【拔高版】【中考英语重难点语法复习专题】第三讲：复合句的时态和省略（含习题+答案）

第三讲：复合句的时态和省略
专题概述：
复合句即主从复合句，由一个主句和一个 ( http: / / www.21cnjy.com )或一个以上从句构成。主句为句子主体，从句只用作句子的一个次要成分，不能独立成为一个句子。从句通常由关联词引导,并由关联词将从句和主句联系在一起。
语法考点：
1. 复合句的引导词
2. 复合句的时态
3. 复合句的省略
3.2复合句的时态
复合句时态的选择，也是中考必考题。主要出现在完形填空和语法填空。考生需要重点掌握。
一、名词性从句
◆ 宾语从句
主句和从句之间的时态的一致关系,通常由主句谓语的时态决定从句谓语的时态.
⒈若主句谓语动词是现在时或将来时,如：一般现在时,现在完成时,一般将来时,将来完成时等,从句可以根据需要使用任何时态.
He says that he is ( http: / / www.21cnjy.com )doing well in his lessons.you will miss a lot of lessons.the boy is
⒉若主句谓语动词是过去时态(一般过去时,过去进行时,过去完成时,过去将来时,过去将来完成时),从句谓语动词也必须是过去时态.
He said he e ( http: / / www.21cnjy.com )njoyed himself last Sunday.he hadn’t bought any present.the would come back the next day.he was doing his homework·
⒊当从句表示客观事物或真理, ( http: / / www.21cnjy.com )或人们已经公认的道理时,其时态不受主句谓语动词的时态的影响.即使主句谓语动词使用了过去时的某种时态,从句的时态仍然是现在的某种时态.
1)The teacher said the earth goes around the sun。
2)He said the sun rises in the east.
3)His father said he gets up at six o'clock every morning.
4)He told me the light travels faster than the sound.
⒋当从句表示并未出现或尚未实现的愿望时,必须用过去时态.
⒌（可包含在 1/2 中 ( http: / / www.21cnjy.com )）有些形容词后面可跟有从句,这种从句一般可看作宾语从句,其谓语也应与主句谓语的时态保持一致.可跟这种宾语从句的形容词有：afraid, glad, sure, confident, sorry, certain, conscious, aware等.一致的原则与宾语从句相同.
I'm confident that I'll pass the exam. 我有信心通过考试.
He was lucky that he wasn't killed. 他很幸运没有被杀死.
◆ 主语从句,表语从句和同位语从句
主句和从句之间的时态一致关系所遵守的法则和宾语从句相同.
1. It appears that som ( http: / / www.21cnjy.com )e little trouble was caused by a woman, whose name has not been ascertained.
看来这件小小的麻烦是由一个至今尚不清楚其姓名的女人所引起的.
2. It was known long ag ( http: / / www.21cnjy.com )o that Professor Einstein played a key role in the development of the theory of relativity.
人们早已知道,爱因斯坦教授对相对论的发展起了关键作用.
3. It was proved c ( http: / / www.21cnjy.com )enturies ago that the speed of light is 186,000 miles a second.
几世纪前就证实了光的速度为每秒 186,000 英里.
4. The fact that ( http: / / www.21cnjy.com ) man would soon be able to visit the moon built up new scientific interest in earth's nearest neighbor.
人类不久可以游览月球的事实,引起了对地球最近邻居的新的科学兴趣.
二、定语从句与主句的时态一致关系
定语从句的时态是根据事物真实发生的情景决定不受主句影响，因为定语从句的作用只是在修饰句子中的名词之类的,和句子本身的时态没有关系.
He is a man whose telephone was stolen. → 他是那个手机被偷的那个人.
主句一般现在时,从句过去时,因为手机真实被偷是在过去发生.
I went to the apartment in which Mary lives in. → 我去过 Mary 现在住的房子.
主句过去式,从句一般现在时,因为我去过的那个房子,Mary 确实现在在住.
⒈若定语从句的谓语表示的动作和主句谓语表示的动作同时发生,则要求使用同样的时态.
The original ( http: / / www.21cnjy.com )manuscript of "The Theory of Relativity" was written by Einstein who was then an employee in a patent office. → "相对论"的原稿是由当时在一家专利办公室工作的爱因斯坦写的.
⒉主句与定语从句的谓语表示的动作如果不是同时发生,时态则不要求一致.
1．Have you seen the new golf clubs that Mr. Stevens gave Bill
你看过史蒂文斯先生给比尔的那些新高尔夫球棒了吗
2．I painted several pictures that are now on show in the museums.
我画了几张画,现在正在博物馆里展出.
三、状语从句与主句的时态 →状语从句中的时态对应类型。（同名词性从句）
1、主句谓语动词为现在时态，则从句动词可根据需要使用任何时态；
Each of the major gl ( http: / / www.21cnjy.com )acial stages produces distinctive land forms that remain long after the glacier has disappeared.
每一主要冰河期都产生特殊的地形,这种地形一直保留到冰川消失之后很久.
2、主句谓语动词为过去时态，从句的时态一般是过去范畴的时态，其中有如下几种情况要注意：
1. When Lincoln ( http: / / www.21cnjy.com )became President of the USA, he was completely involved in the problem of slavery.
当林肯成为美国总统时,他便陷入到奴隶问题的 漩涡中去了.
2. The children r ( http: / / www.21cnjy.com )an away from the orchard(果园) the moment they saw the guard.
孩子们跑离果园时看到了卫兵。
3. After she ha ( http: / / www.21cnjy.com )d finished her work, she hurried to the nursery to pick up her child.
干完工作后,她匆匆赶到托儿所接孩子.
4. The director ( http: / / www.21cnjy.com ) had explained the details many times before the workers took the job.
工头在工人们开始工作前把细节给他们讲了好多遍.
3、状语从句中特殊的时态关系
【主将从现】（条件状语、时间状语和让步状语从句）
主句为一般将来时（或包含情态动词/祈使句），从句谓语动词常用一般现在时表示将来；
常见的有以下三种情况：
① 条件状语从句的主句是一般将来时，那么从句常常用一般现在时。
When I grow up, ( http: / / www.21cnjy.com ) I’ll be a nurse and look after patients. 我长大后要当一名护士，照顾病人。
② 主句是祈使句，那么从句通常要用一般 ( http: / / www.21cnjy.com )现在时。
Don’t laugh at me when I make a mistake. 我犯错误的时候不要笑话我。
③ 主句含有情态动词的一般现在时，根据需要从句多用一般现在时。
You should be quiet when you are in the reading room. 在阅览室时应保持安静。
【特定引导词及句式的时态】
◆ since
since 引导的时间状语从句为一般过去时，主句中的时态用现在完成时或现在完成进行时
Eg：
1．Jenny has had another ( http: / / www.21cnjy.com ) baby since I saw her last. 从上次我见到 Jenny 以来她又生了个孩子。
2．I have been l ( http: / / www.21cnjy.com )earning English since I was in Grade 3. 自从上三年级以来，我一直在学英语。
3．The girl told her father she had been ill since she came home.
那个女孩告诉她父亲，自从回到家她就一直在生病。
◆ before
before 引导的时间状语从句若是过去时，主句可用一般过去时或过去完成时。
Eg：
1. He closed the door, before he left the classroom. 他在离开教室之前关上了门。
2. We had been to four ( http: / / www.21cnjy.com ) cities before he came to join us. 他来加入我们之前我们已经去了四个城市了。
◆ by the time
by the time 指到某一点时 ( http: / / www.21cnjy.com )间为止，主句常用完成时态。一般情况下，如果从句表示的是过去时间，主句常用过去完成时；如果从句表示的是将来时间，主句则常用将来完成时。
Eg：
1．By the time you come here tomorrow, I will have finished this work.
你明天来这儿的时候，我将已经完成此工作了。
2．By the time he was 15, he had travelled to more than 12 countries.
到15岁为止，他已经去过12个国家了。
3．By the time he went abroad, he was 15. 他出国那年 15 岁。
◆ . no sooner. . . than…，hardly / scarcely / barely…when… ，其主句通常用过去完成时，从句通常用一般过去时。
Eg：1. Hardly had he arrived when she started complaining.他刚到她就抱怨起来。
2. No sooner had h ( http: / / www.21cnjy.com )e gone to sleep than the telephone rang. （倒装句）他刚睡着，电话铃就响了。
3. He had no soone ( http: / / www.21cnjy.com )r gone to sleep than the telephone rang. 他刚睡着电话铃就响了
四、宾语从句和状语从句同时出现。
①I don't know if he ( http: / / www.21cnjy.com )will come. If he comes, I will tell him about the accident.
②I don't know when ( http: / / www.21cnjy.com )he will come tomorrow. When he comes, I will tell him about the accident.
五、as when while 的区别和用法
1. 当从句中的谓语动词是持续性的动作， ( http: / / www.21cnjy.com )主句是短暂性动词可以用while, when或as。
→ While / When / As I was walking down the street, I noticed a police car in front of the bank.
2. 当从句中的谓语动词表示瞬间动作时,不可 ( http: / / www.21cnjy.com )用while。
→ He was on the point of leaving when someone knocked at the door.
3. 如果谈论两个长动作,最常用 ( http: / / www.21cnjy.com )的是while。
→ While John was biting his nails, I was working out a plan to get us home.
注意：
1、若主句与从句 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )表示的是两个同时发生的短暂性动作，含有类似汉语"一……就""刚要---就"的意思，英语一般要用as (也可用when)。如：
The ice cracked as [when] I stepped onto it. 我一踩冰就裂了。
He is about to go out when it rains. 他刚要出门就下起了雨
2.若要表示主句动作伴随从句 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )动作同时发展变化，有类似汉语"随着"的意思，英语习惯 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank ) 上要用as，而不用when或while。如：
The room grew colder as the fire burnt down.
As time goes by my memory seems to get worse.
注：若不是引导从句 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )，而是引出一个短语，则用with，不用as。如：
With winter coming on, it’s time to buy warm clothes.
3. 若暗示一种规律性，表示"每当……的时候"，英语一般要用when。如：
It’s cold when it snows.
He smiles when you praise him.
4、若主句与从句 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )所表示的动作不是同时发生，而是有先后顺序时，一般要用when。如：
When he arrives he’ll tell us all about the match.
When she had finished she waited as though for a reply.
5、若从句 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )所表示的"当……的时候"具有"趁机"的意味，则通常用while。如：
Strike while the iron is hot. 趁热打铁。
3.3复合句的省略
状语从句的省略
状语从句同时具备下列两个条件:
①主句和从句的主语一致，或从句主语为it；
②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。
When ( the mus ( http: / / www.21cnjy.com )eum is ) completed , the museum will be open to the public next year .
He’ll go to the seaside for his holiday if (it is ) possible. 　　
另外，比较状语从句经常省略
I'm taller than he (is tall ).
The higher the temperature (is), the greater the pressure (is ).
状语从句的"简化"现象常存在于以下五种状语从句中:
①由if, unless等引导的条件状语从句;
②由although, though, even if / though等引导的让步状语从句;
③由when, while, as, before, after, until / till等引导的时间状语从句;
④由as, as if, as though等引导的方式状语从句;
⑤由as, than等引导的比较状语从句。
(1)当状语从句的主语是it，且谓语动词是be时，it和be要完全简化掉。
If (it is) possible, he will help you out of the difficulty.
如果可能的话,他会帮你摆脱困境。
You must attend the meeting unless (it is) inconvenient to you.
除非情况对你来说不方便,否则你必须出席这次会议。
Unless (it is) necessary ,you'd better not refer to the dictionary.
如果没有必要，你最好不要查字典。
(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形:
◆ 连词+形容词
As (he was) young, he learned how to ride a bike. 他小时候就学会了骑自行车。
Whenever (she is) free, she often goes shopping. 她有空就去逛商店。
Work hard when (you are) young, or you'll regret. 少壮不努力,老大徒伤悲。
◆ 连词+名词
While (he was) a young ( http: / / www.21cnjy.com ) boy, he was always ready to help others. 他在孩提时代就乐于助人。
Although (he was) ( http: / / www.21cnjy.com )a farmer, now he is a famous director. 尽管他曾是个农民,而现在是位著名的导演了。
◆ 连词+现在分词 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )
As (she was) wa ( http: / / www.21cnjy.com )lking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲。
Although (he is) doin ( http: / / www.21cnjy.com )g his best in maths these days, he has still got no good marks.

◆ 连词+介词短语
He looked every ( http: / / www.21cnjy.com )where as if (he was) in search of something . 他到处看似乎在找什么东西。
注意：当从句主语和主句主语不一致时，从句部分要么用完全形式,要么用独立主格结构 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )来表达。
When the meeting was ( http: / / www.21cnjy.com ) over, all the people went out of the meeting-room.
当会议结束时,人们都走出了会议室。
(=The meeting over,all the people went out of the meeting-room）

定语从句的省略（非限制性定语从句中）
1. 语定从句转换成不定式"to do" ( http: / / www.21cnjy.com )
定语从句的谓语动词是将来时或含有情态动词或含有序数词the next， the last等时，该定语从句转换为不定式"to do".
eg: The plane w ( http: / / www.21cnjy.com )hich will arrive is from Hubei.→The plane to arrive is from Hubei。

"介词+关系代词"引导的定语从句和"介词+ ( http: / / www.21cnjy.com )关系代词或副词+不定式"充当的定语，可以和不定式进行转换。被这种定语修饰的名词往往在逻辑上充当不定式动作的地点、时间或工具。例：
eg: She wanted a room in which she could do her homework.
→She wanted a room in ( http: / / www.21cnjy.com ) which to do her homework.
eg: She had only a pen with which she can write.
→She had only a p ( http: / / www.21cnjy.com )en to write with.或She had only a pen with which to write.
3. 定语从句可以转换为现在 ( http: / / www.21cnjy.com )分词（短语）
如果定语从句的谓语是主动语态，且发生的时间与主句的谓语所表示的动作所发生的时间同时，此时可以将定语从句转换成现在分词短语）。
eg: Have you ever talked to the girl who is dancing to music over there？
→Have you ever talked to the girl dancing to music over there？　
4. 定语从句可以转化为过去分词（短语）
如 ( http: / / www.21cnjy.com )定语从句的谓语是被动语态，或是"系动词+过去分词（表语）"结构，且从句的谓语动词所表示的动作或状态是在主句的谓语之前发生。此时，我们可以将定语从句转换成过去分词（短语）。
eg: The report that was made yesterday will be discussed today.
→The report made yest ( http: / / www.21cnjy.com )erday will be discussed today.
eg: The dictionary which my mother bought for me is very useful.
→The dictionary bought for me by my mother is very useful.
注意：虽关系代词作定语从句的主语，但如从句的谓语中含有情态动词，则不能转换成分词（短语）。
Those who mus ( http: / / www.21cnjy.com )t hand in their homework before 12 are studying hard now.
此句不能转成：Those handing ( http: / / www.21cnjy.com ) in their homework before 12 are studying hard now.
动词不定式做后置定语的其他情况：
被修饰的词是形容词最高级或者被形容词最 ( http: / / www.21cnjy.com )高级修饰； → He is the fastest runner to arrive at the destination.
不定代词something、nothing等后常用不定式做定语； → I have something to tell you.
time, way, reason, c ( http: / / www.21cnjy.com )hance, ability, courage, opportunity, wish等用不定式作后置定语；
→ He is born with the ability to dance and sing.
宾语从句的省略
① 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
Li Ming hopes he ( http: / / www.21cnjy.com )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.
② 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

注：当主句谓语动词是tell,a ( http: / / www.21cnjy.com )sk,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
Could you tell me ( http: / / www.21cnjy.com )how I can get to the station？ →Could you tell me how to get to the station？
　　
③ 主句的谓语动词是order,require等时，如果主句和从句的主语不一致

④ 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。

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.

⑥ 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 t ( http: / / www.21cnjy.com )hat 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，
I found that it was d ( http: / / www.21cnjy.com )ifficult to learn English well. →I found it difficult to learn English well.

→Soon we found the ground covered with thick snow.
