Archimedes was a famous Greek mathematician and scientist. He was born around 287 B. C. and he died in 212 B. C.
Archimedes was most known for one specific idea that he came up with. “Archimedes’s Principle（定律）”states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold of the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than the water, while the gold weighs more.
It is believed the Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know whether his crown（王冠）was pure gold or a mixture of gold and silver. The king, of course, didn’t want to melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of his tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith（金匠）was found guilty（有罪的）of trying to cheat the king.

China is likely to surpass the U.S. to become world’s largest online game market this year, according to a recent report by market research firm iResearch. China’s online game market generated revenue(总收入) of 20.8 billion yuan($3.04 billion) in 2008, up 52.2% over the previous year. Over 80% of the revenue came from big, multiplayer online games, with the rest generated from Web games and mobile games.
The overall market is expected to keep growing at an average annual rate of 20% in the coming five years. And iResearch forecasts that the Chinese online market will be worth more than 68 billion yuan by 2012, which will account for almost half of the global market by then. At present, U.S., China and Korea are the world’s top three largest online game markets, making up about 29%, 27% and 21% respectively of the global online game market, according to the report.
U.S. game companies derive a major part of their revenue from sales of games overseas. South Korea’s online game industry generates half of its revenue from games in its home market. In China, however, most of the money comes directly from its own game players. Negatively influenced by the global economic downturn, both the U.S. and Korea markets will see a drop in game exporting, iResearch estimates.
In China, the enormous base and fast growing of online gamers will further boost China’s online game industry, said the report. China is currently home to 55.5 million online game players, according to the latest stats by the China Internet Network Information Center(CNNIC). In its report, iResearch found that figures for gamers under 18 and above 40 grew at their fastest rate yet last year, though it didn’t disclose specifics.
55．The second and third paragraphs show that ________.
A．The global online game market will be worth more than 136 billion yuan in 2012.
B．China’s online game market increased by 20% in 2008.
C．China’s online game market will become 60% less in 2009.
D．US, China and Korea together account for 90% of the global online game market.
56．China’s online game industry is different from that of the US and Korea because it’s ________.
A．made up of online, Web and mobile games
B．easily affected by the global economy
C．mainly based upon its home market
D．among the three largest online game markets
57．Which of the following things is mentioned as a factor in the rapid development of China’s online game industry?
A．The rapid growth of online gamers in China.
B．A drop in game imports to China.
C．The global economic downturn.
D．The development of technology in China.
58．According to the last paragraph, which of the following is TRUE?
A．CNNC and iResearch worked together on the report.
B．Gamers under 18 were one of the age groups which grew the fastest last year.
C．At present there are 55.5 million online game providers in China.
D．The statements of CNNC and iResearch are contradictory.

Two experts did some experiments on two groups of people — one who tended to sleep less than the
people around them and the other group more.
According to their report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men automatically began to cut down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
In general, these “short sleepers” appeared with ambition, active, energetic, cheerful, and conformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or even worked full time while going to school. And many of them 
had a strong urge to appear “acceptable” or “outstanding” to their friends and associates.
When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering them. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.
The experts also stated that those “long sleepers” were quite different indeed. They reported that those men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were a bit concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than the “short sleepers did.
Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly express it that being asleep was a good escape from their daily problems.
All in all, proper time of sleeping should be admired, not too long, neither too short.
【小题1】According to the report, ______.
| A．many “short sleepers” need less sleep just by nature |
| B．many “short sleepers” are obliged to reduce sleep time by work |
| C．long sleepers sleep a longer period of time during the day |
| D．many “long sleepers” formed sleeping habit during childhood |
| A．sleep is a very efficient escape from the reality |
| B．sleep is just an item which should be denied by them |
| C．sleep might be a disturbing thing for their daily business |
| D．sleep is the best way to deal with psychological troubles |
| A．are ideally energetic under the pressures of life |
| B．often ignore the ill effect of not enough sleep |
C．do not know how to re lax themselves p roperly |
| D．are more unlikely to run into mental problems |
| A．appeared troubled | B．became energetic |
| C．felt dissatisfied | D．were much depressed |
| A．If one sleeps improperly, his performance suffers and his memory is weakened |
| B．The sleep patterns of short sleepers are the same as those shown by “long sleepers” |
| C．Long and short sleepers differ in their attitudes towards sleep |
| D．Short sleepers may have been better off if they have more rest |
