foreign university. The most serious problem is the language barrier. Most of the students who are ready to go abroad do not adequate knowledge of the language spoken there. As a result， on arriving there， they will find it difficult to understand what the instructors are saying. Besides， for lack of knowledge of the customs and way of life of the local people， they may run into trouble in dealing with various situations. Therefore， misunderstandings often arise. Furthermore， the cost of living is much higher than that in our country， so most students have to find part-tine jobs in order to help support themselves. Faced with these difficulties， many students find themselves unable to pay full attention to their studies and some students may even fail in their courses and learn little.
Therefore， given an opportunity to attend a school abroad， one must consider both sides of the factors carefully before making up his mind. On the whole， it is a good thing to go and study abroad particularly when the subject is very weak or not available in our country. But on the other hand， one must not lose sight of the disadvantages.
（七）Is the Expansion of Enrollment a Good Thing？
Many colleges and universities have expanded their enrollment since 1998. The reasons for the expansion are as follows. Firstly， they want to keep up with the need of the job market to produce more qualified people to take up the jobs. Secondly， the expansion has entitled many high school graduates to the right of receiving higher education. Last but not least， it can raise the intellectual standards of our nation.
However， studies show that the trend to expand has brought about many problems. For instance， the teaching facilities and accommodation capacities of many colleges and universities are limited and are unable to meet the demand of an ever-increasing number of the newly enrolled students. On the other hand， the average quality of the freshmen is declining. In the long run， hunting for a job will be a tough thing for the graduates and that will inevitably exert much pressure on the prospects of employment.
In spite of all this， I am still confident that the expansion of enrollment is of great benefit to our society and is a good thing. With the development of our national economy， the problem as mentioned above will be solved if proper measures are taken.
Don\'t Hesitate to Say “No”
To help those who are in need is always regarded as a traditional Chinese moral. However people have to know well what the need is before the help is offered. When the need is just for some minority\'s benefit and against most people\'s interests， or when it is immoral or unlawful， people should not hesitate to say No. Otherwise they will put themselves into trouble.
