Dear friends，
Coaching books are now very popular among middle school
students, and they are playing an important role in our study.
----
幻灯片 34 Coaching books can help us review, summarize and
consolidate what we have learned, and they can also guide us how
to learn in future.Good coaching books are just like good teachers,
which are a great help to us learning.
However, we cannot depend too much on coaching books,
because the best way of learning is to learn by ourselves.What's
more, some coaching books are of poor quality, so we need to
choose and judge by ourselves.
That's all.Thank you!
