was a little less than that.Nicholas Christakis of Harvard Medical School was a lead researcher in the study.He says there is a direct causal relationship between a person getting fat and being followed in weight gain by a friend.The study found that the sex of the friends was also an influence.In sam esex friendship, a person had a 71% increased risk of becoming obese.Men had a 44% increased risk of becoming obese after weight gain in a brother.In sisters, it was 67%.The researchers also considered the effect of where people lived in relation to each other.James Fowler of the University of California was the other lead expert.He says a friend who lives a few hundred kilometres away has as much influence as one in the same neighbourhood.He says the study demonstrates the need to consider that a major part of people's health is tied to their social connections.Both researchers say their research shows that obesity is not just a private medical issue, but also a public health problem.15．What does the underlined sentence in Paragraph 2 mean?A．Obesity has a negative influence on close friends.B．Friends might also play a part in losing weight.C．One might have a positive influence on one's friend.D．Friendship may have little to do with one's health.16．Which of the following statements would Nicholas Christakis agree to?A．If one gains weight, one's friends are likely to get fat.B．Social problems like alcoholism are easy to deal with.C．Friends usually don't follow each other to lose weight.D．One might influence others on their social behaviour.17．James Fowler seems to believe that________ .A．a friend who lives nearby affects us mostB．one's health has nothing to do with friendsC．social connections have no effect on one's lifeD．a friend living far away has the same influence as one's neighbour18．The author makes his point clear in the text that________．A．a major part of people's health is based on their genesB．friends living closer have a greater influence on one's healthC．social relationship is closely connected with people's healthD．people's mental condition is subject to social connectionsⅢ.完成句子19．Owing to the guard's carelessness, the thief was lucky to

As like anything else you let your children do, you need to set limits. Drinking coffee whilesocializing once or twice a week will not cause a severe caffeine addiction. However, you should avoid allowing a cup of coffee every morning and ensure theyget adequate sleep each night, which will make them less likely to feel the needto drink coffee.As parents we have responsibility to set a good example. If you're addicted to caffeine, it's time to start monitoring your intake. If you drink much water and keep healthier drink options in your fridge and at your dinner table, your teenwill follow you. I drink much water and so do both my children.My_kids_learn_more_from_watching_me_do_things_than_they_will_ever_learn_from_my_ve rbal_teaching.As a mother, I'm ready to allow my child to try coffee, and we'll talk aboutit and discuss the pros and cons of consuming this. I feel open communication is vital in helping them make good decisions. Although, the decision to drink coffee doesn't pose the same dangers as underage drinking, it still deserves a thoughtful conversation.16．The author began to do research on coffee in order to ________．A．offer some good advice to coffee shopsB．guide her daughter to drink coffee properlyC．stop her daughter hanging out in coffee shopsD．let her daughter believe that fruit juice is healthy17．What might be the content of the plan the author would come up with?A．How her daughter can keep safe.B．Why coffee is as dangerous as alcohol.C．How her daughter can avoid caffeine addiction.D．What benefits her daughter can achieve from coffee.18．According to the text, if teens have enough sleep, they ________．A．will not ache for coffee that muchB．will not hang out in coffee shopsC．will not drink coffee for everD．will drink water instead of coffee19．What does the underlined sentence in the fourth paragraph imply?A．The author's children don't like to talk with her.B．The author thinks a good example functions better.C．The author is living in harmony with her children.D．The author doesn't want her children to learn from her.20．Which of the following statements agrees with the author's opinions in the text?A．Teens should stop from entering coffee shops.B．Coffee shops should not offer many options to teens.C．Teen's activities in coffee shops should be limited strictly.D．Parents should not force their children to stop drinking coffee.Ⅲ.读写任务阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

入舵市安恙阳光实验学校Unit 2 Healthy eatingⅠ.阅读理解ABiologist Robert Pitman and his colleagues tracked orcas，or killer whales，and humpback whales off the coast of Western Australia.To research further，the scientists attached a tracker to a female orca，which allowed them to use satellites to monitor her movements.They followed her for six days.During that time，the orca attacked eight young humpback whales.During the seven attacks，the orca killed the humpback whale calf (幼兽) on three occasions.But the story doesn't end there.Humpback whales themselves are popularly thought to be large but generally，passivecreatures.Pitman's study findings may let people think otherwise.When chased by orcas，humpback whales are known to try to outswim orcas.They are thought to do this at high speed so that the orcas can't keep up.On some occasions，the humpback whales sought out protection.They swam to shallow water，nearby reefs，or even under the researchers' boats.These ways often reduced the attack.But at other times，the humpback whales decided to stay and fight.As the orcas approached，the mother humpback would sometimes move her calf to her side，or lift it out of the water using her head or flippers.She also blew huge breaths of air to disturb the orcas，and lunged or charged at them，slashing(劈)and slapping her tail and flippers.Perhaps most surprisingly，humpback whales also have adult “escorts (护卫队)” that try to protect calves that are not their own，joining the mother in defending the smaller whale.These escort whales either charged at the orcas，or placed themselves between the attackers and calves，slashing their tails and flippers.Despite the efforts of the mother whales and escorts，the orcas were more often than not successful in their attacks.But the presence of the escorts did reduce how many times a whale calf was killed.[语篇解读] 本文是一篇说明文，主要讲的是科学家使用科学仪器来观察鲸是如何追杀驼背鲸及后者是如何反击和保护幼小的驼背鲸的。

Only one third of it was relevant to their work, the survey found. Information overload for whitecollar workers has become a global issue. The huge amount ofinformation has already affected their efficiency in management as well as their performance at work.Buried with emailsEvery morning, a secretary at the human resources department of an auto parts company opens her email box, only to find it crammed with at least 50 unread mails.For her, even scanning through these emails every day takes at least half an hour. Some of her colleagues are not so lucky—they have to read at least 100.Bothered with callsTelephone calls are also causing a problem. More than 40 percent whitecollar workers choose mobile phones as the preferred way to communicate important and urgent business matters. Talking saves time and energy over the clicking, reading and replying to emails, but phone calls are also more distracting(分心的). While answering a call, a clerk is likely to put away a much more important task at hand and start the business being talked about on the phone.Solution? Not yetMany companies start with providing staff with better computers, better Internet access and more advanced gadgets(小装置). For example, staff members above a certain level in one company will be provided with a blackberry phone for easier access to their emails. The company has also organized many lectures on efficient ways ofemail management. Yet most whitecollar workers think their companies can do more.16．What does the ne w survey find about whitecollar workers?A．They spend 51 percent of their work time on meetings.B．Only half of the information they receive is useful.C．Over 60 percent of them prefer to use the telephone.D．Some of them have to read at least 100 emails every day.17．Telephone calls cause a problem because ________．A．they take up the time to receive and send emailsB．they are often not answeredC．they are mostly not about businessD．they may lead to change of work schedule18．How do some companies try to solve the problem ofinformation overload?A．They start to give staff a pay rise.B．They plan to employ more people.C．They provide employees with more advanced equipment.D．They organize lectures on how to reduce stress.19．What is the major issue discussed in this text?A．Poor management leads to inefficiency at work.B．Junk mail is causing big trouble.C．Whitecollar workers suffer from information overload.D．Better computers are in need in workplaces.Ⅲ.[2013·绍兴一中分校高三期中]任务型阅读下面文章中有5处(第20～24题)需要添加小标题。

When my best friend went abroad, he sent me a book as a gift, which always reminded me of him (定语从句). Unfortunately, my book was gone after I came back from the school playground.You can't imagine how regretful I was to take the book there (宾语从句). I had planned to take it back after I played basketball. I searched everywhere for it, but without result. I sat in the classroom, feeling sad and wondering how I could do to get my lost book back (现在分词作伴随状语). Just at that moment, a boy in the next class came to me. When he was approaching me, I found there was something in his hand that I was familiar with. It was just my book. He told me he found the book when he took exercise on the playground and learned that it belonged to me. No one could tell how important it was to me (宾语从句)．I appreciate his kindness and consideration so much. I will learn from him and be a person who is always ready to help others.I still remember a day last term when I was in our school library.I lost my glasses, without_which_I_can't_see_anything (没有眼镜我什么也看不见，“介词＋which”引导的定语从句)．One rainy afternoon, I came to the school library, hoping to kill time.

The next day when I went back to the library, I found they were gone. I was very worried. My head teacher told me to put up a notice outside the lost and found office. My classmates also helped me and some of them even put up a notice on their backsreading_that_whoever_found_and_returned_the_glasses_would_receive_a_ special_gift (上面写着无论是谁发现并且归还了眼镜都将收到一份特殊的礼物，现在分词作后置定语). A short while later, a teacher in the office called me and told me the good news. I eventually found my “two windows”.

B．It is a bad habit.C．It is helpful. D．It is a waste of time.3．What is the main idea of this passage?A．Don’t be children’s drivers after school.B．Let children learn something from various subjects.C．Make your c hildren learn as much as possible.D．Choose activities for your children wisely.B(2013·安徽名校高三第二学期模拟考试) Slow parenting means parenting children in the contact of nature without any interference of materialistic influence.We can also term it as “selfraising”．In slow parenting children are allowed to do what they think proper and parents just keep a watch over the child.Curiosity of the child leads to exploring and discovering things.Parents provide little help only when it’s too necessary，otherwise keep themselves away from the child and just have a look on him/her.This brings about a feeling of selfdependency a nd they are encouraged to solve their problems.This is a natural way of learning.When a child is left to learn in a natural environment，the child’s natural development takes place.Influence of any materialistic way doesn’t let the mind develop naturally.W atching TV，playing video games or joining classes of dance，swimming or any other sports will not let the mind develop naturally.Here creativity of their mind is developed.They explore ideas.The logic behind this is that the kids of animals learn by nature，so can our kids.So let our children play in the garden，to watch flowers，plants，birds，butterflies and other gifts of nature.In the classes of dance，swimming etc.their creativity is influenced and their natural creativity is suppressed.In these classes they are overburdened and can’t enhance their creativity.So let them play in the open air or garden withont any burden instead of joining classes.Generally parents give toys to their children and explain how to operate them.But those parents who believe in slow parenting give toys and observe how the children are managing them.Their skill to learn and understand comes out.Maybe the process is slow，but it will be their exploration，which will make them selfdependent，and selfcapable to learn.4．In slow parenting，parents________.A．give the whole directions to what their children doB．keep a close watch over their childrenC．give their children freedom to do what they think properD．set limits to what their children do5．What is the main advantage of slow parenting according to the passage?A．Keeping children away from materialistic influence.B．Arousing children’s curiosity.C．Making children interested in exploring natureD．Helping children to be independent.6．We can infer from the third paragraph that________.A．exploring nature is a good way of slow parentingB．children can’t learn by nature like the kids of animalsC．slow parenting should be done in a logical wayD．children should join some classes7．The author believes joining various classes________.A．can train children’s ability of solving problemsB．is no good to children’s creativityC．is a necessary part of slow parentingD．also helps improve children’s creativity8．What is the passage mainly about?A．Different parenting styles.B．The requirements of slow parenting.C．Slow parenting and its advantages.D．The author’s attitude towards slow parenting.答案：课时作业(十二)Ⅰ.单项填空1．解析：考查情景对话。

At this point, of course, any pill for humans is but a twinkle(闪烁) in the eye of every medicine company's CEO.More tests are to be made, and eventually humans will be introduced in the test.But for now，unfortunately，control in diet is still the key.16．What does “such a surprising task” in Paragraph 4 refer to?A．Eating a lot of food while losing weight.B．Burning up fat very quickly.C．Controlling the diet.D．Having a rich fantasy life.17．In the experiment, the mice without those enzymes________.A．were in good conditionB．put on weightC．became weakD．could not have baby mice18．What does the author want to show through the last two paragraphs?A．You can be free of guilt when having big dinners.B．Scientists cannot find the key to identifying theenzyme.C．Don't overeat before the test is made on humans.D．It is unnecessary to control weight at present.BThese fast food restaurants constantly remind us of the American fondness with hamburgers，chips and pizza.But America's reputation as the home of fast food is under threat from the British，according to a research carried out by the BBC in 13 nations among 9,000 people.Despite fears over obesity，the study found the British are more obsessed with junk food than any other nation.Almost half of British respondents(参与调查者)said they enjoyed fast food too much to give it up. About 44 percent in the US claimed they would be unable to stop eating burgers，pizzas and chicken wings，making the country second in the world's junk food league. The third place went to the United Arab Emirates，where 35 percent are junk-food lovers.The research also found that attitudes to food and weight vary wildly around the world. Those in the UK and US believed lack of self-discipline was the main factor behind growing waistlines(腰围). They can't deny themselves that hamburger or extra piece of pizza，but “make themselves f eel better by washing it down with a diet coke”，the study suggested.The French，on the other hand，seem to keep a watchful eye on their weight. They get on the scales every day. Only 19 percent of the French surveyed admitted a fondness for fast food.Thierry Pailleux，of France，from the market research firm that conducted the poll，said the French valued the combination of good food and company. Sharing classic food and time with loved ones is key to the French sensibility. “French people take care of their image as a matter of course. Being thin is part of our culture and a point of pride. We are known for it，”said Pailleux.“On top of this，there is increasing awareness of the devastation(伤害)that obesity can cause to one's health.”19．What's the main idea of the passage?A．A study of different attitudes towards fast food.B．How popular fast food is in foreign countries.C．Different countries' attitudes towards food and body weight.D．A study of how popular fast food is in foreign countries.20．The research shows that ________.A．Americans are proud of the fast foods they eatB．those British who love fast foods do not care about their body weightC．the British would like to think that other foods they eat make up for eating occasional fast foodD．most Americans believe the enjoyment of food is more important than its possible effect on their waistlines21．What's the meaning of the underlined word “obsessed” in the second paragraph?A．Crazy. B．Obese. C．Opposed. D．Neutral.22．Why are，according to Thierry Pailleux，the French less obsessed with fast food than the British and Americans？Because ________.A．they value their imageB．they have better foods than other countriesC．they value self-disciplineD．they are afraid of having an unhealthy dietⅢ.短文改错假定英语课上老师要求同桌之间交换修改作文，请你修改你同桌写的以下作文。
