Question

you should take out all that you have.分析一下该定语从句的句子

Answer 1

all 是先行词，必须用关系代词that，all that =what.
all在从句中做句子的宾语，所以可以省略。
定语从句可以拆成两个分句：1.you should take out all.
2.you have all.
定语从句中，必须用关系代词的情形：
1.当先行词是不定代词all ,much ,little ,something ,everything ,anything,nothing,none ,the one 时。例如
do you have anything that you want to say for yourself?
you should hand in all that you want.（和我们前面说的是一个情形）
2 当先行词前面有the only,the very ,any ,few ,little ,no,all 等词修饰时。如
This is the vey bus that I am waiting for.very 是恰好，正好的意思)
3.当先行词是形容词最高级或先行词的前面有最高级修饰时。
This is the most interesting film that I have ever seen.
4.当先行词是序数词或有它修饰时。
What is the first American film that you have seen?
5.当先行词既有人又有物时。
Do you know the things and persons that they are talking about?
6.当主句的主语是疑问词who or when 时。
Which is the bike that you lost?
7.有两个定语从句是，其中一个关系代词应该用which,另外一个应该用that。
They secretly built up a small factory,which produced things that could cause pollution.
8.当先行词在句中作表语，而关系代词在从句中也作表语时。
shanghai is no longer the city that it used to be.
shanghai is no longer what it used to be .(更常用)

从句中引导词that代all 在从句中做宾语，可省略
