2、理解、掌握、运用where，when，why与"介词+which"引导的定语从句。

3、理解、掌握、运用形容词和副词的比较。

4、理解、掌握、运用状态和动作动词。

一、课时重点

1. 关系副词where和when引导的定语从句可以提供时间和地点方面的信息。例如：

This is the place where I lost my purse.

She still remember the day when Bill first walked into her office.

2. 在reason后可用why引导定语从句。例如：

Do you know the reason why he was so angry?

Is there any reason why he is fired?

3. 介词+which/whom引导的定语从句。关系代词可作介词的宾语。通常在which和whom前加介词，即介词+which/whom结构。例如：

The train on which I am travelling is for Shanghai.

This is the professor from whom I've learned a lot.

注意：在日常英语中，通常是把介词放在从句的句末，省略关系代词which和whom。例如：

The train I am travelling on is for Shanghai.

This is the professor I've learned a lot from.

4. 定语从句有两种：限制性定语从句和非限制性定语从句。

限制性定语从句修饰限定名词或代词，清楚表明所修饰的人或物。例如：
