1、高中英语重点语法知识点归纳1.状语从句的省略： While walking the dog, you were careless and it got loose and was hit by a car.=While you were walking the dog当when, while, unless, as if, though, although等引导从句，若从句主语与主句主语一致或从句主语为it，且从句谓语中含有be动词时，可以省略从句中的主语和be动词，构成省略句句型。上面所列举的连接词后如果接分词形式，与主句主语是主动关系，要用现在分词doing，与主句主语是被动关系，要用过去

2、分词done。(1)Children, when _(accompany)by their parents, are allowed to enter the stadium.(2)When _(necessary), you can look up the word in a dictionary(3)Although _(grow)well, the plant still needs watering every other day.2.英语中的“强调”：句子成分有主、谓、宾、定、状、补，强调谓语用助动词do, does, did; 强调主语、宾语、状语用强调句。(1)助动词对比：I w

3、ant to change this situation, but I dont know how.I do want to change this situation, but I dont know how.(1)do常用来强调句子的谓语动词，意为“的确；务必，一定要”(2)注意，句子的时态变化都要表现在do上，如did, does,它后面要接动词原形。Eg：I do believe that he is an honest man.She does like literature.(2)强调句It is/was+被强调部分+that/who注意：当被强调部分是人时，其后连接词用that/

4、who都可以。 当被强调部分是物时，其后连接词只能用that。Eg: I met Mary on my way to school last night. It was Mary that/who I met on my way to school last night.（强调宾语） It was I who/that met Mary on my way to school last night.（强调主语） It was on my way to school that I met Mary last night.（强调地点状语） It was last night that I met

5、Mary on my way to school.（强调时间状语）3.“这是某人第几次做某事”句型It/This/That is the first/second time that sb have/has done sth. 这是某人第几次做某事。It/This/ That was the first/secondtime that sb had done sth. 这是某人第几次做某事。注意：it可以用this, that 来代替。重点：当先行词被序数词和形容词最高级修饰时，其后定语从句具有以下两个特点。（1）用关系代词that引导，作宾语时可以省略。（2）定语从句的时态要用完成时：主句的

6、谓语动词是is,用现在完成时；从句的谓语动词是was,用过去完成时。Eg: It is the third time that he has failed the exam. He was the strictest teacher that we had ever met.4.it作形式主语，真正的主语是doing. Its no pleasure doing sth.做某事没有乐趣。Its no fun doing sth.做某事没有乐趣。 Its no use doing sth.做某事没有用。 Its no good doing sth.做某事没有好处。 Its a waste of

7、time/money doing sth. 做某事是浪费时间/金钱。5.it作形式宾语 (6123模式) 名词 to do sth.Sb find + it + 宾补 +真正的宾语 doing sth 形容词 从句 consider, feel, think, make, believeEg：We found it possible to finish the work in ten minutes. He made it a rule to get up before seven in the morning.注意：find/found/found feel/felt/felt think/

8、thought/thought make/made/made 6. more than 的用法(1)more than与数词连用，表示“超过，不止”，相当于over.(2)more than+名词/动名词V-ing，“不仅仅是.”(3)more than+形容词/副词: 非常；十分，与very连用。(4)“more than one+单数名词,many a+单数名词”作主语，谓语动词用单数。Eg:More than one person is involved in this.Eg: As far as I know, he is more careful than the others.7.

9、名词性从句中的虚拟语气在这些词后的宾语从句、表语从句，同位语从句和主语从句中都应用虚拟语气，即should +do，其中should可省略。在这些词后的宾语从句、表语从句，同位语从句和主语从句中都应用虚拟语气，即should +do，其中should可省略。在 “一坚持”insist “二命令”order, command “三建议”suggest,advise,recommend “四要求”request,require,ask, demand 外加一个“督促”urgeEg:The teacher requested that the students should be well prep

10、ared for the coming exam.注意点1：(1)insist 后跟that引导的宾语从句表示“坚决要求，坚决主张”时，谓语动词要用“should+动词原形”，should可以省略。insist on sth 或insist doing sthEg: I insisted that we (should) tell this to her.(2)insist若表示“坚持认为，坚持说”的意思时，宾语从句多用陈述语气。Eg: He insisted that he had never stolen anything.注意点2：若suggest 表示“建议”，则其后接的that 从句

11、，谓语通常用“(should )+动词原形”这样的虚拟语气形式。若 suggest 表示“暗示，意指，表明”等，则其后接的that从句要用陈述语气。Eg: Some classmates suggest we should go to places of interest nearby.Her expression suggested that she was angry.8.be+adj.+不定式：When I told her the air would be hard to breathe and it would be very cold, she said it would be a

12、n interesting experience.“the air would be hard to breathe”为“主语+系动词+形容词+不定式”结构，此处为不定式的主动形式表被动的意义。该结构出现要有两个前提：(1)常用形容词有：difficult, hard, easy, comfortable, pleasant, interesting, exciting等(2)不定式中的动词和句子的构成逻辑上的动宾关系。(3)主语+be+adj.+不定式. 主语+be+too+adj.+不定式. 主语+be+adj+enough+不定式.The water isnt fit to drink.

13、The question is difficult to answer.9.once的用法Once she has made up her mind, nothing can change it.(1)该句是主从复合句，once引导条件状语从句，意为“一旦.就.”。但是因once引导的是条件状语从句，所以从句不能用将来时态，而用一般时态代替将来时。（主将从现）Eg:Once you start, you will never give up.once作为连接词引导条件状语从句时，后面接现在分词表示与主语是主动关系；接过去分词表示与主语是被动关系。Eg:Once printed, this di

14、ctionary will be very popular.(2)once用作副词时，意为“一次；曾经”。Eg: He once lived in the countryside.4.A determined person always tries to finish the job, no matter how hard it is.“no matter +疑问词” “疑问词+ever”(1)no matter +疑问词 只能引导让步状语从句(2)疑问词+ever 可引导让步状语从句，也可引导名词性从句（在从句中要充当一定的成分）No matter what you do, you must

15、 do it well.(让步状语从句)10.as if/ as though的用法It seemed as if the world was at an end!句式分析：这是一个主系表句式，seemed是系动词，as if 是表语从句。考点提炼：as if 和as though（1）as if/as though“似乎，好像”可用来引导表语从句和状语从句。（2）当说话者认为句子所述的是真实的、极有可能发生的或存在的事实时，as if 从句要用陈述语气。如： It looks as if it is going to snow.（3）当说话人认为句子所述的是不真实的、极少可能发生或存在的情况

16、时，从句要用虚拟语气。a. 如果从句表示与现实事实相反，谓语动词用一般过去时；b. 如果从句表示与过去事实相反，谓语动词用“had+过去分词”；c. 如果从句表示与将来事实相反，谓语动词用“would/could/might+动词原形”。Eg: The woman loves the children as if she _(be)their mother.He talks about Rome as if he_(be)there before.He opened his mouth as if he _(say)something.11.all.not/not.all等表示部分否定，其意思

17、是“并非所有的”All hope was not lost.并没有丧失所有的希望。句式分析：该句为不完全否定，all.not/not.all等表示部分否定，其意思是“并非所有的”考点提炼：（1）all, both, each, every, everyone, everybody, everything, always, whole, entirely, altogether等具有总括意义的词语与否定词连用，构成部分否定。（2）当表示完全否定意义时，英语中常用no, none, nobody, nothing, no one, neither等词语谓语动词的肯定式连用来表达。None of u

18、s was allowed to go there.12.as的用法3.As you know, this is the day the quake happened.(1)as you know在本句中是非限制性定语从句，修饰后面的整个句子。(2)as和which引导非限制性定语从句的区别：as引导的非限制性定语从句可以放在主句之前、主句之后，甚至还可以分隔主句。which引导的非限制性定语从句通常位于所修饰的句子之后；as常常有“正如、正像”的含义；which常译为“这，这件事”；当主句和从句之间存在着逻辑上的因果关系时，关系词往往只能用which。which引导的非限制性定语从句常位于所

21、s a time when women are not allowed to go to school.15.only的倒装Only then did we decide to answer violence with violence.only 放在句首，修饰副词、介词短语或状语从句，要进行部分倒装。将助动词或系动词提前，放在主语之前。Eg：Only in this way _the problem on time.只有这样我们才能按时解决这个问题。名师点睛：（1）当only修饰状语从句时，主句部分倒装，被only修饰的状语从句部分不到装。（2）only不置于句首不倒装；（3）当only修饰

22、主语时，则不用倒装。Eg：Only the teachers are allowed to use this room.Only if 只要；只有。引导的状语从句在句首时，主句要用倒装语序。If only 要是.就好了。引导的状语从句使用虚拟语气，表达对现在、将来的愿望或与过去事实相反的愿望。16.情态动词+have done must have done 过去一定做过某事may/might have done 过去可能做过某事can/could have done 本可以做某事而没做cant/couldnt have done 过去不可能做.neednt have done 过去做了不必做的
