Non-restrictive attributive clauses（非限制性定语从句）

Teaching aims 教学目标

1. Help the students to go over the attributive clause. 2.Enable the students to learn about non-restrictive attributive clauses. 3. Enable the students to tell the differences between restrictive and non-restrictive attributive clauses and use them correctly. Teaching procedures教学过程

Step1. Revision

在复合句中，用作定语的从句叫定语从句。被定语从句修饰的名词或代词叫先行词。定语从句一般放在先行词的后面, 由关系代词或关系副词引导。

Step 2. Read the passage again and underline all the sentences with attributive clauses.

Step 3. Comparison (Compare the following pairs of sentences and find the differences between them.) 1.He is one of the students who have won a scholarship. 2.Frederick William I, to whom the Amber Room belonged, decided not to keep it.

3.The gift was the Amber Room, which

was given this

name because several tons of amber were used to make it. 4.It was also a treasure decorated with gold and jewels, which took the country’s best artists about ten years to make. 5.In 2003 it was ready for the people of St Petersburg, when they celebrated the 300th birthday of their city. Step 4. Conclusion

Conclusion1: 非限制性定语从句与主句之间通常用逗号分开。

Conclusion2: 非限制性定语从句不能用that来引导，关系词可以指代整个句子。

Conclusion3: 限制性定语从句是先行词不可缺少的修饰成分，否则主句的意思不完整。非限制性定语从句只对先行词作进一步的补充说明，去掉之后主句的意思照样完整。

Conclusion4: 1.当限制性定语从句中，先行词被the same/such/as/so等修饰时，要用特殊关系代词as,其中，the same…as…“与……一样”；

the same…that…“与……同一”。

2. as 和which在引导非限制性定语从句时，两者都可代替整个主句，as 引导的非限制性定语从句可置于句首（也可

后置），而which（及其它关系词）引导的定语从句不可放在句首。

as常有“正如”的意思。

Conclusion5: 一些数词或不定代词如

all/ some/ one/ both/ neither/ none/ most等可与

of

which/whom一起引导非限制性定语从句,此时关系代词不可用that。
