阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

Increased College Enrollment(入学)

In recent years, there is a steady increase in college enrollment. To many high-school students, it's definitely good news,for they would have better chance of receiving higher education.

You don't have to look very far to find out the advantages of the increased college enrollment. For one thing, it lessens the worries of both high school graduates and their parents. Besides,increased college enrollment can contribute to raise the educational level of our nation. What's more, increased college enrollment can provide more students with specialized knowledge, thus serving our development in a positive way.

On the other hand, we can not deny that there are some potential problems about increased college enrollment. To begin with, with the increased number of students, the shortage of teaching staff and facilities becomes clearly seen. Worst of all, increased college enrollment leads to increased competition in the job market.

It's not an easy task to tell whether the tendency should be encouraged. As to me, it's laudable to grant more students higher education. But a college degree is by no means a guarantee for a better job or future. To cast a promising career, we need a lot more abilities which we can not learn from college.
