Question

【题目】If you have difficult questions, please ________ your teacher for help.

A.turn overB.turn onC.turn to

Answer 1

【答案】C

【解析】

句意：如果你有问题，请向你老师寻求帮助。

考查动词短语。turn over翻转；turn on打开；turn to求助于。分析句子内容可知，此句是条件状语从句，根据“If you have difficult questions,”空后“your teacher for help.”可知，应该使用turn to sb for help，表示向某人寻求帮助；故答案为turn to，故选C。
