高一英语知识点

1、被动语态：被动语态是动词的一种特殊形式,用来说明主语与谓语动词之间的关系。如果主语是 动作的执行者(即某人做某事),便叫主动语态；如果主语是动作的承受者(即某事被做),便叫被动语态。英语中被动语态由“助动词be +动词的过去分词”构成。助动词be有时态、人称和数的变化。被动语态后的by短语有时可省去。 (1) 被动语态的用法：A 不知道谁是动作的执行者(即不知道谁做)时用被动语态,省略by短语。如：A man was killed in the accident. B 不说或者众所周知是谁做时,用被动语态,省略by短语。如：Rice is also grown in this place. C

2、 强调动作的承受者,句尾加by短语。如：It was written by Lu Xun. 句式转换“动词+间接宾语+直接宾语”改为被动时,可以用间接宾语做被动句的主语。如： His teacher gave him a dictionary.He was given a dictionary by his teacher.也可以用直接宾语做被动句的主语,但是需用to或者for引出原句的间接宾语。如：His teacher gave him a dictionary.A dictionary was given to him by his teacher.“动词+宾语+动词原形”改为被动时,动

3、词原形前要加to.如：The boss made the poor man work 12 hours a day.The poor man was made to work 12 hours a day.“动词+介词”改为被动时,介词一般在原位不动。如：The girl takes good care of her little brother.The girls little brother is taken good care of by her.“be+过去分词”未必表示被动语态,而可能是系表结构。如：He is pleased / worried / tired /.(系表)He w

4、as hit / knocked down / told / shot / .(被动)定语从句定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般跟在它所修饰的先行词后面。关系词常有3个作用： 连接作用，引导定语从句。 代替主句中的先行词，甚至可能是主句中的一部分或者整个主句。 在定语从句中充当一句子成分。 注：关系代词有主语、宾语之分。一般whom作为宾语。关系代词在从句中作主语，宾语，表语，定语等，关系副词在从句中作地点状语，时间状语，原因状语等。 1,who, whom, that这些词代替的先行词是人的名词或代词，

5、who作主语指人，whom作宾语指人，that既可作主语又可作宾语（作宾语可以省略），可以指人也可以指物。2,Whose 用来指人或物(只用作定语, 若指物，它还可以同of which互换，指人的时候也可以用of whom 代替） 3,which, that它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，作宾语时可以省略，例如： (1)Prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在从句中作主语）4,as as 可以

6、做主语，也可以作宾语，作宾语时一般不省略，指人或者物。常与such as,the same as等短语连用。 5，as与which的区别 as可以放在句首，而which不行 as表示主观，which表示客观事实 as引导非限制性定语从句 限制性定语从句关系代词：在句中作主语、宾语或定语 1. that既可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语也可以省略。eg：This is the book （which）you want. 2. 如果which在从句中作“不及物动词+介词”的介词的宾语，注意介词不要丢

7、掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置 3. 代表物时多用which，但在下列情况中用that而不用which： 先行词是anything, everything, nothing , none等不定代词时； 先行词由every, any, all, some, no, little, few, much等修饰时，这时的that常被省略；先行词前有序数词或被形容词最高级修饰时； 先行词中既有人又有物时； 整个句中前面已有which，who,that时；当先行词为物并作表语时； 先行词为one时； 先行词同时又被the only,the very,the same

8、修饰时；在there be句型中，句子的主语是先行词，而且又是物 以here is开头的句子；It is a high time+ 定语从句 4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语 5. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与 of which 调换,表达的意思一样。 关系副词关系副词：在句中作状语 关系副词=介词+关系代词 why=for which where=in/ at/ on/ . which (介词

9、同先行词搭配) when=during/ on/ in/ . which (介词同先行词搭配) 1. where是关系副词，用来表示地点的定语从句。 2. when引导定语从句表示时间注值得一提的是，表示时间“time一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。 名词性that-从句 1）由从属连词that引导的从句叫做名词性that-从句。 That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语，例如： 主语：That he is still alive is shee

10、r luck. 他还活着全靠运气。 宾语：John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。 表语：The fact is that he has not been seen recently. 事实是近来谁也没有见过他。 同位语：The fact that he has not been seen recently disturbs everyone in his office. 近来谁也没有见过他，这一事实令办公室所有的人不安。 形容词宾语：I am glad that you are satisfied

11、 with your job. 你对工作满意我感到很高兴。 2）That-从句作主语通常用it作先行词，而将that-从句置于句末，例如： It is quite clear that the whole project is doomed to failure. 很清楚，整个计划注定要失败。 Its a pity that you should have to leave. 你非走不可真是件憾事。 用it作形式主语的that-从句有以下四种不同的搭配关系： a. It + be +形容词+ that-从句 It is necessary that 有必要 It is important th
