Penguins are lovely animals. Most people like them. But now as many as 10 of the 17 kinds of penguins are in danger of disappearing. The number of penguins has decreased by ( 減少了) 30% since 1987.
Penguins are black and white birds that live in the southern part of the world. They are common in the Antarctic Continent (南極大陸) ,New Zealand, Australia and South America. Many live near cold waters (水域). But some live near warm waters in Galapagos Islands. Penguins  cannot fly, but  they are fine swimmers. The shape of their body helps them to survive. Penguins eat fish and krill  (磷蝦). They have short wings that help them to dive up to 900 feet to catch larger fish. They can swim 10-15 kilometers an hour which lets them protect themselves. They also have lots of body oil that helps in keeping them dry in the water.
The warming of the earth is the reason for the decrease in the number of penguins. The hotter and hotter air has caused ocean waters to become warmer. Higher water temperature has decreased the fish and krill. Some years later these birds are completely unable to reproduce. And many adult penguins die of hunger.
Too much fishing, exploration for oil and oil leaks (泄漏) also make penguins be in danger. Poisonous things in ocean waters are another danger. Penguins also have their enemies, including sharks, seals and sea lions.

Computers are very important to modern life. Many people think that in the future computers will be used a lot in everyday’s life. It is thought that we won’t have to go shopping because we will be able to get most things which are sold in shops on the Internet. There will be fewer books because we will be able to get all texts from computers. The Internet will be used to play games, see films and buy food. Most telephone calls will be made by computers, too.
Some people are glad about these new ways of shopping and communicating(交際). Others do not think that computers will replace(代替) our old ways.
Let’s take books for example. Some people think that one day we won’t read books made of paper. Instead, we will buy and read books using computers. We will read texts on small pocket computers. The computers will keep many different books in them at the same time. We won’t need to turn lots of pages and paper will be saved. Computerized books will be used more and more.
Is Internet shopping such a pleasure as going to the shop? Many people say it is not. It is a pleasure to go into shops and look at things you want to buy. It is also unlikely(不大可能) that many people will want to read large texts on our computers. Because paper books will perhaps be more friendly. Maybe computers won’t change these two habits(習(xí)慣).

>【題文】Experts(專家) say that students usually need eight to ten hours’ sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy put up one finger (手指) with his eyes still closed, begging(請求) for one more minute to sleep. Like thousands of students “ early birds” in China, he has to get up before six every morning.
A report shows that without a good night’s sleep, students seem to be weaker (虛弱) than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.
Experts have ever said that the students should develop good study habits. So some clever students never study late, they are able to work well in class.
