——————————教育资源共享步入知识海洋————————Unit 2 Healthy eating李仕才一、阅读理解AA new study has found the amount of antibiotics (抗生素) given to farm animals is expected to increase by twothirds over the next 15 years. Researchers are linking the growing dependence on the drugs to the increasing need for meat, milk and eggs. However, the drugs could quicken the development of antibioticresistant infections (感染). Such infections are already a major public health concern in the United States.The World Health Organization(WHO) notes when people stop living in poverty(贫困), the first thing they want to do is eat better, rather than earn more money. For most people, that means their diet should contain more meat. With the rapid development of Asia, people there are eating nearly four times as much meat, milk and other milk products as they did 50 years ago.To meet the need, farmers have put many animals into smaller spaces. As the animals are crowded together, the easiest way to deal with some of the problems of crowding is to give them antibiotics. It's clear that antibiotics help animals stay healthy in crowded environments and grow faster. But bacteria can develop resistance to the drugs gradually.Nowadays, doctors find antibiotics that once worked against the infections no longer work. The bacteria have learned ways to fight against the drugs. The heavy use of antibiotics in farm animals is responsible for the growth of antibiotic resistance worldwide. Each year in the United States, at least two million people get antibioticresistant infections and at least 23,000 die from these infections.Europe has banned the use of antibiotics to increase animal growth. And the United States is hoping to persuade farmers to stop using antibiotics for that purpose.【文章大意】本文主要围绕在农场动物身上使用抗生素的负面影响展开。

Unit 2 Healthy eatingⅠ.阅读理解A(2020·东北三省四市高考模拟) Until last year，Borris would never turn down a pork steak.By the time his owner，Annemarie Formoy，entered him in the PDSA Pet Fit Club petition，he was 28kg—almost double his remended weight.Thanks to a tailored sixmonth diet and exercise，he is now 7kg lighter.Borris，at his heaviest，was not alone.The worldwide rate of pet obesity(肥胖症) lies between 22% and 44%.The reasons are fairly predictable.Owners of overweight dogs feed them more snacks and table leftovers，are more likely to have their pets present as they prepare their own meals and are less likely to walk them daily.Owners of obese cats tend to use food as a reward and play with them less.But obesity also seems to be occurring even in some wild animals that aren't being overfed or underexercised.If these findings are true，something else must be driving obesity and uncovering those could help solve our own problems with the condition.“Labradors are consistently the headline act when it es to overweight dogs，”says Eleanor Raffan，a veterinarian and geneticist.She and fellow researchers discovered that a genetic mutation(基因变异) present in around a quarter of Labradors was associated with obesity.For each copy of the mutation—which occurred in a gene called POMC—a dog was about 2kg heavier.Most of the animals the researchers studied had one copy of the mutation，but fewer had two.“These are dogs always in the kitchen when owners are preparing food，sticking around scouring_a_titbit even if there's not much chance of getting food，or eating disgusting stuff on walks，” Raffan says.“But they're not doing that because it's fun.They're doing it because they're hungry.”That's because POMC mutations disturb the brain's function of controlling food intake and energy consumption.As a result，the behaviour of these Labradors beesvery foodmotivated.语篇解读全球宠物肥胖率在22%到44%之间，弄清楚宠物肥胖的原因对人类应对肥胖问题也很有启发。

You can send a letter or pick up thephone and make a call.But today, one of the most popularways to communicate is called Instant Messaging (IM). Inany instant messaging system, you type a little text message on your computer, press the “Send” button, and your message instantly shows up on your friend's screen.But how does it work?Actually, the whole process is very cool.In the 1980s, you could sit down at a computer at any big university.Up to 100 people would be logged in and share the computers because these computers were very expensive. You could type a command to send an instant message to anyone logged in the same computer. It felt like everyone was connected together no matter where they were sitting.Today, you can communicate with anyone in the world. All you need is an instant messaging program installed on your computer.There are many programs to choose from.AOL's instant messenger is probably the most popular right now.MSN has one.Google has Google Talk.When you're ready, you create an account.Next, you need to figure out the IM names your friends use.Add their IM names to your IM program.Click on the friend you want to talk to and then type away.When you click“Send”， your friend gets the message instantly.But behind the scenes, amazing things are happening.Your IM program is communicating with a computer, called a server, which could be just down the road or even in some other cities.All your friends' computers are communicating with a server, too.Your computer is constantly chatting with it to make everything happen.The network called the Internet makes it all possible.1．What could be the best title of the passage?A．Different Ways of CommunicationB．The Easiest Way to Talk to a FriendC．How to Send Instant MessagesD．Development of Communication【解析】标题归纳题。

One current challenge to opera is economics. The shortage of money raises the broader question of how much should be paid to support opera singers and other artists. Society seems to accept the large salaries paid to business managers and the multimilliondollar contracts given to sports athletes. But what about opera singers? Somehow, people have the idea that artists can be creative only if they suffer in poverty, but this is unrealistic. If artists, including opera singers, lack the support they need, valuable talent is wasted.Another problem faced by opera is how to meet the demands of audiences who are influenced by popular entertainment. Pop singers are often judged as much on the basis of how they look as how they sound. These demands may be unrealistic and possibly harmful. Opera singers simply cannot make a sound big enough to fill a large theater or concert hall without a microphone if their body weight is too low. Emphasizing physical appearance over singingability may cause audiences to miss out on the human voice at its best.There are no easy solutions to opera’s problems and there are many different opinions about the value of opera. However, every year many young people register for music courses with hopes and dreams of developing their talent in this special art form. The fact that opera has survived many obstacles and continues to attract the rising generation shows that it remains a respectable art formfull of value.【解题导语】本文主要讨论了歌剧所面临的挑战和困难. 1．Which of the statements is TRUE according to the passage?A．Opera singers’ life stories are dramatic.B．Opera will soon appear on TV and in films.C．Opera fans thank celebrities for performing.D．Opera develops by adapting to new conditions.D 解析：推理判断题.根据第一段中的“Over the years, it has responded to various musicals.”可推知，歌剧适应新的状况而得以发展，故选D.2．What can we know from Paragraphs 2 and 3?A．Opera singers are financially insecure.B．Opera singers waste their valuable talent.C．Opera singers get paid before the show.D．Opera singers perform better if they are poor.A 解析：细节理解题.根据第二段中的第二句以及第三段第一句可知，歌剧演唱家的经济是有问题的，不稳定的，故选A.3．What does the author try to say in Paragraph 4?A．Popular culture has had a positive influence on opera. B．Audiences know best how opera should be performed. C．Microphones should be used to make opera more enjoyable. D．Opera singers’ voices should be valued more than theirlooks.D 解析：推理判断题.根据第四段最后一句可知，歌剧演唱家的声音要比外貌重要得多，故选D.4．What would be the best title for this passage?A．The Economic Challenge to OperaB．Opera Faced with the DifficultiesC．Opera as Part of Popular CultureD．The Historical Context of OperaB 解析：标题归纳题.根据最后一段第一句并结合全文的整体内容可知，本文主要讨论的是歌剧所面临的问题和挑战，故选B.二、单句语法填空1．If you don’t want to put on weight, you should cut on the amount of foods rich in sugar and fat.答案：down答案：balanced3．Having realized that your time is (limit), you willhave to study for your goals without anger and hesitation.答案：limited4．—How was your interview for going abroad to study?—Oh，I couldn’t feel any (bad)．I hardly understoodmost of the questions they asked.答案：worse5．—In this day and age, women can have children and jobsas well.—I can’t agree more.

Unit 2《Healthy eating》单元检测卷：Unit 2阅读理解AIf you think that running marathons will help you live a long and healthy life, new research may e as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all. Scientists in Denmark have been studying over 1，000 joggers (慢跑者)and non-joggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious injuries. Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy(寿命), jogging a few times a week at a moderate (适度的)pace is a good strategy. Anything more is not just unnecessary, and it may be harmful.”The implications (暗示)of this are that moderate forms of exercise such as tai chi, yoga and brisk (轻快的)walking may be better for us than “iron man”events, triathlons and long-distance running and cycling. According to Jacob Louis Marott,another researcher involved in the study, “You don’t actually have to do that much to have a good impact on your health. And perhaps you shouldn’t actually do too much”.1. The underlined word “strenuous”in Paragraph 1 is closest in meaning to “_____________”.A. hardB. regularC. practicalD. flexible2. The author presents some figures in Paragraph 2 to __________.A. suggest giving up joggingB. show risks of doing sportsC. provide supportive evidenceD. introduce the research process3. According to the scientists, why is too much exercise harmful?A. It may injure the heart and arteriesB. It can make the body tired outC. It will bring much pressureD. It consumes too much energy4. What can be inferred from the next?A. No exercise at all is the best choiceB. More exercise means a healthier lifeC. Marathons runners are least likely to dieD. Proper exercise contributes to good healthBWhen my friend Lesa was diagnosed(诊断) with cancer, another friend and I went to the hospital to spend some time with her. We bought her a small toy and named him Lemon－Aide. We gave Lemon－Aide to Lesa and told her he was to go with her to all of her treatments to remind her that we were thinking of herand caring about her even though we could not always be with her. When the treatments were pleted, she said when someone else needed him she would pass him along.A few months later，much to my surprise, it was me that she passed him to. Lemon－Aide went with me to all of my treatments.One day while waiting for my doctor I decided we could market the idea to fight cancer. Lesa thought it was a great idea so we founded the organization that came to be known as Lemon－Aide' s Friends, Inc. We designed our organization to remind people fighting cancer that there are people who love and care about them all the time. Today we have totally 5013 volunteers. The money raised is donated to cancer patients who do not have insurance. The Physicians on our Board of Advisors determine how and where our money is donated.Lemon－Aide is for men, women, and children of all ages and to date has been sent to 34 states and 33 countries to provide smiling support for people fighting cancer. When life gave us lemons we made lemonade. Lemon－Aide, a soft smiling toy that represents love, support, and encouragement.5．The author went to the hospital with her friend ________．A．to operate on Lesa B．to treat her diseaseC．to acpany Lesa D．to look after Lemon－Aide6．Lesa was given a small toy because ________．A．he represented her organizationB．he could help weaken her painC．she would think of her friendsD．her friends tried to fort her7．It can be inferred that ________．A．the author had suffered from cancerB．Lemon－Aide had suffered from cancerC．Lesa had recovered from cancerD．Lemon－Aide learned to look after the author8．Lesa and the author formed an organization to ________．A．cure cancer B．raise moneyC．help cancer patients D．help their friendCPeople are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals(间隔) each day.Low-calorie Diets Do Not WorkThe reason people cannot lose weight by starving themselves is that their metabolism (新陈代谢) will detect any major drop in calories and it will then adjust itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2,500 caloriesper day and not gain any weight.Low-fat Diets Do Not WorkMany people in today’s society are buying mostly low-fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle.Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.9. What is the main reason why people are overweight?A. They burn many calories every day.B. They eat the wrong foods at the wrong time.C. They eat food with lots of calories.D. They don’t take weight loss pills.10. The article is written in order to________.A. tell readers not to buy low-fat or non-fat food.B.tell readers about an important scientific discovery.C .tell readers how to lose weight.D. call on people to lose weight and stay healthy.11. T o realize the aim of your weight loss plan, you should_________.a. do exercise every dayb. eat meals at the right timec. eat fruits and vegetablesd. eat low-fat or sweet foode. eat the proper foods at each mealA. a, b, c, eB. a, b, d, eC. a, c, d, eD.a, b, c, dDHealth experts have long known that vitamin D is important for healthy bones and teeth. It may also help to protect the body against diseases such as diabetes(糖尿病) and cancer. And now, researchers say vitamin D might help fight brain diseases called dementia (痴呆).Dementia is a brain disease that damages thinking and memory processes, which scientists call “cognitive (认知) abilities.”Dementia is difficult to treat. T aking care of someone who has dementia is extremely demanding. And the disease is very frightening to sufferers. Chris Roberts suffers from dementia. He says the worst part of living with this disease was getting lost while driving. “The worst thing that I found was getting lost in the car, not just forgetting where I was going —I wouldn’t know where I was.”More than 47 million people around the world suffer from dementia. The World Health Organization reports that 60 percent of them live in low- and middle-ine countries.We get vitamin D from some foods like nuts, lentils (扁豆) and fatty fish. We also get vitamin D from the sun. But that is not dependable. In some parts of the world, there is not enough sunlight to provide enough vitamin D. Also, sunblock prevents the vitamin from entering the body. To add to the problem, the skin’s ability to process vitamin D weakens as a person ages.Researchers at Rutgers University in New Jersey are exploring the relationshipbetween vitamin D and dementia. The team recently measured vitamin D levels and cognitive ability in older people. Nutritional sciences professor Joshua Miller led the team.

So，when someone talks，keep yourself quiet and listen to them，especially if they’re feeling down，you need to be the shoulder for them to cry on. If you have any ment to make，be sure that you word it in a way where you don’t sound too negative. 17 When you just don’t share the same interest or you’re not in the mood to listen to them，politely let them know and ask them to understand.Always smile.18 The least you can do is，whenever you see your friends，smile and say hello. That way，if they had a bad day，you can make them feel better with your smile along with your ear，and maybe，you can share something funny to cheer them up. Don’t ever lie.Everyone would hate being lied to，especially if it’s by your own friend，so don’t lie！It might seem alright to lie occasionally，but once you lose your friend’s trust，you may lose them forever. 19Keep secrets.Make sure you can keep a secret. If not，tell your friends straight away you cannot help yourself when it es to secrets. Otherwise，when you let them tell you about their secrets and you “accidentally”share it with someone else，you’ll have your friends hating you for the rest of your life. 20 Secrets are not meant to be shared，so don’t even try.A．Everyone has their bad days，and it’s unavoidable.B．And that is something you surely do not want to happen.C．Well，you’ve e to the right place.D．A few people seem upset at you for being so direct.E．Otherwise，they may just take it as you are trying to put them down. F．This same thing happened to a good friend of mine.G．They’ll probably call you “big mouth”．完型填空Every person needs water and a diet of healthy foods.

The latest research indicates that men's hearts going into a rapid decline when they reach middle age could be the cause.The research of ageing on the heart has shown that women's longevity may be linked to the fact that their hearts do not lose much pumping power with age.“We have found that the power of the male heart falls by 20 percent—25 percent between 20 and 70 years of age,” said the head of th e study, Samantha of Liverpool John Moores University in the UK.“Within the heart there are millions of cells which make it beat. Between the ages of 20 and 70, one-third of those cells die and are not replaced in men, ”said Samantha. “This is part of the ageing process.”What amazes scientists is that the female heart suffers very little loss of these cells. A healthy 70-year-old woman's heart could work almost as perfectly as a 20-year-old one's.“This gender(性别)difference might give the reason why men live shorter than women. ” said Samantha. They studied over 250 healthy men and women between the ages of 17 and 80, who are mainly healthy persons so as to reduce the influence of disease. “The team has yet to think about why ageing suffers a great er loss on the male heart. ”said Samantha.But there is also good news—men can enjoy the health of their hearts with regular exercise. Samantha stressed that women should also take regular exercise to stop their leg muscles getting weaker as they age.1.Th e underlined word “longevity” in the second paragraph means “______”.A.healthB.long lifeC.ageingD.effect2.The text mainly talks about______.A.men's heart cellsB.women's ageing processC.the gender differenceD.hearts and long life3.According to the text, the UK scientists have known that_____.A.men have fewer cells than women when they are bornB.women can produce the cells that make the heart beatC.the female heart suffers less loss of the cells with ageD.women will never suffer the loss of pumping power with age4.If you want to live a long life, you should______.A.enable your heart to beat much fasterB.think about the reason for ageingC.take regular exercise to keep your heart healthyD.stop your cells from being lostWhile it is impossible to live pletely free of stress, it is possible to prevent stress as well as reduce its effect when it can't be avoided. 5 Try physical activity.6 Running, walking, playing tennis, and working in your garden are just some of the activities you might try.Make time for yourself.Schedule time for both work and entertainment. Don't forget, play can be just as important to your overall well-being as work. 7 Go window-shopping or work on a hobby. Allow yourself at least a half hour each day to do something you enjoy.Take care of yourself.8 If you easily get angry and can't sleep well enough, or if you are not eating properly, it will be more likely that you will fall into stressful situations. If stress repeatedly keeps you from sleeping, you should consult a doctor.9Stress can result from disorganization and a feeling that “there's so much to do, and not enough time”. Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything. Instead, make a list of everything you have to do, then do one thing at a time, checking off each task as it is pleted.
