2020届高考英语二轮复习教师用书：2020届老高考英语二轮对点集训：第一板块专题三第五讲情态动词和虚拟语气

[小题夯基练]Ⅰ.单句语法填空1．They ____________ (arrive) at suppertime but their flight was delayed.解析：should have arrived　[should have done sth.意为“(过去)本应该做某事而未做”，分析句意可得出答案。]2．Maybe if I ____________ (study) science，and not literature then，I would be able to give you more help.解析：had studied　[根据then一词可确定此处表示与过去事实相反，故if引导的从句部分用had done形式。]3．Teachers recommend parents ____________ (not allow) their children to watch too much TV.解析：(should) not allow　[recommend，suggest，advise，order，request，insist等表示“建议、命令、要求”等意思的动词，后接宾语从句时，宾语从句的谓语动词常用“should＋动词原形”，should可省略，此处表示老师建议家长不允许孩子看太多电视。]4．He always acts as if he ____________(know) everything.解析：knew　[在as if引导的方式状语从句中，用一般过去时表示与现在事实相反。]5．If we had taken such effective measures much earlier，the river ____________ (not pollute) so seriously now.解析：would not be polluted　[从句表示与过去事实相反，由now可知，主句表示与现在事实相反，故主句谓语动词用“would＋动词原形”，且river与pollute构成被动关系。]6．—What will you do during the summer holiday?—I don't know，but it's  high time that I ____________ (decide) something.解析：decided/should decide　[在It's (high) time that...中，that从句应用虚拟语气，从句谓语用should do或过去式。]7．—Where have you been?—I ____________ (stick) in the heavy traffic.Otherwise I ____________ (come) here earlier.解析：was/got stuck；would have come　[第一空表示过去的一个客观事实，用一般过去时；第二空表示与过去相反的虚拟语气主句用would have done结构。]8．—Would you mind if I set out earlier tomorrow morning?—Well，I would rather you ____________ (not do)．解析：didn't　[would rather后的宾语从句需用虚拟语气，表示与现在或将来事实相反，谓语动词用一般过去式。]9．I ____________ (not decide) to give a try，but for the teacher who kept insisting on my “going for it”．解析：wouldn't have decided　[but for后的真实句表示过去的情况，故空格处的虚拟主句用would have done结构。]10．Had I known about this computer program，a huge amount of time and energy ____________ (save) then.解析：would/could/might have been saved　[if虚拟条件句的倒装结构和主句均是对过去情况的虚拟，且主语time and energy 和动词save构成被动关系。]Ⅱ.单句改错(每句一错)1．You can be Tom.You haven't changed a bit after all these years.____________解析：can→must　[根据后文的You haven't changed a bit...可知说话者完全认出了Tom，猜测的语气很肯定，因此用must。]2．Do I need leave my telephone number and address？____________解析：need后加to　[判断need在一般疑问句中作情态动词还是实义动词要看是否把need提前，若提前，则need为情态动词，若不提前，则为实义动词。本题为实义动词，则need要后接to do不定式。]3．Have I been informed earlier，I could have done something.____________解析：第一个Have→Had　[表示与过去事实相反的虚拟条件句中有had时要把had提至主语前，变为倒装句式，没有把have提前这种用法。]4．Just as I am busy，shall you come bothering me with some questions now？____________解析：shall→must　[must意为“偏偏……”，常指令人不快的事情，表示说话人的生气或困扰。shall无此用法。]5．Would you be fired，your health care and other benefits would not be immediately cut off.____________解析：第一个Would→Should　[虚拟条件句中表示与将来事实相反时，条件从句用should do，were to do或过去式形式。没有would do用法。]6．When you phoned me，I was having a meeting；how I wish I answered your call.____________解析：answered前加had　[句意：当你给我打电话的时候，我正在开会。我多么希望我(之前)接了你的电话。wish后的从句中用虚拟语气，根据句意可知是对过去情况的虚拟，所以谓语动词用had done形式。]7．I was ill that day，or I will have taken part in the sports meet.____________解析：will改为would/should/could/might　[由句中or可知此处为含蓄条件句，表示与过去事实相反的假设。]8．(2020·南昌十校一模)As a result，I suggest we are given less homework and more time for out­of­classroom activities.____________解析：are→be　[suggest 在此处表示“建议”，因此后跟的宾语从句应用虚拟语气，即从句谓语用“should＋do”形式，且should可以省略，故此处应把are改为be。]9．(2019·郑州第二次预测)He became very angry，but I dared not to tell him about the game.____________解析：删除to　[dare既可以作情态动词又可以作实义动词。dare的过去式为dared，此处其前没有用助动词，说明dare在此用作情态动词，故后跟动词原形。]10．People neglect the fact that our parents are the dearest persons in the world，so we should nice to our parents.____________解析：should后加be　[情态动词后用动词原形，而nice为形容词，因此其前缺少be动词，故在should后加be。][大题提能练]Ⅰ.语法填空——情态动词和虚拟语气专练　Lucy is an outgoing lady.She ____1____ play many kinds of musical
