The bicycle is a relatively recent invention. It is by far the most economical and environmentally friendly mechanical mode of transport yet invented. Describe how the illustrated two-wheeled bicycle below functions, and be sure to mention in your description the machine’s environmentally-friendly feature. You should write no fewer than 120 words.
选项
答案
As we know, bicycle is cheap, easy to operate, and convenient. Surely, it is one of the most useful transportations man has ever invented.
As we can see in the picture, the saddle is designed to be of triangular shape, which makes the rider more comfortable. The pedals can revolve flexibly in response to the feet. The pedals give force to the chain which accordingly drives the wheel. As is illustrated, the original force for the bicycle to move is human’s power instead of fuel or other resources, therefore, it is resource-saving and free of pollution. When you need to slow down, just put on the brake.
From the above analysis, we can see that the bicycle is not only a useful transportation, but also an excellent fitness equipment. It should always be our best choice.
