Question

【题目】With such a tight schedule, everyone will have to go all out if they _____________ the task.

A. have completed B. would complete

C. will complete D. are to complete

Answer 1

【答案】D

【解析】

考查时态。句意：时间安排如此紧张，如果他们要完成这个任务，每个人都要全力以赴。在条件状语从句里应该使用一般现在时代替将来时，所以if条件状语从句中使用be to do sth。故D项正确。
