To write an argumentative essay for the college entrance examination, you need to follow the following steps:

1. Make your argument clear: You need to make your argument clear before you start writing. This is the core of your article, and all arguments and evidence should revolve around this argument.

2. Collect information: You need to collect enough information to support your argument. These materials can be facts, data, examples, etc.

3. Outline: After collecting enough information, you need to outline your main arguments and evidence. This will help you organize your ideas and ensure that your article has a clear structure.

4. Writing: When writing, you need to express your opinions clearly and accurately, and support your opinions with strong arguments and evidence. Your article should have a clear introduction, body and conclusion.

5. Revision: After completing the first draft, you need to revise your article. Check grammar, spelling and punctuation to make sure your article is logical and well-argued.

6. refute objections: in your article, you also need to consider possible objections and prepare rebuttal arguments in advance. This will make your article more convincing.

7. Time management: There is usually a strict word limit for argumentative papers in the college entrance examination, so you need to manage your time effectively to ensure that you have enough time to complete your first draft and revision.

8. Stay calm: You may feel nervous during the exam, but you need to stay calm and concentrate on your article, not your nervousness.
