Unit7

◆溫故◆在英語中，動詞有兩種語態，即主動語態和被動語態。主動語態表示主語是動作的執行者，被動語態表示主語是動作的承受者。在前面兩個單元我們已經學習了一般現在時的被動語態和一般過去時的被動語態，它們的結構為：are/is+及物動詞的過去分詞,were/was+及物動詞的過去分詞。含有情態動詞的被動語態◆知新◆本單元我們主要了解含有情態動詞的被動語態。它的結構是什么呢？觀察下面例句中含情態動詞被動語態的各種形式，然后補全結論中所缺的內容?！纠洹?.Manytreesshouldbeplantedinthemountains.應該在山上種許多樹。2.Youcantakethisbookhome.（改為被動語態）→Thisbookcanbetakenhome(byyou).3.Thisproblemcan’tbeworkedoutveryeasily.這道題輕易算不出來。4.Musttheworkbedoneatonce?這項工作必須立即完成嗎？【結論】A.含有情態動詞的被動語態的結構為：情態動詞+___+及物動詞的________。B.含有情態動詞的主動語態變為被動語態時，要把主動語態的_____變成被動語態的主語。C.變為否定句時只需要在情態動詞后加_____。D.變為一般疑問句時只需把________提到句首。be過去分詞賓語not情態動詞【運用】Ⅰ.選擇最佳答案。(

asmuchashewants?Whyorwhynot?Theybelievethatheshouldstudyhardintheevening.6.OnlythenwillIhaveachancetoachievemydream.

這是一個倒裝句，正常語序是Iwillhaveachancetoachievemydreamonlythen.但由于與前文的連貫性及強調的需要，onlythen被置于句首。英文的句子大多主語在前，謂語在后。但在一些句子中，由于修辭或句子結構上的需要，謂語被部分或完全置于主語之前，構成“倒裝語序”。only用于句子的開頭，后接副詞、介詞短語或狀語從句時，句子應倒裝。例如：Onlyyesterdaydidhefindoutthathiswatchwaslost.直到昨天他才發現他的手表丟了。OnlyafterayeardidIbegintoseetheresultsofmywork.直到一年后，我才開始看到我工作的成果。Writeadiaryentryexplainingwhichrule(s)youdonotagreewithathomeandhow
