7. What should we do to take care of our Mother Earth?

这是一个口袋问题，欢迎提出任何有创意的idea区解决身边的问题。特别是提出一些从自身做起，从身边做起的建议更能得到考官的认同。

Candidate 1: Our Mother Earth is the only home of man up till the present moment. Everyone has the duty to protect our Mother Earth. As students, what should we do to take care of her?

First, in order to reduce the so-called "white pollution", we could use paper bags instead of plastic bags. We also could take bags that can be used over and over again when go shopping. As we all know, normal plastic bags won't decompose easily. They will pollute the soil in spite of being buried deeply.

Second, we shouldn't throw garbege here and there. And we should make efforts to pick up teh little we see on streets. If everyone can do it, our city and countryside will be cleaner and cleaner.

Third, we have to help people raise their awareness of environmental protection. Our concept is the most important and fundamental. Our concept is the most important and fundamental. Only when we're conscious of its significance, could the environment of our Mother Earth be better and better.

Candidate 2: In the modern society, the economic benefit is considered more and more important. Therefore, the problem of how to take care of our Mother Earth has become very serious. Firtly, we should launch more publicity campaigns to enhance people's awareness of the importance of environmental protection. Secondly, we should do some things from now on, such as collecting the used batteries, recycling the plastic stuff, sorting the rubbish and so on. Last but not least, we should eliminate the pollution at source. For instance, factories should dispose of the waste gas, water or material before discharge. If everyone plays his part, our environment would be improved a great deal. So everybody is supposed to spare no efforts to preserve our Mother Earth—for ourselves, and the future generations of our children, grandchildren, and great-grandchildren.

Candidte 3: Protecting the environment so as to make our Mother Earth in good condition is a daily thing. For example, when summer or winter comes, you may turn on the air conditioner. "In fact, when you heat or cool, your home has a big effect on the earth", says John Cormody, an environmental researcher. He says that bulidings consume more energy than transportation and industry. Almost half of the energy that buildings use goes into heating or cooling.

In my opinion, to protect environment, the government must take even more concrete meansures.

First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the family planning policy into practice, because more people mean more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves. If we do our best, tomorrow will surely be better!

对于口袋问题的回答，需要一定的技巧。仅仅依靠关联词将一些现象铺陈下来，提出相应的建议是不够的，注意内在关联是不可忽视的一个方面。相比Candidate 1而言，Candidate 2在保护地球策略的分析上，内在关联更为明显，从树立意识到脚踏实地，以及反对污染等具体措施，使考官更为容易理解和接受；Candidate 3则突出显示以小见大的表达手法。
