With the development of science and technology, mobile telephone becomes more and more popular. If you go to a college campus, you will find an increasing number of students begin to use mobile telephones.
   On the one hand, mobile telephones is good to the students. It enables them to keep in touch with their friends and family more conveniently and quickly. On the other hand, mobile telephone has a negative effect on the students. It will cost them more money than before, and will distract them from their study, especially when it rings in class or in the library.
   In my opinion, it is not good for the students on campus to use mobile telephone. Since the students' main purpose on campus is to study, they should pay much attention to their study. If they want to use mobile telephone, they can use it after graduation.

   When it comes to where to go after graduation, the opinions vary from one student to another. Some students prefer to go back to their hometowns, while others choose to go to different towns or cities. Every student has his own consideration for his preference. As for me, I will go back and live in my home city after graduation. I have made this decision for the following reasons.
   Firstly, though my home town is not a very big one, it has great development space. With the building of more factories and corporations, I will have many opportunities to bring my abilities and skills into full play. Secondly, I want to go back home to look after my parents since I am their only child. Thirdly, the environment and people in my home city are familiar to me. Thus I needn't waste time and energy to adapt myself to strange people and things.
   In short, my decision is based on a careful consideration. Maybe there are more chances for development in big cities like Beijing and Shanghai, but for the moment, my home city is my sensible choice.

   There are some people in this world who are born to take care of things. These people might look after the younger children in a neighborhood, volunteer to organize a school activity, or manage projects at work.
   While being responsible seems like a positive thing, it has its disadvantages. For example, some people feel responsible for everything and everyone and may easily get stressed-out as a result. Another disadvantage is that some people end up doing more than their fair share of the work, without any acknowledgement from others.
   Despite this, being responsible is something we should all strive to do. Not only will it help to improve our personal life, but it can also help us climb the career ladder as well.

   It is almost known to all that smoking is bad for people's health. Many years ago, scientists found that smoking can lead to a lot of diseases such as heart disease, stomach trouble, and even lung cancer. What's more, smoking is harmful not only to smokers themselves but also to other people around them, especially to women and children.
   Still, many people find it difficult to stop smoking. For them, giving up smoke is impossible. First, they are so addicted to it that they can't help smoking at any time. Secondly, they are always find excuses for their bad habit such as to be relaxing, to relieve tiredness, and so on.
   Measures have been taken to help people keep away from the harm of smoking.  First of all, many responsible manufacturers have printed a warning: "Smoking is harmful to your health." Secondly, smoking has been banned in many public places. Thirdly, the government is making laws to forbid some ads on TV or newspaper to avoid its negative effects.

   It is necessary for college students to know the society. In school, we only obtain knowledge from books, which, sometimes, is different from real life experience. Only through practice, can we modify our ways in study in order to serve society better after graduation. What's more, we can gain abilities in organization and management in practice.
   There are many ways for us to know the society. For example, we can learn a lot through watching TV, listening to the radio, reading newspapers and so on. Also we can know the society through serving it, such as being a social volunteer to offer help to the disabled.
   Besides the ways mentioned above, I take an active part in some social activities. For example, I have been a private teacher in my spare time and taken a part-time job in the holiday. In this way, I think I can better fit society in future.
