Question

【题目】The girl is so helpful that she devoted all her spare time she had ______ others．

A.helpingB.to helpingC.to helpD.helped

Answer 1

【答案】B

【解析】

句意：这个女孩非常乐于助人，她把所有的业余时间都用来帮助别人。

考查非谓语动词。helping帮助，现在分词；to helping帮助，介词短语；to help帮助，动词不定式；helped帮助，过去式。she had在这里做time的后置定语，短语devote … to doing sth. 意为“致力于、献身于做某事”；根据题意，故选B。
