6．Every year a couple of things rise to the top of the"must have"list，becoming the season's popular gifts．Hundreds of people line up outside stores，hoping to buy the gifts．Such gifts are examples of social epidemics（流行病）---cases when many people do the same thing at the same time．Why do we end up with the same presents？It could be that the popular gifts are simply better than the rest．But more likely，a gift's popularity is random（任意的）．
People's shopping behavior is not independent．Our behavior depends on the behavior of those around us．This influences both what people talk about and what they buy．Conversations are often driven to the common ground，so we talk about celebrities （like Lady Gaga），the weather or the local sports team．When it comes to the presents we are buying，we tend（倾向于） to bring up the things we think others have heard of．
Social influence leads us to buy what other people buy．Some scientists recently did an experiment．In the study，people visited a website where they could listen to songs and download them for free．Some people were given information about what previous（先前的） site visitors had downloaded，and this led to convergence（趋同）：People tended to download songs others had chosen．In addition，participants（参与者） in the experiment were divided into eight groups and could see the previous downloads only people of their own group．What the researchers found was powerful．Across the separate groups，the songs that became"hits"were greatly different．The top song in one social world was a failure in another．Why？Well，if people imitate（模仿） others，then whatever gets an early advantage in popularity is likely to stand out．
As with these"hit"songs，the popular gifts depend less on their qualities but more on human psychology（心理）．So as you stand in long line trying to get whatever it is that everyone else seems to want this year，stop to realize that this may have less to do with the gift and more about our instincts（本能）．And remember that whoever you are giving the present to may be just as happy with something else．

56．What's the passage mainly about？A
A．Our shopping behavior is influenced by our society．
B．We should learn to depend on ourselves in our life．
C．Everyone should line up and buy the gifts in order．
D．We should have to follow the rules in the market．

58．Why does the writer show the experiment to us in the third paragraph？D
A．To tell us how to carry out an experiment carefully．
B．To make us pay more attention to the achievements．
C．To explain why people buy different kinds of gifts crazily．
D．To show how social influence shapes common results．
59．We can make a conclusion from the passage thatA．
A．the gift you offer may not be the favorite of its owner
B．the price of all the gifts will be raised in a short time
C．we must make sure there is a trade mark on the gift
D．more and more gifts may be returned to the stores soon．

Biologists in Alaska are counting walruses （海象） in the Arctic  Ocean．The aim：to decide whether the walrus is an endangered species （物种）．
In 1990，biologists counted 201，039walruses in the Arctic Ocean．Now，over 20years later，it seems there are fewer．After three years of counting，the US Fish and Wildlife Service estimates that there are only 15，164walruses in the area．But，scientists say，"They've not finished counting．"
"We're still working on the final population estimate，"said Suzann．She is a wildlife biologist with the US Fish and Wildlife Service．
Endangered Species？
What's a possible reason for the lower walrus count？Brendan Cummings，a spokesperson for
the Center for Biological Diversity （多样性），thinks many walruses are dying．He believes global warming is melting the ice in the waters between Alaska and Russia．That's the area where most walruses live．However，they can't live without ice．
  But other scientists aren't so sure that the walruses are dying out．The US Fish and Wildlife Service biologist Doug Bum said，"We realized we were missing a lot of walrus groups．"So the walrus count goes on．The counting hasn't been easy．Scientists sometimes have to guess the number of walruses that are underwater．
US law requires scientists to count the walruses every three years．Then，if the mammals （哺乳动物） turn out to be an endangered species，they will be counted every year．

66、What's the purpose of counting walruses in the Arctic Ocean？．C
A、To study the living habits of walruses．
B、To show the bad environment of the earth．
C、To see whether the walruses belong to the endangered animals．
D、To see whether the Arctic Ocean is suitable for people to live in．
67、What does the underlined word"estimate"mean in Chinese？B
A、创造
B、估算
C、分析
D、制造
68、According to the US law，scientists will count the walruses every year if they areB．
A、missing
B、endangered
C、sold out
D、under the water
69、Which of the following statements is TRUE？D
A、The counting of the walrus is easy．
B、Brendan Cummings is a biologist of the US Fish and Wildlife Service．
C、In 1990，biologists counted only 15，164walruses in the Arctic Ocean．
D、Brendan Cummings believes global Warming makes the walruses fewer．
70、What is the best title of the passage？D
A、Global Warming
B、Protect the Animals
C、Biologists'Work
D、Worry about Walruses．

The 2012Olympic Games will take place in London．This summer，Chinese sports fans will be able to watch the exciting games in 3-D on CCTV．When you watch 3-D movies or TV，you have to wear a special pair of glasses．The 3-D glasses make the images from the screen look like they are there in the room with you．
Three-dimensional，or 3-D，means having three dimensions （维度）：width，height and depth.3-D technology is based on the way the human brain and eyes work．Because the pupils of a person's eyes are about 6.5cm apart，when we look at something，each eye sees it from a different angle （角度）．Our eyes send the two images to our brain，and the brain puts them together．The small difference between the image from the right eye and the image from the left eye allows us to see depth．
When we view media such as pictures and television in two dimensions，each eye gets the same information．That is because the image has no real depth，and there is only one way of viewing it．So the goal of 3-D technology is to get a different image into each eye of the viewer．It uses two film projectors．One projects a left eye image and the other projects a right eye image．The 3-D glasses allow us to see a different image in each eye．
While watching 3-D films，we feel that we are actually in the same environment as the things we're watching．However，it also has its disadvantages．The 3-D glasses work by controlling the amount of light that reaches the eyes．It makes the screen look darker．What's more，people with eye problems may get headaches if they spend too much time watching 3-D movies，because their brains need to work harder to"read"the images．

2．Two Chinese spacecrafts successfully completed China's first space docking early November 3，2011，which has taken the country a step closer to building its own space station．
Nearly two days after its launch，the unmanned spacecraft Shenzhou VIII docked with the space lab module Tiangong I more than 343km above the earth surface．Shenzhou VIII and Tiangong I took apart after flying together for 12days．On the 14th of November，the two spacecrafts finished the second docking．Then Shenzhou VIII parted from Tiangong I again and returned to the earth safely on the 17th．Tiangong I is still traveling around the earth in the space，waiting for the arrival of Shenzhou IX and X and so on in the near future．
That marked another great leap for China's space program and made China the third country in the world，after the United States and Russia，to master the space docking technique （空间对接技术）．
The world's first space docking was achieved in 1966，when the manned U．S，spacecraft Gemini 8 （双子星8号） docked with an unmanned Agena Target Vehicle （阿金纳目标飞行器）．Space docking is necessary to explore space beyond Earth's orbit．"The capability increases China's ability to act independently in space，as well as its ability to work together with others，"said Gregory Kulacki，a U．S．space scientist and senior analyst．
"With the success of its first space docking，China is now equipped with the basic technology and ability required for the construction of a space station，"said Zhou Jianping，chief designer of China's manned space program．"The country is on its way to building a permanent manned space station around 2020．"

Have you ever wondered why birds sing？Maybe you thought that they were just happy．After all，you probably also sing or whistle when you are happy．
Some scientists believe that birds do sing some of the time just because they are happy．However，they sing most of the time for a very different reason．Their singing is actually a warning to other birds to stay out of their territory．
Do you know what a"territory"is？A territory is an area that an animal，usually the male，claims（宣称）as its own．Only he and his family are welcome there．No other families of the same species（物种）are welcome．Your yard and house are your territory where only your family and friends are welcome．（76） If a stranger should enter your territory andwant to hurt you，you might shout．Probably this would be enough to frightenhim away．
If so，you have actually frightened the stranger away without having to fight him．（78）一只鸟也将会做同样的事．But he expects an outsider almost any time，especially at nesting （筑巢）season．So he is screaming（尖叫）all the time，whether he can see an outsider or not．This screaming is what we call a bird's song，and it is usually enough to keep an outsider away．
Birds sing loudest in spring when they are trying to attract a mate（同伴）and warn others not to enter the territory of theirs．
You can see that birds have a language of their own．Most of it has to do with attracting mates and setting up territories．
