求助英语定从语法题

A.What little
B.So much
C.How much
D.So little
All ______ is a continuous supplying of the basic necessities of life.
A.what is the need
B.the things needed
C.for our needs
D.that is needed
..
请解释为什么其他选项是错误的...为什么第一个不选别的
第二个为什么不选B或C，从结构上来说他们也是对的啊...

老大,这是主语从句,不是定语从句.
a,
what he knows is .这个句子你能理解吧?由what引导的主语从句,意思是他所知道的,再来看看这个句子加了点什么,what he knows about it,关于那件事他所知道的,little表示程度,he knows little about it,放在前面就翻译成,关于那件事他所知道的那一点.了
d,
一样的啦,all 是先行词,关系代词用that,可以省略,这句话相当于what is needed.
补充：这两个题目都是主语从句,因为从句的成分在整个句子中充当主语.
第一题,
knows是一个动词,is 也是个动词,所以你要能识别这是一个从句.
what 在从句中作need 的宾语（need是及物动词,一定要接宾语的阿）,其他的不可以充当这个成分,.
第二题,
all 是先行词,关系代词只能用that,由于that在句子中不充当成分,可以省略.不省略也不错.B,意思上讲的过去,all本来就是个先行词了,加上the things那些就让人觉得很罗索,习惯不这样表达,Need在c中作了名词了,可是意思变成我们需要的一切是.讲不过去阿.
题目意思是,我们需要的是.
