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 ago, 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 sheds light on where ice sheets melted 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 areas. This surprised the researchers from the University of Bern.
Scientists have long assumed（认为） 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 surrounded 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.
1.The underlined phrase “sheds light on” (in paragraph 3) can be replaced by .
A. throws doubts on
B. beats down on

2.We can infer from the passage .

C. volcanoes caused the ice to melt
D. researchers often use the computer models help their research work.
3.The scientists are not sure .
A. what caused the temperature changes
B. where ice sheets melted during the ice age
C. how long the ice age lasted

Most of us in China are used to paying for everything with our phones. 1.At least, this was the case for Lim Swee Say from Singapore, who found his first experience with Chinese payment methods quite impressive.

Each year, we are exposed to ten thousand a
ds on average. They try to sell us their products by using beautiful art, videos, images or slogans that are catchy. The most famous companies have highly popular logos that can be recognized by almost everybody. For those of you who have seen the movie Finding Forrester, there is that scene where Jamal walks up to some guy with a BMW and asks him what the car logo means. The man did not know the answer and since that day, whenever I see a famous company logo I try to find the meaning of it.Many think the horse on the Ferrari logo represents the horsepower of the cars they manufacture. The story behind it is far more interesting. During World War I, a pilot, Count Francesco Baracca, painted the horse on his airplane to bring him luck. He had it on his plane because it was the logo of his squadron（空军中队）. Baracca’s mother then convinced Enzo Ferrari to put the logo on his racing cars in the early 1930’s to bring good luck to the drivers. The logo then stayed the same ever since. The yellow on the background represents the birthplace of Enzo Ferrari.
Starbucks started in 1971, in Seattle. The mermaid（美人鱼）represented on the logo is now known by any coffee drinker. It is a mythological sea creature with the look of a female, the only difference being that they have a tail of a fish. The reason why Starbucks incorporated one in their company logo is that it was believed that mermaids used to sing to sailors in order to make them walk away from their ship or to ground their ships. In the 1500s, spices, tea and coffee were popular merchandise to trade. So the mermaid in the logo of Starbucks is the one that “brings” coffee and tea to the stores.
1.The writer became interested in logos of some famous brands after _______.
A. he watched an attractive movie
B. he saw a scene in a movie
C. he walked up to some guy with a BMW
D. he noticed some famous logos
2.Many companies use logos because _________.
A. people enjoy beautiful logos
B. people are more likely to buy their products
C. people can recognize the products more easily
D. people are interested in the meanings of the logos
3.Which of the following is true according to Paragraph3?
A. Starbucks was once a company trading spices, tea and coffee.
B. Hearing mermaids sing, sailors would know the right direction.
C. Starbucks has a history of more than five hundred years.
D. The logo of Starbucks is believed to make the business years.
4.The underlined word “incorporated” in the third paragraph probably means _____.
A. included B. abandoned
C. corrected D. designed

There are many ways of defining success. It is accurate to say that each of us has our own ideas of success to the extent that each of us is responsible for setting our own goals and determining whether we have met these goals satisfactorily. Because each of us possesses unique differences in genetic ability and favorable environments in which to express these abilities, it is necessarily true that we must define success broadly.
For some people，simply being able to live their life with the least misery and sufferings is considered a success. Think of the peace of mind of the poor shepherd who tends his sheep, enjoys his simple life with his family in the beauty of nature, and who is respected because he does a good job of achieving the goals expected of him and accepted by his family and his society. On the other hand, it seems that even though some people appear to be rich in material possessions, many of them seem to be miserable and consider themselves unsuccessful when judged by their own standards of success. Because not all ventures can be successful, one should not set unrealistic goals for achieving success, but if one has self-confidence it would be unfortunate to set one's goals at too low a level of achievement.
A wise man once said to a young man who was experiencing frustration (挫折）with his own professional success, “You do not have to set your goal to reach the moon in order to have success in traveling. Sometimes one can be very successful merely by taking a walk in the park or riding the subway downtown,” The man added, "You have not really failed and spoiled your chances for success until you have been unsuccessful at something you really like，and to which you have given your best effort. ”
1.According to the first paragraph, what is implied as basic in achieving success?
A. Ability and goals. B. Goals and determination.
C. Ability and environment. D. Goals and environment.
2.Some rich people consider themselves unsuccessful because ______.
A. they haven't reached their own standards
B. their life is busy and miserable
C. they set their goals at too low a level
D. they are not rich in material possessions
3. From the last paragraph we can tell that ______.
A. success means achieving great goals
B. success comes from great goal setting
C. success has nothing to do with the distance of your travel
D. success means efforts and favorites pay off
4.The purpose of the passage is ______.
A. to talk about how to achieve success
B. to give us a clear definition of what success is
C. to state what our life goal is
D. to discuss the importance of goals
