中考网整理了关于2021年初中英语辅导：现在完成时的时间状语，希望对同学们有所帮助，仅供参考。 （1）现在完成时属于现在时范围，故不能和过去的时间状语连用。如：yesterday,last Sunday,in1990,three yearsago等。但是，在强调动作产生的后果和影响时，可以和一些表示不确定的时间状语连用。 a. 用副词already和yet。already一般用于肯定句中，yet一般用于否定句和疑问句中。 如：We have already finished ourhomework.我们已完成作业了。 They haven't finished their homework yet.他们还没有完成作业。 b.用ever 和never。多用于否定或疑问句中，表示“曾经”或“从未“等。 如：-Have you ever been to the Great Wall?你曾经去过长城吗？ -I have never been to the Great Wall.我从未去过长城。 c.用表示到说话为止的过去时间状语，如just, before, up to now, the past few years等。 例如：I haveseen her before, but I can not remember where. 我以前见过她，但记不起在哪里见过。 Hehas been there three times the last few days. 近几年他去过那里三次了。 d.用包括“现在”在内的时间状语，如：now, today, this morning (month ,year,term)等。 例如：-Haveyou met him today?-No,I haven't. 今天你见过他吗？我没有。 Howmany times have you been there this year? 今年你去过那里多少次？ （2）现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始，一直持续到现在。如：I haven't seen him for two years. 但是，像come, arrive, buy等终止性动词不能与表示“一段时间”的状语连用。要用，必须改为“be（在）”等延续性动词来表述 现归纳总结一下由非延续性动词到延续性动词的转换： arrive→behere begin(start)→be on die→bedead come back→be back leave →beaway fall ill(sick,asleep)→be ill(sick,asleep) get up→beup go out→be out finish →beover put on→wear 或be on open →be open join→be in或 be amember of… close→beclosed go to school→be a student borrow →keep buy→have catch(a cold)→ have(a cold) get to know →know begin tostudy→study come to work→work等 如：He has been a soldier for three years.他参军三年了。 His father has been dead for two years.他父亲去世二年了。 The film has been on for ten minutes.电影已开始十分钟了。 We have studied English for three years. 我们（开始）学英语已三年了。 (责任编辑：admin) |
