Question

Mr．Reed made up his mind to devote all he had to ________ some schools for poor children．

[　　]

A．

set up

B．

setting up

C．

have set up

D．

having set up

Answer 1

答案：A
解析：

可能会因为“he had to”而选择A项，因为对had to do sth．的结构太熟悉了。其实，句中had to与set up并不构成搭配，因为he had为定语从句修饰先行词all，set up与devote all…to构成搭配，即devote all to setting up(to为介词)。
