Question

【题目】When I went into the room, I saw my foreign teacher ____ some students with their oral English.

A.helpingB.to helpC.helpD.having helped

Answer 1

【答案】A

【解析】

考查非谓语动词。句意：当我走进房间时，我看到我的外国老师正在帮助一些学生练习英语口语。短语see sb. doing sth.看见某人正在做某事，此处现在分词doing作宾语补足语，表示正在发生的动作，根据with their oral English可知外教正在帮助学生练习口语。故选A项。
