It has been nearly 3 months since I came to study in this new senior middle school. I am getting on quite well with my fellow students, my teachers and my studies as well. What worries me a bit is that all the subjects we are learning here are much more difficult than those we learned in junior middle school. It seems as if my classmates are all ahead of me. I think I must work hard not to be left behind. To my relief, I find all my teachers kind and my classmates friendly to me. They are really helpful! I am sure I will make great progress in my studies with the help of all my teachers and classmates.Looking forward to hearing from you soon.Yours truly,Li Hua听力材料Text 1W: Would you like to study with us in the library?M: I’d rather study at home.Text 2W: Did the flight for Hong Kong leave ten minutes ago?M: That’s right. It’s now a quarter after eleven.Text 3W: You know. I’m going to cook dinner with some friends on Thanksgiving. We’re going to make fish soup.M: Hmm. That’s unusual. We always have turkey, ham and mashed potatoes.Text 4W: Excuse me, but did you see a six-year-old boy with a red hat pass by just now? My son...my son...M: No, madam. I was reading a newspaper; I think you should call the police for help.Text 5M: How about my fish?W: It couldn’t be better. You’re really a good cook.Text 6W: I think my wallet was stolen, sir.M: Do you have any reason to believe that your wallet was stolen?W: Yes, I left it on the table half an hour ago, but when I came back from the restroom, it was gone.M: Are you sure you left your wallet on the table?W: Of course, sir. I planned to pay the bill before I went to the restroom.M: Is this your wallet? One of my waiters found it in the restroom.W: Yes, it is. I must have left it there and I forgot. Sorry.Text 7W: How important are friends to you, Bill?M: That’s a strange question for this setting. D on’t you think so?W: Well, the teacher hasn’t come in yet, class hasn’t begun, and I was just wondering about it. So, what do you think about friends?M: I’ve never regarded them as particularly important.W: Why is that?M: Perhaps that’s because I come from a big family — two brothers and three sisters, and lots of cousins.That’s what’s really important to me. What about you?W: My situation, you know, is different, so I have different ideas. To me friendship is the most important thing in life. It’s more important than even love.M: Do you really think so ?W: You see, if you love someone, you can always fall out of love again, and that can lead to a lot of hurt feelings. But a good friend is a friend for life.Text 8M: Hey, Ellen, how are you?W: I’m fine, Bob.

As she was very old and in poor health, she had great trouble walking even when things were fine. With her house on fire all around her, she was unable to go anywhere. The smoke made her choke. The fire soon spread all over the house, so she would have died without quick rescue. Firefighters arrived at the house before long and searched through the house. But unfortunately they didn’t find her, so they began to try to put out the fire. Just then a man dressed like Father Christmas was passing by, and he heard the old lady coughing badly in the house. At once he threw away all the gifts which he would give to poor families and rushed into the burning house. After a while he was seen to rush out with the old lady on his back. First he carried her to safety, and then he managed to take her to the nearest hospital. In the end, the old lady was saved.。
