Step 1 Presentation

1. Enjoy a beautiful composition which comes from the 2008 Zhejiang college entrance examination.

I prefer my English classes to be taught in both English and Chinese, whose advantage is that it is easy for us to understand what the teacher talks about. The teacher first teaches the class in English, and then she explains those that are hard to understand to us so that we get a better understanding of the passage. That will be good for us.

However, teaching the class in two languages will make the English atmosphere not so strong. Some students who wish to be taught in English will be disappointed.

Except for the disadvantage, I think it is really good to hear two languages in class. It can make us more familiar with the foreign culture.

2. Show the sentences with the restrictive and non-restrictive attributive clauses in composition on the screen.

Step 2 Revision

语法基础:

一. 限制性定语从句与非限制性定语从句的区别: 限制性定语从句是先行词在意义上不可缺少的定语，如果去掉, 主句的意思就不完整或失去意义. 从句与主句关系十分密切，写时不能用逗号隔开; 非限制性定语从句与主句的关系不是十分密切，只起到附加说明的作用, 去掉后主句的意思仍然很明确. 从句与主句之间往往用逗号隔开，一般不用that.

She has found the necklace (that) she lost two weeks ago.

The accident happened on the day when I lost my job.

Jack, who speaks Spanish, works in China.

Yesterday I met Li Ping, who looked very tired.

Mum treats me like a baby, which I can't bear.

He said he had been working in the office for several hours, which was true.

Tom always fails in the examination, which makes his parents upset.

二. 非限制性定语从句引导词的选择

1. 关系代词和关系副词的选择: 非限制性定语从句中, 关系代词和关系副词的选择的方法和限制性定语从句相同. 关键是关系词在从句中充当的成分. 如果
