注意：
1 关系代词和关系副词ቤተ መጻሕፍቲ ባይዱ定语从句中都要 充当句子成分。 2 当关系代词充当动词和介词的宾语时可省略， 但如果介词提前的话，不可以用 that, 而且不可 以省略。
3 定语从句中的谓语动词要和先行词保持一致 注意：one of +名词的复数 the only/the just/the very+one of+名词复数。 4 定语从句分为限制性和非限制性两种。 5 非限制性定语从句中的关系词不可以省略。
(that/which) 例4: The question_______________ I don’t understand is about grammar.
指物: that/which (宾语,可省略)
我所喜欢的科目是地理。 我不擅长的语法是定语从句。 The subject (that/which)I am fond of is geography. The grammar(that/which)I am not good at is the attributive clause.
注意：
① whom, which 作介词宾语时，介词一般可放
在关系代词之前，也可放在原来的位置上；但是
在含有介词的动词固定词组中，介词只能放在原
来的位置上。
This is the person whom you are looking for.
② which还可以引导非限制性定语从句， 指代前面整个句子或者某个词。 1.I have lost my pen, which I like very much. 2.She was awarded a gold medal, which the whole family considered a great honor. 3.She is always late for class, which makes the teacher angry.
(whom/that) 例2: The boy_________________ the nurse is looking after is my friend. 指人: whom/that(宾语,可省略)

★注意 在下面几种情况下必须用that引导定语从句。
⑴ 先行词是不定代词all, few, little, much, something, nothing, anything 等。
All that we have to do is to practise every day. Something that we heard was of great truth. 当先行词是all, everybody, nobody, anybody等不定 代词时，如关系代词在从句中当主语，则优先选用who 连接主从句。 Anybody who refused to bow was thrown into prison without trial. Everybody who were willing to see the film signed their names here.
3、由that引导的定语从句。
常规情况下：that在从句中可以指人或物，在从句中做主 语或宾语。
但：1.that不能放在介词后面作介词的宾语。 This is the school in that you will study. ( × ) This is the school in which you will study. (√) This is the school (which/that) you will study in. (√) 2.that也不可以引导非限制性定语从句。
