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

B

解析:

B。devote…to… 的意思是“把……貢獻(xiàn)給……”或“致力于……”，其中 to 是介詞，不是不定式符號，若后動詞要用動名詞。句中的 he had 為定語從句，用以修飾 all，注意不將 had to 視為同一個語義結(jié)構(gòu)。
