高中英语写作单句

⑸ 高中英语简单句详细讲解

（一）句子种类两种分类法w.w.w.k.s.5.u.c.o.m
1、按句子的用途可分四种：
1）陈述句（肯定、否定）：He is six years old; She didn’t hear of you before.
2）疑问句（一般、特殊、选择、反意）：Do they like skating? How old is he? Is he six or seven years old? Mary can swim, can’t she?
3）祈使句：Be careful, boys; Don’t talk in class
4）感叹句：How clever the boy is!
2、按句子的结构可分三种：
1）简单句：只有一个主语（或并列主语）和一个谓语（或并列谓语）。
e. g. He often reads English in the morning.
Tom and Mike are American boys.
She likes drawing and often draws pictures for the wall newspapers.
2) 并列句：由并列连词（and, but, or等）或分号（；）把两个或两个以上的简单句连在一起构成。
e. g. You help him and he helps you.
The future is bright; the road is tortuous. 前途是光明的，道路是曲折的。
3）复合句：含有一个或一个以上从句的句子。复合句包含：名词性从句（主语从句、宾语从句、表语从句和同位语从句）、定语从句和状语从句等。
e. g. The foreign visitors took a lot of pictures when they were at the Great Wall.

（二）简单句的五种基本句型
1、主语+系动词+表语：e. g. He is a student.
2、主语+不及物动词：e. g. We work.
3、主语+及物动词+宾语：e. g. Henry bought a dictionary.
4、主语+及物动词+双宾语（间接宾语+直接宾语）：e. g. My father bought me a car.
5、主语+及物动词+复合宾语（宾语+宾补）：e. g. Tom made the baby laugh.
注：其他各种句子都可由这一种基本句型扩展、变化或省略而构成。

主语——动词——表语：w.w.w.k.s.5.u.c.o.m
在这一句型中，动词是系动词，划线部分为表语。
1. Mr. Brown is an engineer. (名词作表语)
2. Graaly he became silent. (形容词作表语)
3. She remained standing for a hour. (现在分词作表语)
4. The question remained unsolved. (过去分词作表语)
5. The machine is out of order. (介词短语作表语)
6. The television was on. (副词作表语)
7. His plan is to keep the affair secret. (动词不定式作表语)
8. My job is repairing cars. (动名词作表语)
9. The question is what you want to do. (从句作表语，即：表语从句)
注意：在下面的句子中，形容词作表语，在表语的后面常常接不定式结构。
I’m happy to meet you.
They are willing to help.
We are determined to follow his example.

主语——动词：
在这一句型中，动词为不及物动词及不及物的动词词组。在有的句子中，不及物动词可以有状语修饰。
1. The sun is rising.
2. I’ll try.
3. Did you sleep well？(well做状语，修饰不及物动词sleep)
4. The engine broke down.
注意：在此句型中，有少数不及物动词表达被动含义，表达主语本身所具有的特性，不用被动语态。
1. The book sells well.
2. The window won’t shut.
3. The pen writes smoothly.
4. Cheese cuts easily.

主语——动词——宾语：w.w.w.k.s.5.u.c.o.m
在此句型中，动词为及物动词，划线部分为宾语。
1. Do you know these people (them)？(名词或代词作宾语)
2. I can’t express myself in English. (反身代词作宾语)
3. He smiled a strange smile. (同源宾语)
4. We can’t afford to pay such a price. (不定式作宾语)
5. Would you mind waiting a few minutes？(动名词作宾语)
6. I hope that I have said nothing to pain you. (从句作宾语，即：宾语从句)
注意：并不是所有的及物动词都可以接上述各种情况作宾语，不同的动词有不同的用法，所以，在学习动词时，一定要掌握其用法。

主语——动词——宾语——宾语：
在此句型中，动词可以称作双宾语动词，在英语中，这样的动词并不多，在学习中遇到时，要牢记。后面的宾语为间接宾语和直接宾语，其中，间接宾语在前，一般表人，直接宾语在后，一般表物。这类句型有三种情况。
第一种情况，间接宾语可以改为由to引导的短语。
1. He handed me a letter.
He handed a letter to me.
2. She gave me her telephone number.
She gave her telephone number to me.
第二种情况，间接宾语可以改为由for引导的短语。
3. She sang us a folk song.
She sang a folk for us.
4. She cooked us a delicious meal.
She cooked a delicious meal for us.
第三种情况，直接宾语可以由宾语从句充当。
5. Tell him I’m out.
6. Can you inform me where Miss Green lives？

主语——动词——宾语——宾语补足语：
在此句型中的动词，叫做可以跟复合宾语的动词，在英语中，这样的动词也不多。后面的宾语补足语是说明宾语的情况的，宾语和宾语补足语一起被称作复合宾语。这个句式是英语中比较复杂的一个句式，因为复合宾语的构成内容较多。下面句子中划线部分为宾语补足语。w.w.w.k.s.5.u.c.o.m
1. He found his new job boring. (形容词作宾补)
2. The called their daughter Mary. (名词作宾补)
3. This placed her in a very difficult position. (介词短语作宾补)
4. We went to here house but found her out. (副词作宾补)
5. What do you advise me to do？(不定式作宾补)
6. We thought him to be an honest man. (tobe作宾补)
7. He believed them to have discussed the problem. (不定式的完成式作宾补)
8. He believed her to be telling the truth. (不定式的进行式作宾补)
9. Did you notice him come in？(不带to的不定式作宾补)
10. I saw her chatting with Nancy. (现在分词作宾补)
11. He watched the piano carried upstairs. (过去分词作宾补)
注意：在这个结构中，可以出现用it作形式上的宾语，把真正的宾语放在宾语补足语的后面。在此结构中，宾语常常是动词不定式或宾语从句。
1. He felt it his ty to mention this to her.
分析：it是形式宾语，his ty是宾语补足语，to mention this to her是真正的宾语。
2. I think it best that you should stay with us.
分析：it是形式宾语，best是宾语补足语，that you should stay with us是真正的宾语。
3. there be句型是一种特殊的句子，真正的主语在后面，含义为“有……”
①谓语动词和主语保持一致：There is a television in the sitting room.
②有两个或更多的主语时，动词一般和最近的一个保持一致：There are two girls and a boy dancing in the hall.
③主语的后面有时有修饰语：There are a lot of difficulties facing us. There were many things to be done(此处也可以使用to do).
④谓语动词be可以有时态的变化:There will be a concert in the park tonight. There was little change in him.
⑤谓语也可以有不定式构成的复合谓语。w.w.w.k.s.5.u.c.o.m
There used to be a cinema here.
There seems to be something the matter with her.
Is there going to be any activity tonight？
⑥there be句式变疑问句，把be提前；变反意疑问句也要借助there。
Is there any hope of getting the job？
There is nothing wrong with your watch，is there？
⑦there be句型中也可以使用诸如：live，follow，come，stand，sit，exist等不及物动词：
Once upon a time，there lived a fisherman on the island.
There came a knock at the door.
At the top of the hill there stands an old temple.
⑧用于非谓语的情况下，有时用不定式的复合结构there to be或动名词的复合结构和独立主格结构there being：
You wouldn’t want there to be another war. (不定式的复合结构)
The teacher was satisfied with there being no mistakes in his homework. (动名词的复合结构)
There being nothing else to do，we went home. (独立主格结构)

⑻ 高中英语简单句的写作，有哪五种基本句型

英语中的五种基本句型结构
一、句型1： Subject (主语) ＋ Verb (谓语)
这种句型中的动词大多是不及物动词，所谓不及物动词，就是这种动词后不可以直接接宾语。常见的动词如：work, sing, swim, fish, jump, arrive, come, die, disappear, cry, happen等。如：
1) Li Ming works very hard.李明学习很努力。
2) The accident happened yesterday afternoon.事故是昨天下午发生的。
3）Spring is coming.
4) We have lived in the city for ten years.
二、句型2：Subject (主语) ＋ Link. V(系动词) ＋ Predicate(表语)
这种句型主要用来表示主语的特点、身份等。其系动词一般可分为下列两类：
(1)表示状态。这样的词有：be, look, seem, smell, taste, sound, keep等。如：
1) This kind of food tastes delicious.这种食物吃起来很可口。
2) He looked worried just now.刚才他看上去有些焦急。
(2)表示变化。这类系动词有：become, turn, get, grow, go等。如：
1) Spring comes. It is getting warmer and warmer.春天到了，天气变得越来越暖和。
2) The tree has grown much taller than before.这棵树比以前长得高多了。
三、句型3：Subject(主语) ＋ Verb (谓语) ＋ Object (宾语)
这种句型中的动词一般为及物动词, 所谓及物动词，就是这种动词后可以直接接宾语，其宾语通常由名词、代词、动词不定式、动名词或从句等来充当。例：
1) He took his bag and left.（名词） 他拿着书包离开了。
2) Li Lei always helps me when I have difficulties. (代词)当我遇到困难时，李雷总能给我帮助。
3) She plans to travel in the coming May Day.（不定式）她打算在即将到来的“五一”外出旅游。
4) I don’t know what I should do next. (从句)我不知道下一步该干什么。
注意：英语中的许多动词既是及物动词，又是不及物动词。
四、句型4： Subject(主语)＋Verb(谓语)＋ Indirect object(间接宾语)＋Direct object (直接宾语)
这种句型中，直接宾语为主要宾语，表示动作是对谁做的或为谁做的，在句中不可或缺，常常由表示“物”的名词来充当；间接宾语也被称之为第二宾语，去掉之后，对整个句子的影响不大，多由指“人”的名词或代词承担。引导这类双宾语的常见动词有：buy, pass, lend, give, tell, teach, show, bring, send等。如：
1) Her father bought her a dictionary as a birthday present.她爸爸给她买了一本词典作为生日礼物。
2）The old man always tells the children stories about the heroes in the Long March.
老人经常给孩子们讲述长征途中那些英雄的故事。 上述句子还可以表达为：
1）Her father bought a dictionary for her as a birthday present.
2）The old man always tells stories about the heroes to the children in the Long March.
五、句型5： Subject(主语)＋Verb (动词)＋Object (宾语)＋Complement(补语)
这种句型中的“宾语 ＋ 补语”统称为“复合宾语”。宾语补足语的主要作用或者是补充、说明宾语的特点、身份等；或者表示让宾语去完成的动作等。担任补语的常常是名词、形容词、副词、介词短语、分词、动词不定式等。如：
1）You should keep the room clean and tidy. 你应该让屋子保持干净整洁。（形容词）
2) We made him our monitor.(名词)我们选他当班长。
3) His father told him not to play in the street.(不定式)他父亲告诉他不要在街上玩。
4）My father likes to watch the boys playing basketball.(现在分词)
5) Yesterday I had a picture taken with two Americans.(过去分词)
● 常见的动词有: tell, ask, advise, help, want, would like, order, force, allow等。
● 注意：动词have, make, let, see, hear, notice, feel, watch等后面所接的动词不定式作宾补时，不带to。如：
1) The boss made him do the work all day.老板让他整天做那项工作。
2) I heard her sing in the next room all the time last night.昨天晚上我听见她在隔壁唱了一个晚上。

独立主格结构
一） 独立主格结构的构成：
名词(代词)+现在分词、过去分词；
名词(代词)+形容词；
名词(代词)+副词；
名词(代词)+不定式；
名词(代词) +介词短语构成。

二） 独立主格结构的特点：
1）独立主格结构的逻辑主语与句子的主语不同，它独立存在。
2）名词或代词与后面的分词，形容词，副词，不定 式，介词等是主谓关系。
3）独立主格结构一般有逗号与主句分开。
举例：
The test finished, we began our holiday.
= When the test was finished, we began our holiday.
考试结束了，我们开始放假。
The president assassinated, the whole country was in deep sorrow.
= After the president was assassinated, the whole country was in deep sorrow.
总统被谋杀了，举国上下沉浸在悲哀之中。
Weather permitting, we are going to visit you tomorrow.
如果天气允许，我们明天去看你。
This done, we went home.
工作完成后，我们才回家。
The meeting gone over, everyone tired to go home earlier.
会议结束后，每个人都想早点回家。
He came into the room, his ears red with cold.
他回到了房子里，耳朵冻坏了。
He came out of the library, a large book under his arm.
他夹着本厚书，走出了图书馆。

三） With的复合结构作独立主格
表伴随时，既可用分词的独立结构，也可用with的复合结构。
with +名词(代词)+现在分词/过去分词/形容词/副词/不定式/介词短语
举例: He stood there, his hand raised.
= He stood there, with his hand raise.
典型例题
The murder was brought in, with his hands ___ behind his back。
A. being tied B. having tiedC. to be tiedD. tied
答案D. with +名词（代词）+分词+介词短语结构。当分词表示伴随状况时，其主语常常用with来引导。由于本句中名词"手"与分词"绑"是被动关系，因此用过去分词，选D.
注意:
1) 独立主格结构使用介词的问题：
当介词是in时，其前后的两个名词均不加任何成分（如物主代词或冠词），也不用复数。但 with 的复合结构不受此限制
A robber burst into the room, knife in hand.
( hand前不能加his)。
2) 当表人体部位的词做逻辑主语时，及物动词用现在分 词，不及物动词用过去分词。
He lay there, his teeth set, his hand clenched, his eyes looking straight up.
典型例题：
Weather___, we'll go out for a walk.
A permitted B permitting C permits D for permitting
答案B. 本题中没有连词，它不是复合句，也不是并列句。 句中使用了逗号，且we 小写，可知其不是两个简单句。能够这样使用的只有独立主格或with的复合结构。据此判断，本句中使用的是独立结构，其结构为：名词+分词。 由于permit在这里翻译为'天气允许'，表主动，应用现在分词，故选B。
如果不会判断独立结构作状语的形式，不妨将句子改为条件句，例如本句改为If weather permits, we'll go out for a walk. 然后将if 去掉，再将谓语动词改为非谓语动词即可。

不能“以貌取意”的常见句型例析

1．This is the last thing I would ever want to do．
这是我最不愿做的一件事情。
【析】“the last ＋to do；the last ＋定语从句”中的last的意思为“least willing/likely”，译为“最不愿意；最不可能”。
He's the last man I want to see．他是我最不想见的人。
He is the last person to tell a lie．他是最不可能撒谎的人。
She's the last woman I want to sit next to at dinner．她是我在宴会上最不愿与之挨着坐的女人。
2．One can't be too honest．
人越老实越好。
【析】句中“cannot．．．too．．．”意为“无论怎样……也不过分”或“越……越好”。该句型中的not可以换成 hardly，never或scarcely；too可以换成 over或enough等，意思不变。
You cannot be too careful．You cannot be over careful．＝You cannot be careful enough．你越仔细越好。
A man can never have too many friends．朋友越多越好。
3．It's a wise man that never makes mistakes．
无论多么聪明的人，也难免犯错误。
【析】“It is a ＋形容词＋名词＋that．．．”结构是一个特殊的习惯用法，意思是“无论怎样的……也不……”。真正的句子意思与字面意思相反，它具有含蓄的让步意味，切不可望文生义、译成强调句型。
It's a long lane that has no turning．无论怎样长的巷子也有转弯处。（引申意义为：耐心等待终会时来运转。）
It's a good horse that never stumbles．再好的马也有失前蹄的时候。（引申意义为：金无足赤，人无完人。）
4I'm too anxious to know the result．
我极想知道结果。
【析】英语中“too．．．to．．．”结构表示“太……以致不”的意思。例如：The star is too small to see．但是，如果too后形容词表示主语的状态、心理活动、情感态度（常见的有glad，easy，ready，anxious，eager， willing，happy等），并与其后的不定式构成固定搭配，这时too含有肯定意义，表示“very，extremely”的意思。
They are too anxious to leave．他们急于离去。
Mr．Smith was too eager to see her．史密斯先生极想见到她。
5．It's three years since he was a teacher．
他不当教师已经三年了。
【析】在“It is some time since ＋主语＋谓语＋其它成分。”这一结构中，如果从句谓语动词是非延续性动词，那么时间的计算就从该动作的发生开始算起。
It‘s three years since he joined the army．他参军已经三年了。
如果从句谓语动词是延续性动词，时间就要从该动作的结束算起。
It's many years since they lived here．他们不在这儿住已经好多年了。
6．All that glitters is not gold．
闪光的东西不一定都是金子。
【析】在句中当不定代词all，both，every及 every的复合词，副词always，often，entirely与 not一起使用时，表示部分否定，意思是“并非都是”，“不是每个人都”等。
I don't remember all these formulas．这些公式我并非全都记得。
Every man cannot do it．并非每个人都能做这个。
I don't entirely agree with you．我并不完全同意你的看法。
注意：当all，both，every等词和带im-，in-，un-，dis-等表示否定意义的前缀的词连用时，表示全部否定的意义。
All your answers are incorrect．你所有的答案都不正确。
表示全部否定时，我们常使用no，not，nobody，nothing，never，nowhere，neither等词。
None of the teachers smoke．这些老师都不抽烟。
7．The mountain is not valuable because it is high．
山并不因为高而具有价值。（山不在高）
【析】含有原因状语从句的主从复合句，形式上虽然否定主句的谓语，然而意义上则是否定该原因状语，译为“并不因为……而……”。
You cannot walk away just because someone tells you he doesn't want to buy．你不能仅仅因为他告诉你不买就走开。
Galileo was not ready to accept it just because Aristotle had said so．伽利略并不只是因为亚里斯多德说过某事如何如何，就轻易相信它。
8．I didn't pretend to understand what he said．
我假装没懂他说的话。
【析】常用动词pretend，happen的否定形式有两种：既可以否定pretend，也可以否定其后的不定式，其意义不变。
I didn't happen to be there．＝I happened not to be there．我恰巧不在那儿。
They didn't pretend to see me when I went by．＝They pretended not to see me when I went by．当我经过的时候，他们假装没有看见我。
9Let's have a rest under the big tree． It's nice and cool here．
让我们在大树下歇会吧。这儿很凉快。
【析】nice and，good and都表示“很，非常，完全”的意思。and前的形容词实质上起副词作用，修饰后边的形容词，表示强调。
I am good and ready．我都准备好了。
It is good and cold in the morning．早上非常冷。

独立主格结构
一） 独立主格结构的构成：
名词(代词)+现在分词、过去分词；
名词(代词)+形容词；
名词(代词)+副词；
名词(代词)+不定式；
名词(代词) +介词短语构成。

二） 独立主格结构的特点：
1）独立主格结构的逻辑主语与句子的主语不同，它独立存在。
2）名词或代词与后面的分词，形容词，副词，不定 式，介词等是主谓关系。
3）独立主格结构一般有逗号与主句分开。
举例：
The test finished, we began our holiday.
= When the test was finished, we began our holiday.
考试结束了，我们开始放假。
The president assassinated, the whole country was in deep sorrow.
= After the president was assassinated, the whole country was in deep sorrow.
总统被谋杀了，举国上下沉浸在悲哀之中。
Weather permitting, we are going to visit you tomorrow.
如果天气允许，我们明天去看你。
This done, we went home.
工作完成后，我们才回家。

会议结束后，每个人都想早点回家。
He came into the room, his ears red with cold.
他回到了房子里，耳朵冻坏了。
He came out of the library, a large book under his arm.
他夹着本厚书，走出了图书馆。

三） With的复合结构作独立主格
表伴随时，既可用分词的独立结构，也可用with的复合结构。
with +名词(代词)+现在分词/过去分词/形容词/副词/不定式/介词短语
举例: He stood there, his hand raised.
= He stood there, with his hand raise.
典型例题
The murder was brought in, with his hands ___ behind his back。
A. being tied B. having tiedC. to be tiedD. tied
答案D. with +名词（代词）+分词+介词短语结构。当分词表示伴随状况时，其主语常常用with来引导。由于本句中名词"手"与分词"绑"是被动关系，因此用过去分词，选D.
注意:
1) 独立主格结构使用介词的问题：
当介词是in时，其前后的两个名词均不加任何成分（如物主代词或冠词），也不用复数。但 with 的复合结构不受此限制
A robber burst into the room, knife in hand.
( hand前不能加his)。
2) 当表人体部位的词做逻辑主语时，及物动词用现在分 词，不及物动词用过去分词。
He lay there, his teeth set, his hand clenched, his eyes looking straight up.
典型例题：
Weather___, we'll go out for a walk.
A permitted B permitting C permits D for permitting
答案B. 本题中没有连词，它不是复合句，也不是并列句。 句中使用了逗号，且we 小写，可知其不是两个简单句。能够这样使用的只有独立主格或with的复合结构。据此判断，本句中使用的是独立结构， 其结构为：名词+分词。 由于permit在这里翻译为'天气允许'，表主动，应用现在分词，故选B。
如果不会判断独立结构作状语的形式，不妨将句子改为条件句，例如本句改为If weather permits, we'll go out for a walk. 然后将if 去掉，再将谓语动词改为非谓语动词即可。

9Let's have a rest under the big tree． It's nice and cool here．
让我们在大树下歇会吧。这儿很凉快。

I am good and ready．我都准备好了。
It is good and cold in the morning．早上非常冷。
