An earthquake is a terrible experience!However,there is no advance warning nor is there a particular time of year,like monsoons(季風(fēng)),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.

【課文原句】The 7.8-magnitude earthquake damaged many buildings,and early reports said that about 230 people were killed and more than 1,500 were injured.
這場7.8級的地震破壞了許多建筑,早期報道稱大約230人死亡,1 500多人受傷。
【詞匯精講】句中的damage意為“損壞”,是及物動詞。
Their houses were damaged by the fire.
他們的房子在大火中受損。

如果我們預(yù)先得到警告的話我們就可以減少損害。

2.survivor n.幸存者;生還者
【課文原句】Volunteers and rescue workers are helping the survivors.志愿者和救援人員在幫助幸存者。
【詞匯精講】句中的survivor意為“幸存者”,是可數(shù)名詞。
Officials said there were no survivors of the plane crash.
官方說這次飛機(jī)失事無一人生還。

3.flood n.洪水;大量

【詞匯精講】句中的flood意為“洪水”,若指“一次洪水”是可數(shù)名詞,表示泛指意義的“洪水”是不可數(shù)名詞。

重點句式
Rescue workers and soldiers are working day and night to make sure that people are safe.
救援人員和戰(zhàn)士日日夜夜努力工作確保人們的安全。
【句式剖析】本句總體上是一個復(fù)合句。Rescue workers and soldiers是句子的主語,are working day and night是謂語和狀語,to make sure...是動詞不定式短語做目的狀語,在狀語中有一個that引導(dǎo)的賓語從句。
【句式拓展】
(1)不定式和不定式短語做目的狀語,主要用來修飾動詞,表示某一動作或狀態(tài)的目的。為了使目的意義更加清楚或表示強(qiáng)調(diào)意義時,還可以在前面加 in order to 或 so as to。
My brother went to the shop to buy some fruit.
我哥哥到商店去買些水果。
I’ve written it down in order not to forget.
我記了下來,以免忘了。
He shouted and waved so as to be noticed.

(2)當(dāng)不定式或不定式短語有自己的執(zhí)行者時,要用不定式的復(fù)合結(jié)構(gòu)“for sb to do sth”。
He opened the door for the children to come in.
他打開門讓孩子們進(jìn)來。
