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。

Learning to study is not difficult. The first thing to remember is that you must be willing to learn. It doesn't mean that you must always like the subject. It does mean, however, that you must be willing to learn whatever is necessary. Try to understand why it is important and how it will help you now and later. Knowing mathematical facts will be useful in your whole life. Knowing how to spell words makes any kind of writing easier. Sometimes the subject that you think is going to be uninteresting and it will be attractive when you began to work on it. Learning things can be fun if you can try your best.

Here’s some advice for you: have a certain time each day and a quiet place with good lighting for study, so that you can concentrate on you study without interruptions. Have everything ready before you sit down to study, a dictionary, paper, a pen and books. Be sure you understand what you should learn before you start. Read carefully and pay special attention to the most important things. When memorizing, find out the main parts and then recite the whole thing. Check your homework after you finish it. Never forget the importance of review and preview.
