2、ers recommend parents _ (not allow) their children to watch too much TV.解析:(should) not allowrecommend,suggest,advise,order,request,insist等表示“建議、命令、要求”等意思的動詞,后接賓語從句時,賓語從句的謂語動詞常用“should動詞原形”,should可省略,此處表示老師建議家長不允許孩子看太多電視。4He always acts as if he _(know) everything.解析:knew在as if引導(dǎo)的方式狀語從句中,用一般過去時表示與現(xiàn)在
3、事實相反。5If we had taken such effective measures much earlier,the river _ (not pollute) so seriously now.解析:would not be polluted從句表示與過去事實相反,由now可知,主句表示與現(xiàn)在事實相反,故主句謂語動詞用“would動詞原形”,且river與pollute構(gòu)成被動關(guān)系。6What will you do during the summer holiday?I dont know,but its high time that I _ (decide) something.
4、解析:decided/should decide在Its (high) time that.中,that從句應(yīng)用虛擬語氣,從句謂語用should do或過去式。7Where have you been?I _ (stick) in the heavy traffic.Otherwise I _ (come) here earlier.解析:was/got stuck;would have come第一空表示過去的一個客觀事實,用一般過去時;第二空表示與過去相反的虛擬語氣主句用would have done結(jié)構(gòu)。8Would you mind if I set out earlier tomor

6、rogram,a huge amount of time and energy _ (save) then.解析:would/could/might have been savedif虛擬條件句的倒裝結(jié)構(gòu)和主句均是對過去情況的虛擬,且主語time and energy 和動詞save構(gòu)成被動關(guān)系。.單句改錯(每句一錯)1You can be Tom.You havent changed a bit after all these years._解析:canmust根據(jù)后文的You havent changed a bit.可知說話者完全認出了Tom,猜測的語氣很肯定,因此用must。2Do I

9、meeting;how I wish I answered your call._解析:answered前加had句意:當(dāng)你給我打電話的時候,我正在開會。我多么希望我(之前)接了你的電話。wish后的從句中用虛擬語氣,根據(jù)句意可知是對過去情況的虛擬,所以謂語動詞用had done形式。7I was ill that day,or I will have taken part in the sports meet._解析:will改為would/should/could/might由句中or可知此處為含蓄條件句,表示與過去事實相反的假設(shè)。8(2020南昌十校一模)As a result,I su
10、ggest we are given less homework and more time for outofclassroom activities._解析:arebesuggest 在此處表示“建議”,因此后跟的賓語從句應(yīng)用虛擬語氣,即從句謂語用“shoulddo”形式,且should可以省略,故此處應(yīng)把are改為be。9(2019鄭州第二次預(yù)測)He became very angry,but I dared not to tell him about the game._解析:刪除todare既可以作情態(tài)動詞又可以作實義動詞。dare的過去式為dared,此處其前沒有用助動詞,說明d
