PeriodFiveGrammar—Unrealconditionalsandthingshopedforordesired感知以下句子,完成方框下的小题1.Ifyouhadaskedhimyesterday,youwouldknowwhattodonow.2.Helooksasifhehadseenaghost.3.Helooksasifhewereanartist.4.Ifonlythealarmclockhadrung!5.IfonlyIwereyou!6.Iwishhehadvisiteduslastnight.7.Iwouldrather(that)Ihadnotseenit.8.Iwouldratheryoupaintedthewallgreennexttime.9.Isuggestthatwe(should)holdameetingnextweek.10.Itistimethatthechildrenwent/shouldgotobed.1.句1中从句的谓语动词为hadasked,是与过去事实相反的虚拟语气;主句的谓语动词为wouldknow,是与现在事实相反的虚拟语气。2.由句2、句3、句4和句5可以看出,asif从句和ifonly后的句子常用虚拟语气。表示对过去事实的虚拟用过去完成时,如句2和句4;表示对现在事实的虚拟用一般过去时(be动词常用were),如句3和句5。3.由句6、句7和句8可以看出,wish和wouldrather后的宾语从句中常用虚拟语气。表示对过去事实的虚拟用过去完成时,如句6和句7;wouldrather后接的宾语从句中若表示对将来事实的虚拟则用一般过去时,如句8。4.在表示建议、命令、要求等意义的词如suggest,order,command,require等词后的宾语从句中,谓语动词常用(should+)动词原形,如句9。\n5.由句10可以看出,在句型“Itistimethat...”中,从句的谓语动词可以使用一般过去时或“should+动词原形”,should不能省略。一、错综时间条件句在这种条件句中,虚拟条件句即条件从句和主句所指时间不一致,因此,主句和从句的谓语动词要根据各自所指的不同时间选择适当的动词时态。IfIwereyou,Iwouldn’thavemissedthefilmlastnight.如果我是你,我就不会错过昨晚那场电影。Iftheyhadstartedintheearlymorning,theywouldarriveinhalfanhour.如果他们一大早就出发,再过半小时就该到了。二、含蓄条件句不是用条件句而是由介词或介词短语(without...,butfor...),连词(but),副词(otherwise)或上下文等表示某种假设的情况。Withoutelectricity(=Iftherewerenoelectricity),lifewouldbequitedifferenttoday.如果没有电,现在的生活将会大不相同。Iwasillthatday.Otherwise,Iwouldhavetakenpartinthesportsmeeting.那天我病了。否则,我就参加运动会了。三、虚拟语气在asif/though,ifonly后的从句中的应用1.asif/though引导的表语从句或方式状语从句表示与事实相反的情况时也用虚拟语气。与现在事实相反用一般过去时(be动词用were);与过去事实相反用过去完成时(haddone);与将来事实相反用“would/should/could/might+动词原形”。Theyoungmanwithlonghairwalksasifhewereasmallgirl.留长发的那个小伙子走起路来就像个小姑娘。2.ifonly表示“要是……就好了”,其后虚拟语气的用法见前面PeriodThree“经典句式”中讲的。IfonlyIhadcometothepartyyesterday.如果昨天我来参加晚会就好了。四、虚拟语气在宾语从句中的应用\n1.表示“建议、命令、要求”的动词insist,demand,require,request,propose,suggest,command,order等后面的宾语从句中,谓语动词用“(should+)动词原形”。Heorderedthatthestudents(should)washtheclotheseveryweekbythemselves.他要求学生每周都要自己洗衣服。注意:suggest意为“暗示,表明”;insist意为“坚持说,坚持认为”时,从句中应用陈述语气。Thelookonhisfacesuggestedhewasupset.他脸上的表情表明他很沮丧。Heinsistedthathewasright.他坚持说他是对的。2.在wish后的宾语从句中,用一般过去时表示与现在事实相反的情况;用“could/would+动词原形”表示与将来事实相反的情况;用过去完成时表示与过去事实相反的情况。IwishIwere30yearsyounger.我真希望自己能年轻三十岁。IwishIcouldflytothemoonsomeday.我真希望有一天我能飞到月球上去。3.在wouldrather后的宾语从句中,从句的谓语动词用一般过去时表示与现在或将来事实相反的情况;用过去完成时表示与过去事实相反的情况。I’dratherwehadarestnow.我希望我们现在休息一下。五、虚拟语气在主语从句中的应用1.“It+is+形容词+that引导的主语从句”句型中的虚拟语气,从句谓语动词用动词原形或“should+动词原形”。用于本句型中的形容词有:necessary,important,surprising,strange,shocking,natural,essential,reserved,urgent,impossible等;还有与表示提议、要求、命令等动词有关的形容词,如desirable(←desire),urgent(←urge),advisable(←advise),preferable(←prefer)等。Itisnecessarythathe(should)listentotheradiofrequently.他很有必要常听收音机。Itisimpossiblethatthey(should)feeluncomfortabletolivewithus.他们跟我们住在一起不舒服,这不可能。\n2.“It+is+过去分词+that引导的主语从句”句型中的虚拟语气,从句谓语动词用动词原形或“should+动词原形”。用于本句型中的过去分词就是表示提议、要求、命令等动词的过去分词,如suggested,required,requested,demanded,urged,proposed,ordered,desired,advised等。Ithasbeensuggestedthatthemeeting(should)beputoff.有人建议推迟会议。Itisrequiredthatyou(should)wearpropersuitstotakepartintheparty.参加这个晚会要求着装恰当。六、虚拟语气在表语从句和同位语从句中的应用虚拟语气用在表示说话人的愿望(desire),建议(suggestion,advice),要求(requirement,demand),命令(order,command)等名词后面的表语从句和同位语从句中,从句谓语动词用“(should+)动词原形”。Oursuggestionisthatyou(should)bethereontime.我们的建议是你应该按时到那儿。Whatdoyouthinkofhissuggestionthatwe(should)putonaplay?他建议我们演一出剧,你觉得怎样?1.It’sstrangethathehavetakenthebookswithouttheowner’spermission.(2018·江苏,24)A.wouldB.shouldC.couldD.might答案
