Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years, the planet was much colder than it is now .During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.
A new study from Switzerland throws light on where ice sheets（冰川）inched during the ice age. It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern regions.
This surprised the researchers from the University of Bern. Scientists have long assumed（假设）that most of the ice that melted was in the Northern hemisphere（半球）during the 30,000-year long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land .If surrendered by sea the ice can easily just slip into the ocean instead of building up.
The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence of how temperatures and currents actually changed during that time. The model showed that if it was only in the Northern hemisphere that ice melted, there would have been a bigger impact（影响）on ocean currents （洋流）and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too. The only reasonable conclusion, the scientists could make, was that ice melted equally in the North and the South.
It is still a mystery as to what caused the temperature changes that caused the ice to melt.The North Pole is surrounded by land ,while the South Pole is surrounded by the Antarctic Ocean. So scientists thought that .
| A．most of the ice melted in the Northern hemisphere |
| B．most of the ice melted in the Southern hemisphere |
| C．The North Pole is colder than South Pole |
| D．The South Pole is colder than North Pole |
We can learn from the passage .

Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.
Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.
Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here's where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles —making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles—so it appeared to be smaller than the real smaller orange circle.
When young children aged 4 to 6 looked at these tricky pictures, they weren't fooled—they were still able to find the bigger circle with roughly the same accuracy(准确性) as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.
As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they're more likely to fall for this kind of visual trick.Doherty and his team of scientists did an experiment to evaluate_____________.
| A．children's and adults' eye-sight |
| B．people's ability to see accurately |
| C．children's and adults' brains |
| D．the influence of people's age |
When asked to find the larger circle,_____________.
| A．children at 6 got it wrong 79 % of the time with no gray ones around |
| B．only adults over 18 got it right 95% of the time with gray ones around |
| C．children at 4 got it right about 79 % of the time with gray ones around |
| D．adults got it right most of the time with gray ones around |
According to the passage, we can know that_____________.
| A．a smaller orange circle appears bigger on a white background |
| B．an orange circle appears bigger than a gray one of the same size |
| C．a circle surrounded by other circles looks bigger than its real size |
| D．a circle surrounded by bigger ones looks smaller than its real size |
Why are younger children not fooled?_____________.
| A．Because their brain can hardly notice related things together. |
| B．Because older people are influenced by their experience. |
| C．Because people's eyes become weaker as they grow older. |
| D．Because they are smarter than older children and adults. |
American culture is unique because it is formed and developed under certain conditions. The major factors contributing to the making of this new nation and the forming of a new culture are the hard environment, ethnic diversity (多样性；差异) and plural religion, which is quite different from other nations in the world. What is more, these elements are still influencing the American culture.
The early immigrants（移民）who were English Puritans settled down in northeast part of America from 1607 to 1892. Frontiers were pushed further west. The frontiersmen looked for a land of rich resources and a land of promise, opportunity and freedom. Actually they looked for a better life. So individualism(个人主义), self-reliance, and equality of opportunity have perhaps been the values most closely associated with the frontier heritage（遗产）of America.
In history, people from different countries in the world rushed to America three times. They brought their own culture to America and later on, different cultures were mixed together. Thus the unique American culture was formed, a common cultural life with commonly shared values.
The fundamental American belief in individual freedom and the fight of individuals to practice their own religion is at the center of religious experience in the United States. The great diversity of ethnic backgrounds has produced religious pluralism(多元化); almost all of the religions of the world are now practiced in the United States.
Nowadays, we can see the continual influence of the three elements in the current American society. American family is typically parents and their unmarried children. Middle-aged and elderly people generally do not live with their married children. The people in America have a very strong desire to start a new life in a new place. Quite a number of people change residences every year. The average American moves fourteen times in his lifetime. We can learn from this article that ________.
| A．the population of the United States includes a large variety of ethnic groups |
| B．the early immigrants brought about the unique American culture |
| C．people in the world once rushed to America because of its unique culture |
| D．the American family members don't get along well with each other |
What's the author's attitude towards American culture?
| A．He is critical of it. |
| B．He admires it very much. |
| C．He just states the facts. |
| D．He looks down upon it. |
The last paragraph is about________.
| A．the family structure in American society |
| B．the influence of the three elements in the current American society |
| C．the new life style of American family |
| D．the reason why American people like to change residences |

You're in a department store and you see a couple of attractive young women looking at a sweater. You listen to their conversation:
"I can't believe it-----a Lorenzo Bertolla! They are almost impossible to find. Isn't it beautiful? And it's a lot cheaper than the one Sara bought in Rome."
They leave and you go over to see this incredible sweater. It's nice and the price is right. You've never heard of Lorenzo Bertolla, but those girls looked really stylish. They must know. So, you buy it. You never realize that those young women are employees of an advertising agency. They are actually paid to go from store to store, talking loudly about Lorenzo Bertolla clothes.
Every day we notice what people are wearing, driving and eating. If the person looks cool, the product seems cool, too. This is the secret of undercover marketing. Companies from Ford to Nike are starting to use it.
Undercover marketing is important because it reaches people that don't pay attention to traditional advertising. This is particularly true of the MTV generation ---- consumers between the age of 18 and 34. It is a golden group. They have a lot of money to spend, but they don't trust ads.
So advertising agencies hire young actors to "perform" in bars and other places where young adults go. Some people might call this practice deceptive (骗人的), but marketing executive Jonathan Ressler calls it creative. "Look at traditional advertising. Its effectiveness is decreasing." However, one might ask what exactly is "real" of young women pretending to be enthusiastic about a sweater? Advertising executives would say it's no less real than an ad. The difference is that you know an ad is trying to persuade you to buy something. You don' t know when a conversation you overhear is just a performance.The two attractive young women were talking so that they could _____.
| A．get the sweater at a lower price |
| B．decide on buying the sweater |
| C．be admired by other shoppers |
| D．be heard by people around |
Lorenzo Bertolla is _____.
| A．a very popular male singer |
| B．an advertising agency |
| C．the brand name of a sweater |
| D．a clothing company in Rome |
Which of the following can be inferred from the passage?
| A．Traditional advertising will soon disappear in the market. |
| B．The MTV generation tend to be more easily influenced by ads. |
| C．Undercover marketing will surely be banned soon by the government. |
| D．Traditional advertising is becoming less effective because it's too direct. |
Which of the following would be the best title for the text?
| A．Two Attractive Shoppers |
| B．Lorenzo Bertolla Sweaters |
| C．Undercover Marketing |
| D．Ways of Advertising |

Arthur Miller (1915-2005) is universally recognized as one of the greatest dramatists of the 20thcentury. Miller's father had moved to the USA from Austria Hungary, drawn like so many others by the "Great American Dream". However, he experienced severe financial hardship when his family business was ruined in the Great Depression of the early 1930s.
Miller's most famous play, Death of a Salesman, is a powerful attack on the American system, with its aggressive way of doing business and its insistence（坚持，强调） on money and social status as indicators of worth. In Willy Loman, the hero of the play, we see a man who has got into trouble with this system. Willy is "burnt out" and in the cruel world of business there is no room for sentiment（感伤）: if he can't do the work, then he is no good to his employer, the Wagner Company, and he must go. Willy is painfully aware of this, and at a loss as to what to do with his lack of success. He refuses to face the fact that he has failed and kills himself in the end.
When it was first staged in 1949, the play was greeted with enthusiastic reviews, and it won the Tony Award for Best Play, the New York Drama Critics' Circle Award, and the Pulitzer Prize for Drama. It was the first play to win all three of these major awards.
