13. 句子的种类
(一)按使用目的可分为陈述句、疑问句、祈使句和感叹句。

Sentences):说明一个事实或陈述一种看法。
Light travels faster than
sound. 光比声速度快。 (说明事实)

boring. 这部电影很乏味。
(说明看法)
2) 疑问句(Interrogative
Sentences):提出问题。有以下四种:
a. 一般疑问句(General Questions):

the work in time?

3) 祈使句(Imperative

4) 感叹句(Exclamatory Sentences):表示说话人惊奇、喜悦、愤怒等情绪,例如:

(二)句子按其结构可以分为以下三类:
1) 简单句(Simple
Sentences):只包含一个主谓结构句子叫简单句,例如:

她喜欢集邮。
(主) (谓)
2) 并列句(Compound
Sentences):包含两个或两个以上主谓结构的句子叫并列句,句与句之间通常用并列连词或分号来连接,例如:
The food
was good, but he had little appetite.
(主) (谓)
(主)(谓)
食物很精美,但他却没什么胃口。
3) 复合句(Complex
Sentences):包含一个主句从句和一个或几个从句的句子叫复合句,从句由从属连词引导,例如:

when we got to the cinema.
主句
从句

(三)基本句型(Basic Sentence
Patterns):英语中千变万化的句子归根结底都是由以下五种基本句型组合、扩展、变化而来的:
1)主 + 动(SV)例如:
I
work. 我工作。
2)主 + 动 + 表(SVP)例如:
John is busy. 约翰忙。
3)主 + 动 +
宾(SVO)例如:

5)主 + 动 + 间宾 + 直宾(SVOiOd)例如:

made me a new dress. 我母亲给我做了一件新衣裳。
1 祈使句结构
祈使句用以表达命令,要求,请求,劝告等。
1) 祈使句有两种类型,一种是以动词原形开头,在动词原形之前加do (但只限于省略第二人称主语的句子)。
Take this seat.
Do be careful.
否定结构:
Don't
move.
Don't be late.
2) 第二种祈使句以let开头。
Let 的反意疑问句
a. Let's
包括说话者
Let's have another try,shall we / shan't we?
= Shall we have
another try?
b. Let us 不包括说话者
Let us have another try,will you
/ won't you?
= Will you please let us have another
try?
否定结构:
Let's not talk of that matter.
Let us not talk of that
matter.
2 感叹句结构
感叹句通常有what, how引导,表示赞美、惊叹、喜
悦、等感情。
what修饰名词,how
修饰形容词,副词或动词,感叹句结构主要有以下几种:
掌握它的搭配,即掌握了感叹句的重点。
How +形容词+ a
+名词+ 陈述语序
How+形容词或副词+ 陈述语序
What
+名词+ 陈述语序
What+a+形容词+名词+ 陈述语序
What+ 形容词+复数名词+
陈述语序
What+ 形容词+不可数名词+ 陈述语序
How clever a boy he is!
How lovely
the baby is!
What noise they are making!
What a clever boy he is!
What
wonderful ideas (we have)!
What cold weather it is!
感叹句的省略形式为:
What a
clever boy (he is)!
典型例题
1)___ food you've cooked!
A. How a
nice B. What a nice C. How nice D. What nice
答案D. 由于How
修饰形容词,副词;what修饰名词。且food为不可数名词,因此A,B 排除。C How + adj. 后面不能再加名词,因此只有D正确,其句型为What +
adj. +n. (不可数)
2)___terrible weather we've been having these days!
A.
What B. What a C. How D. How a
答案A. weather为不可数名词,B,D排除。C为how + adj.
后面不应有名词。只有A,符合句型What +形容词+不可数名词。
3) --- _____ I had!
--- You really
suffered a lot.
A. What a time B. What time C. How a time D. how
time
答案A. 感叹句分两类:
1:What + n.+主谓部分
2:How + adj. / adv. /
v.+主谓部分。本题属第一种,但省略了bad,相对于 What a bad time I had! 这是个习惯用语。
3 强调句结构
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.
4 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。
5 反意疑问句
1) 陈述部分的主语是I,疑问部分要用 aren't
I.
I'm as tall as your sister,aren't I?
2) 陈述部分的谓语是wish,疑问部分要用may

nobody, never, few, seldom, hardly, rarely, little等否定含义的词时,疑问部分用肯定含义。

?
4) 含有ought to 的反意疑问句,陈述部分是肯定的,疑问部分用shouldn't / oughtn't +主语。

been to Beijing for several times, he should have been in China now, shouldn't

14. 倒装
14.1
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.
1 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.
2 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。
3 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.
4 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.
5 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.
6 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。
7 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。 |
