关系代词，在限制性定语从句中做从句中的宾语成分的时候是可以省略的。在非限制性定语从句绝对不能省略。
例如：The girl （who is ）standing there is my sister。括号里的可以省略，standing there 就做一个后置定语。
但也有几种特殊情况，关系代词不用作宾语也可以省略，同学们学习和使用时请注意。
在下列情况下,引导宾语从句的关联词可以省略。
一、that在定语从句中作表语时。例如:
She is all (that) a teacher should be. 她具备一个老师应该具备的所有条件。
二、that在从句中作补语时。例如:
I'm not the fool(that) you thought me. 我不是你以前所认为的那个傻子了。
He is the nicest teacher (that) the students consider him in their school. 他就是学生认为学校中最好的那个老师。
三、作状语时的省略。

2. 当先行词是way,且在定语从句中作方式状语时,关联词可用in which或that,也可以省略。例如:

This is the right place he was born.这儿就是他的出生地。(注意:句末不可用介词in)
同学们往往认为关系代词作宾语时就一定可以省略,其实不然.在下列四种情况下,关系代词虽作宾语,却不能省略。
一、在介词+whom /which结构中, whom, which不能省略。例如:
Do you know any shops nearby in which I can buy flowers?你知道附近有可以买到花的商店吗?
That is the headmaster with whom my father was talking just now.刚才和我爸爸交谈的那个人是校长。
二、在非限制性定语从句中,作宾语的关系代词也不能省略。例如:
Mr Green, whom you know, is the tallest in our school. 格林先生是我们学校里最高的,你也认识他。
The elephant is like a spear, as anyone can see. 大象像长矛,任何人都知道。
三、在the same ... as, such ... as, as ... as, the same... that结构中, as, that 即使作宾语,也不能省略。例如:
I have bought the same bike as you (have). (指同类用as)我买了一辆和你的一样的自行车。
This is the same book that I read the day before yesterday. 这就是我前天读过的那本书。(关系代词that如要换成as, 则指与我读的书一样,而不是同一本。)
四、当and, but, or等连词连接两个或两个以上的定语从句修饰一个先行词时,关系代词第一个可省略,第二、第三个等不可省略。例如:
This is the book (which) I read yesterday and which I found very interesting. 这就是我昨天读的那本书,它很有趣。
You have many people around you (whom) you always turn to and whom you will never forget.你身边有很多人,你经常向他们求助,你永远不要忘记他们。
