To see a world in a grain of sand,

And a heaven in a wild flower,

Hold infinity in the palm of your hand,

And eternity in an hour.

一沙一世界，

一花一天堂，

手中即无限，

永恒亦短暂。

New Technology Is One Way to Solve Noise Pollution

There have been an increasing number of complaints and lawsuits about noise pollution in some major world cities. The problem with noise is not only that it is unwanted, but also that it negatively affects human health and well-being. In my opinion, the government should attach importance to the research and application of technology in order to reduce noise pollution.

First, the application of sound-absorbing or sound-insulation material shows the quickest sign of the reduction of noise pollution. Noise inside a building can be reduced if both the external and internal walls are made of sound deadening materials. Heavy and dense materials such as masonry or brick walls are better for sound reduction. The application of sound reduction materials is economically and technically feasible in dealing with four main noise sources, namely transportation, industrial production, construction, and social activities. Furthermore, the introduction of hybrid cars has made advances in the reduction of motor vehicle noise. Noise from transportation is one major source of noise pollution. The application of cars with low level noise will be effective in reducing noise emission.

In conclusion, with people exposed to dangerous sound levels on the rise, noise pollution has become a common occupational and environmental hazard. I strongly recommend that the government should spare no efforts in funding and investing in new technologies which will be essential in noise pollution reduction. (227 words)

Dear Sir or Madam:

I'm 名字, a second-year student from Business Department. I'm writing to make a proposal about holding a college-wide English public speaking contest with the topic of _University as I see it_.

The aims of the contest are twofold. First, students all over the University are offered an opportunity to demonstrate their ability to communicate effectively in English. Second, the contest could serve as a forum for students from different background to share their insights and experiences. It is important to note that only a current undergraduate student is eligible for the contest. Each of the contestants would be asked to deliver a prepared speech of 5 minutes and an impromptu speech based on the topic assigned after the prepared speech. The contest would be an off-line event at the International Conference Hall on 日期. A panel from the ESL faculty shall select five finalists from all participants. The finalists would present their speeches after which three winners (and two honorable mentions) would be chosen.

I'm looking forward to your reply. Thank you very much for everything you've done. Wish you all the best.

Yours sincerely,

Name

参考范文：

Last Sunday, a profound activity, school project of collecting used books, was held on campus. A host of students poured their passion into the event and almost everyone considered it as a meaningful way to access to knowledge, based on the actual situation yesterday.

Our university student union had made some arrangements for the project. From my perspective, the following two purposes can interpret this activity. To begin with, this kind of activity would cut down expenses of students, cultivating the awareness of saving. In the mean time, collecting used books can decrease the recycling and reprinting of books, and it is also benefit for the protection of environment. Anyone in the school who was curious about the project registered their names on the list and brought their books to student union’s office, Room 115, E Building last Friday.

The collected books have been displayed in the library. All students who attended the event enjoyed this marvellous period.
