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.

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.

【小题1】 What can a dolphin use to make an eel come out of its hole?

A smile will tell people around you that you are a kind and friendly person. However, many people don’t smile because they think they ugly teeth. For example, one of my classmates, Mile, doesn’t have very nice teeth, so that is why he seldom opens his mouth. he even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others’ teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brush-ing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of then.
Smiling can help you to feel more confident and make other people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Katarina said that young children should laugh about 300 times a day, wile adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now!
