1.Finally ，the thief handed everything _____ he had stolen to the police.(MET'87)
A.which B.what C.whatever D.that
2.All _____ is needed is a supply of oil.(MET'89)
A.the thing B.that C.what D.which
答案及简析：
1.D。2.B。that和which都能指物，在定语从句中作主语或宾语，但下列情况下，常用that，不用which：①先行词是all， everything，anything，nothing等不定代词。②先行词指物且被形容词最高级、序数词或all，no，only，the very，the last等修饰。③先行词既指人又指物。
二、考查关系代词whose
3.A child _____ parents are dead is called an orphan.(MET'86)
A.which B.his C.whose D.with
答案及简析：
3.C。关系代词whose在定语从句中作定语，修饰其后的名词，意为“……的”。有时“whose +n.”可转换为“n.+of+which /whom”。如：
The building whose roof(=the roof of which)we can see from here is a hotel.
This kind of book is for the students whose native language(=the native language of whom)isn't English.
三、考查关系代词与关系副词的差异
4.After living in Paris for fifty years he returned to the small town _____ he grew up as a child.(NMET'96)
A.which B.where C.that D.when
5.I also enjoyed the evenings when we spent together.(NMET'95短文改错)
答案及简析：
4.B。5.去掉when或when→that/which。如何选用关系代词和关系副词呢?关键是看先行词在定语从句中作什么成分。决不能只按先行词是地点名词就用 where，先行词是时间名词就用when，先行词是reason就用why。有时，命题者还会在先行词与引导词之间加入附加成分，影响考生正常解题思路，做题时，要特别注意。
四、考查“介词+关系代词”
6.He paid the boy $10 for washing ten windows， most of _____ hadn't been cleaned for at least a year.(MET'90)
A.these B.those C.that D.which
答案及简析：
6.D。“介词+关系代词”引导的定语从句，关系代词一般只有which，whom。先行词是物时，用which，先行词是人时，用whom。介词的选定一般依据下列三点：①看定语从句中的形容词与哪一个介词组成固定搭配②看先行词与哪一个介词组成习惯搭配③看定语从句中的动词与哪一个介词组成习惯搭配。
五、考查非限制性定语从句与限制性定语从句的区别
7.Dorothy was always speaking highly of her role in the play，_____ ，of course，made the others unhappy.(NMET2000)
A.who B.which C.this D.what

六、考查as引导的非限制性定语从句
9._____ is known to everybody，the moon travels round the earth once every month.(NMET2001)
A.It B.As C.That D.What
答案及简析：
9.B。as，which均可用来引导非限制性定语从句，代替整个主句，但as引出的从句可放在句首、句中或句末，which引出的从句通常只能放在主句后面。
