Question

To do the work more successfully,____we need is more
A.only what
B.all what
C.all that
D.only

Answer 1

原句意思是：为了把工作做得更好,我们需要更多（的支持等）.
前半句是一个目的状语.
后半句：...we need is more中,主语的构成不完整.所以可以直接使用what,构成what we need(这就成了一个主语从句,所以楼上所谓“定语从句”的说法是错的).但是选项中的All what等等都是不合适的表达.都不能选,排除A B.
另外,在名词性（主语从句即名词性从句的一种）从句中,all that+从句＝what+从句.
例如：What we did is to protect the boy就等于All that we did is to protect the boy.
所以应该用all that,选C.
再次声明,题目中是一个主语从句.（突然想起来了,what就根本不能用于定语从句,楼上错完着呢）
如有不明之处请补充.
希望对你有所帮助!
