定语从句关系代词和关系副词的确定.docx

定语从句关系代词和关系副词的确定： 将先行词放入定语从句中看它做什么成份， 如果作动词或者介词的宾语，那么肯 定应该是使用关系代词，如果需要加上介词之后作状语，那么就应该使用关系副 !词。 定语从句应用要点：一、介词+which/whom 1、 介词的选择与主句中先行词的搭配密切相关 This is the factory which his father once worked. That s the reason which he was late It is the book which I paid 8 yua n. 2、 whose +n. = n.+ of whom/which The house whose roof was damaged has bee n repaired. = The house, the roof of which was damaged, has bee n repaired. 二、在下列情况中定语从句引导词只能用 that，而不能用which : 1、 先行词既有人又有物时 The boy and the dog that are in the picture are very lovely. 2、 先行词由不定代词充当： all, something, anything, nothing, any, some …All the people that are prese nt burst into tears. 3、先行词由序数词或形容词最高级修饰 4、 先行词由限定词修饰：on ly, just, very … 5、 句中已有 who 或 which，为避免重复 Who is the man that is talking to him? Which of the books that you bought is easy to read? 三、 非限制性定语从句中，不能用关系代词 that，作宾语用的关系代词也不能省略。例如： There are about seve n millio n people tak ing part in the elect ion, most of whom are well educated. 四、 which的用法 1、 如果作先作词的集体名词着眼于集体的整体，关系代词用 which;若是指集体中的各个成 员，则用who。 2、 它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种 从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与 and this相似，并 可以指人。例如： He succeeded in the competiti on, which made his pare nts very happy 五、 from where为 介词+关系副词 结构，但也可以引导定语从句。例如： We stood at the top of the hill, from where we can see the town.. 六、 that可引导定语从句表示时间?地点或原因 That有时可以代替关系副词 when, where或者why引导定语从句表示时间.地点或原 因，在that引导的这种定语从句中，that也可以省去。 七、 as引导限定性定语从句： 先行词有the same such, so修饰时，定语从句 用 as 弓丨导： He is such a good boy as we all like. I like the same book as you do. 八、 定语从句中的主谓一致问题：（从句中谓语单复数要遵循先行词）I, who a stude nt, have to do my best to 名词性从句：它们在主句中充当主语、表语、宾语或同位语，都不能用逗号与主句分开。（注: 句中划线部分为从句） 蛀语从句 1、 定义：先找到句子的谓语，主句的谓语前面的从句，叫做主语从句。 Why he left was nt importa nt.（was nt 是主句的谓语动词， why he left 做主语从句） That she became an artist may have bee n due to her fathers in flue nce.（may have bee n due是主句的谓语动词， that she became an artist 做主语从句） 2、 借助形式主语it,主语从句放在后面 由that引导的主语从句可以放在主语的位置， 这时that不可以省略。例如：That prices will go up is certa in. that主语从句放在句首的
