Global Shortage of Fresh Water
1. 人们以为淡水是取之不尽的(提示：雨水、河水、井水……)
2. 实际上淡水是非常紧缺的(提示：人口增长、工业用水增加、污染……)
3. 我们应该怎么办
【范文】
At present, many people take it for granted that fresh water will never be used up because we can find it not only from the rain, but also in the rivers, lakes and wells. Consequently, it is not necessary for us to worry about global shortage of fresh water.
In fact, the situation has become so serious that everyone should be aware of it and take immediate actions. With the world population increasing rapidly year after year, water resources are being consumed at an appalling speed. What's more, with the development of science and technology, modern industry needs much more water than before. Thirdly, pollution is also a worrying problem—water in rivers and wells becomes undrinkable because of industrial wastes.
We should take urgent measures to protect fresh water resources. The government should increase the efficiency of water usage by such methods as water recycling and purification of sea water. The people, on the other hand, should form the habit of cherishing every drop of water. Last but not least, pollution must be effectively controlled, if we ever want to improve the quality of life.
【点评】
本篇范文的最大特色是将批驳类与办法类结合，首段指出一些人的错误认识;第二段从三方面进行批驳;第三段指出我们的做法。
范文首先指出，一些人认为淡水是取之不尽的，然后在第二段中进行批驳。首先，水资源正在被以惊人的速度消费。其次，现代工业需要更多的水资源。另外，因为工业污染，有些水已经不适宜饮用了。第三段阐述正确做法，即政府提高水资源的利用率、人人养成节约用水的习惯以及有效地控制水污染。
第一段第一句中的take it for granted表示“想当然”，be used up表示“用完，耗尽”。第三段第一点中的efficiency，recycling和purification分别指“效率”、“再循环”和“净化”。

Why Are There So Many Rural Laborers in Big Cities?
1. 近年来越来越多的民工涌入大城市
2. 产生这一社会现象的原因
【范文】
For a number of years, there has been a steady rise in the number of rural laborers who flood into big cities. Many men work on construction sites, while many women work as dishwashers in restaurants or babysitters for city dwellers. Three reasons, in my mind, can account for this social phenomenon.
First and foremost, the limited land can no longer produce enough crops for an ever-increasing rural population. In the second place, there are far more opportunities in big cities—rural laborers dream of earning money through hard work. Last but by no means least, many of them want to live permanently in big cities, because they admire the way of living there, and wish their children to receive good education.
I firmly believe that if we try our best to create a healthy social atmosphere, rural laborers will make greater contribution to our nation.
【点评】
本题谈论的是一种社会现象。第一段首句引入某一现象，第二句举例说明，第三句是个过渡句，引起下面解释原因段落的第二段;第三段是简洁的结束语，其中的宾语从句嵌套一个状语从句。
范文首先指出大量农民工涌入大城市这一现象，并引出第二段所阐述的三个原因。首先，农村有限的土地不能满足日益增长的人口消费。其次，大城市有更多的工作机会。最后，农民工向往大城市的生活，想永远居住在大城市。末段总结指出，如果创造一个健康的社会环境，农民工就可以为国家做出更大的贡献。
第一段第二句中的construction site表示“建筑工地”，babysitter表示“帮人看孩子的人”。第二段第一点中的rural指“农村的”;第三点中的permanently和admire分别指“永久地”和“羡慕”，receive education指“接受教育”。
预测作文(三)
Silence Is Gold
1. 许多场合中“沉默是金”是正确的
2. 但也有例外的情形
3. 结论
【范文】
When we talk of the famous proverb "Silence is Gold", we should not simply label it as right or wrong, but explore it in depth.
This proverb is especially true under several situations. First, if we have made a promise not to let out a secret, we should always keep silent. Second, we should avoid talking over facts or statistics of which we are not sure. Third, whenever we are expressing our ideas, brevity is the soul of wit and talking too much will always lead to faults and mistakes.
Nevertheless, there are also some exceptions. If we find out a flaw in other's speaking or writing, we should not hesitate a moment to point it out. And to friends or acquaintances seeking advice, we should feel free to help them.
In a word, we can draw the conclusion that in most cases "silence is gold", but in certain circumstances, talking is the right choice.
【点评】
本文的特色在于其并未完全肯定或完全否定所提到的谚语，而是从正、反两个方面去分析，即第二段指出其正确性，第三段谈例外情况;末段总结，呼应全文。
范文首先提出所要讨论的谚语“沉默是金”。第二段分三个方面阐述其正确性，即发誓保守秘密，对于不确定的事情要保持沉默，而在表达自己的思想时，力求简洁。第三段指出例外，为别人指出错误或为朋友等提建议时，不要坚持“沉默是金”。末段总结，呼应第二、三段。
第一段中的label...as...表示“将……看作……”，而explore... in depth表示“深入探究……”。第二段第一点中的make a promise表示“允诺”，let out a secret表示“泄露秘密”，keep silent表示“保持沉默”;第三点中的brevity is the soul of wit也是个谚语，表示“言贵简洁”。第三段第二点中的acquaintance指“熟人”。
