什么是主语补足语?请例举详细的例子
主语补足语即被动语态中的宾语补足语.
eg.They caught boy stealing.
被动语态 The boy was caught stealing.
stealing 即为主语补足语
被动语态后的主语补足语
对于主语补足语,语法家们各有不同的看法.有的把连系动词后面的部分称作主语补足语;有的又把被动语态后的补足语称作表语,与被动语态一起称作复合谓语.笔者通过教学体会到,还是把被动语态后面的补足语称作主语补足语好些.这是因为学生很容易接受“宾语补足语”,而如果把带有宾语补足语的句子变成被动句,原来补充说明宾语的部分就变成补充说明主语了.
一、被动语态的主语补足语与主动语态的宾语补足语是密切相关的.例如:
(1) I saw him playing basketball yesterday.
(2) He was seen playing basketball yesterday.
句(1)中的含义不是我看见他,而是我看见他正在打篮球.playing basketball是宾语him的补足语.所以叫宾语补足语.
句(2)中的含义也不是他被看,而是别人看见他正在打篮球.这里的playing basketball是主语he的补足语,故称作主语补足语.主语和主语补足语一起称作复合主语.所以含有主语补足语的句子一般是被动语态,谓语动词是可以接复合宾语(宾语+宾语补足语)的及物动词.句首的主语就是主语补足语的逻辑主语.
二、主语补足语形式种种
1. 动词elect, call, name, make, find, leave等后面常接名词用作主语补足语.例如:
① The dog is called Karl.
② Coal is sometimes called stored-up sunlight.
③ He was found the right man for the job.
2. 动词keep, make, paint, cut, burn, beat, wash, find, consider, wipe等后面常接形容词用作主语补足语.例如:
① The door was painted white.
② The old man was found weak.
③ The classroom is always kept clean every day.
3. 动词see, watch, hear, feel, listen to, look at, imagine等后面接分词用作主语补足语.例如:
① He is often heard reading English.
② The professor was seen making an experiment in the chemistry lab.
③ The glass was found broken.
④ The classroom was found crowded with people.
4.感官动词see, watch, hear, notice, feel, make等后面接带to的不定式用作主语补足语.例如:
① He was seen to come upstairs.
② Ice is known to be in a solid state.
③ The spy was ordered to be hanged.
5. 介词短语用作主语补足语.例如:
① The books in the study must be kept in good order.
② He was found in good health.
③ English is considered of great importance for us.
6. as后面接名词、形容词、分词等用作主语补足语.例如:
① English is taken as a useful means for research work.
② The news is considered as true.
③ The stool is usually thought as having four legs
④ The vase is thought as broken.
7. 由what引导的名词性从句用作主语补足语.例如:
The boy has been made what he is.
三、 主语补足语的判别
1.看句中的动词是不是可接复合宾语,而且是不是被动语态,与此同时还要看其后部分的逻辑主语是不是句子的主语.
2. 另一种最简单的方法是:如果还不能看出来就可以把全句改成主动语态,加上一个主语we或people等.改成主动语态后,看后面是不是变成了“宾语+宾语补足语”了,这样我们就可以判别原句后面是不是主语补足语.例如:
被动句:She was found reading in the library. (主语补足语)
主动句:We found her reading in the library. (宾语+宾语补足语)
被动语态
一、 被动语态的用法:
1. 一般现在时的被动语态构成:is / am / are + 及物动词的过去分词
Our classroom is cleaned everyday.
I am asked to study hard.
Knives are used for cutting things.
2. 一般过去时的被动语态构成:was / were + 及物动词的过去分词
A new shop was built last year.
Dinosaur eggs were laid long long ago.
3. 现在完成时的被动语态构成:has / have + been + 及物动词的过去分词
This book has been translated into many languages.
Many man-made satellites have been sent up into space by many countries.
4. 一般将来时的被动语态构成:will+ be + 及物动词的过去分词
A new hospital will be built in our city.
Many more trees will be planted next year.
5. 含有情态动词的被动语态构成:情态动词+ be + 及物动词的过去分词
Young trees must be watered often.
Your mistakes should be corrected right now.
The door may be locked inside.
Your homework can be handed in tomorrow.
6. 现在进行时的被动语态构成:am / is / are + being + 及物动词的过去分词
Uncle Wang is mending my bike now.→
My bike is being repaired by Tom now.
They are planting trees over there. →
Trees are being planted over there by them.
7. 不定式的被动语态:to + be + 及物动词的过去分词
There are two books to be read. →
There are twenty more trees to be planted.
二、 怎样把主动语态改成被动语态?
把主动语态改为被动语态非常简单,可以遵循以下几个步骤:
1. 先找出谓语动词;
2. 再找出谓语动词后的宾语;
3. 把宾语用作被动语态中的主语;
4. 注意人称、时态和数的变化.
例:1. Bruce writes a letter every week. →A letter is written by Bruce every week.
2. Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.
3. He has written two novels so far.→Two novels have been written by him so far.
4. They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow.
5. Lucy is writing a letter now.→A letter is being written by Lucy now.
6. You must lock the door when you leave.→the door must be locked when you leave.
三、 使用被动语态应注意的几个问题:
1. 不及物动词无被动语态.
What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago.
2. 有些动词用主动形式表示被动意义.
This pen writes well.
This new book sells well.
3. 感官动词或使役动词使用省略to的动词不定式,主动语态中不带to ,但变为被动语态时,须加上to .
例:make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
4. 如果是接双宾语的动词改为被动语态时,直接宾语(物)作主语,那么动词后要用介词,这个介词是由与其搭配的动词决定.
He gave me a book.→A book was given to me by him.
He showed me a ticket.→A ticket was shown to me by him.
My father bought me a new bike. →A new bike was bought for me by my father.
5. 一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词.
We can’t laugh him. →He can’t be laugh by us.
He listens to the radio every day. →The radio is listened to by him every day.
The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.
补充:
系动词连接了主语和补语.这种结构中的补语是说明主语性状的,所以称为主语补足语.系动词作为实义动词的一类,具有本身的意义,但是在起到桥梁作用的同时,有些系动词会保持本身具有的意义,有些意义则会减弱或消失.例如:
1. I tasted the soup. ( taste 为及物动词,意思为“品尝”.)
2. The soup tastes wonderful. (taste 为系动词,意思为“尝起来,吃起来”,意思基本未变.)
3. He went to the cinema yesterday evening. ( go 是不及物动词,意思为“去,走”.)
4. At the news, he went mad. (go为系动词,失去了“go”的原义,意为“变得”.)
另外,英语中还有一定数量的不及物动词,完全保留了本身的词汇意义,同时又发挥着系动词的功能.它们与主语补足成分连用,所以这类词被称为“准系动词”(quasi-linking verb or half-linking verb).用于“S+Vi+Cs”(S代表主语,Vi代表不及物动词,Cs代表主语补足语)这一句式的动词都属于这种用法.有时,主语补足语不紧跟系动词,有可能被其它状语成分隔开.以“go”为例:
5. At twenty-four, Tom went half-bald. ( go 为系动词,失去原义.)
6. After midnight, Tom went home bored.( go 为准系动词,保留原义,但同时又连接主语“Tom”和主补“bored”,“home”为副词,表示地点状语.)
用于这一句式的补语可以为各种形式,如名词词组(NP),形容词词组(AP),介词词组(Pr.P),和分词短语(PP)等.现举例如下:
Type1: S + Vi +Cs (NP)
7. We parted the best friends.
= We were the best friends when we parted.
8. I stand before you today the representative of a family in grief.
= I am the representative of a family in grief when I stand before you today.
类似的动词包括: come (back), die, fall, go, leave 等.
Type2: S + Vi +Cs (AP)
9. They were born poor, lived poor, and poor they died.
= They were poor when they were born; they were poor when they lived; they were poor when they died.
10. She married young.
= She was young when she married.
11. The morning dawned fresh and clear after the storm at night.
= When the morning dawned after the storm at night, it was fresh and clear.
类似的动词包括:arrive, come (back), dawn, fall, leave, lie, marry, return, sit, stand, turn out 等.
Type3: S + Vi +Cs (Pr.P)
12. The parcel arrived in good condition.
= When the parcel arrived, it was in good condition.
13. They separated with feelings alienation.
= They had feelings alienation when they separated.
类似的动词包括:come, die, fall, go, leave, lie, part, return, sit, stand等.
Type4: S + Vi +Cs (P.P)
14. They stood listening to him.
= They stood while they were listening to him.
15. He came home convinced that she was telling the truth.
= He came home and he was convinced that she was telling the truth.
类似的动词包括:arrive, die, fall, go, leave, lie, return, sit 等.
