定语从句特定选择
关系词
1、只用that不用which
1.当先行词是序数词或被序数词、最高级，关系词用that。
2.当先行词既有人又有物时，用that。
3.当先行词带有the only,the very,the same,the last,the one等词时，用that。
4.当主句中有who或which时，为避免重复用that。
5.当先行词为something，anything，nothing，none，no，little，much，all等不定代词时用that。
2、只用who不用that
1.如果先行词是those,they,all,persons,people,he,anyone,one时用who
2.当先行词指人并含有较长的后置定语从句或在被分割的定语从句中时。
3、只用which不用that
1.当主句先行词后有介词时，用which。例：This is the one of which I'm speaking。
2.非限定性定语从句，用which。
3) 描述句中一般用which。例：Beijing，which was China's capital for more than 800years。

定语从句误区提醒
1.当表示时间或地点的名词作先行词时，要判断出它们在从句中作状语还是主语或宾语。作状语时用关系副词，反之用关系代词。
典型例题：I can never forget the day xxxxxxx we worked together and the day xxxxxx we spent together.
A. when; which B. which; when C. what; that D. on which; when
答案：A
解析：两个先行词the day都是表示时间的名词,但第一个空白处要填的`关系词在从句中作状语,因此要用关系副词when. 第二个空白处要填的关系词在从句中作动词spent的宾语,因此要用关系代词which或that来引导定语从句.
2.当主语为物时，不能用what
3.there be句型中，指人用who指物用that。
4.当主句中缺少主语或表语时，用the one。
5.当出现先行词+介词时，关系词只能用whom或which
6.当出现先行词+介词时，注意判断介词与从句谓语是否有关系，以确定为定语从句
