实意动词使用方法:
及物动词
后面必须跟宾语意义才完整的实义动词,叫做及物动词(transitive verb)。如:
I believe that the committee will consider our suggestion.我相信委员会将会考虑我们的建议。
“How long can I keep the book ?”Harry asked.哈里问:“这本书我可以借多久?”
Dr. Bethune set us a good example. 白求恩大夫给我们树立了好榜样。
Crude oil contains many useful substances.原油含有许多有用的物质。
不及物动词
本身意义完整后面不须跟宾语的实义动词,叫做不及物动词(intransitive verb)。如:
Birds fly.鸟会飞。
It happened in June 1932.这件事发生于一九三二年六月。
My watch stopped.我的表停了。
She spoke at the meeting yesterday evening. 她在昨天晚上的会上发了言。
兼作及物动词和不及物动词
英语里有不少实义动词可以兼作及物动词和不及物动词。这样的动词又有两种不同的情况
a)兼作及物动词和不及物动词时,意义不变。试比较:
Shall I begin at once?我可以立刻开始吗?(begin作不及物动词)
She began working as a librarian after she left school.她毕业后当图书馆管理员。(began作及物动词)
When did they leave Chicago?他们是什么时候离开芝加哥的?(leave 作及物动词)
They left last week. 他们是上周离开的。(left 作不及物动词)
b)兼作及物动词和不及物动词时,有时意义不尽相同。如:
Wash your hands before meals.饭前要洗手。
Does this cloth wash well? 这布经得起洗吗?
实意动词的用法:
肯定句:
主语+动词过去式+其它
否定句:
主语+助动词didn‘t+动词原型+其他
一般过去式:
Did+主语+动词原型+其他
系动词使用的注意事项:
系动词本身有一定的词义,不能单独作谓语,后面必须与表语连用。复习系动词时,必须注意以下几个问题:
1.be是最重要的系动词,主语不同,be的形式也不同,且有时态的变化。
a通常表示主语的特征、状态和身份等,后面接形容词、副词、名词、介词短语、不定式、v-ing、过去分词及表语从句作表语。
b特别要注意“由be+过去分词”所构成的系表结构与“由be+过去分词”所构成的被动语态的区别。
c前者侧重于表示主语的特征或所处的状态,通常没有由by引导的介词短语。
如:The door was closed.
后者侧重于强调主语是谓语动词所示动作的承受者,表示动作;句中可以用由by引导的介词短语。如:The door was closed by me.
d还要注意“由be+ V-ing所构成的系表结构与“由be+ V-ing”所构成的进行时态的区别。
前者侧重于说明主语具有的特征或存在的状态,也可说明主语是什么。如:My job is teaching English.
后者侧重于强调主语正在做某事。如:Mr Wang is reading an evening paper now.
2. 要注意由行为动词转化成的系动词。
a表示人体感官的系动词有sound,taste,look,feel,smell等,后面接形容词;
b表示主语从一种状态转变到另一种状态的系动词有become,get,go,turn,run,grow,come,fall,prove等,后面接形容词、名词或 to be+形容词,become后面接单数名词时,名词前要用不定冠词,turn后面接单数名词时,名词前不用不定冠词;
c表示主语继续或保持某种身份、特征或状态的系动词有continue,keep,remain,stay,stand lie,rest,stay等,后面接表示状态的形容词;
d表示判断的系动词有seem和appear,后面接形容词、to be+名词或形容词、that-clause、不定式等。
3. 要注意系动词的固定搭配。常见的有come true, fall asleep, fall ill, go bad, come right, run wild, wear thin, turn nasty等。
4.要特别注意某些动词既可以做系动词,又可以做实意动词的用法。
系动词部分主要注意:
其后要求接形容词,而不是副词做表语。遇到这种情况,只能先根据其意思判断清楚到底是前者还是后者,然后再对后面的词性和词义做出正确判断和选择。
以taste一词为例:
The newly-invented soft drinking tastes quite unique.
(这种新研制的软饮料尝起来挺独特的。
注意:在这句话里,taste做系动词,不能使用进行时,后面接形容词。)
The chef is tasting the fish carefully.
(厨师长正在品尝这道鱼。
注意:在这句话中,taste做实意动词,可以使用进行时,并且后面接副词做状语。)
系动词用法点拨:
1.系动词的进行时态应分情况讨论。
一般地说,状态系动词无进行时态,而动态系动词有进行时态。
但是在某些情况下,状态系动词也有进行时态,表示两个用途:
一是表示一种短暂的、反常的状态。如:
He is being kind.(一时而不能持久的性质)他装出和蔼可亲的样子。
二是表示一种探询口气,使语言客气、生动、亲切。例如:
I hope you are keeping well.(语气委婉)我希望你保持健康。
Are you feeling any better?(语气亲切)你感觉好了些吗?
试比较:
Your hand feels cold.(无意识的静态性质。)你的手摸起来冰凉。
不可以说:
Your hand is feeling cold.(×)
但可以说:
The doctor is feeling her pulse.(有意识的动态动作)医生正在给她拿脉。
The soup tastes good.(静态性质,无进行时)这汤的味道不错。
The cook is tasting the soup.(动态动作,有进行时)厨师在尝汤的味道。
总之,系动词有无进行时态应随系动词的意义或其语境变化而变化。
我们在概述某一动词的进行时态时,不能笼统地说feel,smell无进行时,应指出其意义及其语用环境。
例如smell的用法可见一斑。
①smell作“嗅觉”的能力时,虽是实义动词,但指的是一种性质的存在状态不能用于进行时态,常与can, could, be able to连用。
The camels can smell the water a mile off.骆驼能嗅出一英里外有水。
②指“嗅、闻”的动作时,实义动词,可用于进行时态。
The girl is smelling the flower.这姑娘正在闻那朵花。
③smell指“含有……气味”,“发出……气味”等事物性质时,半系动词,无进行时态。
The dinner smells good.这饭菜闻起来真香。
2.系动词的时态与形容词的比较级连用的问题。
某些含有变化意义的动态系动词如get, become, grow, turn等的进行时态可与形容词的比较级连用,表示渐进过程,其意思是“越来越……”。例如:
He is growing taller and taller.他长得越来越高了。
Our life is getting better and better.我们的生活是越来越好了。
The things are getting worse.情况是越来越糟了。
3.所有半系动词的被动语态要分情况讨论。
英语中某动词在作系动词用时,无被动语态,而作实义动词用时,才有被动语态,二者不可混为一谈。例如:
不能说:
The apple is tasted good.
(因为taste此时是系动词,“尝起来”之意,指的是苹果的性质,无被动语态)
但我们可以说:
The apple is tasted by me.这苹果被我尝了一下。
(taste此时指“尝一尝”这一动作,有被动语态)
因此,在平时的英语教学和学习之 ,要有意注意半系动词在具体的语言环境中到底是系动词用法还是实义动词用法,要注意区分、识别。
4.瞬间动态系动词能否与时间段连用的问题
英语中某些表示瞬间意义的系动词不能与“for+时间段,since+时间点,how long until+时间,by + 时间,so far”等直接连用。例如:
①不能说:He has become a teacher for 2 years.
应改为:He has been a teacher for 2 years.
②不能说:He has turned writer since 3 years ago.
应改为:He has been a writer since 3 years ago.
或It is three years since he turned writer.
③不能说:He got angry until his child came back home.
应改为:He didn’t get angry until his child came back home.
5.系动词能接几种表语(从句)
系动词除了接adj.
.prep.短语,某些adv.以外,还可接以下几种表语形式:
①能接as if/as though表语从句的系动词有:look(看起来),smell(闻起来),sound(听起来),feel(觉得);appear(显得),seem(似乎)。例如:
It looks as if we are going to have snow.看样子天要下雪了。
He looked as if he had just stepped out of my book of fairy tales.
他看来好像刚从我的童话故事中走出来似的。
She seemed as if (though) she couldn’t understand why Laura was there.
看来她好像不能理解为什么劳拉呆在那儿。
It sounds to me as though there’s a tap running somewhere.
我好像听到某处水龙头流水的声音。
She felt as if her head were splitting.
她仿佛觉得她的头要裂开了。
The river appeared as if enveloped in smog.
那条河好像笼罩在烟雾之中。
It seems as if it were spring already.
好像已是春天了。
②可用于“It+系动词+that从句”结构的有:seem, appear, 不可用be, look。如:
It seemed that he had made some serious mistakes in his work.
好像他在工作中犯了严重错误。
It appeared that he was talking to himself.
好像他在自言自语。
③能用不定式作表语的系动词有:be, seem, get, look, appear, prove, grow.
Her job is to look after the children.
她的工作是照料孩子们。
He seems not to look after the children.
他好像不是她的父亲。
She looks to be a young girl of twenty year-old.
她看起来像是一个20岁的年轻姑娘。
He didn’t appear to dislike it.
看不出他憎恨此事。
My advice proved to be wrong.
我的建议证明是错误的。
He will grow to like this work gradually.
他会逐渐喜欢这个工作的。
④能与there连用的系动词有:be, appear, seem.
There appeared to be only one room.
那儿好像只有一个房间。
There seems(to be)no need to go.
似乎没有必要走。
6.能用两种否定形式的系动词有两个:seem, appear.
举例说明:
It doesn’t seem that we can get our money back.= It seems that we can’t get our money back.
He seems not to be her father.= He doesn’t seem to be her father.
The baby doesn’t appear to be awake.= The baby appears not to be awake.
7.后接作表语的过去分词可构成系表结构
能构成系表结构的系动词通常有两个:第一个是常见的be(is, am, was等);第二个是get,口语中常用。
当二者作系动词用时,它们均表示一种存在状态,而不表示被动动作;当二者作助动词用时,后接作谓语的过去分词构成被动语态。
Be + P.P常可以用get + P.P.来代替,但是并不是be系动词总是可以用get来代替。Get + P.P.系表结构常用于以下两种情况:
1)表示偶然的、突发性的、意想不到的被动动作的结果或状态。
Last night I got caught in the downpour.昨夜我被雨淋了(表示意想不到)
The new car got scratched.新车给刮坏了。(表突发性)
2)表示对自身所作的事。如get dressed, get lost等。
John got injured while playing football last Saturday.约翰上周星期六踢足球时受了伤。
They got married last month.他们上个月结婚了。
另外,要注意区分系表结构与被动语态结构的用法。
常见助动词用法:
have的用法:
have作助动词
形式:
主要变化形式:have,has,had
动名词/现在分词:having
1)have +过去分词,构成完成时态,例:
He has left for London. 他已去了伦敦。
By the end of last month, they had finished half of their work.
上月末为止,他们已经完成工作的一半。
2)have + been +现在分词,构成完成进行时(现在完成时),例:
I have been studying English for ten years.我一直在学英语,已达十年之久。
3)have+been +过去分词,构成完成时态的被动语态,例:
English has been taught in China for many years.中国教英语已经多年。
do的用法:
形式
主要变化形式:do,did,done
动名词/现在分词:doing
1) 构成一般疑问句,例如:
Do you want to pass the CET?你想通过大学英语测试吗?
Did you study German? 你们学过德语吗?
2)do + not 构成否定句,例如:
I do not want to be criticized.我不想挨批评。
He doesn't like to study.他不想学习。
In the past, many students did not know the importance of English.过去,好多学生不知道英语的重要性。
3) 构成否定祈使句,例如:
Don't go there. 不要去那里。
Don't be so absent-minded. 不要这么心不在焉。
说明: 构成否定祈使句只用do,。
4)放在动词原形前,加强该动词的语气,例如:
Do come to my birthday party please.请一定来参加我的生日宴会。
I did go there. 我确实去那儿了。
I do miss you. 我确实想你。我真想你了!
5)用于倒装句,例如:
Never did I hear of such a thing.
我从未听说过这样的事情。
Only when we begin our college life do we realize the importance of English.
只有在开始大学生活时我们才认识到英语的重要性。
说明: 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。
6)用作代替动词,例如:
Do you like Beijing? 你喜欢北京吗?
Yes,I do.是的,喜欢。(do用作代动词,代替like Beijing.)
He knows how to drive a car, doesn't he?他知道如何开车,对吧?
may和can:
1) may用来表示许可
2)may用于所有人称的现在时及将来时句子中。
3)might用于所有人称的过去时及条件句中。
否定形式:may not/mayn't,might not/mightn't
疑问式:may I?might I?等
否定疑问式:may I not?/mayn't I?等
表示许可的may的其他形式可用allow,be allowed的相应形式代替。
4)may后面接不带to的不定式(即动词原形)。
5)can用来表示许可
6)can用于所有人称的现在时及将来时的句子中。
7)could用于所有人称的过去时及条件句中。
否定式:can not/can't,could not/could't
疑问式:can I?could I?等。
否定疑问式:can I not?/can't I?could I not?/couldn't I?等。
表示许可的can的其他形式可用于allow,be allowde的相应形式代替。
can与不带to的不定式连用。
shall和will的用法:
1)shall和will作为助动词可以与动词原形一起构成一般将来时,例如:
I shall study harder at English.我将更加努力地学习英语。
He will go to Shanghai. 他要去上海。
说明:
在过去的语法中,语法学家说shall用于第一人称,will 只用于第二、第三人称。
现在,尤其是在口语中,will常用于第一人称,但shall只用于第一人称,如用于第二、第三人称,就失去助动词的意义,已变为情态动词,试比较:
He shall come.他必须来。(shall有命令的意味。)
He will come.他要来。(will只与动词原形构成一般将来时。)
2)shall在疑问句中,用于第一,第三人称,征求对方意愿
shall I turn on the light?
要开灯吗?( 我把灯打开好吗?)
shall he come to see you?
他要不要来看你
(比较: will he come to see you? 他会不会来看你)
3)shall 用在陈述句,与第二第三人称连用,变为情态动词,表示允诺,命令,警告,和说话人的决心等。
should,would的用法:
1)should无词义,只是shall的过去形式,与动词原形构成过去将来时,只用于第一人称,例如:
I telephoned him yesterday to ask what I should do next week.
我昨天给他打电话,问他我下周干什么。
比较:
"What shall I do next week?" I asked.
"我下周干什么?"我问道。(可以说,shall变成直接引语时,变成了should。)
2)would也无词义,是will的过去形式,与动词原形构成过去将来时,用于第二、第三人称,例如:
He said he would come.他说他要来。
比较:
"I will go," he said. 他说:"我要去那儿。"
变成间接引语,就成了:
He said he would come.
原来的will变成would,go变成了come.。过去式从原来的go变为came。
动词短语与短语动词:
(2)同一个动词后面可以有不同的副词性小品词,构成不同意义的短语动词。如:He turn on the radio .Bob turned out smiling.
(3)短语动词用法普遍,尤其在非正式语言中:
我们可以说 He awoke late the following morning .但这太正式了。
我们通常说 He woke up late the following morning .

介词at, in, on的区别:
1. 表示时间,注意以下用法:
(1) 表示时间的某一点、某一时刻或年龄等用 at。如:
I get up at six in the morning. 我早上六点钟起床。
He got married at the age of 25. 他 25 岁结婚。
(2) 泛指一般意义的上午、下午或晚上以及月或年等较长的时间,一般用 in。如:
We watch TV in the evening. 我们晚上看电视。
He went to Japan in 1946. 他于 1946 去了日本。
(3) 若表示星期几或某一特定的日期,则用 on。如:
He left here on the fifth of May. 他于 5 月 5 日离开这儿。
2. 表示地点、场所、位置等,注意以下用法:
(1) 表示某一点位置,用 at。如:
We live at No 87 Beijing Road. 我们住在北京路 87 号。
The hospital is at the end of the street. 医院在这条街的尽头。
与名词所有格连用表示地点,也用 at。如:
at my sister’s 在我姐姐家 at the doctor’s 在医务室
(2) 表示空间或范围,用 in。如:
What’s in the box? 这盒子里有什么?
He lives in Paris with his wife. 他同他妻子住在巴黎。
但有时两者可换用。如:
The meeting was held at [in] the hotel. 会议在宾馆举行。
(3) at 与 in 的另一个区别是:at 用于指较小的地方,而 in 用于指较大的地方。如:
in Shanghai 在上海 at the station 在车站
但是,大与小是相对的,有时随着说话者的着眼点不同,大地方也可能用 at(比如把一个大地方看作一个点时)。如:
Our plane refuelled at London. 我们的飞机在伦敦加油。
We stopped for an hour at Moscow on our way to Paris. 我们在去巴黎的途中在莫斯科停了 1 个小时。
(4) 介词 on 用于地点,主要指在某物的表面。如:
What’s on the table? 桌上有什么?
There’s a wallet lying on the ground. 地上有个钱包。
注:在少数搭配中,也用介词 on。如:
He works on a farm. 他在农场工作。
3. 在某些搭配中,三者的区别与英国英语和美国英语有关:
in the street (英) / on the street (美) 在街上
in the road (英) / on the road (美) 在路上
in the team (英) / on the team (美) 在这个队
at the weekend (英) / on the weekend (美) 在周末
at weekends (英) / on weekends (美) 在周末
4. 有时三者的差别与搭配习惯和用法有关:
in bed / on the bed 在床上
in the tree (多指树外之物) / on the tree (多指树本身之物) 在树上
介词besides,but,except的用法区别:
1. 三者都可表示“除外”,但 besides 表示一种累加关系,意指“除了什么之外,还有……”;
而 except 或 but 则表示一种排除关系,意指“除了什么之外,不再有……”。如:
Besides his wife,his daughter also went to see him. 除他妻子外,他女儿也去看过他(即妻子女儿都去看过他)。
Nobody went to see him except [but] his wife. 除他妻子外,没有一个人看过他(即只有他妻子去看过他)。
注:在否定句中,besides 也表示“除……之外不再有…… ”,与but, except 同义。如:
No one passed the exam besides [except] Jim. 除吉姆外,没一个人通过考试。
2. 关于 but 与 except:
(1) 两者都可表示“除……外不再有……”,但含义上略有差别:
but侧重指意义的几乎完整性,而 except 则侧重指后面除去的部分。比较:
All are here but one. 除一个人都到了。
All are here except one. 还有一个人没到。
(2) 在现代英语中,but 的介词用法十分有限,一般说来,它只能用在下列词语之后:
① no, no one, nobody, nothing, nowhere 等
② any, anyone, anybody, anything, anywhere 等
③ every, everyone, everybody, everything, everywhere 等
④ all, none 等
⑤ who, what, where 等
Everyone knows it but you. 除你之外大家都知道。
I haven’t told anybody but you. 除你之外,我没告诉任何人。
No one but he [him] showed much interest in it. 除他之外没有一个人对此有很大兴趣。
一般说来,若没有出现上述词汇,就不宜使用介词 but,否则可能造成错句。但是 except 却没有以上限制。比较:
正:The window is never opened except in summer. 除夏天外,这扇窗户从不打开。
误:The window is never opened but in summer.
(3) but 一定不能用于句首,except 通常不用于句首:
除我之外每个人都累了。
正:Everyone is tired but (except) me.
正:Everyone but (except) me is tired.
误:But (Except) me, everyone is tired.
注:except for 可用于句首,表示 except 的意思:
正:Except for me, everyone is tired.
3. 关于 except 与 except for:
except 主要用来谈论同类的东西,而 except for 则主要用来谈论不同类的东西,有时含有惋惜之意。如:
All compositions are well written except yours. 除了你的作文外,其他的作文都写得很好。
His composition is good except for a few spelling mistakes. 他的作文写得不错,只是有几处拼写错误。
注:若用于句首,则 except for 与 except 同义(但 except 通常不用于句首)。
4. 关于 except for 与 but for:
except for 主要表示排除,but for 主要表示一种虚拟条件(与虚拟语气连用)。如:
Except for me, everyone passed the exam. 除了我之外,大家都通过了考试。
But for my help, she would not have passed the exam. 若不是我的帮助,她就不会通过考试。
But for the atmosphere plants would die. 如果没有大气,植物就会死亡。
5. besides 除用作介词外,还用作副词,其意为“此外”、“而且”,可用于分句句首(通常用逗号隔开)或句尾。如:
I don’t want to go; besides, I’m too tired. 我不想去,而且我也太累了。
This car belongs to Smith, and he has two others besides. 这部车是史密斯的,此外他还有两部。

宾语从句的特点:
1.宾语从句可以作及物动词、介词及形容词的宾语。
2.宾语从句的语序一律用陈述句语序。
3.连接词that引导宾语从句在句中无词义,不充当句子成份,多数情况下可以省略。
4.whether 和 if 都可引导宾语从句,但 whether后可紧跟or not;whether从句可作介词的宾语。
5.如果从句太长,可以用形式宾语it.
宾语从句的时态:
1.主句是一般现在时,从句根据实际情况使用任何时态。
例句:The headmaster hopes everything goes well.
2.主句是过去时态,从句须用过去时态的某种形式。
例句:She was sorry that she hadn’t finished her work on time.
3.当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态。
例句:The teacher told his class that light travels faster than sound.
4. 如果从句的动作发生在主句之前,则从句要用过去完成时态。
宾语从句的语序:
A. 宾语从句必须用陈述语序。
False: He is wondering when can he finish this difficult job.
Right: He is wondering when he can finish this difficult job.
B. 有时候可以用it 作形式宾语,而把真正的宾语从句放在后面。
Bad: I thought that he could finish this job in just two hours impossible.
Good: I thought it impossible that he could finish this job in just two hours.
C. 带有宾语从句的复合句的否定形式一般是否定主句。
Bad: I think he doesn’t like the English teacher.
Good: I don’t think he likes the English teacher.
D. 主句一般过去时态,从句也要用过去时态。
False: He wanted to know why he is crying in the corner.
Right: He wanted to know why he was crying in the corner
宾语从句的否定转移:
主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等。
并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致。
I don’t think he will come to my party.而不能说成I think he won’t come to my party.
我认为他不会来我的舞会.
I don’t believe that man is killed by Jim,is he?
我认为那个人不是Jim所杀的,是不是?
如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式。
We find that he never listens to the teacher carefully,does he?
我们发现他从来不仔细听老师讲课,是不是?
宾语从句中引导词的用法比较
在复合句中作主句的宾语,引导词有:
连词:that (that 常可省略),whether, if
代词:who, whose, what ,which
副词:when ,where, how, why 等。
(一)that引导的宾语从句(在非正式场合that可以省略)
1.可跟that从句做宾语的动词有:
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句:The boy believes that he will travel through space to other planets.
注意事项:当主句谓语动词是 think, believe, suppose, expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示。
例句:I don’t think it is right for him to treat you like that.
2.在以下情况中that不能省略
a.当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省。
例句:He said (that) you were too young to understand the matter and that he was asked not to tell you.
b.当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省。
例句:Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
c.当that从句是双宾语中的直接宾语时,that不可省。
例句:I can’t tell him that his mother died.
d.注:许多带复合宾语的句子,that引导的宾语从句经常移到句子后部,而用it作形式宾语。
例句:I find it necessary that we should do the homework on time.
(二)由whether,if 引导的宾语从句
1.由whether(if)引导的宾语从句,实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。
一般说来,在宾语从句中whether与if可以互换使用,但在特殊情况下if与whether是不能互换的。
例句:I wonder whether(if) they will come to our party.
2.只能用whether,不能用if引导的宾语从句
a.在带to的不定式前
例句:We decided whether to walk there.
b.在介词的后面
例句:I’m thinking of whether we should go to see the film.
c.在动词后面的宾语从句时
例句:We discussed whether we had a sports meeting next week
d.直接与or not连用时
例句:I can’t say whether or not thet can come on time.
3.只能用if不能用whether引导的宾语从句
a.if引导条件状语从句,意为“如果”
例句:The students will go on a picnic if it is sunny.
b.if引导否定概念的宾语从句时
例句:He asked if I didn’t come to school yesterday.
c.引导状语从句even if(即使)和as if(好象)时
例句:He talks as if he has known all about it.
if,whether在宾语从句中的区别
a.if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if
b.少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.
c. whether后可以加or not,但是if不可以.
d.在不定式前只能用whether.
(如:I can’t decide whether to stay. 我不能决定是否留下。)
e.避免歧异时,我们常用whether而不用if.
(三)连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句要用陈述句语序。
用于这种结构的动词常常是:see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
1.英语中的连接代词有:who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。
例句:Can you tell me whom you are waiting for?
2.英语中的连接副词有:when,where,why,how,在句中担任状语的成分。
例句:None of us knows where these new parts can be bought.
简化宾语从句常用六法:
方法一:
当主句谓语动词是hope, decide, wish, choose, agree, promise等,
且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。
例如:
Li Ming hopes he will be back very soon.
→Li Ming hopes to be back very soon.
We decided that we would help him.
→We decided to help him.
方法二:当主句谓语动词是know, learn, remember, forget, tell等动词,
且主句主语与从句主语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
She has forgotten how she can open the window.
→She has forgotten how to open the window.
注:当主句谓语动词是tell, ask, show, teach等动词,
且后带双宾语,从句主语和间接宾语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
Could you tell me how I can get to the station?
→Could you tell me how to get to the station?
方法三:当主句的谓语动词是order(命令),require(需要)等时,
如果主句和从句的主语不一致,宾语从句可简化为“名词(代词)+不定式”结构。例如:
The headmaster ordered that we should start at once.
→ The headmaster ordered us to start at once.
方法四:某些动词后的宾语从句,可以用介词加动名词(短语)等其他形式简化。例如:
He insisted that he should go with us.
→He insisted on going with us.
The poor boy doesn’t know when and where he was born.
→The poor boy doesn’t know the time and the place of his birth.
方法五:某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。例如:
Liu Ping found that there was a wallet lying on the ground.
→ Liu Ping found a wallet lying on the ground.
方法六:动词seem后的宾语从句,也可以用不定式(短语)来简化,但句型需要进行适当的变化。例如:
It seemed that the boys were going to win.
→The boys seemed to win.
除上述方法外,还有一些特殊句式的转化。例如:
I found that it was difficult to learn English well.
→I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow.
→Soon we found the ground covered with thick snow.
They found that the box was very heavy.
→They found the box very heavy
