【简答题】
Nowadays, there is a new trend among college students. Many of them have moved out to live outside the campus, some for love, and some for the convenience of life or study. They want to live alone and always declare that they need their own room. Should the students live in the dormitory or live alone? What's your opinion about this? Write an article of about 400 words on this and supply a title for your article. In the first part of your writing you should present your thesis statement, and in the second pan you should support the thesis statement with appropriate details. In the last part you should bring what you have written to a natural conclusion or a summary. Marks will be awarded for content, organization, grammar and appropriateness. Failure to follow the above instructions may result in a loss of marks. Write your composition on ANSWER SHEET FOUR.
