(where 引导定语从句，修饰the place)
3)He is such a good teacher as all of us love and respect.
(as 引导定语从句)
4)He is such a good teacher that we all like him.
(that引导结果状语从句,such…that… “如此…以致…”)
3． 定语从句与主语从句。试比较：
1) As is known to us all, paper was first made in China.
(as 引导定语从句，指代整个主句内容，可置于句首)
2) It is known to us all that paper was first made in China.
(it 做形式主语，代替that 引导的主语从句)
Cf. What is known to us is that paper was first made in China.
4．定语从句与强调结构。试比较：
1)It is the house where I met the young man.
(where 引导定语从句，修饰house，where在定语从句中作地点状语)
2)It was in the house that I met the young man.
(本句为强调结构，可还原为I met the young man in the house.)
5．定语从句与并列句。
请分析下列题目并分析：
A．whom B．themC．theyD．who
1）Mr Smith has three sons，none of ＿＿＿＿ is a computer expert．
2）He has three sisters，＿＿＿＿＿ are doctors．
3）She has three CDs，but none of＿＿＿＿＿ is interesting．
4）I have many friends，and all of＿＿＿＿＿ are nice and friendly．
5）Miss Yang has some relatives here；＿＿＿＿ like her very much．
［答案与简析］本组题考查定语从句与并列句的区别。第1和2小题是定语从句，正确答案分别是A和D；第3和4小题有并列连词but和and，为并列句，每句只能有一个连接词，故正确答案均为B；第5小题中的前后两部分用分号连接，是两个并列分句，无需连接词，故C项正确。
