Do you like crocodiles (鱷魚) ? Do you know anything about crocodiles? Crocodiles appeared about two hundred million years ago. They once lived on the earth together with dinosaurs.

Crocodiles only live where it is wet and hot. They spent most of their time lying around in the mud (泥) or the rivers. The crocodiles’ long tails are used when the animals are swimming. It can be swung (搖擺) with great speed and force (武力). One blow will knock down a man or even a big animal at once. Crocodiles are very well protected against their enemies by the hard bone plates (骨板) which cover most of their bodies, but because of the way their neck are formed, they can only see in front of themselves. With their rows of terrible sharp teeth, they catch food, which may be a fish, an animal or even a careless man, and then hold it below the water until it drowns (淹死). Crocodiles lay their eggs and leave them under leaves or sand. Baby crocodiles have special sharp teeth with which to break their way out of the shells (殼) on their own. Crocodiles were once all over the world. But in the past 50 years, the number of crocodiles has gone down rapidly because of humans. The long-nosed crocodile is shy and because of this, the people of West Africa sometimes catch it for food. But more people hunt them for expensive crocodile leather. Now this kind of ancient animal has to depend on humans to live. Isn’t that terrible?

任務(wù)型閱讀請閱讀下面短文，在短文后表格中的空白處填上適當(dāng)?shù)膯卧~（注意：每空1個(gè)單詞）。

If we agree that education is used to prepare us for life, then there is very little time to waste. So, while we can, we should teach children something really useful. Here is what our school should teach．

Politeness is a mark of civilization(文明). The sooner children learn this, the better. In any case, a lot can be achieved by a smile and good manners. Like it or not, our adults work hard for money, but we don't make an effort to teach children how to manage it. So our schools have a duty to teach them this ability from the beginning．

We're likely to accept something we are told, but that's not what educated people do. Educated people are reasonable and they look at facts. If our schools teach nothing else, they should at least teach critical(批判性的) thinking．

Children should learn to take care of their health. They should know that if they eat junk food, they will become fat and unhealthy. They should be very clear about what happens to their bodies when they drink or smoke．

All of us are part of society. We have rights and duties. We should understand what they are. We have to know a little bit of history and geography, because we need to have an environment in which to communicate with the people around us.

In a word, our schools should spend every moment they have telling this to our children: “This is life, this is what you are going to face, and this is how you deal with it."
