1、（14）Unit 3 Fit for life一、阅读理解1. We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to

2、 living at high altitudes. Cattle-raising people in East Africa and northern Europe have gained a mutation(突变) that helps them digest milk as adults. On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptationnot to air or to food, but to the ocean. A group o

3、f sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, theyve also built houses on stilts (支柱) in coas

4、tal waters. They are simply a stranger to the land, said Rodney C. Jubilado, a University of Hawaii researcher who studies the Bajau. Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. We were so a

5、mazed that they could stay underwater much longer than us local islanders, Dr. Jubilado said. I could see them actually walking under the sea. In 2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving coul

6、d have led to the evolution of physical characteristics that made the task easier for them. It seemed like the perfect chance for natural selection to act on a population, said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.1.What does the author want to

7、 tell us by the examples in Paragraph 1 ?A.Environmental adaptation of cattle raisers.B.New knowledge of human evolution.C.Recent findings of human origin.D.Significance of food selection.2.Where do the Bajau build their houses?A.In valleys.B.Near rivers.C.On the beach.D.Off the coast.3.Why was the

9、hods of Genetic ResearchD.The Worlds Best Divers2. Tom Macdonald would describe himself as pretty relaxed unless he sees the doctor. Then, suddenly, his blood pressure(血压) rises. I was a truck driver, and I would be under pressure all day, dealing with traffic and long journeys to make sure we were

10、on time, said Tom. But I never got worried about work. Yet medical settings made me very nervous. This wasnt a problem until last year when Tom developed an umbilical hernia (疝气). His doctor toldhim although it was not serious, if left untreated, a hernia can cause bad results. However, Toms situati

11、on created problems. When I had my blood pressure taken in hospital, the doctor told me that I wouldnt be able to have the surgery because it was so high. Surgery for patients with high blood pressure can be risky. But when Toms blood pressure was taken later, the top number fell to below 140 high,

12、but not high enough to prevent surgery. Soon afterwards, my doctor told me that I suffered from white coat syndrome(综合征). He explained it was seeing a doctor or being in a hospital that caused my blood pressure to rise even if it is usually normal. The main difficulty with white coat syndrome is tha

13、t it only happens in a medical setting, which means you cant really treat it, says Professor Peter Sever. You cant send a patient away with medicine because once he gets home and takes it, his blood pressure is going to fall through the floor. The good news is that many people do gain control over t

14、he syndrome; knowledge can make a difference. For some people, if they know they have it, they do seem to be able to take some control over it and it can improve, says Professor Sever. Many hospitals now have methods of solving the problem of white coat syndrome. They include the Will Adams NHS Trea

15、tment Centre in Gillingham, Kent, where Tom finally had his hernia repaired earlier this year.1.What caused Tom to get worried?A.Traffic jams.B.Long journeys.C.Medical settings.D.Heavy work.2.What prevented Tom having the surgery at first?A.His white coat syndrome.B.His doubt about his doctor.C.The

17、tisfying.C.Its unexpected.D.Its disappointing.3. We have a sweet teeth. That makes sense. All animals need sugar to live. Its the fuel that powers our cells. So its not surprising that were born to want the sweet stuff. Sugar stores energy like a battery. After a meal, your body breaks down foods. I

18、t uses some sugar for energy right away. The rest gets stored for the body to break down later. Its a myth that sugar makes you extremely excited, but having a sugary snack can give you a quick burst of energy. Thats because the sugar in sweet foods is easy for your body to turn into fuel. When you

19、eat other kinds of foods, like vegetables, it takes longer for your body to break the sugars down. These days its easy to find sweet snacks. Sodas, candies, cakes and even foods that seem healthy, such as yogurt, can be packed with sugar. Food makers add sugar, because they know that to humans, swee

20、t makes everything taste better. Americans eat about 20 teaspoons of extra sugar every day. Thats more than what is good for us. Eating too much sugar can cause more than a stomachache. It can make people overweight, decay the teeth and even cause diabetes. However, experts arent worried about natur

21、ally sweet foods the problem is added sugar. So go ahead and enjoy a sweet apple or even a sugar-rich carrot that is also full of vitamins and other good stuff. Even cake is great once in a while, as long as you dont overeat it. After all, no one wants life to be dull. And your body needs its fuel!1

24、ood?D.Why Does Sugar Make Us Fat?4. As early as 2005, there were a number of new stories about dog cloning and cat cloning. Animal cloning had been old news for nearly a decade by then, with the revolutionary(革命性的) cloning of Dolly the sheep in Scotland. However, Snuppy was the first pet, a dog, to

25、be cloned. Since the cloning of Snuppy, there has been some very successful cloning of pets and other animals. Lou Hawthorne started BioArts while cloning his beloved mixed-breed dog Missy. Hawthorne was very pleased with the results of the cloning, producing three successful clones that were very a

26、like to the original in character and behaviour. In January, 2009, a Florida couple, Ed and Nina Otto, announced that they had paid to have their dog cloned by BioArts. All new technology is overpriced. For example, personal computers were not very affordable at first. Only after the producing proce

27、ss was improved was it possible for every family to have a computer. How much room there will be for organizations to reduce the price point on pet cloning without broad demand is of course questionable. There are many great dogs and cats that can be found at the local pound(收容所) or are given away f

28、or free to good homes in classified ads(分类广告). However, there is no limit to the value people place on a beloved pet. The Ottos are a good example of that. If people can buy a dog or cat with predictable behaviour and characteristics, there is value in that. There is a predictable market here, thoug

29、h it may always be limited in size. While pet cloning has not taken off as some hoped, its clear that it will become a bigger market in the future and it will be increasingly possible for people to try this out. With the inevitable(不可避免的) success that cloned pet owners will have, the practice will b

If you are fighting anxiety in your life, here are some tips on dealing with depression naturally. Try therapy._ There is no harm in asking for help and it is

33、never too late to do that. Professional help will always be better. The main reason is that an expert therapist is capable of dealing with the condition. Eat healthy foods.
