1、届高考英语阅读冲刺练习之说明文十六高考英语阅读冲刺练习之说明文（A）Its a typical morning: you wake up, take a shower, brush your teeth, and then prick(刺)your arm with a tiny needle. Wait, what? Unless you have a serious disease such as diabetes,you probably havent ever tested your own blood. But in the future, that might change.The

2、 company Cor already sells a system for home blood testing. You stick your arm using a supposedly painless cartridge. Then you stick the cartridge into a device that looks like the base for an electric toothbrush. A few minutes later, an app on your phone offers you updated information, including yo

3、ur current health status and tips on what to eat and how to exercise.Its true that blood provides abundant information about a persons health. Specific tests can reveal if a person is infected with a disease or at risk for a variety of problems. But most people dont test their own blood often. Healt

4、hy young adults get blood tests approximately every five years. Cor and similar companies are trying to change the situation. They think people deserve access to more information about their health.But not everyone is convinced.The best-case scenario(情景)here is that you lose much money and then your

5、e reminded to get more sleep and to eat more fruits, vegetables and fish,Pieter Cohen of Harvard Medical School told The New York Times. Plus, the results of a home blood test might be wrong. Its hard to get accurate results from a tiny amount of blood. One company, Theranos, said it could perform m

6、edical blood tests on a fingerpricks worth of blood.But the company was soon stuck in a controversy(争议)and accused of cheating because its technology didnt work as promised. Thus, theres still a long way to go before the technology becomes advanced.1. Whats the function of Paragraph 1?A. To express

7、feelings. B. To raise a question.C. To make a prediction. D. To introduce the topic.2. What does the underlined word cartridge probably mean?A. Container. B. Operation. C. Medicine. D. Scan.3.Why does Cor promote home blood testing?A. To collect peoples health information. B. To offer people proper

8、suggestions.C. To help people track their health. D. To cure people of blood diseases.4. What is the authors attitude towards home blood testing?A. Ambiguous. B. Objective. C. Supportive. D. Uncaring.（B）For animals that spend most of their lives in the high trees, gaps in the forest might as well be

9、 the Grand Canyon. These gaps are especially hard on gibbons(长臂猴); although larger males can leap across some gaps, females and the young can be cut off from food, companions, and even potential mates. Now, a new study suggests a couple of strong ropes could really help bridge the gap.Gibbons are at

10、 risk of extinction across Southeast Asia, largely because of habitat loss. With about 30 individuals left, the Hainan gibbon is considered the rarest primate(灵长类) on Earth. All of these animals live on the Hainan Bawangling National Nature Reserve. In July2014, a typhoon caused landslides across th

11、e reserve, creating gaps in the forest that were difficult for these primates to cross.To help reconnect the habitats, professional tree climbers set up an artificial bridgemade of two mountaineering-grade ropes across a 15-meter-wide valley. Nearly 6 months later,the gibbons started to use the brid

12、ge to cross the gap, researchers report today in Scientific Reports. The team documented 52 crossings of a group of eight gibbons, with most walking along one rope while holding on to the second rope for support,which the scientists namedhandrail. The gibbons also shimmied underneath the ropes using

13、 all arms and legs to the opposite side.Conservationists previously built artificial bridges to help other species such as the Bornean orangutan and the Javan slow loris. But this is the first example of the rare Hainan gibbon using them. The rope bridges could be a short-term solution to reconnect

14、disjointed(脱节的)habitats, the researchers argue.1. What do we know about gibbons from the second paragraph?A. Rarely are gibbons seen for the population decline.B. Habitat loss was to blame for gibbons dying out.C. Gibbons couldnt cross gaps caused by a typhoon.D. The natural disaster may have posed

15、a threat to gibbons.2. What does the underlined shimmied likely mean?A. Lifted. B. Grabbed. C. Swung. D. Spread.3. What is the text mainly about?A. The reasons for gibbons dying out. B. The importance of saving gibbons.C. The measures to save gibbons. D. The solution to gibbons habitat loss.（C）Decad

16、es ago, NASA asked experts to develop the smell of space in order to help prepare astronauts for the experience of outer space. Now, a perfume, Eau de Space, has attracted eager buyers.According to the Kickstarter activity, which has been launched to sell Eau de Space, the history of the smell of sp

17、ace has been unclear owing to various accounts of its development.Ever since the first spacewalk, astronauts have been shocked by the smell.NASA astronaut Col. Chris Hadfield said,The only time you can smell space is when you come back from a spacewalk. As you open the hatch(舱门),there is a distincti

18、ve smell.Some astronauts and space tourists describe it as the smell of fruit, or burnt cookies. Astronaut Eugene Cerman talked of another smell he experienced:The moon smells like spent gunpowder.The smell of space is so distinet that NASA reached out to fragrance makers to recreate the smell, acco

19、rding to NASA documents.Now, the makers have cooperated with award-winning perfumers(香水制造者),and reported that theyve secured commercial contracts to reproduce the smell based on astronauts accounts.At $ 29 per bottle, Eau de Space will help support STEM (Science, Technology, Engineering and Math) pr

20、ograms for students. For every bottle of Eau de Space you buy,were going to donate $ 1 to a STEM program for low-income students. Its a big promise and isnt the best decision for a company trying to make a profit. But, imagine that a child who smells Eau de Space today is whipped up to become an ast

21、ronaut, scientist or engineer, shows Kickstarter.Eau de Space will be made in the UK employing low-income labor and environment-friendly practices, including zero manufacturing waste, according to the campaign. So far,about 11,000 people have become supporters.1. Why was the Kickstarter campaign sta

Astronauts Different Accounts About the Space Smell（D） Scientist at University College London have discovered sets of regulatory genes, which are responsible for maintaining healthy hearing. The finding, made in fruit fli

25、es, could lead to treatments for age-related hearing loss (ARHL) in humans.Globally, one-third of people aged over 65 experience hearing impairment, and while there are thought to be more than 150 genes that may affect hearing loss, there is no unified (统一的) view on how to use these to develop heari

26、ng loss treatments.In the study, published in Scientific Reports, researchers are at the UCL Ear Institute assessed the hearing ability of the common fruit fly across its life span (around 70 days) to see if their hearing declines with age.A fruit flys ears share many molecular (分子的) similarities wi

27、th the ears of humans, making it an ideal tool for the study of human hearing loss.Researchers found that the antennal ears of fruit flies also display ARHL with nearly all sensitive hearing measures starting to decline after 50 days of age. This made the researchers want to know if there were any “

28、age-variable” genes in the flies inner ears which have kept the ears healthy for 50 days of their lives.After closer examination, researchers identified a new set of regulatory genes-homeostasis genes. These genes are often responsible for picking up sound and the overall sensitivity of the ear. Usi

29、ng this information, scientists were then able to genetically modify (修改) the genes and prevent the flies from getting ARHL.Professor Joerg Albert, lead author of the study, said: “While many studies have been conducted into the hearing function of fruit flies, ours is the first to look at the mecha

30、nistic and molecular detail of their auditory life course.”“The fact that these genes are conserved in humans will also help to focus future clinical research in humans and thereby accelerate the discovery of new pharmacological or gene-therapeutic strategies.”1What did scientists at UCL discover?AO

31、ne-third of people aged over 65 have hearing problems.BHomeostasis genes maintain ones ability to hear.CThere are regulatory genes that are related to aging.DHumans have over 150 genes that can affect hearing loss.2Why were fruit flies used in the research?ATheir hearing system is similar to that of

32、 humans.BTheir hearing ability also declines with age.CThey display ARHL during their lifespan.DThey share many genes with humans.3What is the main purpose of the last two paragraphs?AThe discovery of new treatments. BThe significance of the study.CThe result of the study. DThe future commercial prospects.4Which of the following would be the best title for the text?AAge-related hearing loss: fruit flies and humansBHearing loss: a common problem for older adult
