Question

My 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：B
解析：

【巧解导析】句中all后面的he had为定语从句，此题考查动词短语devote…to的用法．to为介词，排除A，C项．set up schools的动作并未发生，排除D项．

提示：

【巧解点悟】英语中有些动词短语中的“to”为介词，不要误以为它是不定式符号．常见的有：be/get used to, lead to, pay attention to, look forward to(渴望)，stick to(坚持)．
