Question

【题目】— Henry is really a great grandfather.

— Sure, he is. He spends all his free time his grandson everything helpful.

A. learning B. teaching C. to learn D. to teach

Answer 1

【答案】B

【解析】

句意：--Henry真的是一个很伟大的父亲。 --是的，他用他所有的空闲时间来教他儿子一切有用的东西。从上文说“他是一个很伟大的爸爸”可知他用一切空闲时间来“教”他的儿子，故排除A,C。另外spend…(in) doing sth, 故选B。
