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。
