Question

The boy stopped ___TV and went to do his homework when his mother came back.
A. watch                   B. watching         C. to watch

Answer 1

B

试题分析：此题重点考查两个短语stop to do sth和stop doing sth的区别，前者表示停下来去做某事，后者表示停止做某事。根据语境可知此句的含义是当妈妈回来以后，这个小男孩不再看电视然后去做作业，故选B。
点评：stop后面可以跟动词不定式或动名词做其宾语，这要根据语境的含义来区分到底用to do sth还是doing sth。因此正确理解语境的含义是做此类题目的关键。
