就是非谓语动词,从句,倒装一类的,谢谢了^^
第1个回答 2008-02-02
1.非谓语动词:
在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词)。
1)不定式
时态\语态 主动 被动
一般式 to do to be done
完成式 to have done to have been done
2)动名词
时态\语态 主动 被动
一般式 doing being done
完成式 having done having been done
3)分词
时态\语态 主动 被动
一般式 doing being done
完成式 having done having been done
否定形式: not +不定式, not + 动名词, not + 现在分词
2.从句
从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。
主语从句用作主语,如::
That the earth is round is true. 地球为圆的是真实的。
宾语从句用作宾语。如:
Do you know where he lives?
表语从句用作表语,如:
My opinion is that you should not go alone. 我的意见是你不应单独前往。
同位语从句用于解释说明前面的名词。如:
The fact that the earth is round is true. 地球是圆的的事实是真实的。(that从句用于解释说明the fact)
定语从句相当于一个形容词,用于修饰前面的名词。如:
The student who answered the question was John. 回答问题的学生是John.
状语从句相当于一个副词,如:
When it rains, I usually go to school by bus. 天下雨时,我通常坐公共汽车上学。(时间状语)
If he comes tomorrow, you will see him. 如果他明天来,你就可以看见他。(if 引导的条件状语从句,其结构为:if +状语从句,+主句)。要注意在状语从句中有一个规则是“主将从现”,即主句是将来时,则从句要用一般现在时表示将来。
主句和从句的划分方法是相同的。句子的成分从谓语动词处来划分比较容易。谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语。如:
I am a teacher. 其中,I 是主语,am是谓语,a teacher 是表语。
He likes playing football very mucy. 其中,he是主语,likes是谓语,playing football是宾语,very much是状语。
3.倒装:
倒装句(Inversion)
英语的基本语序是“主语+谓语”。如果将谓语的全部或一部分放在主语之前,这种语序称为“倒装”。
一、倒装的类型

完全倒装
Out rushed the students to welcome the foreign friends.
学生们涌出去欢迎外国朋友。 整个谓语移至主语之前。
部 分 倒 装

so\neither\nor+助动词\情态动词等+主语
2.由there\here引导的倒装句.(例子见上)
在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词)。

第2个回答 2008-02-02
非谓语动词
在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词)。
1)不定式
时态\语态 主动 被动
一般式 to do to be done
完成式 to have done to have been done
2)动名词
时态\语态 主动 被动
一般式 doing being done
完成式 having done having been done
3)分词
时态\语态 主动 被动
一般式 doing being done
完成式 having done having been done
否定形式: not +不定式, not + 动名词, not + 现在分词
倒装句之全部倒装
全部倒装是只将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和 一般过去时。常见的结构有:
1) here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。
There goes the bell.
Then came the chairman.
Here is your letter.
2) 表示运动方向的副词或地点状语置于句首,谓语表示运动的动词。
Out rushed a missile from under the bomber.
Ahead sat an old woman.
注意:上述全部倒装的句型结构的主语必须是名词,如果主语是人称代词则不能完全倒装。
Here he comes. Away they went.
倒装句之部分倒装
部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词,则需添加助动词do, does或did,并将其置于主语之前。
1) 句首为否定或半否定的词语,如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。
Never have I seen such a performance.
Nowhere will you find the answer to this question.
Not until the child fell asleep did the mother leave the room.
当Not until引出主从复合句,主句倒装,从句不倒装。
注意: 如否定词不在句首不倒装。
I have never seen such a performance.
The mother didn't leave the room until the child fell asleep.
典型例题
1) Why can't I smoke here?
At no time___ in the meeting-room
A. is smoking permitted B. smoking is permitted
C. smoking is it permitted D. does smoking permit
答案A. 这是一个倒装问题。当否定词语置于句首以表示强调时,其句中的主谓须用倒装结构。 这些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.
2) Not until the early years of the 19th century ___ what heat is.
A. man did know B. man know C. didn't man know D. did man know
答案D. 看到Not until…的句型,我们知道为一倒装句,答案在C,D 中选一个。
改写为正常语序为,Man did not know what heat is until the early years of the 19th. 现在将not提前,后面就不能再用否定了,否则意思就变了。
以否定词开头作部分倒装
如 Not only…but also, Hardly/Scarcely…when, No sooner… than
Not only did he refuse the gift, he also severely criticized the sender.
Hardly had she gone out when a student came to visit her.
No sooner had she gone out than a student came to visit her.
典型例题
No sooner___ than it began to rain heavily.
A. the game began B. has the game begun
C. did the game begin D. had the game begun
答案D. 以具有否定意义的副词放在句首时,一般采用倒装句(谓语前置)。这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when 等等。
注意:只有当Not only… but also连接两个分句时,才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语,不可用倒装结构。
Not only you but also I am fond of music.
so, neither, nor作部分倒装
表示"也"、"也不" 的句子要部分倒装。
Tom can speak French. So can Jack.
If you won't go, neither will I.
典型例题
---Do you know Jim quarrelled with his brother?
---I don't know, _____.
A. nor don't I care B. nor do I care C. I don't care neither D. I don't care also
答案:B. nor为增补意思"也不关心",因此句子应倒装。A错在用 don't 再次否定, C neither 用法不对且缺乏连词。 D缺乏连词。
注意: 当so引出的句子用以对上文内容加以证实或肯定时,不可用倒装结构。意为"的确如此"。
Tom asked me to go to play football and so I did.
---It's raining hard. ---So it is.
only在句首要倒装的情况
Only in this way, can you learn English well.
Only after being asked three times did he come to the meeting.
如果句子为主从复合句,则主句倒装,从句不倒装
Only when he is seriously ill, does he ever stay in bed.
as, though 引导的倒装句
as / though引导的让步从句必须将表语或状语提前 (形容词, 副词, 分词, 实义动词提前)。
注意:
1) 句首名词不能带任何冠词。
2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语, 随实义动词一起放在主语之前。
Try hard as he will, he never seems able to do the work satisfactorily.
注意:
让步状语从句中,有though,although时,后面的主句不能有but,但是 though 和yet可连用。
其他部分倒装
1) so… that 句型中的so 位于句首时,需倒装。
So frightened was he that he did not dare to move an inch.
2) 在某些表示祝愿的句型中:
May you all be happy.
3) 在虚拟语气条件句中从句谓语动词有were, had, should等词,可将if 省略,把 were, had, should 移到主语之前,采取部分倒装。
Were I you, I would try it again.
典型例题:
1) Not until the early years of the 19th century___ what heat is
A. man did know B. man knew C. didn't man know D. did man know
答案为D. 否定词Not在句首,要求用部分倒装的句子结构。
2) Not until I began to work ___ how much time I had wasted.
A. didn't I realize B. did I realize C. I didn't realize D. I realize
答案为B。
3) Do you know Tom bought a new car?
I don't know, ___.
A. nor don't I care B. nor do I care
C. I don't care neither D. I don't care also
解析:答案为B. 句中的nor引出部分倒装结构,表示"也不"。由 so, neither, nor引导的倒装句,表示前一情况的重复出现。其中, so用于肯定句, 而 neither, nor 用在否定句中。
名词性从句
在句子中起名词作用的句子叫名词从句 (Noun Clauses)。 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的连接词
引导名词性从句的连接词可分为三类:
连接词:that,whether,if 不充当从句的任何成分)
连接代词:what, whatever, who, whoever, whom,
whose, which.
连接副词:when, where, how, why
不可省略的连词:
1. 介词后的连词
2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.
We heard the news that our team had won.
比较:whether与if 均为"是否"的意思。 但在下列情况下,whether 不能被if 取代:
1. whether引导主语从句并在句首
2. 引导表语从句
3. whether从句作介词宾语
4. 从句后有"or not"
Whether he will come is not clear.
大部分连接词引导的主语从句都可以置于句末,用 it充当形式主语。
It is not important who will go.
It is still unknown which team will win the match.
名词性that-从句
1)由从属连词that引导的从句叫做名词性that-从句。 That只起连接主句和从句的作用,在从句中不担任任何成分,本身也没有词义。名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语,例如:
主语:That he is still alive is sheer luck. 他还活着全靠运气。
宾语:John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。
表语:The fact is that he has not been seen recently. 事实是近来谁也没有见过他。
同位语:The fact that he has not been seen recently disturbs everyone in his office.
近来谁也没有见过他,这一事实令办公室所有的人不安。
形容词宾语:I am glad that you are satisfied with your job.
你对工作满意我感到很高兴。
2)That-从句作主语通常用it作先行词,而将that-从句置于句末,例如:
It is quite clear that the whole project is doomed to failure. 很清楚,整个计划注定要失败。
It's a pity that you should have to leave. 你非走不可真是件憾事。
用it作形式主语的that-从句有以下四种不同的搭配关系:
a. It + be +形容词+ that-从句
It is necessary that… 有必要……
It is important that… 重要的是……
It is obvious that… 很明显……

名词性wh-从句
1)由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外,还可充当介词宾语、宾语补语和间接宾语等,例如:
主语: How the book will sell depends on its author. 书销售如何取决于作者本人。
直接宾语:In one's own home one can do what one likes. 在自己家里可以随心所欲。
间接宾语:The club will give whoever wins a prize.
俱乐部将给得胜者设奖。
表语: My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。
宾语补足语:She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。
同位语: I have no idea when he will return.
我不知道他什么时候回来。
形容词宾语:I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。
介词宾语: That depends on where we shall go.
那取决于我们去哪儿。
2)Wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末,例如:
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married. 他们何时结婚依然不明。
if, whether引导的名词从句
1)yes-no型疑问从句
从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,因此也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同, 例如:
主语:Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。
宾语:Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。
表语:The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。
同位语:They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。
形容词宾语: She's doubtful whether we shall be able to come. 她怀疑我们是否能够前来。
介词宾语: I worry about whether he can pass through the crisis of his illness. 我担心他是否能度过疾病的危险期。
2)选择性疑问从句
选择性疑问从句由关联词if/whether…or或whethe…or not构成,例如:
Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。
I don't care whether you like the plan or not.我不在乎你是否喜欢该计划。本回答被提问者采纳
在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词)。
1)不定式
时态\语态 主动 被动
一般式 to do to be done
完成式 to have done to have been done
2)动名词
时态\语态 主动 被动
一般式 doing being done
完成式 having done having been done
3)分词
时态\语态 主动 被动
一般式 doing being done
完成式 having done having been done
否定形式: not +不定式, not + 动名词, not + 现在分词
倒装句之全部倒装
全部倒装是只将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和 一般过去时。常见的结构有:
1) here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。
There goes the bell.
Then came the chairman.
Here is your letter.
2) 表示运动方向的副词或地点状语置于句首,谓语表示运动的动词。
Out rushed a missile from under the bomber.
Ahead sat an old woman.
注意:上述全部倒装的句型结构的主语必须是名词,如果主语是人称代词则不能完全倒装。
Here he comes. Away they went.
倒装句之部分倒装
部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词,则需添加助动词do, does或did,并将其置于主语之前。
1) 句首为否定或半否定的词语,如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。
Never have I seen such a performance.
Nowhere will you find the answer to this question.
Not until the child fell asleep did the mother leave the room.
当Not until引出主从复合句,主句倒装,从句不倒装。
注意: 如否定词不在句首不倒装。
I have never seen such a performance.
The mother didn't leave the room until the child fell asleep.
典型例题
1) Why can't I smoke here?
At no time___ in the meeting-room
A. is smoking permitted B. smoking is permitted
C. smoking is it permitted D. does smoking permit
答案A. 这是一个倒装问题。当否定词语置于句首以表示强调时,其句中的主谓须用倒装结构。 这些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.
2) Not until the early years of the 19th century ___ what heat is.
A. man did know B. man know C. didn't man know D. did man know
答案D. 看到Not until…的句型,我们知道为一倒装句,答案在C,D 中选一个。
改写为正常语序为,Man did not know what heat is until the early years of the 19th. 现在将not提前,后面就不能再用否定了,否则意思就变了。
以否定词开头作部分倒装
如 Not only…but also, Hardly/Scarcely…when, No sooner… than
Not only did he refuse the gift, he also severely criticized the sender.
Hardly had she gone out when a student came to visit her.
No sooner had she gone out than a student came to visit her.
典型例题
No sooner___ than it began to rain heavily.
A. the game began B. has the game begun
C. did the game begin D. had the game begun
答案D. 以具有否定意义的副词放在句首时,一般采用倒装句(谓语前置)。这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when 等等。
注意:只有当Not only… but also连接两个分句时,才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语,不可用倒装结构。
Not only you but also I am fond of music.
so, neither, nor作部分倒装
表示"也"、"也不" 的句子要部分倒装。
Tom can speak French. So can Jack.
If you won't go, neither will I.
典型例题
---Do you know Jim quarrelled with his brother?
---I don't know, _____.
A. nor don't I care B. nor do I care C. I don't care neither D. I don't care also
答案:B. nor为增补意思"也不关心",因此句子应倒装。A错在用 don't 再次否定, C neither 用法不对且缺乏连词。 D缺乏连词。
注意: 当so引出的句子用以对上文内容加以证实或肯定时,不可用倒装结构。意为"的确如此"。
Tom asked me to go to play football and so I did.
---It's raining hard. ---So it is.
only在句首要倒装的情况
Only in this way, can you learn English well.
Only after being asked three times did he come to the meeting.
如果句子为主从复合句,则主句倒装,从句不倒装
Only when he is seriously ill, does he ever stay in bed.
as, though 引导的倒装句
as / though引导的让步从句必须将表语或状语提前 (形容词, 副词, 分词, 实义动词提前)。
注意:
1) 句首名词不能带任何冠词。
2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语, 随实义动词一起放在主语之前。
Try hard as he will, he never seems able to do the work satisfactorily.
注意:
让步状语从句中,有though,although时,后面的主句不能有but,但是 though 和yet可连用。
其他部分倒装
1) so… that 句型中的so 位于句首时,需倒装。
So frightened was he that he did not dare to move an inch.
2) 在某些表示祝愿的句型中:
May you all be happy.
3) 在虚拟语气条件句中从句谓语动词有were, had, should等词,可将if 省略,把 were, had, should 移到主语之前,采取部分倒装。
Were I you, I would try it again.
典型例题:
1) Not until the early years of the 19th century___ what heat is
A. man did know B. man knew C. didn't man know D. did man know
答案为D. 否定词Not在句首,要求用部分倒装的句子结构。
2) Not until I began to work ___ how much time I had wasted.
A. didn't I realize B. did I realize C. I didn't realize D. I realize
答案为B。
3) Do you know Tom bought a new car?
I don't know, ___.
A. nor don't I care B. nor do I care
C. I don't care neither D. I don't care also
解析:答案为B. 句中的nor引出部分倒装结构,表示"也不"。由 so, neither, nor引导的倒装句,表示前一情况的重复出现。其中, so用于肯定句, 而 neither, nor 用在否定句中。
名词性从句
在句子中起名词作用的句子叫名词从句 (Noun Clauses)。 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的连接词
引导名词性从句的连接词可分为三类:
连接词:that,whether,if 不充当从句的任何成分)
连接代词:what, whatever, who, whoever, whom,
whose, which.
连接副词:when, where, how, why
不可省略的连词:
1. 介词后的连词
2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.
We heard the news that our team had won.
比较:whether与if 均为"是否"的意思。 但在下列情况下,whether 不能被if 取代:
1. whether引导主语从句并在句首
2. 引导表语从句
3. whether从句作介词宾语
4. 从句后有"or not"
Whether he will come is not clear.
大部分连接词引导的主语从句都可以置于句末,用 it充当形式主语。
It is not important who will go.
It is still unknown which team will win the match.
名词性that-从句
1)由从属连词that引导的从句叫做名词性that-从句。 That只起连接主句和从句的作用,在从句中不担任任何成分,本身也没有词义。名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语,例如:
主语:That he is still alive is sheer luck. 他还活着全靠运气。
宾语:John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。
表语:The fact is that he has not been seen recently. 事实是近来谁也没有见过他。
同位语:The fact that he has not been seen recently disturbs everyone in his office.
近来谁也没有见过他,这一事实令办公室所有的人不安。
形容词宾语:I am glad that you are satisfied with your job.
你对工作满意我感到很高兴。
2)That-从句作主语通常用it作先行词,而将that-从句置于句末,例如:
It is quite clear that the whole project is doomed to failure. 很清楚,整个计划注定要失败。
It's a pity that you should have to leave. 你非走不可真是件憾事。
用it作形式主语的that-从句有以下四种不同的搭配关系:
a. It + be +形容词+ that-从句
It is necessary that… 有必要……
It is important that… 重要的是……
It is obvious that… 很明显……
b. It + be + -ed 分词+ that-从句
It is believed that… 人们相信……
It is known to all that… 从所周知……
It has been decided that… 已决定……
c. It + be +名词+ that-从句
It is common knowledge that… ……是常识
It is a surprise that… 令人惊奇的是……
It is a fact that… 事实是……
d. It +不及物动词+ that-分句
It appears that… 似乎……
It happens that… 碰巧……
It occurred to me that… 我突然想起……
名词性wh-从句
1)由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外,还可充当介词宾语、宾语补语和间接宾语等,例如:
主语: How the book will sell depends on its author. 书销售如何取决于作者本人。
直接宾语:In one's own home one can do what one likes. 在自己家里可以随心所欲。
间接宾语:The club will give whoever wins a prize.
俱乐部将给得胜者设奖。
表语: My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。
宾语补足语:She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。
同位语: I have no idea when he will return.
我不知道他什么时候回来。
形容词宾语:I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。
介词宾语: That depends on where we shall go.
那取决于我们去哪儿。
2)Wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末,例如:
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married. 他们何时结婚依然不明。
if, whether引导的名词从句
1)yes-no型疑问从句
从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,因此也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同, 例如:
主语:Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。
宾语:Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。
表语:The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。
同位语:They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。
形容词宾语: She's doubtful whether we shall be able to come. 她怀疑我们是否能够前来。
介词宾语: I worry about whether he can pass through the crisis of his illness. 我担心他是否能度过疾病的危险期。
2)选择性疑问从句
选择性疑问从句由关联词if/whether…or或whethe…or not构成,例如:
Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。
I don't care whether you like the plan or not.我不在乎你是否喜欢该计划。本回答被提问者采纳
