14、形容词性从句（即定语从句） 、副词性从句（即状语从句，包括时间，结果，条件，目的，原因，让步，地点，方式等）1、 主从作主语，例：That the earth is round is truth.2、 宾从作宾语，例：Do you know where he lives?3、 表从左表语，：My opinion is that you should not go alone.(一)主语从句一、1、定义：作句子主语的从句叫做主语从句。2、引导词：主语从句通常由从属连词 that,whether,if 和连接代词what,who,which,whatever,whoever 以及连接副词 how,
15、when,where,why 等词引导，that 在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例：(1)What he wants to tell us is not clear.他要跟我们说什么，还不清楚。(2)Who will won the match is still unknown.谁能赢得这场比赛还不得而知。(3)It is known to us how he became a writer.我们都知道他是如何成为一名作家的。(4)Where the English evening will be held is
16、 has not yet been announced.英语晚会将在那里举行，还没有宣布。二、1、找主语从句时，先找到句子的谓语，主句的谓语前面的从句，就是主语从句。(1)Why he left wasnt important.主语从句 主句的谓语动词(2)That he became an artist may have been due to her fathers influence.主语从句 主句的谓语动词2、that 引导的主语从句可以放在主语的位置，这时 that 不可省略。例：That prices will go up is certain.3、that 主语从句放在句首的情况

18、从句后的谓语动词一般用单数形式。常用句型如下：(1)It+be+名词+that 从句(2)It+be+形容词+that 从句(3)It+be+动词的过去分词+that 从句(4)It+不及物动词 +that 从句注意：主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“should+do” ，常用的句型有：(1)It is necessary(important,natural,strange,etc)that(2)Its a pity(a shame,no wonder,etc)that(3)It is suggested(required,proposed,des
19、ired,etc)that5、wh-疑问词引导的主语从句，可以放在句首(1)，也可以借助形式主语 it(2)。(1)When hell be back depends much on the weather.How it was done was a mystery.Whether well succeed remains to be seen.(2)It is uncertain whether the game will be held.Its a puzzle now life began.It doesnt matter much where we live.Is it known w
20、here he went?（二）定语从句一、1、定义：修饰一个名词或代词的从句称为定语从句，一般紧跟在所修饰的先行词后面。2、关系词：引导定语从句的关联词称为关系词。关系词有关系代词和关系副词。关系代词有 that,which,who,whom,whose,as 等；关系副词有 where,when,why 等。关系词常有 3 个作用：（1）引导定语从句， （2）代替先行词， （3）在定语从句中担当一个成分。二、关系代词引导的定语从句：1、who 指人，在从句中作主语。(1)The boys who are playing football are from Class One.(2)Yers
21、terday I helped an old man who lost his way.2、whom 指人，在定语从句中充当宾语，常可省略。(1)Mr. Liu is the person whom you talked about on the bus.(2)Mr. Ling is just the boy whom I want to see.注意：关系代词 whom 在口语和非正式语体中常用 who 代替，可省略。(3)The man who/whom you met just now is my friend.3、which 指物，在定语从句中作主语或者宾语，作宾语时可省略。(1)Football is a game which is liked by most boys.(2)This is the pen which he bought yersterday.4、that 指人时相当于 who 或者 whom；指物时，相当于 which。在宾语从句中作主语或者宾语，作宾语时可省略。(1)The number of the people that/who come to visit the city each year rises one million.(2)Where is the man that/whom I saw this morning?
