Read the following article and select the best answer. Article: For years and years people have been saying that the rail ways are dead. "We can do without railways", people say as if motorcars and planes have made the railways unnecessary. We all keep hearing that trains are slow, that they lose money, and that they're dying. But this is far from the truth. In these days of expensive oil, the railways have become highly competitive with motorcars and planes. If you want to carry people or goods from place to place, they are cheaper than planes. And they have much in common with planes. A plane goes in a straight line and so does a railway. What is more, it takes you from the heart of a city into the heart of another. It doesn't leave you as a plane does, miles and miles from the city center. It doesn't hold you up as a car does, in endless traffic jams. And a single train can carry goods which no plane or motorcar could ever do. Far from being dead, the railways are very much alive. Modern railway lines give you a smooth, untroubled journey. Where else can you eat well, sleep in comfort, feel safe and enjoy the scene while you are traveling at speed at the same time? And we are only at the beginning,for we have just entered the age of _ . Trains are traveling at 150 miles an hour and more. Soon we will be wondering why we spent so much on motorways we can't use because we have not enough money to buy the oil and planes we can't fly in for the same reason. Question: Some people think the railways are unnecessary for many reasons except that _ . - planes and motorcars have taken the place of trains - oil is expensive today - trains are slow - always lose money
oil is expensive today

Read the following article and select the best answer. Article: My father had returned from his business visit to London when I came in, rather late, to supper. I could tell at once that he and my mother had been discussing something. In that half- playful, half-serious way I knew so well, he said, "How would you like to go to Eton?" " You bet, " I cried quickly catching the joke. Everyone knew it was the most expensive, the most famous of schools. You had to be entered at birth, if not before. Besides, even at 12 or 13, I. understood my father. He disliked any form of showing off. He always knew his proper station in life, which was in the middle of the middle class; our house was medium-sized; he had avoided joining Royal Liverpool Golf Club and went to a smaller one instead; though once he had got a second-hand Rolls-Royce at a remarkably low price, he felt embarrassed driving it, and quickly changed it for an Austin 1100. This could only be his delightful way of telling me that the whole boarding school idea was to be dropped. Alas ! I should also have remembered that he had a liking for being different from everyone else, if it did not conflict with his fear of drawing attention to himself. It seemed that he had happened to be talking to Graham Brown of the London office, a very nice fellow, and Craham had a friend who had just entered his boy at the school, and while he was in that part of the world he thought he might just as well phone them. I remember my eyes stinging and my hands shaking with the puzzlement of my feelings. There was excitement, at the heart of great sadness. "Oh, he doesn't want to go away , " said my mother, " You shouldn't go on like this. " "It's up to him, " said my father. "He can make up his own mind. " Question: From the text, we can know that Eden is _ . - a famous school - an expensive car - one of the author's friends - one of the father's colleagues
(Answer)
a famous school

Read the following article and select the best answer. Article: Sheng Huizhen's life story is typical of immigrants who have succeeded in America. After getting her PhD in biochemistry, she got a job as a researcher at the National Institutes of Health. She got a green card, bought a house in Maryland and worked her way up all the time. But then she moved back to China. A law in America stopped the use of public money for research on human embryos . This prevented her from doing the kind of work she wanted to do. The Chinese government attracts her to return with $75,000 for a new lab. She could use the lab to do her research. " Maybe because of the culture, the public in China are friendlier to the research," said Sheng, 55 , whose family remains in the United States. Attracted by support and a scientific environment more open to certain types of experiments, China's long-lost scientists are coming back. Besides, China announced that it would double its research-and-development spending by 2012, to about $69 billion. The returning scientists are very happy about that. In recent years, more than 275,000 have come back. Many of these "sea turtles" , as they are known, have returned with degrees in science or engineering. They are going to the Chinese Academy of Sciences, where 81 percent of the members are returning scientists. Fifty thousand of the returning scientists are starting their own companies, according to China's Ministry of Education, pushing the development in science. Question: Why did Sheng Huizhen return to China? - Because her family remains in China. - Because she couldn't adapt to the life in America. - Because China supports her research. - Because she was tired of living abroad.
Because China supports her research.
