【題目】I don’t know if he______. If he _____ tomorrow, I’ll call you.

A. will come; comes B. comes; will come

C. will come; will come D. comes; comes

【答案】A

【解析】句意:我不知道他明天是否來,如果他明天來,我就打電話告訴你。第一句是if引導(dǎo)的賓語從句,根據(jù)tomorrow可知是將來時態(tài),will do sth;第二句是if引導(dǎo)的條件狀語從句,不用將來時態(tài),用一般現(xiàn)在時態(tài)來代替,主語是he,謂語動詞用單數(shù)形式;故選A
