Dear Wang Nan:
It seems that you have not been in a good mood since you entered Senior Three. You have to bear quite a high pressure from a lot of aspects. The pressure comes from our parents, our friends, our classmates, our teachers and, you know, even from the studies themselves. The high pressure makes us painful, sorrowful and sometimes even disheartened. Where is the way out? And where is the hope? In a lonely night, we often ask ourselves these questions.
We are now facing the College Entrance Examinations for all the graduates from the senior schools. We are all now waiting for the day which draws near and near. We have no choice but to face it. There is much truth in the famous Chinese saying which goes like this: No pains, no gains! All we have to do is to encourage ourselves to fight to the end because we have already struggled for nearly 12 years. I always believe fighting is life.
Trust yourself and you are always the best.
Yours
Li Hua

Dear Wang Nan,
I know you are feeling annoyed these days because you are not able to communicate with others effectively. It is my pleasure to offer you some advice on it.
As a saying goes, every man has his faults. I notice some people around us are also not good at communication. So you don’t have to worry too much about it. Of course, good communication is of great importance for us to create a pleasant relationship with others, which can not only be helpful to our study but also increase our chance of success. That is why I would like to make a few suggestions to you.
First of all, be honest and frank to those whom you talk to so as to be understood easily by others. Second, be aware of what you want to say and express yourself clearly. What’s more, you’d better try to understand others when they talk so that you can exchange ideas with them freely.
I hope my advice will be of great help to you.
All the best.
Yours,
Li Hua

解题思路：判断两个相关联的量之间成什么比例，就看这两个量是对应的比值一定，还是对应的乘积一定；如果是比值一定，就成正比例；如果是乘积一定，则成反比例．

行走的速度×所需要的时间=王楠从家到学校的路程（一定），则他行走的速度和所需要的时间成反比例；
故答案为：√．

点评：
本题考点： 辨识成正比例的量与成反比例的量．

考点点评： 此题属于辨识成正、反比例的量，就看这两个量是对应的比值一定，还是对应的乘积一定，再做判断．

金满贯是指能 获得了全部能获得的世界金牌 大满贯是指获得了全部能获得的单打世界金牌 邓亚萍和张怡宁没有拿过世乒赛混双冠军 所以不是全满贯 还有一个名词叫金满贯即拿得了世乒赛的全部金牌例如郭跃 金满贯：奥运会单打、团体（或者双打）冠军,世乒赛单打、双打、混双、团体冠军,世界杯单打、团体冠军 大满贯：世界杯,世乒赛,奥运会单打冠军.
