高三英语语法知识点1
定语从句 掌握定语从句的关键：弄清关系词在定语从句中的语法功能
1. When, why, where 为关系副词，在定语从句中状语。
2.Who, who, that, which为关系代词，在定语从句中作主语、宾语、表语。
1)We’ll never forget the date _________ the People’s Republic of China was founded.
2)October 1st 1949 is the date___________ we’ll never forget.
3)Did he tell you the reason _________ he didn’t come to your birthday party?
4)Now we understand the reason _________ he tried to explain to us last time.
5)This is the room __________ Chairman Mao once lived.
1)This is the museum ____________ we paid a visit to ten years ago.
The keys:1) when 2) which/that 3) why 4) that/which 5) where 6) which/that
名词性从句
1 考查it作形式宾语的句型
I hate _________ when people talk with their mouths full. A. it B. that C. these D. them
( A .it代替后面的由when引起的宾语从句)
2名词性从句和让步状语从句的区别
Sarah hopes to become a friend of _________ shares her interests.
A. anyone B. whomever C. whoever D no matter who
(Key: C. “whoever shares her interests” 作 of 的宾语从句，Whomever不作主语，而no matter who 只引导让步状语从句。)
1) Eat _______ cake you like and leave the others for ________ comes in late.
A. any; who B. every; whoever C. whichever; whoever D. either; whoever
2) He won’t be accepted _____________ he works. (不管有多努力)
( 1).C 2) no matter how/however )
3 what, that 在名词性从句中的区别：that在名词性从句中不作成分， 而what 作成分。
1)A modern city has been set up in _________ was a wasteland ten years ago.
2)_____________fashion differs from country to country may reflect the cultural differences form one aspect.
key: 1) what. what was a wasteland ten years ago作 in 的宾语从句, what作从句的主语;
2) That. 句中”fashion differs from country to country”已独立成句，不再需要其他句子成分，故用That。
1)After _________ seemed half an hour, the teacher gave us the correct answer.
2)_______ we can’t get seems better than ________ we have.
3)The other day, my brother drove his car down the street at _______ I thought was a dangerous speed. (以上几个空格都填what)
4 考查 what, which, who(m),whose与whatever, whichever , who(m)ever, whosever两类连接代词的区别。
1)---Are you still thinking about yesterday’s game?
---Oh, that’s__________.
A. what makes me feel excited B. whatever I feel excited about
C. how I feel about it D. when I feel excited
3) It was a matter of _________ would take the position.
A. who B. whoever C. whom D. whomever
1)题中谈论的“昨天的比赛”是“一件事情”，而非“无论何事(whatever)”,因此正确答案为 what相当于the thing that。
2)本题表达的含义为：这是一个由谁担当此任的问题, 指代一件事情。句中介词of后的从句仍然具有疑问意义，由此可排除B,D;又因从句缺少主语，故A 为正确答案); 又如:
___________has helped to save the drowning girl is worth praising. (不管是谁，任何……的人)
(填Whoever/Anyone who ,所填部分指人. )
高三英语语法知识点2
The number of smokers，__as__is reported，has dropped by 17 percent in just one year.
解析：此句为as引导的非限制性定语从句。as意为“正如，正像”，在定语从句中可作主语、宾语或表语;as在这里代替整个主句的内容;“as is reported”意为“正如被报道的那样”。句意：正如被报道的那样，烟民的数量在仅仅一年的时间就下降了17%。
Some passers-by witnessed the car accident __where__ five passengers were killed, a baby included.
解析：句意为：一些路人目睹了这场事故，其中有五位乘客丧生包括一个婴儿。设空处引导定语从句，且关系词在从句中作地点状语，故用where引导。
Spit-take” refers to an act __where__ someone spits liquid out of his or her mouth when he or she hears something funny or surprising.
解析：句意为：“笑喷”是指一种行为：某人在听到有趣的或吃惊的事情后从嘴中喷出液体。设空处引导定语从句修饰act，引导词在从句中作地点状语，因此用where引导。
Cultural shock is a feeling __which/that__most travelers experience in a foreign country __where__ they find the culture is quite different from that of their own.
解析：句意为：文化冲击是一种大多数游客在外国会经历的感觉，在那里他们会感觉外国的文化和自己的(文化)有很大的不同。分析句子成分可知，两空均引导定语从句，第一空的先行词为a feeling，且在从句中作experience的宾语，因此用which/that引导;第二空的先行词为a foreign country，在从句中作地点状语，故用where引导。
Tibet is such a place __as__ all the people across the world are dreaming of visiting.
解析：句意为：西藏是一个全世界所有的人都梦想游览的地方。定语从句的先行词为a place，其前有such修饰，引导词应用关系代词as。

反意疑问句中的易错点
1.在一般疑问句中，无论肯定的问或是否定的问，如果回答为肯定则用yes，反之则用no.特别注意如果出现省略则看下文所暗示的意义。
①—Are you a new comer?
—Yes, I came here only yesterday.
②—Isn’t Tom a good student?
—Yes, he is excellent.
③—Don’t you think the composition good?
—No, It can’t be any worse.
注意：在②③句中，当回答的意思与问句相一致时，则用No，译为“是的”，当回答的意思与问句相反时，则用Yes，译为“不”
2.情态动词must
① I must leave now, mustn’t I ?
② He must be in the classroom, isn’t ?(表推测)
③ He must have finished his homework, hasn’t he ? (表现在的结果)
④ He must have finished his homework yesterday afternoon,didn’t he? (表过去)
当句子中有表示猜测的情态动词时，其反意疑问句的构成不能再用原句中的情态动词，而应根据原句在去掉情态动词的情况下的主谓关系来确定其反问形式。

特殊疑问词引导的从句
1、主语从句：特殊疑问词引导主语从句时，常用it作形式主语。
2、宾语从句
(1)常见的能接特殊疑问词引导的宾语从句的动词有see, tell, ask, answer, know, decide, find out, imagine, suggest, doubt, wonder, show, discuss, understand, inform, advise等。
(2)作介词宾语。
3、同位语从句、表语从句
名词性关系从句
What=the thing(s) which/that, whoever=anyone who, whichever=anyone/anything that, whatever=anything that, where=the place where, when=the time when
名词性从句的几个难点
(一)that不可省略的情况
1、主语从句，that从句置于句首时;
2、当一个句子有两个或多个并列的宾语从句时，引导第二和以后几个从句的that不可省略;
3、由it作形式宾语时，that引导的宾语从句中，that不可以省略。
(二)wh-ever与no matter wh-的用法区别
Wh-ever既可引导名词性从句，又可引导让步状语从句;而no matter wh-只能引导让步状语从句。
(三)as if/though, because, why可以引导表语从句
注意：because引导的表语从句，主语不能是reason或cause,而且since,as不能引导表语从句。
(四)that引导的同位语从句与关系代词that引导的定语从句的区别
That引导的同位语从句成分是完整的，that在从句中不担当任何成分;that引导的定语从句成分是残缺的，that在从句中充当主语、宾语或表语。

1.Have__a__good time!
解析：考查冠词。have a good time玩得开心。
2.Life is like __an__ ocean: Only __the__ strong-willed can reach the other shore.
解析：第一个空表示泛指，且ocean以元音音素开头，故用不定冠词an;形容词前用定冠词表示一类人，the strong-willed意为“意志坚强的人”。
3.I can't tell you __the__ way to the Wilson's because we don't have __a__ Wilson here in the village.
解析：way后有介词短语作定语，表特指，所以第一空填定冠词the;泛指“一个名叫Wilson的人”，第二空填不定冠词a。
4.__The__ village where I was born has grown into __a__ town.
解析：village后有定语从句修饰，是特指，故第一空填定冠词;泛指“一座城镇”，故第二空填不定冠词a。
5.Every time there was__an__outbreak，a great number of terrified people died.
解析：there was+可数名词单数，且“outbreak”以元音音素开头，故用an。
6.__The__ news of the mayor's coming to our school for a visit was given out on the radio yesterday.
解析：句意为：市长来我们学校参观的新闻昨天通过收音机发布了。名词news后有介词短语修饰，起限定作用，表特指，故填the。
