自行车——中国重要的交通工具
Bicycle—-an Important Means of Transport in China（1991．1）
（自行车——中国重要的交通工具）
1． 为什么自行车在中国这样普及。
2． 和汽车的比较。
3． 自行车在中国的前途。
这是一篇提纲作文。第一段，自行车在中国这样普及，是由于中国是个发展中国家，人口众多，经济还不是很发达。第二段，和汽车相比，自行车体积小容易存放；自行车不用燃料，不会带来污染和能源危机；中国人民的消费水平有限。第三段，自行车在中国的前途，目前自行车依然是主要的交通工具，但不久的将来，随着国家经济的发展，会有越来越多的人拥有汽车。但是，汽车绝不会完全替代自行车。

Bicycles, as a means of transport, are indispensable companions of most Chinese. Each Chinese family possesses at least one bicycle. China is therefore called “the Bicycle Kingdom”. The popularity of bicycles in China, I think, is mainly due to the economy of the country and its people. China, as one of the developing countries, has no financial potential to expand its roads and to manufacture so many cars to satisfy the need of so many Chinese.
Compared with cars, bicycles, however, have their own distinctive advantages. Firstly, they are very convenient. For their small size, they do not need special parking space. They can be parked almost everywhere. For their light weight, they can be carried upstairs and downstairs. Secondly, driven by man power, they don’t need fuel. Hence they have nothing to do with air pollution and energy crisis. Finally, as China is still a developing country, most people can afford a bicycle rather than a car.
With so many advantages, bicycles will remain to be an important means of transport in China in the many years to come. But I think with the rapid development of Chinese economy, more and more Chinese will own a car though cars will never completely substitute bicycles in the future.
