  • 分词
  • 省略句
分词:
就是具有动词及形容词二者特征的词;尤指以-ing或-ed,-d,-t,-en或-n结尾的英语动词性形容词,具有形容词功能,同时又表现各种动词性特点,
如时态,语态、带状语性修饰语的性能及带宾语的性能。
分词分为现在分词和过去分词两种,是一种非谓语动词形式。
现在分词和过去分词主要差别在于:
现在分词表示"主动和进行",过去分词表示"被动和完成"(不及物动词的过去分词不表示被动,只表示完成)。
分词可以有自己的状语、宾语或逻辑主语等。

现在分词构成形式:
①一般在动词原形末尾加ing,如do→doing、sing→singing、comfort→comforting
②以不发音的e、ue结尾的动词,先去e,再加ing,如dance→dancing、hike→hiking、write→writing、make→ making,take→taking
③以ee、oe、ye结尾的动词加ing,如see→seeing、toe→toeing、dye→dyeing
④以重读闭音节结尾的动词,并且末尾只有一个辅音字母,应双写这一字母,再加ing,如cut→cutting、swim→swimming
注:结尾是x则不必双写,如relax→relaxing
⑤以ie结尾的动词,要把ie变成y再加ing,如die→dying,lie→lying.
⑥以ic结尾的动词,要把ic变成ick再加ing,如picnic→picnicking,traffic→trafficking

过去分词构成形式:
1.规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则:
(1)、一般动词,在词尾直接加“ ed ”。(然而要注意的是,过去分词并不是过去式)
work---worked---worked ,  visit---visited---visited
(2)、以不发音的“ e ” 结尾的动词,只在词尾加“ d ”。
live---lived---lived
(3)、以“辅音字母 + y ”结尾的动词,将 "y" 变为 "i" ,再加“ ed ”。
study---studied---studied,cry---cried---cried,try---tried---tried,fry---fried---fried.[1]
(4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”。
stop---stopped---stopped  ,  drop---dropped--dropped
(5)、以ic结尾的动词,要把ic变成ick再加ed,
picnic→picnicked  ,traffic→trafficked
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.


省略句:
是英语的一种习惯用法。按照语法的分析,句子应该具备的成分,有时出于修辞上的需要,在句中并不出现,这种句子叫做省略句。
其特点是:
虽然省去句子语法构造所需要的组成部分,但仍能表达其完整的意义。省略形式多样,从单词、短语到分句,都可以省略,而且各有一定的衔接关系,不容臆断。

省略现象:
一、单词省略
1、省略介词
He spent four hours (in) going over his lessons. 他花了四个小时复习功课。
I ' ve studied Eng1ish (for) five years. 我已学五年英语了。
2、省略连词 that
I believe (that) you will succeed . 我相信你们会成功的。
It ' s a pity (that) he ' s leaving. 他要走,真遗憾。
I ' m sure (that) she will help you. 我肯定她会帮你的。
3、省略关系代词
I ' ll give you all (that) I have. 我要把我所有的一切都给你。
He read the book (which) I got yesterday. 他看过我昨天买的书了。

二、句子成分的省略
1、省略主语
Beg your pardon.
(我)请你原谅。( Beg 前省略了主语 I )
Take care!
当心!( Take 前省略了主语 you )
Looks as if it will rain.
看起来象要下雨。( Looks 前省略了主语 it )
2、省略谓语
Who next?
该谁了?( Who 后面省略了谓语 comes )
The river was deep and the ice thin.
( ice 后面省略了 was )
We ' ll do the best we can.
我们将尽力而为。( can 后面省略了动词 do )
3、省略表语
Are you ready? Yes, I am.
你准备好了吗? 我准备好了。( am 后面省略了 ready )
He was a lover of sports as he had been in his youth.
他还是象年轻时那样,是一位运动爱好者。( had been 后面省略了 a lover of sports )
4、省略宾语
Let ' s do the dishes. I ' ll wash and you ' ll dry.
让我们洗碗吧,我来洗,你来揩干。( wash 和 dry 后面省略了宾语 dishes )
5、省略定语
He spent part of the money, and the rest he saved.
那钱他花了部分,其余的他都存了起来。( the rest 后面省略了定语 of the money )
6、省略状语
He was not hurt. Strange!
他没有受伤,真奇怪!( Strange 前面省略了状语 how )

三、不同句式中的省略
 1. 简单句中的省略:
在对话中,交谈双方都知道谈论的对象,则可以省略句子的主语,省略主语和谓语的现象在交际用语中出现的很多。
(1)Looks like rain.
(2)Hope to hear from you soon.
(3)Sounds like a good idea.
2. 并列句中的省略:
在并列句中,相同的成分如主语,谓语,宾语等都可以省略:
(1)They learn French and we English.
(2)My father planned and built all these houses.
(3)John won the first race and Jimmy the second.
3. 复合句中的省略:
定语从句:
That’s the reason he is late for the conference.
状语从句:
(1)If heated, water will boil.
(2)Tom was attacked by cramp while swimming across the river.
宾语从句:
如果宾语从句中的谓语部分与主句的谓语部分或上文的谓语部分相同,可将从句部分的谓语省略。
We will do what we can(do)to help you.
—Is Mr. King in his office?
 —Sorry, I don’t know(whether he is in his office or not).
4. 动词不定式的省略:在动词不定式结构中,为了避免重复,常常省略不定式结构中的动词原形,只保留to。
—Would you like to go with us ?
 —I’m glad to, but I have to finish my homework.
在used to, ought to, have to, would like/love to, wish to, be going to等结构中,常常省略to后面的动词原形。
(1)They do not visit their parents as much as they ought to.
(2)He doesn’t get up early as he used to.
(3)I’ll hand it in if I have to.
(4)
—Would you like to come tonight ?
—I’d love to.
Tell , warn , order , advise , ask等动词的宾语后面接动词不定式做宾语补足语时,可以省略to后面的动词原形。
(1)He wanted to swim across the river but I warned him not to.
(2)The boy wanted to play football in the street, but his mother told him not to.
