3. What is your insight into earthquakes? How much do you know about other natural disasters?
注意问题的关键词是insight而非reason，因此不能仅仅解析地震成因，也要对地震这种自然灾害的影响、防控等相关方面进行回答。近年来，台风、海啸等频频发生，给人们生活带来了破坏性的损害，如何应对灾害，减少灾害对人类生活带来的损失都是值得关注的话题。

Candidate 1: Whenever I recall the earthquake that befell(降临到) Sichuan Province I would be in a sad mood. Now I often wonder if I can have the slightest idea of the coming earthquake. In my eyes, when the water is boiling in a well, the animals get irritable(暴躁的，易怒的), and clouds indicating earthquakes appear in the sky, I'll predict the earthquake will come.

When we refer to disasters, floods will come to my mind. We experienced the flood in 1998, and floods come each year. Though it's difficult to forecast the flood, I know how to avoid it. Nowadays, people begin to realize the importance of plants, however, trees and grasses were destoryed in the past years. As a result, when it rained, nothing could prevent the soil erosion and floods occurred. So if we want to avoid the flood we should begin with the protection of the plants.

Candidate 2: Earthquake is a natural disaster. When an earthquake occurs, the most obvious features are the shaking of ground, the collapse of houses and the deformation(变形) of roads. About five months ago, China suffered a lot from a severe earthquake which befell on Sichuan Province. And more than eighty thousand people were killed. The earthquake brought us so much sadness. From this earthquake I realize that the nature cannot be conquered, and what we should do is to prepare for that all the time. Other natural disasters I know include mudflow, flood, tornado, hurricane, typhoon, hail, drought, snowstorm, wildfire, tsunami and so on. Floods may wipe out everything. Tornadoes, hurricanes and typhoons, which occur regularly in some areas, are also disastrous. Hallstorms can ruin harvests. Droughts often cause famine. Snowstorms can block streets, roads and even make the communication break down. Wildfires may destroy a large
area of forests, which brings an enormous loss.

Candidate 3: Earthquake is a horrible thing, to be honest. It is just like a tragedy which lasts for a few seconds but ends terribly. Varieties of buildings and shelters are damaged so quichly. The other natural disasters may include tsunami, typhoon, volcanic eruption and so on.

If the earth loses its balance, I'm afraid that it may crash. That is to say, the former whole board may be divided into many pieces. During this period, rivers may change their directions while new hills may appear. Brand-new appearance of the local area may change beyond our imagination. When we unfortunately encounter an earthquake, we should, first of all, try to hide in stable space. Scientists report that earthquakes do little harm to people, but buildings. So find a safe, small and stable space to hide while you are in buildings. God bless you.

三个回答的组织都很清晰，各有侧重。Candidate 1回忆了汶川地震及1998年洪涝灾害，并提出了保护环境的个人建议；陈述上自如运用了排比句；Candidate 2着重描述了地震发生时的影响和特征及其他自然灾害的破坏力；表达上有效地使用了列举法；Candidate 3点出了解自然灾害发生时如何采取有效防护措施的重要性，并列举出一两个自我保护的小常识，回答流畅。
