原来物体振动产生声音，每种声音都有它自己的频率，当一种物体发声时，与它相同频率的另一种物体也有可能发声，这就是共鸣。在我们周围有无数声音存在，其中肯定有与水杯里的空气频率相同的声音，这时，水杯中的空气与外界的`相同频率的声音产生了共鸣，所以，我们就听到了嗡嗡声。而用陶瓷杯听到的声音比纸杯和玻璃杯都要小，这是因为陶瓷杯的材料比较厚，而用小茶杯几乎听不到声音，和小茶杯太矮，空气较少有关。
通过这次的实验，我明白了，原来就是这样一件既普通又平凡的事，里面也会隐藏着很多奥秘啊。

I have been back, and write this letter to show my thanks. As the exchange student, you make me feel warm. Welcome to my country ,I’ll show you around in turn.
However , there exists a problem that I have left my dictionary at your home. I like it very much , for it was a precious gift from my teacher who comes from the U.S. I guess that my book may stay on your shelf in the bedroom .
Do you mind if you send my dictionary to me? I will pay for the postage and I’ll be very grateful if you show your warmness again.
I’m eager to receive your reply.
Yours,
Li hua

Dear Mike,
You asked me about the present situation of the public transportation in Wuhan in the last letter.
Now, I will communicate the action of the government and my opinion with you.
Firstly, the price of the bus has been cut down, which is very important, I think. Encouraging people to take bus can solve the biggest problem--too much people.
Another way is to develop the bike rental. As we know, car is much bigger than the bike obviously. Driving a car takes up much more place than cycling. So, developing the bike rental is an absolutely correct way to prove traffic circumstances.
Besides, government also builds 4 subway lines under the central of the city and increases the number of the taxis.
In my opinion, all the action above is useful. When the actions above are all finished, the city will be more perfect.
Yours,
Li hua

亲爱的李华：
很高兴收到你的来信。一切都好吗？你上一封信中说你才刚跟你父母从夏威夷度假回来。我真的很开心你能有这个开心的一段旅途。从你跟我对夏威夷的'描述来看，那真的是一个很美的地方。我希望有一天我也能到那里旅游。我最近有点点压力，因为我准备要考期末了。我对英语，语文还有数学很有信心，但是很担心化学。你知道的，我化学一直都不好。我很怕因为化学把这次期考给弄砸了。噢，别想我的烦恼了。圣诞节就要到了，你现在肯定是在忙着准备吧。提前祝你圣诞节快乐。
李
