(1) 有关术语：在英语中用来修是一个名词或代词的句子叫定语从句。定语从句须放在所修饰词之后，定语从句所修饰的词叫先行词，引导定语从句的词叫关系词。
(2) 如何确定关系词
方法一：准确判断关系词在定语从句中的成分，关系词作主语、宾语，用关系代词；关系词作状语，用关系副词；关系词作定语则用whose, 或which。
方法二：看定语从句中的谓语动词是及物动词还是不及物动词。如是及物动词，用关系代词；不及物动词则用关系副词。
(3) 关系代词的一般用法：

注：定语从句中只能用that的情况：
① 当先行词是everything, anything, nothing (something 除外), all, none, few, little, some等代词时，或当先行词受every, any, all, some, no, little, few, much等代词修饰时。如：
All that can be done has been done.? 所有能做的都做好了。
There is little that I can do for you.? 我不能为你干什么。
The book contains none that interests me. 这本书没什么让我感兴趣的东西。
② 当先行词被序数词、形容词最高级修饰时。如：
The first place that they visited in London was the Big Ben.?
在伦敦他们参观的第一个地方是大本钟。
This is the most interesting book that I have ever read.?
这是我读过的最好的书。
③ 当先行词被the very, the only修饰时。如：
This is the very dictionary that I want to buy.?
这正是我要买的词典。
After the fire in his house, the old car is the only thing that he owns.?
家里发生了火灾过后，那辆旧车成了他的唯一拥有。
④ 避免重复。如：
Which is the T-shirt that fits me most?? 哪件T恤衫最合我的身？
⑤ 当先行词即有人又有动物时。如：
They talked about the persons and things that they remembered at school.?
他们谈论着他们所能记起的在校时的人和事。
Look at the man and his donkey that are walking up the street.
※ 注意
the same… as 与the same… that引导定语从句意思不同：
I have bought the same bike as you. 我买了一辆和你的一样的自行车。
I used the same book that you have. 我用的是你的那本书。

1. Leading-in
Ask Ss to match the sentences in Activity 1 and underline the different part in each pair.
2. Explanation
Give Ss some explanation to the grammatical points of relative clauses.
(1) 关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。如：
The school (which / that) he once studied in is very famous.
=The school in which (where) he once studied is very famous.?
他曾经就读过的学校很出名。
This is the boy (whom / who / that) I played tennis with yesterday. =This is the boy with whom I played tennis yesterday.
这是我昨天跟他打台球的男孩。
(2) 含有介词的短语动词一般不拆开，介词仍放在短语动词的后面。如：look for, look after, take care of 等。
This is the watch (which / that) I am looking for.???(正)??这是我正在找的手表。 This is the watch for which I am looking.??? (误)
(3) “介词+关系代词”前还可有some, any, none, all, both, neither, many, most, each, few等代词或者数词。如：
He loves his parents deeply, both of whom are very kind to him.??
他深深地爱着他的父母，他们俩待他都很好。

2，although与 while
相同点：都是连词，都可引导让步状语从句；
不同点：①although意为“虽然，尽管”，相当于though，所引导的句子通常置于句首。含although从句的复合句可以转化为由but引导的并列句，但although与but不能同时出现；②while意为“然而，但是”，可用作并列连词，表示前后的对比，一般不与but转换，所引导的句子不能置于句首。
教学后记
The Ss can’t grasp the attractive clauses.
