1、What, or rather who, kills New Yorkers especially seniors and children as they cross the street? Drivers who speed, and drivers who dont pay attention. Five-year worth of New York crash data shows that “dangerous driver choices are the contributing factor in 70% of pedestrian deaths,” the city repor

2、ted this week. And in 53 percent of pedestrian deaths, the pedestrians were following all the rules crossing on a crosswalk with the light, for example, or sometimes just standing on the sidewalk. But a driver who was inattentive or speeding or who failed to yield （给让路） hit and killed them anyway. T

3、he biggest step that the mayor correctly put forward on Tuesday, then, was to lower and enforce （实施） speed limits. The hard part, though, will be enforcement. Police officers can write speeding tickets, and have been doing so. But ticket-writing consumes officers attention. A speeder may face an off

4、icer in one block but not the next. Thats why the mayor also wants Albany to allow the city to put in place more speed cameras than the 20 New York already has. In this way police resources （警力） will be able to focus on other dangerous behaviors, including truck drivers who come into the city withou

5、t enough mirrors and drivers who talk on cell phones or text. The most important factor in saving lives, though, is a changing culture which, in turn, is affecting political （政治的） will. The car and truck once ruled the road, and people, even in crowded city environments, were supposed to get out of

6、drivers way. Now, more and more people are walking or bicycling （often before or after a subway or bus ride）. New Yorkers expect to be able to raise children here or grow old here safely, even if that means a small number of drivers must do so more patiently.21. Facing the data of traffic deaths, Ma

7、yor Bill _.A. felt regretB. had his doubts C. seemed confusedD. sounded surprised22. What can be inferred from the city report?A. Drivers made dangerous choices on purpose. B. Obeying traffic rules would ensure your safety.C. Some drivers made a contribution to traffic safety.D. Some pedestrians wer

8、e partly to blame for their deaths.23. Among the following enforcement measures of speed limits, the mayor disapproves of _.A. educatingB. ticket-writing C. speed camerasD. police resources24. Which of the following can be considered to be a sign of the changing culture?A. Motor vehicles are disappe

9、aring. B. More people are walking or bicycling.C. City environments are getting more livable.D. New Yorkers are paying more attention to education. BBlue-eyed people have been living in Europe for at least 7,000 years, scientists have discovered.A man who lived on the Iberian Peninsula before Europe

10、ans became farmers probably had blue eyes but dark hair and skin, according to scientists who have sequenced （排序） his DNA. This surprising combination of eye, hair and skin coloring may not have been unusual during his lifetime, but it is no longer seen among modern Europeans, the team reported Sund

11、ay in the journal Nature. The man, a Neolithic hunter-gatherer known to scientists as La Braa 1, is of great interest to scientists because he offers a photograph of what was in Europeans DNA before agriculture （农业） spread through the continent. Experts have understood that certain genetic （基因的） fea

12、tures spread quickly among humans after they led the farming lifestyle. La Braa 1 shows that at least some of their expectations were correct.The mans skeleton, along with that of a male companion, was discovered in 2006 in a cave in what is now northeastern Spain. The site, known as La Braa-Arinter

13、o, sits about 5,000 feet above sea level, and the cave provided a cold, refrigerator-like environment that preserved his DNA.In the lab, scientists were able to take out enough DNA from a single tooth to reconstruct La Braa 1s entire genome （基因组）. They compared it to the DNA of other ancient Europea

14、ns and determined that he was a closer match with hunter-gatherers than with farmers.When it came to genes that would influence La Braa 1s appearance, the researchers found that their 7,000-year-old subject had versions of two skin pigment （色素） genes that are either very rare or nonexistent among Eu

15、ropeans today. Then they looked at other places in the genome that influence pigmentation and found a mix of ancient and modern gene variants （变体）. Taken together, La Braa 1s DNA “is likely to have resulted in dark skin pigmentation and dark or brown hair,” they wrote.However, his DNA indicates that

16、 his eyes were most likely blue, the scientists found. This suggests that gene variants for light-colored eyes and skin did not spread together, they wrote, adding that La Braa 1s combination “of dark skin and non-brown eyes is unique and no longer present in contemporary European populations.” Toda

17、y, a blue-eyed person would usually have fair skin.To get some idea of whether La Braa 1s coloring was unusual for his day, the researchers will try to sequence the DNA of his companion, who has been named La Braa 2.25. Why scientists are interested in La Braa 1?A. They can know Europeans DNA.B. The

18、y can know European hunter-gatherers DNA.C. They can know the ancient agriculture in Europe. D. They can know some of their expectations were correct.26. La Braa 1 was well preserved due to _.A. dry weatherB. a high cave C. proper protectionD. cold conditions27. Which of the following is TRUE accord

19、ing to the passage?A. La Braa 1s DNA influenced his appearance.B. La Braa 1s appearance influenced contemporary Europeans. C. La Braa 1s gene variants spread together.D. La Braa 1s genes are completely different from contemporary Europeans.28. The last paragraph suggests that _.a 2 has the same geno

20、me with La Braa 1B. Blue-eyed people were common in Europe 7,000 years agoC. Braa 1s combination of dark skin and non-brown eyes is uniqueD. Its not certain that La Braas appearance was common at his timeCWhen you think of a forest, what do you see? Just trees? Or do you see many other things, such

21、as small insects, worms, restless squirrels, singing birds, and colorful plants?The forest is a whole world of its own, and it is full of many different living things. However, even though they are all different, they have one thing in common: they all need each other in order to survive.Trees feed

22、the animals of the forest. They make food in their leaves by using sunlight to combine water and minerals （矿物质） absorbed （吸收） from the soil and air. Their network of roots sticks into the soil and helps trees absorb water, making it possible for creature to live in it.The earthworms, who live on the

23、 forest floor, also help to keep the soil livable and full of nutrients （营养）. Their holes in the ground allow air and water, which bear many minerals, to pass freely through the soil.Insects, who eat the leaves of the trees, are the main food of birds. Feeding on the insects, birds help keep forest

24、life in balance by preventing the insects from overrunning the forest.Squirrels also play their part. They feed on the seeds of the trees, yet they, like the birds, use the branches of the trees for their homes.Human beings are like the living things in the forest. We need one another in order to su

25、rvive. We rely on farmers to grow food, truck drivers to bring it to local stores, and salesmen to sell it. We need people to prepare and cook food, and others to take garbage away. Then, of course, we need doctors and nurses to take care of us when we are sick, mail carriers, telephone operators, a

26、nd newspaper delivery （递送） people to keep us in touch, as well as scientists, engineers and government leaders to improve how we live.We also need each other in another way. We need people to talk over our problems with us, to exchange ideas, and just to chat about everyday happenings with us. Think

27、 how lonely and unhappy you would be if you lived without the companionship of other people.Life is a matter of give and take. We need to help other people as much as we need other people to help us. Besides, think what a good feeling you have when you have done something for someone else!29. What c

28、an we know from the passage?A. Trees make it possible for living things to live in the forest.B. Earthworms keep the soil wet by producing water.C. Birds prevent insects from eating too many tree leaves.D. Trees can gain nutrients from other animals in the forest.30. What is the main idea of the pas

29、sage?A. The forest is very crowded. B. One tree does not make a forest.C. All living things need one another. D. Humans are like trees.31. Where is the passage most likely to have been taken from?A. A science book. B. A guidebook. C. A lesson plan. D. An advertisement.D Autonomous （自动的） cars, self-d

30、riving cars, robotic cars, or driverless cars whatever you call them are coming to a showroom（陈列室） near you.It might take a couple of years, but few people at the Geneva Motor Show would disagree that one day science fantasy （幻想） will become reality.However, while Google, BMW, Ford and IBM have been working on t
