必修一Unit4 语法定语从句定语可以由形容词、名词、代词、数词、分词(现在分词或过去分词)、副词、不定式(短语)以及介词短语等来充当,也可以由一个句子来充当。
充当定语功能的句子称为定语从句。
定语从句所修饰的名词或代词叫作先行词。
定语从句一般用关系代词或关系副词来引导,关系词放在先行词与定语从句之间起连接作用,同时在从句中充当某种成分。
1.关系词引导定语从句的关系代词和关系副词具体见下表:2.关系代词的用法关系代词指代先行词,在定语从句中作主语、宾语、表语、定语。
在从句中作宾语时,关系代词常可省略。
(1)that的用法that 指人或物,在从句中作主语、宾语或者表语,但that不用于引导非限制性定语从句。
Campers, in my eyes, were people that/who enjoyed insect bites, ill- cooked meals, and uncomfortable sleeping bags.在我看来,露营者是喜欢蚊虫叮咬、难吃的饭菜和不舒服的睡袋的人。
( that/who在从句中作主语,不能省略)John is no longer the person ( that/who/whom) I knew five years ago.约翰不再是我五年前认识的那个约翰了。

定语可以由形容词、名词、代词、数词、分词(现在分词或过去分词)、不定式(短语)、介词短语等来充当,也可以由一个句子来充当。
充当定语功能的句子就是定语从句。
二、定语从句三要素1. 先行词:被修饰的名词/代词/整个主句2. 关系代词:连接先行词与定语从句(that, which, who, whom,whose)3. 关系副词:连接先行词与定语从句(where, when, why)注意:关系代词/副词的选择→看定从是否完整句子完整→用关系副词缺少成分→用关系代词定从=先行词+关系词+从句例:I know the girl. The girl is in red. (两个简单句)→I know the girl who is in red. (定语从句)例句中被修饰的词是the girl, 这个词就称为先行词。
其中连接两个句子的是who,称为关系词。
关系词在从句中指代先行词,并在从句中充当一定的成分,观察上句,关系词在从句中充当主语。
☆总结:关系词有三个作用:(1)连接定语从句; (2)、指代先行词;(3)、在从句中充当成分关系词的用法如下表:三、关系代词的用法:定语从句中缺少主语、宾语、表语、定语用关系代词。
在从句中作宾语时,关系代词常可以省略。
1.that的用法that指人或物,在定语从句中可作主语、宾语或表语,但that不用于引导非限制性定语从句。
例:The letter that I received was from my father.The girl that has long hair is my sister.The city is no longer the one that it used to be.注意:用that不用which的情况2.which 的用法which指物,在从句中作主语或宾语。

△动词不定式作后置定语动词不定式可以做后置定语,修饰前面的名词或代词,一般强调动作将要发生。
Have you got anything to send?I have nothing to say.△不定式与所修饰词间的关系可有一下4种:⑴主谓关系被修饰的名词或代词实际上是不定式的逻辑主语。
如:We need someone to help with the work. (someone will help with the work)⑵动宾关系被修饰的名词或代词是动词不定式的逻辑宾语。
如:I have many letters to write. (to write many letters)⑶同位关系不定式与所修饰的名词指的是一回事。
如:We have made a plan to learn from Lei Feng.⑷状语关系被修饰的名词实际上表示动词不定式动作的方式、时间等。
这些名词多是抽象名词。
如:That's the way to do it. 那样做才对。
I have no time to go there. 我没有时间去那儿。
△作定语的不定式如果含有不及物动词,且不定式所修饰的名词或代词表示地点、工具等,不定式后需要有相应的介词,但当不定时所修饰的名词是time, place 或way时,不定式后的介词通常省去。
Please give me a knife to cut with.Mary had no money and no place to live.△辨析:动名词、现在分词做定语⑴动名词作定语时,和它所修饰的名词之间没有逻辑上的主谓关系,只表示被修饰名词的一般用途,必须位于名词之前。
