《Natural Disasters》Listening and Speaking PPT

第一部分内容：新课导入

An earthquake is a terrible experience!However,there is no advance warning nor is there a particular time of year,like monsoons(季风),when an earthquake always occurs①.Unlike a tornado or hurricane,there are no known methods② of predicting③ an earthquake.

Though it is estimated④ that about 500,000 earthquakes occur each year,only 100 of them cause damage!However,an earthquake could occur any time of the day or night so it pays to be prepared if you are unfortunately caught in the middle of one.

If you are indoors,stay indoors unless you are in the ground floor where you can easily run outside.The best thing to do if you are indoors is hide under a strong piece of furniture⑤ like a bed or desk.Do not try to head for the stairway if you are living in an upper storey,as the stairways may collapse⑥.

典句欣赏

However,an earthquake could occur any time of the day or night so it pays to be prepared if you are unfortunately caught in the middle of one.

译文:然而,地震可能在一天的任何时候发生,因此,如果你不幸遇到地震,那么做好准备是值得的。

分析:本句总体上是一个由并列连词so连接的并列复合句。an earthquake could occur...是第一个分句,it pays to be prepared...是第二个分句。在第二个分句中有一个if引导的条件状语从句。
