Tigers are terrible animals, but a cat is a cute animal.    As a mother, the Chinese-American writer Amy Chua is just a tiger . Her book, Battle Hymn of the Tiger Mother (《虎妈战歌》), tells us how she gives her two children education.    She says that being strict is the only way to train a child’s talent. Her kids had to obey the following rules. To begin with, her kids weren’t allowed to watch TV or play computer games. Then, they were not allowed to “ hang out ” with other kids after school. They had to be the top students in their class. And they had to practice the piano and the violin for hours every day. Of course, she believes this has brought a lot of problems for herself and her kids. But she doesn’t mind because her kids have become great. Chua says, like her, most Asian mothers are tigers because they believe their children can achieve a lot if they’re pushed hard enough. She says American mothers are really cats. They care more about their children’s self-respect (自尊). They don’t want to be strict with their kids because this may hurt their feelings. With soft words and understanding, they encourage their children to choose for themselves. So is a tiger mom better than a cat mom? It may also depend on the child.

Is there intelligent (有智力的) life on other planets? For years, scientists said “no.” or “we don’t know.” But today this is changing. Seth Shostak and Alexandra Barnett are astronomers(天文学家). They believe intelligent life exists (存在) somewhere in the universe. They also think we sill soon contact these beings(人;生物).
Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. “This is long enough for other planets to have intelligent life,” say Shostak and Barnett. The second reason is size—the universe is huge. “Tools like the Hubble Telescope(哈勃望远镜) have shown that there are at least 100 billion galaxies,” says Shostak. “And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth.”
In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes(高倍望远镜) allow scientists to discover smaller planets—the size of Mars or Earth—in other solar systems. These planets might have intelligent life.
Have beings from space already visited Earth? “Probably not,” says Shostak. “It’s a long way away. However, intelligent beings may contact us in other way, such as radio signals(信号). In fact, they may be trying to communicate with us now, but we don’t have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other.”
小题1:Seth Shostak and Alexandra Barnett are _____.
A.astronomersB.farmersC.singersD.drivers
小题2:What is the best title for Paragraph 2?

小题3:Why was it hard to look for signs of intelligent life in the universe in the past?
A.There were not any smaller planets.
B.There were not any powerful telescopes.
C.The astronomers were not interested in them.

小题4:Why haven’t beings from space visited us yet according to Shostak?

B.It’s a long way away.

小题5:What does the underlined phrase “life forms” in the last paragraph mean?

Yang Nan, 17, was happy to move to her new home in a northern area of Beijing. She was told that her neighborhood used to be rich farmland planted with vegetables, corn and wheat. But looking at the new road, beautiful parks and supermarkets, to her surprise, Yang couldn't see any sign that food was once grown there.
Yang is not alone. In recent years, many Chinese people have moved into new houses in country areas. Tall buildings have been built everywhere in the suburbs. The crops and fruit trees are no more grown there. But these changes have caused big problems too, warns Gan Zangchun, an official(官员)at the Ministry of Land and Resources(国土资源部).
"Chinese cities are growing very fast. This has made the area for farmland much smaller than before. This is really bad for the country's ability to grow food, not to mention the lives of farmers," said Gan last Monday.
As the population of China is growing all the time, the country needs more farmland to grow food for the increasing people of China. But the recent rise in house prices has made selling land a good business. A lot of land has been used to build new houses for sale. So you can see, the shortage of the farmland is now a very serious problem.
Pollution, such as, oil pollution, industrial(工业) pollution and water pollution, which makes land useless, is another reason for the big drop in China's farmland. About 2.67 million square kilometers of land in China have been polluted and turned into desert.
Today, can we use less farmland to grow enough food for more people? Of course not! The government wants China to have at least 120 million hectares(公顷) of farmland. Only in this way can we raise such a big population. But there are only about 121.8 million hectares left. "It will be really difficult to reach the goal", Gan said. He said that the government would fight illegal(非法的) land use and something useful must be done to stop farmland from becoming desert.
小题1:The article seems to tell us that_____________.
A.farmland is in danger
B.countryside is turned into towns
C.farmland has been sold
D.Chinese cities are growing fast
小题2:From what Gan Zangchun said, we know he is worrying about ____________.
A.China's development is too slow
B.the population of China is growing fast
C.Chinese people have worse life than before
D.the reduction(减少) and pollution of the farmland
小题3:What size of the land have been polluted and turned into desert?
A.120 million hectares.
B.121.8 million hectares.
C.2.67 million square kilometers.
D.Millions of square kilometers.
小题4:Which statement of the following is NOT true?
A.Yang Nan's new home is in a northern area of Beijing.
B.The country needs enough farmland so that the farmers can grow enough food for the people of China.
C.Chinese cities are growing too slowly so the government encourages people to change the farmland into towns.
D.Pollution is also an important reason for the big drop in China's farmland.
小题5:What will the government do with the problem of the drop in China's farmland?
A.Government needs farmland to grow food for the people of China.
B.Government will order not to build new towns any more.
C.Government will stop the growth of the cities in order to stop selling farmland for business.
D.Government will fight illegal land use and stop farmland from becoming dessert.

Your eyes

We’ve all heard of mermaids. They are the beautiful half-human, half-fish creatures(生物). They have the head and body of a human and the tail of a fish. We also know that mermaids only exist in fairy tales. But where did all the stories about these creatures come from? If you have ever seen a manatee, then you might have an idea.

Manatees, which are also called sea cows, are mammals(哺乳动物) that live in the sea. Since they are mammals, they have to swim up to the surface to breathe air. Many people believe that the story of the mermaid began with the ancient sailors who saw the manatees putting their heads out of the water to breathe. Because manatees are upright when they do this, it looks like they are standing. If a sailor saw a manatee doing this from far away across the sea, it is possible that the sailor would mistake the manatee for a creature that is half-human, half-fish.
Mermaids are described as having very long hair. This is probably because manatees like to swim up to the surface of the water in areas where there is sea grass. Manatees eat all kinds of plants in the sea, including sea grass. The sea grass around the manatee’s head when they eat could create a picture of long hair.

Manatees also have powerful tails that are very similar to the fish-like tail of a mermaid. The sailors probably watched manatees come up for air and then swim back below the surface, using their paddle-shaped tails. This would explain why the sailors thought mermaids had fish-like tails.
小题1:What are mermaids?
小题2:Where do manatees live?
小题3:Do manatees need to breathe air out of water?
小题4:What do manatees eat?
小题5:Why did the ancient sailors mistake manatees for mermaids?
