建议:先在草稿纸上练习，找找手感，再答卷。

Dear Simon,

    I have received your letter about asking me for the advice about learning English. Now I'd like to tell you how you should learn English.

    First of all, you should often read English aloud and try to learn something important by heart, which helps you to remember them easily and form a good habit of thinking in English. Besides, you should listen a lot and communicate with others in English. In this way, you will improve both your listening ability and your spoken English as well. What's more, you should keep a diary in English every day and your written English will become better and better.

    I hope what I've said is useful to you. I'm looking forward to your good news.

    Best wishes.

Yours truly,

Mary
