In the beginning, people who bought them often got angry. (who指人，修饰先行词people,作从句的主语。)刚开始，买的人经常会生气。
They needed a plant which didn't need as much water as rice.(which指物，修饰先行词plant,作从句的主语，此处which可换为that。)
I've bought a new dictionary whose cover is blue.（这里whose指物，在从句中作定语。）
难点：（1）whose既可指"某人的"，也可指"某物的"，指物时不可想当然误用which,但可使用"the+n.+of which"的表达方法，也可用"of which +n"的表达方式。
例句：①I've bought a new dictionary, the cover of which is blue.
②I've bouth a new dictionary of which the cover is blue.
(2)在非正式文体中，当引导词who位于从句句首时，可替换whom作宾语。如：Do you know the boy who/whom we talked to just now?
1Do you know the woman with whom I shook hands at the school gate?(此处介词with之后的whom不可替换为who或that,也不能省略。)
Do you know the woman whom I shook hands with at the school gate?(此句中的引导词whom作介词with的宾语，可换为who或that,也不能省略。)
难点：（1）当who, whom, which, that等引导词在从句中作宾语而省略时，从句中不能再加宾语。如：This is the pen she bought it yesterday.(此处的it应去悼，因为作宾语的which或that已省略。)
（2）两个以上的简单句组成一个句子时，必须用关联词来连接两个句子，而不能用代词。如：This is our monitor, without him, we couldn't win the game.(此句中的人称代词him必须改为引导词whom。)
Can you see the tall building, in front of it there a large play ground?(此句中的代词it 必须改为引导词which。)
1.Have you ever been to the place which/that we visted last year
Have you ever been to the place where we worked last year?
2.Do you still remember the day which/that we spent together?
Do you still remember the day when we stayed together?
This is the first time that I've been to the museum, which I have been looking forward to for many years.
which is the book that you want to borrow?
如：I dislike the way in which/that/× he talks to his mother.
此句中way在定语从句中充当方式状语，引导词用in which that 或者省略
