Sample 1： Statistics of Family Expenses in Shanghai

　　As is shown in the table above, dramatic changes have taken place in family expenses in the City of Shanghai within two decades (from 1980 to 2000). The most obvious change is in expense on food and clothing, which has dropped by 48%, while those on recreation, education and health care have increased respectively by 5%, l6% and l0%. Expenses on other things keep rising from 17% to 35%.

　　The statistics of rise and fall seem to exist in isolation but are in fact closely related to one another. The most likely factors accounting for these changes are as follows:

　　Development in economy is the fundamental one. The increased income results in the lowering percentage of food and clothing.

　　Another factor lies in the development of people’s concept. People begin to interest themselves in recreation and education.

　　These changes should also be attributed to social reforms. In the 1990’s, college education was not totally free as it was before, which also accounts for the rising expenses on education. Soon after, the government gradually stopped offering houses to its citizens without charges. People had to save a large proportion of their money for housing. That's partly why the expenses for ''others'' doubled. As for the more expenses on health care, I figure there are two main reasons: the cancellation of free medical care and people’s awareness of the importance of health.

　　The changes reflect the development of the city and indicate that people are enjoying more.

　　Sample 2：

　　根據(jù)國務院發(fā)布的：限塑令”，自2008年6月1日起，在所有超市、商場實行塑料購物袋有償使用制度，超市、商場一律不得免費提供塑料購物袋。請你寫一篇英語短文，要求包括以下內(nèi)容：

　　As we all know, white trash mainly refers to the plastic bags we consume everyday. And this pollution has been affecting us for many years. It is reported that 3 billion plastic bags are used on a daily basis. Fortunately, the government has take measures to deal with the increasingly serious problem. A new ban was launched not quite long ago that plastic shopping bags are no longer free.

　　This ban is significant in the following aspects. First of all, it contributes to the reduced quantities of plastic bags and therefore can relieve the pressure of white trash on the environment.

　　Furthermore, the environmental awareness will be strengthened and thus benefit other aspects of the environmental protection.

　　In all, we have only one earth, which doesn’t belong to our generation only. It’s the responsibility for every individual to take actions to protect it. Let’s use more cloth bags, baskets instead of plastic bags. Only by taking actions can we really rescue our mother earth from being drown in the trash.
