教学过程
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 the composition on the
screen.
[设计说明] 欣赏高考满分范文，找出美丽的句子，能够很快地引起学生的兴趣，活跃课堂气氛，而且带有限制性定语从句和非限制性定语从句的出彩句子的出现，也为复习定语从句做好了准备。
Step 2 Revision
1．Revise the characteristics of non－restrictive attributive clauses.(The students can say that in Chinese.)
从形式上看，非限制性定语从句与先行词(被定语从句修饰的名词或代词)之间有逗号。
从功能上看，非限制性定语从句对先行词起着补充说明的作用，如果去掉从句，不会影响到整个主句的意思。
Revise the differences between restrictive and non－restrictive attributive clauses.
从形式上看，限制性定语从句与先行词(被定语从句修饰的名词或代词)之间没有逗号。
从功能上看，限制性定语从句对先行词起着限制解释的作用，如果去掉从句，会影响到整个主句的意思。
2．Revise the usage of non－restrictive attributive clauses.
引导非限制性定语从句的关系代词有as，which，who, whom，whose等，作定语从句的主语、宾语、表语及定语。关系副词有when，where等，作定语从句的状语。关系代词和关系副词在定语从句中一般不能省略。
(1)which引导的非限制性定语从句来说明前面整个句子的情况或主句的某一部分，that不能用于引导非限制性定语从句。
例如：
Her house，which was built a hundred years ago，stood still in the earthquake.
(2)当先行词是专有名词或被物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的。
例如：
Charles Smith，who was my former teacher，retired last year.
(3)as，which引导指代主句内容的非限制性定语从句时，表依据、评论与表事实、状态等没有多大差别，用在主句末时，有时可以通用。
He is quite pleased，as /which can be seen from his face。
但是，上面句中把定语从句置于主句句首时，就只能用as。
(4)“n./pron./num.＋prep.＋ which”定语从句
China has thousands of islands，the largest of which is Taiwan.
[设计说明] 借助第一环节中的句子，先让学生找出限制和非限制性定语从句，再复习非限制性定语从句的特征，区分与限制性定语从句的不同，为下面的环节——非限制性定语从句的运用打下基础。
