Question

【题目】—I don't remember the teacher's telephone number.

—If you______，we can call her for help.

A. are B. will C. do D. did

Answer 1

【答案】C

【解析】

句意“-我记不住老师的电话号码了。-如果你记得住，我们就能打电话向她寻求帮助”。本题考查“主将从现”原则，if引导的条件句用一般现在时，排除B和D。if引导的条件句可还原为if you remember the teacher's telephone number,包含实意动词，省略时用do，do代指上文提到的记得老师的电话号码一事，故选C。
