Last weekend, Dave, Bob, Alice and Ann had a trip on the island(岛) not far from their houses. Dave rode his bike to the river with his guitar at eight first. Then Alice got there. She took No. 5 bus to go there. But why didn’t Bob and Ann come? They decided to meet at eight. At ten past eight, Ann came. She said, “I’m sorry I’m late. I have to walk here because my bike doesn’t work.” Ann could play the violin very well. She took it with her. Another twenty minutes passed. Bob arrived there. “Bob, you’re late,” Dave said.

“Hmm...On my way, I helped a boy find his parents,” said Bob. “Oh, Bob, you’re great. You’re a good boy,” all the other children said.

The boat ride took them about twenty minutes. At twenty to nine, they came to a boat and took the boat to the island. Wow, the island was green everywhere. It’s really great. They did something interesting there. First they enjoyed the wonderful sights(景色). Then, they had some fruit and drinks. At last, they had a show. Dave played the guitar. Ann played the violin. Alice danced and Bob sang. They had a fun time.

We sometimes call the lion “the king of the jungle (丛林之王) ”, because it is stronger and more dangerous than other animals.     60     It is the highest animal in the land food chain (链).

In the sea animals, the shark (鲨鱼) is one of the animals at the top of the food chain. It can swim faster than most other sea animals.     61    

What is at the top of the world’s food chain? People are!     62     We could not run faster than cheetahs (猎豹), but we invented cars and now we can move the fastest. We could not fight better than lions, but we invented guns (枪). Now we can hunt the best.

People’s inventions are clever, but they can be dangerous too. For example, people invented lactones (内酯), but now they make the air and rivers dirty.     63     Dirty rivers kill fish. The bears cannot eat the fish and they die. If we kill one part of the food chain, other parts also die. Remember that we are also a part of the food chain, so we are in danger, too!     64     We should and we could do something for the world!

My name is Susan. I am outgoing. I like to have friends who are similar to me. Both my best friend Linda and I like traveling. We went to Italy with our families last summer vacation. We stayed there for a month. Next year we want to go to Paris.

My name is Mary. I like to have friends who are different from me. My best friend Betty is shorter and more outgoing than me. I am quiet and I like reading very much. Betty likes sports and she plays ping-pong well.

I am Peter. I like to have friends who are like me. It can be very helpful. I a little quiet and my good friend Rick is quiet, too. Sometimes I don’t know what to do with my problems and he can tell me what I should do, because he knows about me better than people who are different from me.

I’m Bill. I have both kinds of friends. I think it is important. That makes my life more interesting.

This term will be over. When I look back, I find that
