A technique that controls immediate gas explosions by spraying them with large droplets of water is being tested by scientists at the University of Wales, United Kingdom．Instead of using the traditional fine water sprays when a gas leak is detected, the researchers have discovered that large droplets help to draw in some of the force of any explosion and provide a better way of controlling fire．
The research is based on studies made of the Piper Alpha oil rig（油井） explosion that occurred in the North Sea nine years ago killing 167 workers．The Welsh team found that by covering the gas-leak area with water droplets, the explosion and its e
ffect can be greatly reduced．
Dr Gerand Thomas, a good lecturer in physics at the university’s Center for Explosion Studies, said that it was impossible to deal with gas explosions in the same way as fires because the whole event may only last a quarter of a second and normal water sprays do not have time to be effective．
Using the droplets of water to hold explosions resulted in the water being turned into a mist that allows some force of the explosion to be reduced．The mist slows down the combustion（燃烧） process and can stop a large amount of the gas igniting （点火,燃烧）, thus greatly reducing damage by limiting pressure development．With such a system, the operator has to decide at what point after a gas leak to activate the sprays．
The Center for Explosion Studies is the first of its kind in the UK and has been purposely-built for the study and implication of industrial explosions on land and sea．Research is developed to the causes of accidental explosions and they might be prevented．Full-sized imitative buildings can be built at the center where explosions and fires are created to test preventative equipment using sensors to monitor their efficiency．
Another area that the Welsh researchers have been looking at is how materials respond to explosions．The center also carries out research requested by individual customers．Which of the following would be the best title for the passage?
| A．Piper Alpha Oil Rig Explosion |
| B．Large Droplets of Water |
| C．A New Way of Controlling Gas Explosions |
| D．The center for Explosion Studies |
The research finds that _____ in holding immediate explosion．
| A．small water sprays are better than large droplets of water |
| B．small water sprays are not as good as large droplets of water |
| C．both small water sprays and large droplets of water are good |
| D．neither small water sprays nor large droplets of water is good |
Dr Geraint Thomas implies that ______．
| A．normal water sprays can put out fire effectively |
| B．gas explosions break out more quickly than fires |
| C．fires are easier to be held than explosions |
| D．gas explosions break out so quickly that there is no way to control it |

Started in 1636, Harvard University is the oldest of all the many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard.
In the early years, these schools were much alike(*similar).Only young men went to college. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated(*毕业),most of them became ministers or teachers.
In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard’s law school. In 1825, besides Latin and Greek, Harvard began teaching modern languages, such as French and German. Soon it began teaching American history.
As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.
Today, there are many different kinds of colleges and universities. Most of them are made up of smaller schools that deal with special fields of learning. There’s so much to learn that one kind of school can’t offer it all.The oldest university in the US is _________.

Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them,“Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered,“Your brother. Because electricity travaels faster than sound waves.”“That’s every good,”Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said.“Yes, Kate.”

BEIJING, Oct. 8(Xinhua)——There are ten times as many Chinese newspapers and magazines than there were 30 years ago. That’s when the country adopted the reform and opening-up policy.
Figures from the General Administration of Press and Publication (GAPP)show there were 186 newspapers and 930 magazines in China in 1978. Today, the country has 2,081 newspapers and 9,363 different magazines.
In the meantime, official figures show China has some 600 publishing houses producing nearly 300,000 kinds of books. That’s a dramatic increase from the 105 publishers of the past that produced only 10,000 different books.
Rapid economic development and universal education since China adopted the reform has helped fuel the need for more information sources.
Under the market economy, hundreds of publishing houses and newspapers have taken steps to restructure management systems into corporations listed on the stock market.
The legal system overseeing the news and publishing industries in China has also changed over the last three decades. Since 1990 a law and five relevant(相关) regulations were adopted in 1990 to govern the sectors.
Since it started in 1993, digital publishing has flourished. Its industrial volume amounted to 20 billion yuan (2.93 billion U.S. dollars) in 2006. More than 500,000 kinds of digital books were produced last year alone in China, which is more than any other country in the world.Which of the following would be the best title for the text?

A well-dressed man entered a famous jewelry shop. He explained that he wished to buy a pearl for his wife’s birthday. The price didn’t matter. Since business had been very good for him that year. After examining a nice black one that cost $5000, he paid for the pearl in cash, shook hands with the jeweler, and left.
A few days later the man returned and said that his wife liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality, as she wanted a pair of earrings made, “Can you give me any advice on how to get such a pearl?” said the man.
