Reference Books(参考书)
Nowadays both of teachers and students use reference books during their studies, and there are many kinds of reference books in the book market. So how to use them becomes a very important problem.
First of all, some reference books might make the students inattentive(不专心的) in class. With reference books, many students may think that they know what the teacher is going to talk about. So they may not listen to the teacher in class at all. Secondly, some students rely on the reference books too much, they may not prefer to working out problems by themselves. Thirdly, there are some reference books with many mistakes, which might mislead(误导) the students.
Therefore, we should be careful in selecting and using reference books. Besides, reference books are just an assistant, so we shouldn't rely on them too much. Only in this way can we make full use of reference books.
