Do you have any hobbies? If students don't have any interest except school work，they may become boring people. And that can influence their studies.

    Studying without relaxing isn't good for health. ⑴We can't get good grades if we have bad health. We should make use of our free time .We should do something we like. Some people like singing, taking photos and drawing pictures. Other people prefer collecting stamps，reading or shopping. I have a few hobbies，but my favorite one is collecting stamps. ⑵I like it best because I learn a lot from stamps.

    Some people collect stamps because they can make money from the stamps. But I am just interested in collecting them and enjoy looking at them when I am free.

    ⑶Collecting stamps is becoming more and more popular around the world. I know an Australian boy and a French girl through the Internet. They all like collecting stamps. We show our stamps to each other online. That is so cool.

Nowadays, with the economic (经济的) and social (社会的)development, there are lots of means of transport for people to choose from. But each has both advantages and disadvantages. 

Because plane is the fastest vehicle (交通工具), some people prefer (更喜欢) to travel by air in order to save time. But it also costs the most. 

Taking trains costs not as much as taking planes and they carry the most among all of the vehicles. 

The ship also has a large carrying capacity (容量) and the price of a ticket is quite low, but it travels the slowest. So it is not a wise (明智的) choice for you to travel a long journey by ship. 

The bus is only suitable for a short-distance trip, and the price is rather low as well.
