Question

—Betty, do you know if Tony ______ the photo competition?
—He will, if he ______ his project on Australia.

A．enters; finishes	B．enters; will finish
C．will enter; finishes	D．will enter; will finish

Answer 1

C

前者问“贝蒂，你知道托尼是否要参加摄影比赛？”这里的if引导的是宾语从句，翻译为是否，前者问的是将来；后者答的话是由if引导的条件状语从句，所以遵循主将从现的原则，所以if之后用一般现在时。所以答案选C。
