Last summer I had a unusual experience. It was raining hardly. Because of this the river near my town raised and flooded some of the rice fields. The villagers, included me, went to the dam to make them strong. The soldiers also come to help us. We fought for three days. At last the dam saved and our village was protected from the flood. Though I became very tired after I returned home, but I was very happy. I learned many from the villagers and the soldier. Now we are looking forward to have a stronger dam.

Dear Tom,
I'm very glad in receive your letter. And it's pleasure to tell you something about how I spent the National Day holiday.
First, I have a good rest. Of course, it took me two days that to stay with my grandparents who live in the countryside. I helped them do any housework and told them what has happened to me and my friends. What's more, I had a trip with their friends to appreciate the beauty of nature but breathe fresh air. How did you do in your summer holiday? I'm looking forward to hear from you.
Best wishes!

I'd like to tell you something more about the problem of pollution we
are facing to. As we know, the factory besides our school gives off heavy
smoke all day long. Very loud voices hurt our ears. Rubbish and waste
are thrown here or there. It also sends out polluting water and poisonous
gas. All this has made a great harm to the health and study of the teachers
and students. But with time goes on, a little has been done to change the
situation. I don't think we could study well unless the problem is solved.
We do hope you'll help and support us.

Boys and girls, attention, please! I have anything to say. It’s a good news that our school is going to hold a party on Saturday evening, when is to welcome our Canadian friends. The party will be interested. You can dance, listen to music, sing songs and playing games. Would you like to bring a small gift with you? Then you can send to your new foreign friend. Please write a few word that can express your best wishes. Anyone who want to attend the party can go to the great hall in the second floor. Everyone is welcome.
I hope everyone will have a wonderfully time. That’s all. Thank you!
I’m writing to request a valuable chance to be one of the host family for the British students. We have a large and clean house, where lies in a beautiful area of the city. I’m good at English and my parents are all professors of English, so I’m sure we won’t have difficult communicating with English speakers. My father is a excellent driver and we will very glad to show foreign students around some nearby places of interest in our own car. Last month we were received two American students. We have a great time. However, my mother cooks well, so the students will be able to enjoy delicious Chinese food. I would greatly appreciate if I could have the chance to make friends with them.
Looking forward to your reply.
