6. May I have your attention, please? As you know, our class will have a talk show on environment protection with Class One on May 4th. Before it takes place, we will invite Dr. Lil from Qinghua University to give us a talk on the environment problem and he will also tell us about the improvement in environment protection in recent years in Beijing. The report will begin at 2:00 pm on Wednesday, April 30th in the auditorium on the third floor in the classroom building. I’m sure we can get enough information from his talk to make good preparations for the coming talk show. Everyone should be there on time, then listen to the report and make full notes at the same time. By the way, we will have a discussion after the report. That’s all. Thank you.

4.　 Yesterday I paid a visit to a model high school, together with my friend. It’s very big with a beautiful fountain in the center of the schoolyard. We started our visit from the main building. First we went to the lab building where some students were doing experiments. Then we entered the lecture hall behind the lab building and saw many students listening to a lecture given by a professor. Opposite to the lecture hall was the art center. There we watched groups of students playing musical instruments. Finally we arrived at the playground at the far back of the school. Some boys were having a football game, which was so exciting that we couldn’t help cheering for them. It was really an impressive visit. 5.　　　　　　　　　　　　　　　 An Announcement Boys and girls, 　 May I have (take) your attention, please. There will be a lecture at half past three on Friday afternoon. It’s about “Information and English Study”. And it will be given by Mr Li Ping who is a famous teacher from the English Department. There’s sure to be something instructive and interesting. We can get more information from it, I think. And it will improve our English studies to a new stage. Anyone who wants to attend it can come to Room 206. Take notes and have a discussion after it. Please come here on time. 　 That’s all.

1. Dear Tom, It’s great to receive your email. Now I’d like to tell you something that took place in my school yesterday. In the afternoon we held a growing-up ceremony for our coming 18-year-old birthday. At first we made an oath that as grown-ups we should have a sense of duty for our society form now on. Then we showed our thanks to our parents who had gone through hardships to bring us up and teachers who have been educating us patiently. And our teachers also gave us cards expressing their good wishes to us. Finally, we put on wonderful performances, singing and dancing. We learned a lot from the activity. I think it’s very important for us. I will remember the day in my life. Yours, Li Hua 2. Monday　　　　　　 May 18, 2002　　　　　　　　　　　 Fine 　　 This morning our teacher told us something about the Hope Project in class. She said, “Now in the countryside many children still can’t go to school because of poverty. Can you help them?” 　　 After school, I went home. When I entered my room, I saw the little box in which I keep my pocket money. Though I wanted to buy a pocket recorder, I decided to send my money to the children who are eager to go to school. I began to write a letter to them at once. After finishing writing it, I went to the post office and posted all my pocket money with the letter together. 　　 I felt very happy today because I’ve done a good deed. 3.　 Last Sunday my classmates, Lin Tao, and I went to the bookstore. At a counter we noticed a foreigner was asking a man for help, but the man didn’t know a word of English. So we went up to him and offered help. After knowing what he really wanted, we took him to the counter where tapes and disks of Chinese folk music are sold and gave him some advice on which to choose. With our help, the foreign guest got some music tapes. He gave his hearty thanks to us and left. Though it took us some time to help him, we were happy anyway.

　　 喂！大家好，我是二氧化碳灭火器，是灭火器大家庭中的一员。我通常被装在红色的钢瓶里，别看这钢瓶小，可是在危急的火场中，我的作用可不小呢！由我来灭火不会因留下任何痕迹而使物体损坏，因此我可以用来扑灭图书、档案、贵重设备等。

　　 那你知道我们二氧化碳是怎样被装进灭火器中的吗？聪明的人类早已经了解了构成物质的分子、原子等微小粒子间有间隔，构成我们二氧化碳气体的分子间也是这样的。为了能把更多的我们装进钢瓶中，人们就采取压缩气体体积的方法，给我们加压，使我们分子之间的间隔变小，这样我们就变成了分子之间更加紧密的液态二氧化碳。这样，一瓶二氧化碳灭火器就做好了。你看，是不是很神奇呀？

当火灾发生时，人们只要拔掉安全阀，按压阀门，我们马上就从钢瓶中争先恐后的跃出身出来，于是就有变成了气态，由于二氧化碳有不助燃的化学性质，熊熊大火很快就被灭掉了。但同学们一定要注意，使用时，手一定要先握在钢瓶的木柄上。因为我们液态二氧化碳气化时要吸收大量的热，使灭火器附近温度很低。否则，会把手冻僵。

听了我的自述，同学们明白二氧化碳灭火器的工作原理了吗？相信我的自述对你们会大有帮助的。
