Nowadays more and more Chinese go to work with bicycle, leaving their cars at home. Why are so many people riding bicycles to work? They have different reason for it.

First, bicycles do not use up any fuel. Therefore, they cost less than other means of transport. Besides, bicycles do not need many space on the road, and it is easily to find a place for it. And everybody knows that riding a bicycle is healthy sport.

When people drive their cars to work or shop, they lost the chance to exercise, but the waste gas from the cars will pollute the air. And moreover, people feel annoying when looking for a parking lot in the busy city center. So I prefer riding a bicycle to drive a car.

We are looking forward to a cleaner and better environment by changing our life style.

Smart phones had become part of our daily life. No matter who we are, we can see people busy play with their smart phones. Smart phones benefit them. They help us escape the pressures of life and get informations. However, if we spend too much time on them, we won’t have time to contact face to face our friends and family. And our life, study and work will hurt. In my view, we should limit to our using smart phones except for a purpose of learning.
