Question

【题目】I wasn’t sure if he was really interested or if he polite.

A. was just being B. will just be

C. had just been D. would just be

Answer 1

【答案】A

【解析】考查动词时态。句意：我不敢确定他是真的感兴趣还是仅仅是在表示一下礼貌。本题考查时态。由前文I wasn’t sure if he was…及并列连词or来判断，此处应为过去时，故排除B项；本句并不表示“过去的过去”，也不表达“过去的将来”，故排除C、D两项；本句表示暂时的情况，故用过去进行时态。
