强调句否定句倒装句.doc

第20节 强调句、倒装句

一、强调句
1、常考的强调句结构是it 引导的句子。
　 It is (was) 被强调部分+ that (who) + 句子其他部分。
此结构强调的成分仅限于主语，宾语和状语。
　　It is from the sun that we get light and heat.
　　It was not until I had read your letter that I understood the true state of affairs.
典型例题
1） It was last night ___ I see the comet.
A.　the time　B.　when　 C.　that　　D.　which
　 答案C. 强调句的结构是： It +be +强调部分 + that (who) + 主谓句。　强调句的连词只有两个，that和who。当强调的部分是人，且为句子的主语时，才用 "who"，其余用that。
　原句：　My father did the experiment in the lab yesterday evening.
　强调主语： It was my father who did the experiment in the lab yesterday evening.
　强调宾语： It was the experiment that my father did in the lab yesterday evening.
　强调时间： It was yesterday evening that my father did the experiment in the lab. (注意不用when)
　强调地点： It was in the lab that my father did the experiment yesterday evening.
2）It is ten years ___ Miss Green returned to Canada.
A. that　B. when　 C. since　 D. as
　 答案C. 考点是连词用法。 本题易误选为A. that. 其实本句不是强调句。若是，去掉It　 be… that还应是一个完整的句子。而本句去掉 'It is…that'，只剩下ten years Miss Green returned to Canada. 不成句。因此本句不是强调句。
　 It is /was +时间+ since…　其中is<---> has been　 was <---> had been.

2、用助动词进行强调
强调句还有一种类型，就是用助动词do (did，does) 强调谓语。
　She does like this horse.　她的确喜欢这匹马。
　Please do take care of yourself. 千万保重。　

二、否定句
否定转移
1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
　 I don't think I know you.　我想我并不认识你。
　 I don' t believe he will come.　我相信他不回来。
注意：若谓语动词为hope,宾语从句中的否定词不能转移。
　 I hope you weren't ill. 我想你没有生病吧。

2) 将seem, appear 等后的从句的否定转移到前面。
　 It doesn't seem that they know where to go.
　 看来他们不知道往哪去。

It doesn't appear that we'll have a sunny day tomorrow.
　 看来我们明天不会碰上好天气。

3) 有时将动名词，介词短语或整个从句的否定转变为对谓语动词的否定。
　 I don't remember having ever seen such a man.　
　 我记得从未见过这样一个人。 (not否定动名词短语 having…)
　 It's not a place where anyone would expect to see strange characters on the street.
　 在这里，人们不会想到在街上会碰上陌生的人。
　(anyone 作主语，从句中的谓语动词不能用否定形式。)

4) 有时状语或状语从句中否定可以转移到谓语动词前。
　 The ant is not gathering this for itself alone.　(否定状语)　蚂蚁不只是为自己采食。

　 He was not ready to believe something just because Aristotle said so. (否定because状语) 他并不因亚里斯多德说过如何如何，就轻信此事。

　She had not been married many weeks when that man's younger brother saw her and was struck by her beauty.　(否定状语many weeks)　她结婚还不到几个月，这个人的弟弟就看见她了，并对她的美貌着了迷。

三、倒装句----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
