    I took the Harvard Summer School program in my vacation. During my stay there, I spend a lot of time studying in the main library Widener. I enjoyed myself in the ocean of knowledges, either doing research for my papers or read special edition books. The library, which it is named after its donor Harry Widener, stands right next to the Emerson building of philosophy. Opening a pair of heavy yet elegant metal doors, I was immediate bathed in warm light. I wandered around the library, fascinating to find one treasure after other.

    The library is a amazing place. One can fully experience the academic atmosphere only he visits the library. For me, the library as well as the courses explain Harvard's place as the home of devoted scholars.

    Square dancing has been more and more popular with the elderly as their living conditions improve. Most people thought it can help people take regularly exercise and improve their fitness. Besides, it provides people more chances to take activities outdoor. However, some people argue that the music is very noisy, that disturbs the surrounding citizens' normal life. Also, be exposed to such loud noise may do a harm to their health in the long run.

    In my opinion, square dancing is a good form of exercise, so dancers should take our neighbors' needs into consideration. If they choose a right time and turn down the music, it will cause less troubles for others.

Dear Mary,

    I received your E-mail just now. Don't worry about me. I'm getting well with my research work in the lab. But to my great surprised, you say you will give up learning English. The reason is because you have not done well in it recently and you have lost interests in it. I'm afraid I can't agree with you more. I know it is difficult to learn English, but English is wide used in the world today. It will be a important tool in our future work. Besides, it is becoming more and more important in ours daily life. If you study hard, you would be successful. Do remember that where there is a will, there is a way. I'm looking forward to hear good news from you.

Yours,

Li Hua
