一、用关系从句改写句子
1. There should be an e-teacher. The e-teacher can correct mistakes and offer suggestions.
There should be an e-teacher correct mistakes and offer suggestions.
2. That is his old house. He lived there for twenty years.

3. The young man in a new suit looks very handsome.
The young man a new suit looks very handsome.
4. The movie has a happy ending and I like this kind of movie.


5. The woman is our English teacher. She is talking with some students.

1. who/that can
2. in which
3. that/who wears
4. I like the movie that/which has a happy ending.
5. The woman who/that is talking with some students is our English teacher.

【分析】本题考查定语从句的应用，解题思路为：1. 找出两个简单句中共同修饰的名词，即先行词；2. 根据先行词的类型（人/物）和从句结构，选择合适的关系词（关系代词who/that/which，或“介词+关系代词”结构）；3. 调整从句谓语动词形式使其与先行词匹配，最终合并为含定语从句的复合句。
【解析】1. 先行词是表示人的名词“e-teacher”，关系代词用who或that，从句谓语为“can correct”，故填who/that can；2. 先行词是表示地点的名词“old house”，从句动词live需搭配介词in，因此用“介词+关系代词”结构in which；3. 先行词是表示人的名词“young man”，关系代词用who或that，从句谓语用第三人称单数形式wears，故填that/who wears；4. 先行词是“the movie”，关系代词用that或which，合并为“I like the movie that/which has a happy ending.”；5. 先行词是“the woman”，关系代词用who或that，合并为“The woman who/that is talking with some students is our English teacher.”。
【答案】1. who/that can
2. in which
3. that/who wears
4. I like the movie that/which has a happy ending.
5. The woman who/that is talking with some students is our English teacher.
