2 、不规则动词:见不规则动词表
分词用法:
1、分词作状语
分词在句子中作状语,可以表示时间、条件、原因、结果、让步、伴随等。
分词(短语)作状语时,其逻辑主语应与句中主语相一致。
当现在分词表示的动作发 生在谓语动词之前时, 则用现在分词的完成式,且所表示动作与谓语动作同时发生, 则用现在分词的一般式。
完成或被动关系用过去分词。
①现在分词:
The students went out of the classroom, laughing and talking.
②过去分词:
Accompanied by his friend, he went to the railway station.
Given better attention, the plants could grow better.
2、“while ( when, once, until, if , though等连词)+分词”结构
现在分词或过去分词作状语时,有时可以在分词前加while,when, once, although, until, if等连词。
①现在分词:
When leaving the airport, she waved again and again to us.
While waiting for the train, I had a long talk with my sister about her work……
②过去分词:
Once recovered, he threw himself into his work and made every effort to do it well.
Although working very hard, he failed to pass the final exam. If translated word by word, the passage will be difficult to understand.
3、分词作定语
分词作定语时,单个的分词通常放在被修饰的名词之前,分词短语一般置于所修饰的中心词后面。
现在分词修饰的是发出该动作的名词(即与名词有主谓关系),过去分词修饰承受该动作的名词(即与名词是动宾关系)。
We will go on with our experiment as soon as we get the added fund.
This is really an exhausting day to all of us!
We can see the part of the moon lighted by sunlight.
After a night spent in excitement and sleeplessness, I forced myself to take a long walk along the beach the next day.
More and more developing countries established strategic partnership with developed countries
4、分词作宾语补足语
现在分词在see, watch, hear, observe, notice, feel, find, glimpse, glance等感官动词和look at, listen to等短语动词以及
have, keep, get, catch, leave, set, start, send等使役动词后面与名词或代词构成复合宾语,作宾语补语的成分。
例:I see him passing my house every day.
I caught him stealing things in that shop.
I smelt something burning.
5、分词作表语
分词作表语通常看作形容词来用。
过去分词表示主语的感受或状态,主语多为人。现在分词表示主语的性质,而且主语多为物;
①过去分词:
We were so bored that we couldn’t help yawning.
She felt confused, and even frightened.
②现在分词:
He was very amusing.
That book was rather boring.
很多动词的现在分词都可以作表语:
exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.
基本结构:
主语+had+过去分词vpp.(done)
①肯定句:主语+had+过去分词+其他.
②否定句:主语+had+not+过去分词+其他.
③一般疑问句:Had+主语+过去分词+其他?
肯定回答:Yes,主语+had
否定回答:No,主语+hadn't
④特殊疑问句:特殊疑问词或词组+一般疑问句(Had+主语+过去分词+其他)?
⑤被动语态:主语+had(hadn't)+been+过去分词+其他
过去完成时基本用法:
(1)表示在过去某一时刻或动作以前完成了的动作,即“过去的过去”。
可以用by, before等介词短语或一个时间状语从句来表示,也可以用一个表示过去的动作来表示,还可能通过上下文来表示。
By nine o’clock last night, we had got 200 pictures from the spaceship.到昨晚9点钟,我们已经收到200 张飞船发来的图片。
(2)表示由过去的某一时刻开始,一直延续到过去另一时间的动作或状态,常和for, since构成的时间状语连用。
He said he had worked in that factory since 1949.他说自从1949年以来他就在那家工厂工作。
(3)叙述过去发生的事情,在已叙述了过去发生的事情后,反过来追述或补述以前发生的动作时,常使用过去完成时。
I didn’t know a thing about the verbs, for I had not studied my lesson.我对动词一无所知,因为我没有好好学习功课。
(4)在含有定语从句的主从复合句中,如果叙述的是过去的事,先发生的动作常用过去完成时
She found the key that she had lost.她丢失的钥匙找到了。
(5)过去完成时常常用在宾语从句(或间接引语)中,这时从句中的动作发生在主句表示的过去的动作之前。
I thought I had sent the letter a week before. 我认为我一星期前就把信寄出去了。
(6)在包含有when, until等连词的复合句中,如果主句谓语动词和从句谓语动词所表示的过去动作不是同时发生的,
那么先发生的动作通常用过去完成时表示。
She didn’t go to bed until she had finished he work.她直到把工作做完之后才睡觉。
注意:如果两个动作紧接着发生,则常常不用过去完成时,特别是在包含before和after的复合句中,因为这时从句的动作和主句的动作发生的先后顺序已经非常明确,这时可以用一般过去时代替过去完成时。
(7)动词think, want, hope, mean, plan, intend等用过去完成时来表示过去未曾实现的想法,希望,打算或意图等。
We had hoped to be able to come and see you .我们本来希望能来看看你。
(8)过去完成时还可用在hardly…when…, no sooner…than…, It was the first (second, etc) time (that)…等固定句型中。
It was the third time that he had been out of work that year.这是他那一年第三次失业了。
语法判定:
一、由时间状语来判定
一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有:
(1) by + 过去的时间点。如:
I had finished reading the novel by nine o'clock last night.
(2) by the end of + 过去的时间点。如:
We had learned over two thousand English words by the end of last term.
(3) before + 过去的时间点。如:
They had planted six hundred trees before last Wednesday.
二、由“过去的过去”来判定
过去完成时表示“过去的过去”,是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时。这种用法常出现在:
(1)宾语从句中
当宾语从句的主句为一般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如:
She said that she had seen the film before.
(2)状语从句中
在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时。如:
After he had finished his homework, he went to bed.
注意: before, after 引导的时间状语从句中,由于 before 和 after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都用一般过去时。如:
After he closed the door, he left the classroom.
(3)表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"
We had hoped that you would come, but you didn't.
