活动三：语境中应用定语从句
3. Wrk with a partner. Take turns t ask each ther abut the pictures. Make sentences with restrictive relative clauses using that, which, wh, whse r whm.
定语是用来修饰、限定、说明名词或代词的品质与特征的。可以由形容词、代词、数词、名词、分词、不定式、介词短语 等来担任。(以分词、介词短语为例） 例： The girl behind the tree is Kate. The man driving t fast was drunk.
定语从句在英语中，修饰名词或代词的句子叫定语从句。 例：The girl wh is behind the tree is Kate. The man wh was driving t fast was drunk.
关系代词如何引导定语从句普通代词与关系代词的区别I have a sister. She wrks in Shanghai. 代替 sister普通代词：只起代替的作用（如上例she)I have a sister wh/that wrks in Shanghai.
关系代词的作用： （如上例wh/that）
1.代替先行词; 2.它还在定语从句中担任一定的成分; 3. 同时连接先行词与它引导的定语从句。 （把主句和从句连起来）
The building is ur schl. The building stands by the river.
The building which/that stands by the river is ur schl. 先行词 关系词 定语从句
关系代词的使用取决于先行词，它们的关系非常密切，因为关系代词在定语从句中代替主句中的先行词，所以它在一般情况下都跟在先行词之后，而且和先行词一致。
which/that 是关系代词，它在从句中代替先行词the building, 同时担任从句中的主语，也起连词的作用，把两个简单句连接 起来。
最后，当关系代词做主语时，从句的谓语动词和先行词保持一致.I like t watch mvies that are scary.I prefer music that has great lyrics. 注:定语从句的时态不受主句的限制。The wman wh/that spke at the meeting yesterday is my mther. (主句)The wman is my mther.(叙述客观事实 用一般现在时) (从句)The wman (wh/that) spke at the meeting yesterday. (句中yesterday表示过去时间)
 The by is Tm. The by is smiling.
 The by is Tm. The by has a rund face.
The by wh is smiling is Tm. (主语)
The by wh has a rund face is Tm.
 The by is Tm. He sits in frnt f me.

 The teacher will give us a talk. We met the teacher yesterday.

2.whm指人,作宾语 (作宾语可省略,如 介词提前则不能省)

The man t whm I talked is Mr. Li.
3.whse 是代词的所有格形式, 它既可以代人也可以代物。

I saw a wman. Her bag was stlen .I saw a wman whse bag was stlen.
