May I have your attention?

We will visit the summer Palace on Wednesday, May 2nd. The Summer Palace is the largest well-kept royal park in China. In the park there is water and man-piled hills. There are some royal buildings and a gallery, too. I am sure you will be struck by its beautiful scenery. In the morning we will be free to visit the different places of the Palace and then we will have lunch in the fast-food restaurant. We will get back to the hotel at half past five. Please gather at the hotel gate at 6:10 on Wednesday morning. The buses will start at 6:30. It will take us about 45 minutes to get there .

Please be on time. Thank you.

Good morning, dear friends. Welcome to our school. Now please allow me to introduce you some of our school rules here. As high school students, firstly, we are expected to be neatly dressed when at school. Secondly, it must be made clear that we should never be late for class or leave school before it is over. The school is a place for us to live and study in, so we must keep it clean. Lastly, when you are walking on the road, please remember to keep to the right, and, if you want to go to school by bike, you must have a bicycle-permit.

Thanks.

Dear Andy,

I am glad to learn that you are coming to China and will stay at my home.

My parents and I are very pleased to have you with us. Now let me tell you what we have arranged for you. I know the school will organize a lot of things for you to do in the morning, but in the afternoon, I’ll show you around and take you to some places of interest. We’ll mostly stay at home in the evening watching TV, playing games, and meeting people. I’m sure we’ll have a wonderful time and enjoy each other’s company.

I’m looking forward very much to meeting you soon.

Yours sincerely,　　　

Li Hua

Dear Editor,

I’m writing to tell you about the discussion we’ve had about whether an entrance fee should be charged for parks.

Opinions are divided on the question. 60% of the students are against the idea of entrance fees. They believed a public park should be free of charge. People need a place where they can rest and enjoy themselves. Charging entrance fees will no doubt keep some people away. What is more, it will become necessary to build gates and walls, which will do harm to the appearance of a city.

On the other hand, 40% think that fees should be charged because you need money to pay gardeners and other workers and to buy plants and young trees. They suggest, however, fees should be charged low.

Yours truly,

　　　　　　　　　　　　　　　　　　　　　　　　　　　Li Hua

The summer holiday is coming. Our class have had a discussion about what to do during the holiday. Some are in favor of staying at home. They think it’s both convenient and comfortable. What’s more, they can save money for other purposes. But they will lose the chance of getting to know the outside world.

However, others prefer to go out for traveling since it can increase their knowledge and broaden their horizons. But they will spend more money and meet some difficulties while traveling.

In my opinion, it would be much better to stay at home, for I can do what I like, such as reading books, watching TV, and helping my parents with the housework.

　　　 Should students make friends on line? Some people say yes. The internet helps make many friends. Chatting on line, students can more freely express their feelings and opinions, and even get help with their foreign language studies.

　　　 Others, however, think students should not. They say making friends on line is a waste of time, which should be spent more meaningfully on study. Besides, some students get cheated on line.

　　　 It is my opinion that students should place their study, health and safety before other things. As for friendship, we can readily find it in our classmates and other people around us.

After that I went to No.62 Middle School of Dalian and graduated this summer. The main subjects I studied at school included Chinese, maths, English, physics, chemistry and computer. I like English and computer best and I am very good at them. Last year I won first prize in the school computer competition. In my spare time I enjoy listening to popular music and collecting stamps. My favourite sports are swimming in summer and skating in winter.

Dear Bob,

　I’m so glad to learn that you’re coming in September. I’ve found a place for you. It’s a small flat of 25 square meters, with a bedroom, a bathroom and a kitchen. In the bedroom there is a bed, a sofa, a desk and a chair. The rent is 500 yuan per month. The flat is in a building on Fangcao Street, which is not far from Jianxin Chinese School. Bus No.11 can take you straight to the school. In fact, it’s only one stop. Do you think you’d like it? If not, I can try and find another place for you. Just let me know.
