Smoke
This is a funny and instructive picture. In the picture, a young man is smoking happily in a factory when he sees a sign which means “No smoking” on the wall. But he finds that the factory is giving off large quantities of heavy smoke which makes him feel very puzzled, “Why does the factory forbid people to smoke while the factory itself emits so much poisonous smoke?”
Nowadays, many factories know the danger of smoking to themselves and don’t allow people smoking in the factory. However, they don’t pay any attention to the danger that they cause to the whole society. And they let out lots of polluted smoke which does great harm to our environment.
In my opinion, we could live without most of the industrial products, but we could not survive without nature! Therefore, something must be done to prevent the pollution caused by all factories!

Dear Bob,
It’s very kind of you to write me and let me know about our beautiful city. Now I’d like to tell you something about my hometown Jiangcheng.
The city stands on the bank of the Changjiang river. It is a beautiful place for people to live in. Its economy has been developing rapidly in the past ten years. New factories, houses, and roads have been built. More schools and hospitals are available for its people. However, there are still some problems, such as water and air pollution and heavy traffic in rush hours. In my opinion, Jiangcheng should develop its economy scientifically. I would also think that the growth of its population should be brought under control so that we’ll have a better hometown in future.

Planning Is Good, But Doing Is Better
Planning is good as it decides in detail how we do what we want to do. However, a plan can bear no fruit without being actually carried out.
My experience in the English speech contest last October is a case in point. A month before the event, I spent hours working out a schedule outlining my goals and practical steps. After that, I set out to read widely for an inspiring topic, wrote a speech, and practiced its delivery in beautiful pronunciation with good public speech skills. I finally came out of the contest as the first prize winner.
I know how I achieved my success. It came from good planning and better doing combined.

1998 National English Summer Camp for Middle School Students
As a lucky student, I attended the 1998 NESCMSS held in the beautiful seaside city of Yantai from July 25 to 30, which was sponsored by the English Coaching Paper Office. Over 100 students all over the country and 30 English teaching experts from home and abroad took part in the activity. All the campers were required to speak English. During the four days, a series of English activities were held including the Second National English Debate for Middle School Students and the Third National English Speech Competition for Middle School Students. We also visited some places of interest. A colourful English evening was held on July 29. The camp provided us with a valuable opportunity to speak English, make friends and exchange learning experience. I found my English much improved at the end of the camp. Never in my life shall I forget the impressive days in Yantai.
