重要交通工具：自行车

As it’s known to all, China is popular for its emperor of bicycles. This is because our country is still a developing country and few people can afford private cars. The demand for a means of transport is met by making millions of bicycles available.

Riding a bicycle has a lot of advantages over driving a car. First, it is a physical exercise to ride a bicycle. In contrast, sitting in the car, one tends to gain weight. Besides, it is much more economical to ride a bike than drive a car. On the one hand, the only fee a bike-rider has to pay is the annual tax. However, the annual fees for a car are costly. On the other hand, a bike needn't be equipped with a parking lot, but a car must. Most important of all, it is beneficial to the environment to ride a bicycle because the bike doesn't consume petrol; it is a pollution-free transport. In contrast, the exhaust released by the car is harmful to the environment.

Since China is a developing country with a large population, bicycles will still be the most popular means of transport in China for quite a long time. Most people will still ride bicycles to go to work or to school. The emperor country of bicycles will remain for at least dozens of years.

大家都知道，中国因其是自行车王国而倍受欢迎。这是由于我国仍然是一个发展中国家，以前很少人买得起私家车。对交通工具的需求通过制造数百万可供使用的自行车得以满足。

比起开车，自行车有很多优点。首先，骑自行车是一项身体锻炼。相反，坐在车里容易长胖。此外，骑自行车比开车更经济。一方面，骑自行车的人需要付的费用只是自行车的费用。但是，汽车的每年费用很昂贵。另一方面，自行车不需要配备停车位，而汽车必须要。最重要的是，骑自行车对环境有益，因为自行车不需要耗油，它是一种零污染的交通工具。相反，汽车排放的废气对环境有害。

由于中国是发展中国家，也是一个人口大国，很长一段时间内自行车在中国仍然是最受欢迎的交通工具。不少的人仍然会骑自行车去上班或者上学。自行车王国至少会保持好多年。
