高考英语语法词汇专项突破：02重点语法易错易混点（时态、非谓语动词和系动词）

高考英语语法词汇专项突破：02重点语法易错易混点（时态、非谓语动词和系动词） 本文重点辨析相关时态（一般现在时、现在进行时、现在完成时、一般将来时、一般过去时、过去完成时、过去进行时）、的用法，现将它们的易错易混点总结如下： 【误用1】 If you don’t go for a picnic this Sunday, neither do I. 【指正】 do改为will / shall。 在复合句中，主句用一般将来时，条件状语从句（if, unless, once等）、时间状语从句（when, before, after, as soon as, until等）和让步状语从句（although, whatever, however等）中用一般现在时代替一般将来时，简称为“主将从现”。 【运用】 If you are free this Sunday, we will go to the science museum. I will telephone you as soon as I reach Beijing. Although the work is very difficult, we will never give up. 【误用2】 The timetable says the train for Wuhan is leaving at 9:30 a.m. 【指正】 is leaving改为leaves。 根据时刻表规定或安排将要发生的事要用一般现在时代替一般将来时。leave, come, go, stay等词的一般现在时表示将来。 【运用】 The next train leaves at 3 o’clock this afternoon. Where do we go now? 【误用3】 —Haven’t seen you for ages! Where have you been? —I have stayed in Xinjiang for one year, working as a volunteer. 【指正】 have stayed改为stayed。 一般过去时也可以和“for + 一段时间”连用，表示过去某个动作或状态持续了一段时间。同学们切不可思维定势，认为“for + 一段时间”只能和完成时连用。 【运用】 Mr. Wang taught English in our school for 20 years; now he is retired. I once studied in the No. 2 Middle School for three years. 【误用4】 —Tom, give me your report by 3:00 p.m. —Since when are you in charge of this project? 【指正】 are you改为have you been。 since后跟表示时间的词、短语或从句时（从句用一般过去时），主句要用现在完成时，强调对目前的影响。主语是it时，主句用一般现在时或现在完成时均可。 【运用】 He has taught here since 2000. I have lived in the house since I came here. It is / has been two months since I met her. 【误用5】 —Have you closed all the windows? It’s going to rain. —Sorry, I forgot, but I’m going to close them in a minute. 【指正】 I’m going to改为I will。 be going to do sth.强调事先打算做某事，而will do sth.可以表示临时决定做某事。此处是“我”原先忘记关窗了，现在经对方提醒才想起来，所以临时决定过会儿去关窗。 【运用】 He is going to play basketball after school this afternoon. I’ll go shopping in 10 minutes. 【误用6】 —You were out when I visited you this morning. —Oh, I had waited for a friend from Australia at the airport. 【指正】 had waited改为was waiting。 根据语境，此处指“当你来时，我当时正在机场等朋友”，故要用过去进行时。过去完成时指在过去某个特定时间之前已经发生的动作。 【运用】 When I
