1、单元检测卷 Unit 1第一部分： 阅读理解 （共两节，满分 40 分）第一节 （共 15 小题；每小题 2 分，满分 30 分）AIf you think that running marathons will help you live a long and healthy life, new research may come 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
2、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
3、 speed to jog at is 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 an
4、d 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
5、 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, “Y
6、ou dont actually have to do that much to have a good impact on your health. And perhaps you shouldnt actually do too much”.1.

8、nsumes 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 healthBChristopher Thomas, 27, was a writer by night and a teacher by day when
9、 he noticed he was always tired and was losing weight fast. Diagnosed with diabetes(糖尿病), Thomas would need to inject himself with insulin three times a day for the rest of his life or risk nerve damage, blindness and even death. And if that werent bad enough, he had no health insurance.After a mont
10、h of feeling upset, Thomas decided hed better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created diabeticrockstar. com, a free online community for diabetics and their loved onesa place where over 1100 peopl
11、e shared personal stories, information and resources.Jason Swenckis son, Kody, was diagnosed with diabetes at six. Father and son visit the online childrens forums (论坛) together most evenings. “Kody gets so excited, writing to kids from all over,” says Swencki, one of the sites volunteers. “They kno
12、w what hes going through, so he doesnt feel lonely.”Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.These days, Thomass main focus is his charity (慈善机构)，Fight It,
13、 which provides medicines and supplies to people 225 to datewho cant afford a diabetics huge expenses. Fight-it. org has raised $23,000 in products and in cash.

17、dical website.CHappy birthday! Do birthdays really make people happy? Of course they do. Birthdays celebrate the day we were born. Besides, that extra candle on the cake suggests another year of growth and maturityor so we hope. We all like to imagine that were getting wiser and not just older. Most
18、 of us enjoy seeing the miracle of growth in others, as well. For instance, seeing our children develop and learn new things makes us feel proud. For Americans, like people in most cultures, growing up is a wonderful process. But growing old? Thats a different story.Growing old is not exactly pleasa
19、nt for people in youth-oriented American culture. Most Americans like to look young, act young and feel young. As the old saying goes, “Youre as young as you feel.” Older people joke about how many years young they are, rather than how many years old. People in some countries value the aged as a sou
20、rce of experience and wisdom. But Americans seem to favor those who are young, or at least “young at heart”.Many older Americans find the “golden years” to be anything but golden. Economically, “senior citizens” often struggle just to get by. Retirement at age 65 brings a sharp decrease in personal
21、income. Social security benefits usually cannot make up the difference. Older people may suffer from poor nutrition, medical care and housing. Some even experience age discrimination (歧视). In 1987, American sociologist Pat Moore dressed up like an older person and wandered city streets. She was ofte
22、n treated rudelyeven cheated and robbed. However, dressed as a young person, she received much more respect.Unfortunately, the elderly population in America is increasingly fast. Why? People are living together. Fewer babies are being born. And middle-aged “baby boomers” are rapidly entering the gro
23、ups of the elderly. America may soon be a place where wrinkles (皱纹 ) are “in”. Marketing experts are already noticing this group of consumers (消费者).8.

24、 C. the old in America have to retire at the age of 65D. American social security benefits are not good9. From the last paragraph we know that the underlined word “in” can be replaced by_. A. serious B. bad C. disappearing slowly D. growing fast10. From this passage we can know_. A. in America, grow
25、ing up is not a wonderful process B. in America, growing up is as wonderful a process as growing old C. in America, growing up is a wonderful process, while growing old is not D. in America, growing old is a wonderful process, while growing up is not11. What should be mentioned in the following para
26、graph?A. The public will change their attitude towards old people.B. People will provide more services to the old in their communities.C. Companies will soon produce more goods for old Americans. D. The government will pass laws to ensure the benefits of the people.DTo many web-building spiders, mos
27、t of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey (猎物), meeting mates and protecting themselves. A web-building spider without its web is like a man cast away on an island of solid rock, totally out of touch and destined to starv
28、e to death. So important is the web to an orb-web spiders survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier (憔悴的), it constructs a wider-meshed web using fe
29、wer strands (线). Such webs would only trap larger prey, which is more economical from the perspective of a starving spider. The spider stores energy by recycling web protein. It simply eats its own web each evening and re-uses it to produce new silk. In studies with radioactively labeled materials,
30、it was found that 95 percent of web protein reappears in the next days web. Most of the energy needed for web-building is used in walking over the strands as they are laid down. Scientists are impressed by the adaptability（适应能力） of the spiders highly preprogrammed brain, which is larger for its size
31、 than the brain of any other invertebrate (无脊椎动物). If web-building is interrupted, or if some of the existing strands are destroyed, the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will even finish building the incomplete web of anothe
