2019高考英语专题复习完成时态(附答案)
I. 考点分析
1.
完成时态中的考查点通常有现在完成时(have +done)、现在完成进行时(have+been
doing)、过去完成时(had + done)、过去完成进行时(had +been
doing)和将来完成时
(willshall +have
done)等,其中将来完成时和过去完成时出现的频率相当高,几乎达到
每次一题。
A
关于现在完成
1.现在完成时表示对现在仍有影响的某一已发生的动作,常与already,
yet, recently, lately或频
度副词often, never, ever,
seldom, twice等连用,例如:
We have been to the Great
Wall many times.
He hasn’t translated the
novel yet.
2. 表示一个从过去开始延续到现在的动作,常与for +一段时间,
since, in recent years, so far等
词或词组连用;例如:He
has lived in Beijing for 20 years.
The essence
of music has not changed since the beginning of
time.
is (has been)…since这一结构也常用于现在完成时。例如:
It has been (也可用is) a long time since they
last met each other.
4. “This is the first
(second) time that…”句型中,从句常用现在完成时态。例如:
Is
this the first time that you have visited Hong
Kong?
This is the second time that I have
broken a cup this week?
5.可用于if, unless, when,
as, until等引导的条件和时间状语从句中,表示将来完成的动作。例
如:Come here
when you have finished your work.
B关于现在完成进行时
由have (has) + been +现在分词构成,表示动作从过去某一时间开始,一直延续到
现在,可能
还要继续下去,通常与表示一段时间的状语连用,如for hours, since
this morning….例如:
They have been
watching TV for two hours.
He has been working
on this essay since this morning.
现在完成进行时和现在完成
时的第二种(即表示动作延续)的用法相似,并常常可以互换。
它们的区别在于:现在完成进行时比现在
完成时更强调动作的延续性,前者可以说是后者的
强调形式。
C 关于过去完成时
1.由had +过去分词构成,表示在过去某一时刻以前已经完成的动作,常与由by,
before,until
等介词或连词引起的表示到过去某一时间为止的时间状语连用。例如:
The girl had learned a lot of English words
before she went to school.
By the end of last
month, we had finished half of the work.
2.这一时态也常用于宾语或定语从句中。例如:
He found the book
that he had lost.
She thought she had locked
the door.
3.用在表示与过去情况相反的虚拟句的从句中,例如:
If he
had studied hard last term, he would have passed
the examination.
I wish I had gone to the
party last night.
D 关于过去完成进行时
由had been
+现在分词构成,主要表示过去某时以前一直在进行的一个动作,例如:
It had been
raining for two day. The fields were all under
water.
At last they got the telegram they
had been expecting.
E 关于将来完成时
由shall
(will) + have
+过去分词构成,表示将来某个时间之前会发生或可能完成的事情,常与
by, before,
when等介词或连词引导的表示将来的时间短语或从句连用。例如:
When
we get there they’ll probably have left.
By
the end of this century China will have become one
of the strongest and wealthiest country in
the
world.
