Question

6. Mr Wang told us that he would devote all the time he could spend     his oral English before going abroad.

A. improve          B. to improve

C. improving        D. to improving

Answer 1

6.    D考査面定词组和动名词。句意：王先生告诉我们在出国前他会将他能够花的所有的时间来提髙他的英语口语。这里使用了词组devote all the time to doing sth，意为"花费所有的时间做某事"，to是介词，后面接动名词，所以选D。
