_新教材高中英语Unit3CONSERVTIONSectionⅢGrammar__定语从句
(2) 关系代词替代情况不同 关系代词 whom 在限制性定语从句中作宾语时可用 who 代替， 但 whom 在非 限制性定语从句中作宾语时不可用 who 来代替。
This is the girl (whom/who) I met in the street. 这是我在街上遇到的那个女孩。
This is Jack, whom you haven't met before. 这是杰克，你以前没见过。 [名师点津] 在限制性定语从句中， 先行词指人时可用 that 代替 who/whom, 但在非限制性定语从句中先行词指人时， 不可用 that 代替 who/whom. 误：She has a sister, that is a teacher. 正：She has a sister, who is teacher.
三、限制性定语从句和非限制性定语从句的区别 1．在句中作用不同 (1)限制性定语从句对被修饰的先行词有限定制约作用， 使该词的含义更具 体， 更明确。
限制性定语从句不能被省略，否则句意就不完整。
Do you remember the boy who played football yesterday? 你还记得昨天打篮球的那个男孩吗？ (2)非限制性定语从句与先行词关系不十分密切， 只是对其作一些附加说明， 不起限定制约作用。 如果将非限制性定语从句省去，主句的意义仍然完整。
③The reason _w_h__y_he won the first place in the competition is that not
only did he follow the teacher's advice, but also he trained hard.

All depends on
翻译句子
We must never think(that)we are good in everything and that others
are good in nothing. 翻译
答案:我们绝不能认为自己什么都好,别人什么都不好。 (3)主句谓语动词与that之间有插入成分时,that不可省略。 单句填空
答案:他告诉我,如果必要的话,他们就通宵工作。 (5)有it作形式宾语时,宾语补足语之后由that引导的宾语从句不可 省略that。 单句填空
We think
highly probable that he is dead.
我们认为他很有可能死了。
答案:it
(6) that引导的宾语从句中,that之后紧接着有作主语或作定语的 this/that时,that不可省略。
the first place in the bicycle race. 宾语从句: 答案: whoever wins the first place in the bicycle race
注意:动词find,consider,think,feel,believe,make等后有宾语补足语 时,常用it作形式宾语,代替宾语从句原来的位置,而将真正的宾语从 句后置。有些动词(短语),如enjoy,love,like,hate,appreciate,take,hide, insist on,depend on,rely on等引导宾语从句时,习惯上直接在从句前 加形式宾语it。
