Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly , for example by dipping it in water , it will be very hard but also very brittle(脆)---that is , It will break easily. Metal that has been annealed is soft but does not break as easily . It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly , for a certain length of time. The longer the heated metal takes to cool slowly , the softer it becomes . Annealing can also be used on other materials, such as glass.

When I was eight years old, I had a big accident. I get scared even now when I think about that time. There were many people skating near my house, and seeing them skate so wonderfully, I couldn’t wait to have a try, just a piece of cake, I thought .

I went with a friend who was very skillful. He spent a long time teaching me how to skate , but I still didn’t learn much , which made him very angry. Finally , he left me and skated all around. I skated alone and soon got bored because I kept falling down so I took off my skates and just walked around on the ice in my shoes. It was cold and my feet were frozen.

Suddenly, I stepped on something that was not hard. What was it ? It was a weak place in the ice . When I stepped there, I sank under the ice. I thought that I was going to die, but I did my best to grab something to get out from under the ice. I would have climbed out myself by grabbing the edge of the ice, but at that time I was only a child of eight . I cried out.

Fortunately, someone helped me. He grabbed my arms and pulled me up. Those several minutes seemed a year to me. I thanked him. At that time, my friend came back. I was annoyed at him because he was supposed to take care of me, but he didn’t. He was embarrassed. When I took a taxi home, the taxi driver was surprised and asked what had happened. I didn’t want to say anything because I was tired and scared. Since then, I have never touched skating.

根據(jù)短文內(nèi)容,從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

  1  All the teenagers we chose said they had computers at home. We asked them how much time they spent on their computers in an average week, but we were most interested in what they used their computers for. The average time spent on a computer in a week was about 12 hours, with the highest user averaging 32 hours and the lowest user only 5 hours.   2    3  Fourteen teenagers told us they did some word processing at home, but not very much. Only 2 of them said that computers helped them with their studies, while 8 of them told us they kept addresses and telephone numbers on their computers or used them as diaries. Only 3 of them said they were learning to program computers, and nobody looked up information (other than their address lists).   4 

The results indicate quite clearly that computers are seen by most young people as little more than game machines.   5  It seems to us that, although computers are common in the homes of teenagers, they have not yet become useful tools in everyday life.

A.There no big difference between boys and girls.

B.All of the teenagers questioned said they regularly used to play games.

We usually prefer to do things the way we considered to be the best. However, it is important to listen to those who love us and want to give us an advice when we have serious problems in our lives. Parents have gained some life experiences and they know what to act in different situations. That’s why we should ask them for help first when they have problems. Therefore, there are moments when we avoid them and don’t want to follow them. With time passed, my brother as well as I have realized that our parents are right.
