【英语】2020届二轮复习核心语法考点练情态动词和虚拟语气学案

语法专项（二）情态动词和虚拟语气 单句语法填空 ‎1．(2019·重庆第一次质量抽测)If the new safety system (bring) into use, the accident would never have happened.‎ had been brought　解析：句意：如果新的安全系统已经投入使用，事故就不会发生了。根据句意、句子结构以及主句中的would never have happened可知，句中If引导的是虚拟条件句，且表示与过去的事实相反的假设，故从句时态应用过去完成时。‎ ‎2．(2019·浙江杭州地区七校模拟)When you phoned me, I was having a meeting; how I wish I (answer) your call.‎ had answered　解析：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。‎ ‎3．(2019·安徽江淮十校联考)As the deadline is drawing near, no one leave with his own work uncompleted.‎ shall　解析：句意：因为截止日期即将到来，不完成工作，任何人不许离开。shall用于第三人称陈述句中，表示命令、警告，符合句意。‎ ‎4．(2019·东北三校联考)The order came that the medical supplies (send) to the earthquakestricken area soon.‎ ‎(should) be sent　解析：表示建议、要求、命令等名词，如：suggestion, order, request, advice等后接的表语从句、同位语从句中谓语动词用(should＋)动词原形。‎ ‎5．(2019·湖北四地七校联考)It is high time that you (consider) that if there were no stress in your life, you would achieve a little.‎ considered/should consider　解析：在It is high time that...句式中，从句用虚拟语气，即：谓语动词用过去式或should＋动词原形。‎ ‎6．(2019·天津七校4月联考)I was ill that day, otherwise I (take) part in the sports meet.‎ would have taken　解析：句意：那天我病了，否则我就参加运动会了。根据语境可推知，设空处为与过去事实相反的虚拟语气，故答案为would have taken。‎ ‎7．(2019·湖南长沙四校模拟)—I (not) thank you enough for what you have done for me.‎ ‎—You’re welcome.‎ can’t　解析：句意：——你为我做的一切我无论怎么感谢都不为过。——不用谢。can not...enough表示“再……也不为过”。‎ ‎8．(2019·广东惠州二调)Harry is feeling uncomfortable. He have drunk too much at the party last night.‎ must　解析：句意：Harry觉得不舒服，他昨晚在聚会上肯定喝太多了。由last night及语境可知，此处表示对过去的肯定情况把握较大的推测。must have done sth.“一定做了某事”。‎ ‎9．(2019·江苏苏州调研)John wants to see me now, but I have so much work on hand that I would rather he (come) tomorrow than today.‎ came　解析：句意：约翰现在想看我，但是我手头有很多工作要做，我宁愿他明天来而不是今天。would rather后面接从句，用虚拟语气，和现在或将来相反用一般过去式，和过去相反用过去完成时，故填came。‎ ‎10．(2019·包头模拟)As Father and Mother thought it was a big occasion for me, they suggested I (hold) a birthday party at home to celebrate it.‎ ‎(should) hold　解析：suggest表示“建议”时后面宾语从句的谓语动词应用(should＋)动词原形，故填(should) hold。‎ 单句改错 ‎1．(2019·石家庄一模)Whenever I made mistakes and felt discouraged, my teacher and my classmates would help me figure out how I must have avoided them.‎ ‎ ‎ must→could　解析：根据语境可知，该句表示“过去本能够做但却未做”，故用could have done。‎ ‎2．(2019·山东曲阜模拟)We needn’t to do so much homework. Therefore, we have more time for afterschool activities.‎ ‎ ‎ 去掉to　解析：need可作实义动词，有时态和数的变化；也可作情态动词，后接动词原形。根据needn’t可知，need在此为情态动词，后接动词原形。‎ ‎3．(2019·成都模拟)In my opinion, by doing parttime jobs, college students must gain some social experience and broaden their outlooks.‎ ‎ ‎ must→can　解析：根据语境可知，此处表示通过做业余工作能够获得社会经验，而不是一定获得。‎ ‎4．(2019·安徽合肥期中)When I got the papers, I realized that things would be better if I listened to the teacher attentively.‎ ‎ ‎ 在listened前加had　解析：根据语境和主句中的谓语realized可知，if 引导的条件状语从句所叙述的事情与过去的事实相反，应用虚拟语气，故if条件状语从句的谓语动词应用过去完成时。‎ ‎5．(2019·河北邯郸联考)When you walk into the gallery, you feel as if you are inside a fragile, white seashell.‎ ‎ ‎ are→were　解析：as if后接表语从句，根据句意“你感觉自己像是身处于一枚易碎的白色贝壳之内”可知，此处是对现在事实的虚拟，从句应用一般过去时。‎
