(2) 先行词是不定代词all, few, little, much, something, nothing, anything等时；
(3) 先行词被序数词或形容词的最高级所修饰时； (4) 先行词既有人又有物时；
(5)主句中有疑问词which 时，为避免重复；

(2) 介词后接which (注：先行词为人的话用whom)；
(3）当先行词为集体名词时，着眼于整体，用which（如着眼于
各个成员，用who）；

句中也
用which;

(1)当先行词为one, he, those, anyone及people并且前面那些代词指人时;
Those who break the law will be punished . Anyone who breaks the law will be punished.
He who doesn’t reach the Great Wall is not a true man.
(2) 表示人的先行词后有插入语时及在分隔式定语从句中先行词
为人的话用who/whom而不用that ;

come tomorrow who will teach you maths.
考点4：先行词为人时，只用that的情况：
(1)主句中有疑问词who 时，为避免重复;
Who is the man that is talking to Mr. Smith at the gate? (2) 在限制性定语从句中，当先行词在定语从句中作表语时，只用that;

(1) as引导非限制性定语从句，说明整个主句的内容，可置于句
首或句中。有“正如”之意（as is mentioned/ shown/ known, as is the case, as follows等），而which则没有此意,并且which只能用于逗号后面；
（2）as表示 “正如”，所以当从句中表示否定时或有否定前缀时，
用which而不用as:
