I'd go to bed early for a class beginning at 8:00 am and my roommate would turn on the lights, leave the door open and invite friends over after I'd be trying to sleep. After a month, I changed the room.Over four years I managed to have six roommates in total. The one that was my least favorite was my old friend. This is common. Friends think that because they get along so well, sharing a room or an apartment should be OK. But the fact that they don't share a room or an apartment is part of the reason why they get along so well. That separation of space, at the end of the day, can be the friendship saver.Living with friends can oflen hinder you from meeting new people. It means graduating from college with the same friends you went in with. S. ome people I knew when I was in college all went to the same high school and all of them lived together in college. By the time we graduated, they were still living together and had not really made any new friends.More often than not, I've seen friendships end by the decision to become roommates. Two friends of mine were friends when they went into college and shared a room but hardly spoke to each other by the end of the school year.My advice: move out and make a new friend.26. According to Paragraph 2, why did the writer move out?A. Because he wanted to live with an old friend.B. Because his roommate didn't like living with him.C. Because he was not allowed to invite his friends over.D. Because his sleep was seriously affected by his roommate's actions.27. What does the underlined word "hinder" in Paragraph 4 mean?A. Prevent.B. Encourage.C. Lead.D. Teach.28. The writer probably does NOT think that it is a good idea to __________.A. live with a s ranger in collegeB. share a room with a friend in collegeC. go to sleep early at night in collegeD. keep in touch with old friends in college29. The writer makes his point clear mainly by __________.A. referring ro dataB. asking questionsC. giving examplesD. following the order of time30. In which section of a website can we most probably read this passage?A. Life in the city.B. College life lessons.C. Plans for high school life.D. Apartment information.BVariations(变化) caused by the body's 24-hour clock may mean that it offers more protection from harmful UV rays in the early hours than later on in the day.A study on mice, published in the Proceedings of the National Academy of Sciences journal, found that their vulnerability to UV light depended on the time of the day.The body's levels of a protein called XPA, which helps repair the DNA that has been damaged by UV light, change over the course of 24 hours. Researchers foundthat mice were five times more likely to develop cancer when exposed to UV light at 4:00 am, when their XPA levels were the lowest, while at 4:00 pm they reached their peak.Humans and mice have almost the same biological clocks which.are tied to a 24-hour cycle, except that we are active during the day while mice are nocturnal.This means that if the same variation in protection from the sun occurs in humans as in mice, the effect would be the opposite, giving us more protection during the moming and less in the afternoon.Dr Aziz Sancar of the University of North Carolina, who led the research, said, "Our research would suggeat that limiting sunbathing or visits to the tanning booth io morning hours would reduce the risk of skin cancer in humans."Dr Kat Amcy of Cancer Research UK said, "Over the past few years, scientists have been gathering evidence showing that the DNA repair is linked to the celll's biological clock, and these new findings in mice just support this idea."But we don't know exactly whether this research will hold up in humans, and we would still advise people to avoid using sunbeds or getting sunburnt at any time of the day to reduce the chances of developing skin cancer."31. What can we leam about XPA?A. Its levels don 't change during the day.B. It can be easily damaged by UV light.C. It is not very helpful to our body.D. It can repair some damaged DNA.32. According to the underlined word "nocturnal" in Paragraph 4, we know that mice are __________.A. active at nightB. of strange biological clocksC. skilled at repairing DNAD. likely to have cancer33. If the above research holds up in humans, we can guess that for humans __________.A. it is OK to get sunburnt at any time of the dayB. using sunbeds in the afternoon is totally safeC. the risk of getting cancer is the highest in the morningD. the risk of getting skin cancer is higher in the afternoon than in the morning34. Dr Kat Amey would agree that __________.A. the research is useless to human beingsB. the DNA repair has something to do with the cell's biological clockC. humans are less likely to get cancer than mice when exposed to UV lightD. it is hard for human beings to reduce the chances of developing skin cancer35. Mice are most likely to develop skin cancer when they are exposed to UV light at around __________.A. 4:00 pmB. 8:00 amC. 8:00 pm D 4:00 amCOf all the planets, none has captured the world's imagination like Mars. Its reddish color and changes in brightness over time make the planet an unforgettable sight.In Cosmos, the television science series from the 1980s, scientist Carl Sagan talked about some traditional ideas about Mars. Some of these ideas are from the English science fiction writer H.G. Wells' The War of ihe Worlds. Others are from the mistaken science of Percival Lowell, the American astronomer who believed intelligent beings lived on Mars. Wells described Martians as threatening. Lowell imagined them as the hopeful engineers of great works. Carl Sagan said that both ideas influenced the public deeply.Today, Mars continues to excite humans —not as the object of science fiction but of scientific study. Space scientists have collected a wealth of information from spacecrafts that have orbited, landed on and dug into theMartian surface.The Smithsonian's "Mars Day" offered a chance for people of all ages to touch Mars, or at least a piece of it. Allison and Alycia from Silver Spring, Maryland, brought their children, Grace, Sam, Ryan and Emma. They heard about Mars and its geology from experts. They could see a test version of the Viking landers that reached Mars in July of 1976. They also saw meteorites (陨星) known to have come from the red, or reddish planet. Eight-year-old Sam learned that the ancient description of Mars as red is not exactly right. He said, "It's actually orangish more than red and it's also kind of brown." Emma is six. She learned about the volcanic activity that has shaped the surface of Mars. She said, "The closest thing to Mars —the stuff —is from volcanoes mostly.""Mars Day" offered Allison and Alycia's children a chance to learn more about a world that they are very likely to set foot on within their lifetimes.36. What is Paragraph 2 mainly about?A. Why Martians wcre considered threatening.B. Why Mars has captured the world's imagination.C. What people generally thought of Mars in the past.D. How H.G. Wells got the idea for his science fiction.37.

Sam would probably agree that __________.A. Mars is not really redB. no meteorites have come from MarsC. Mars cannot be described as a little brownD. the ancient description of Mars' color is true39. What is the writer's attitude toward the idea that humans will set foot on Mars?A. He thinks it may happen in this year.B. He thinks it will always remain a dream.C. He thinks it will come true within hundreds of years.D. He thinks it may happen in the following decades.40. The Smithsonian's "Mars Day" might NOT offer people a chance to __________.A. learn about the surface of MarsB. see a test version of some Viking landersC. see meteorites known to have come from MarsD. sit in a spacccraft to experience the life of an astronautDThe largest conference on AIDS vaccine (疫苗) development is being held in Bangkok, Thailand. Organizers of the conference said, "A safe and effective AIDS vaccine would be one of the greatest public health advances ever." But they also admit it's one of the "greatest scientific challenges".In recrnt months, the public has tutned their attemion on AIDS vaccine research to what's happening in prevention. Studies show that antiretroviral drugs, when taken by an infected person, can prevent HIV transmission (传染) to a non-infected person. They also show that non-HIV-infected people can take the drugs as a preventive measure.But while there have been prevention advances, vaccine researchers are beginning new work to find what are called broadly neutralizing antibodies (杭体). If successful, they would be able to block the many, many different strains of HIV that now exist.Warren, head of the AIDS Vaccine Advocacy Coalition (A V AC), said there was success in 2009 of the RV-144 trial in Thailand. It proved that an AIDS vaccine is possible. It was the largest AIDS vaccine trial ever, with thousands of people taking part in it. "We got the result two years ago, but it's not as if that trial ended. For the last two years, an international team has been looking at the samples that were collected at that time. They have been trying to find out why that vaccine worked," he said.In the early days of AIDS vaccine research, cooperation was not as common as it is today. In fact, many believed the sharing of data could hurt a researcher's chances of publishing the work and receiving credit for it. Warren said, "Now people who might be seen as competitors in some ways are all working together to try to understand why that vaccine worked."41. Organizers of the conference think that __________. .A. inventing a safe and effective AIDS vaccine is impossibleB. AIDS vaccine development is going very wellC. a safe and effective AIDS vaccine will exist in no timeD. inventing a safe and effective AIDS vaccine is difficult42. What' s the function of antiretroviral drugs?A. It can kill HIV.B. It can cure people with AIDS.C. It can prevent HIV fiom spreading.D. It can make people wiih HIV healthier.43. What does the underlined word "they" in Paragraph 3 refer to?A. Vaccine researchers.B. Neutralizing antibodies.C. Prevention advances.D. Different strains of HIV.44. According to Pardgraph 4, it is still unknown __________.A. whether an AIDS vaccine is possibleB. how many people took part in the RV-144 trial in 2009C. when the result of the RV-144 trial came outD. why the AIDS vaccine used in the RV-144 trial worked45. We can leam from the last paragraph that __________.A. the competition among researchers on AIDS vaccine is fiercer than beforeB. researchers on AIDS vaccine now don't think it's a good idea to share dataC. researchers on AIDS vaccine are now more willing to work togetherD. no rescarchcrs on AIDS vaccine are trying to publish their work第二节信息匹配（共5小题；每小题2分，满分10分）阅读下列应用文及相关信息，并按照要求匹配信息。
