56、epression.Signs may include loss of interest or pleasure in most activities，low energy levels and thoughts of death or suicide.In the new study，American investigators designed an experiment that exposed hamsters(仓鼠) to different colors.The researchers chose hamsters because they are nocturnal，which

57、means they sleep during the day and are active at night.The animals were separated into four groups.One group of hamsters was kept in the dark during their nighttime period.Another group was placed in front of a blue light，a third group slept in front of a white light，while a fourth was put in front

58、 of a red light.After four weeks，the researchers noted how much sugary water the hamsters drank.They found that the most depressed animals drank the least amount of water.Randy Nelson heads the Department of Neuroscience at Ohio State University.He says animals that slept in blue and white light app

59、eared to be the most depressed.“What we saw is that these animals didnt show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign，while if they were in the dim red light，they did not.”Randy Nelson notes that photosensitive(感光的) cells in the eyes h

60、ave little to do with eyesight.He says these cells send signals to the area of the brain that controls what has been called the natural sleepwake cycle.He says theres a lot of blue in white light.This explains why the blue light and white light hamsters appear to be more depressed than the hamsters

61、seeing red light or darkness.1Researchers use hamsters in the experiment because .Athey are similar to humans in dealing with colorsBthey are easy to observe and studyCthey are sensitive to colors like human beingsDthey are active at night and sleep during the day答案D解析细节理解题。第二段说，选择仓鼠作为实验对象是因为它们白天睡觉，

62、夜间活动，因此选D。2What sign shows that the hamsters are depressed?AThey drink less sugary water.BThey dont sleep well.CTheir eyesight becomes worse.DTheir energy level becomes low.答案A解析细节理解题。第四段说，研究人员发现喝糖水最少的仓鼠最为抑郁，因此选A。3 tends to cause hamsters to be depressed.ADim light BRed lightCBlue light DDarkness答案C

63、解析细节理解题。第五段说，在蓝色和白色灯光下睡觉的仓鼠表现得最为抑郁，因此选C。4What can help people who work late at night to avoid being depressed?ANot being exposed to dim red light when using computers.BEquipping their computer screen to put it more in the reddish light.CLiving or working in low levels of light overnight.DGoing to se

64、e doctors of clinical depression regularly for help.答案B解析推理判断题。最后一段说，生活在蓝色和白色灯光下的仓鼠比生活在红色或黑暗中的仓鼠更抑郁，因此在红色光线中工作能防止抑郁，故B项正确。BWelcome to the world of multitaskinga place where the measure of a person is how many jobs they can perform at the same time.In fact，if experts are to be believed，multitasking i

65、s a disastrous idea.One of the opponents of multitasking is Dr.Clifford Nass，a professor at Stanford University.“People who multitask frequently are less able to pay attention；theyre worse at managing their memory，” he said.In his opinion，the loss that we get with multitasking is harmless in some si

66、tuations，for example，part of doing business in the digital world；but you cant do serious work like writing，thinking or solving an important problem this way.You do worse even as you think youre doing better.All the time the research points to a simple fact：the brain cannot cope.When you stop midway

67、through composing a report to check an email，you force your brain to stop and regroup.It is like pressing the pause button during a movie，meaning the film takes longer to watch.And as for Dr.Nass，the problems extend beyond the brain.Young people who frequently multitask are not as socially and emoti

68、onally healthy as those who dont.They just feel more emotionally satisfied and the feeling is so good and they are bound to desire it again.Todd Oppenheimer，a writer said，“Weve become a very shortterm society and dont reward people for taking a lot of time on something.” He fears we may end up losin

69、g the next generation of great thinkers.“Its really unfortunate because the longterm challenges of our worldenvironmental issues，financial issuesrequire people to think wisely about the longterm consequences of what they do.And its no coincidence that the kind of people who do think longterm dont mu

70、ltitask.”5According to Dr.Nass，multitasking .Amakes the performance emotionally affected onlyBcontributes to memorizing various thingsCmay result in losing the next generation of great thinkersDcan be performed using digital tools答案D解析细节理解题。关于同时做很多事，第二段说在有些情况下，比如在数字化的世界里做生意(doing business in the dig

71、ital world)是无害的，因此选D。文章说同时做很多事会影响我们在人际交往和情感方面的健康(A错)；会使我们记性更差(B错)；一位叫Todd的作家说这样可能会使我们失去未来一代伟大的思想家(C错)。6From the passage，we can tell .Athe loss that we get with multitasking is harmlessBwe mistakenly believe that were doing better by switching between tasksCmultitasking does harm to us in every areaD

72、for every task you add to your multitasking，you can finish your goal more quickly答案B解析推理判断题。文章开头说，“欢迎来到同时做很多事的世界，在这里，对一个人的衡量标准是他能同时开展多少项工作”，接着说，这个想法实际上害人不浅，因此B项正确；从第二段可知A、C错，因为multitasking有时是无害的，有时则会妨碍我们；第二段最后一句通过打比方的方式告诉我们，这样会使事情做得更慢(D错)。7Which of the following is a multitasking addict?AYou turn yo

73、ur cellphone to silence when youre out to dine with friends.BYou watch from start to finish without distraction when playing a DVD.CYou have your office desk covered with paperwork from various unfinished projects.DYou feel that when you try to do too much at once，the result always suffers.答案C解析推理判断

74、题。从本题四个选项的陈述看，A、B、D都是专心在做一件事，C项说办公桌上放着各种没有完工的项目的文书工作，这里的various unfinished projects属于multitasking。故选C。8The author mainly wants to tell us .Athe less you switch，the better you doBit is more efficient to do things all in a mixed wayCit takes longer for us to become a great thinkerDwe shouldnt be lazy

75、if we want to accomplish many tasks答案A解析主旨大意题。全文通过斯坦福大学一位教授的话告诉我们，同时做很多事不仅不能提高工作效率，反而对我们的健康不利，因此A项“角色转换越少，做得就越好”是本文的主题。.阅读填空Dont just stand thereYoure rushing to work and a man ahead of you suddenly falls down and becomes unconscious on the sidewalk.Do you stop to help？In a study of bystanders，it wa

76、s found that some people keep on walking rather than stop and get involved.“There is a tendency to decide that no action is needed，”says Ervin Staub，a psychologist.“ 9 ” Here are some common thoughts that might prevent you from helping.Why should I be the one to help？Im probably not the most compete

77、nt person in this crowd. 10 I dont want to be embarrassed.No one else looks concerned；this must not be a problem.Time and again，good and caring people fail to come to the aid of others.Why? 11 Lets say you see vapors coming out of a building.You ask yourself，“Is it steam or smoke？” If you are not su

78、re，you look to other people for a clue about how to react.If you see other people are doing nothing，you think，“Of course，thats just steam.”You dont want it to be smoke，because then you would have to do something about it.Another wellknown deterrent(制止物) to action is known as “the bystander effect” 1

79、2 For example，if you are the only person in the world who can act to save someone in a dangerous situation，you are more likely to act.“If you spot trouble，force yourself to stop and evaluate the situation instead of walking on，”says Ervin Staub.“ 13 You dont have to take on the entire responsibility

80、 of being helpful.Once you take action，most people will also help.”AThen try to involve other people.BOur society is becoming less sensitive.CWhat if the person doesnt really need help?DNo one wants to risk looking foolish in front of others.EThe first thoughts that come into your mind often keep yo

81、u from offering help.FOne thing we do know is that the more ambiguous a situation is，the less likely people are to help.GThis says that the more people there are observing an emergency，the less responsible each one of them personally feels.答案9.E10.C11.F12.G13.A.写作素材(关于英语)提示：黑体部分用本单元词汇表达，并且请使用so that
