Step4LanguageExplanations
1．AlmostallofthemoccurintheUS,intheareafromTexasinthesoutheasttoSouthDakotainthenorth.
occur:
此处意为“发生”，不及物动词，没有被动语态。
如：
About400earthquakesoccurworldwideeveryday,andmorethanaayear.
【辨析】：
occur,takeplace
：
多用于偶发事情。
todosth意为“碰巧恰巧”；tosb意为“…发生在某人身上”。
DoyoutoknowtheNo318themorning.
Thisideasuddenlyoccurredtome.
takeplace：
不带有“偶然”之意，常指经过安排的事情的发生。
TheMay4thMovementtookplacein1919.
2．Thereareviolentwindsof120kmsperandfloods.
cause：
vt.此处意为“导致、引起”，后接名词、代词作宾语，也可接不定式作复合宾语，还可接双宾语。
Whatcaused.“原因，起因”，后可接of短语或不定式。
Thecauseoftheaccidentwascarelessness.
【辨析】：
cause:
强调导致某种结果的原因，即指事物发生的直接原因。
Thewasthecauseoftheflood.
reason:
作名词，意为“理由，原因”，着重指在逻辑推理上引出的结论的原因，其后介词多用for。
如：
Hefordoingthat.
注意：
cause后不接why引导的定语从句，而reason后则可。
如：
Thereasonwhy’tpayattentiontodestroy,please.Don’tleavetherain.
leavesb.todosth.：
意为“交给（委托）某人干某事”，如：
Shewillleavemetolookafterpickupcars,trainsandeveninthenextstreet－oreveninthenexttown.（Page23）
**pickup：
在此意为“卷起、掀起”。
Thewindfromnorthwestpickedupdustandleavesontheground.
【拓展】：

Step2Explanation
1.被动语态ThePassiveVoice
构成：
be+及物动词的过去分词
主动语态：
Workersmakecars.被动语态：
Carsaremadebyworkers.
结论：
谓语动词的执行者作主语，谓语动词为主动语态；承受者作主语，谓语动词为被动语态。
主要用法：
（1）当我们不知道动词的执行者是谁，或者动作的执行者是谁并不重要时，需要用被动语态。
RiceisgrowninNorthChina.SilkisproducedinHangzhou.
（2）当我们需要强调动词的承受者时，常用被动语态。
Thisknifeisusedforcuttingpaper.Thekeyisusedforlookingandopeningthedoor.
注意：
A.不及物动词通常不能构成被动语态。
B.情态动词的被动语态由“情态动词＋be＋及物动词的过去分词”。
如：
may+be+p.pbe随着人称和时态而变化。
2.过去完成时态的被动语态
过去完成时表示过去某个时间之前已经发完成的动作，即过去完成时的动作发生在“过去的过去”。
使用过去完成时，句子中通常要有明显的参照动作或时间状语，这种时态一般不孤立使用。
其构成形式是hadbeendone被动形式是hadbeendone。
Theysaidthattheirworkfinished.他们说他们的工作已经完成了。
Hesaidthatwhentoleavedecided.他说已经决定了什么时候离开。
BythetimeIarrivedatthebusstation,myfriendpickedup.
我到达车站时，我的朋友已经被人接走了。
Theworkwasdoneearlierthanitplanned.工作比我原先计划的要早
MycomputerallrightuntillastMonday.我的计算机直到上星期一才恢复正常。
