◆温故◆在英语中，动词有两种语态，即主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。在前面两个单元我们已经学习了一般现在时的被动语态和一般过去时的被动语态，它们的结构为：are/is+及物动词的过去分词,were/was+及物动词的过去分词。含有情态动词的被动语态◆知新◆本单元我们主要了解含有情态动词的被动语态。它的结构是什么呢？观察下面例句中含情态动词被动语态的各种形式，然后补全结论中所缺的内容。【例句】1.Manytreesshouldbeplantedinthemountains.应该在山上种许多树。2.Youcantakethisbookhome.（改为被动语态）→Thisbookcanbetakenhome(byyou).3.Thisproblemcan’tbeworkedoutveryeasily.这道题轻易算不出来。4.Musttheworkbedoneatonce?这项工作必须立即完成吗？【结论】A.含有情态动词的被动语态的结构为：情态动词+___+及物动词的________。B.含有情态动词的主动语态变为被动语态时，要把主动语态的_____变成被动语态的主语。C.变为否定句时只需要在情态动词后加_____。D.变为一般疑问句时只需把________提到句首。be过去分词宾语not情态动词【运用】Ⅰ.选择最佳答案。(

asmuchashewants?Whyorwhynot?Theybelievethatheshouldstudyhardintheevening.6.OnlythenwillIhaveachancetoachievemydream.

这是一个倒装句，正常语序是Iwillhaveachancetoachievemydreamonlythen.但由于与前文的连贯性及强调的需要，onlythen被置于句首。英文的句子大多主语在前，谓语在后。但在一些句子中，由于修辞或句子结构上的需要，谓语被部分或完全置于主语之前，构成“倒装语序”。only用于句子的开头，后接副词、介词短语或状语从句时，句子应倒装。例如：Onlyyesterdaydidhefindoutthathiswatchwaslost.直到昨天他才发现他的手表丢了。OnlyafterayeardidIbegintoseetheresultsofmywork.直到一年后，我才开始看到我工作的成果。Writeadiaryentryexplainingwhichrule(s)youdonotagreewithathomeandhow
