Dolphins are our friends. They can use tools ...

Dolphins are our friends. They can use tools to solve problems although they don't have hands.   For example, scientists have ever found that a dolphin can make a shy eel(鳗鱼) come out of its hole with a dead fish.

Dolphins use different sounds to exchange information with each other. Scientists in Hawaii have developed a sign language to give instructions to dolphins, and the results are amazing. They find that dolphins not only understand the meaning of individual (个别的) words, but also understand the importance of word order in a sentence.

Most animals enjoy playing — but dolphins seem to like making their games as challenging as possible. On a beautiful day in 1997, scientists at a beach watched a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins came up to the dog and then started throwing it into the air. The dog seemed to enjoy the "game" and continued playing with the dolphins for more than an hour.

Dolphins live in a very different world from ours, but they are very good at our "IQ tests” . For example, they will jump out of the water when they hear a whistle (口哨) noise. They do this because they will get a fish as a prize.

There is still much to learn about these cute problem-solvers, but it is certain that watching a dolphin show is fun.

How to Protect Animals

根据材料内容，回答下列问题。

Animals are our best friends. They are important to us. They live together with us on the earth. If there are no animals , we will not live, either. So we should take good care of them to help us protect our homes. Then how to protect the animals?

First of all, we should understand the importance of protecting wild animals. As we know, animals are an important source(来源) of food. Every animal has its place in the balance(平衡) of nature. If we destroy(毁坏) a kind of animal, we will have many other problems very soon. For example, when farmers kill a large number of hawks(鹰), the mice will destroy farmers’ stores of rice. Because hawks eat mice. Without hawks, the number of mice is becoming more and more.

Then, let people know how to protect animals. First, ask people to stop killing wild animals and keep the balance of nature. Second, we should protect animals’ habitat. If we see other people destroy animal homes, we should stop this behavior(行为).

Protecting wild animals is the duty(责任) of each of us. Let us protect animals together!

When our friends come to visit us in the evening, they spend their time telling us they are in a hurry or looking at their watches always. It isn’t that our friends are all very busy. It is just because we haven’t a TV set. They think that we are very strange.

But what do you do in the evening? They always ask. The answer is very simple. Both my wife and I have hobbies. We certainly don’t spend our evenings staring at the walls. My wife enjoys cooking and painting and often has evening classes for foreign languages. This is very useful because we often go to other countries for our holidays. I collect stamps and I am always busy with my collection. Both of us enjoy listening to music and playing chess together.

Sometimes there is power cut and the house is dark. We are not worried because we can just light candles and chat with each other about what we did before. Our friends are upset at that time because they don’t know what to do without a TV set. On such evenings, our house is always full because my friends all come to us. They all have a good time. Instead of sitting in silence in front of the television, everybody talks and plays games.

Dolphins are not fish. They are mammals(哺乳动物). They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain is as big as men’s and they live a long life---at least 20 or 30 years.

Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and help them find food. They do not use their ears to receive sounds, but use the jaw —the lower part of the mouth.

It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903, Jack met all the ships and boats in the area and showed them the way. In 1903 a passenger on a boat with the name of The Penguin shot(拍照) a long time in the area. Jack guided the boat The Penguin until the passenger finished.

Today, some people still kill dolphins, but many countries in the world now protect them. Dolphins are humans’ friends. Let’s all be nice to them.
