1．Planning so far ahead ________ no sense—so many things will have changed by next year.
A. made B. is making
C. makes D. has made
[解析]句意：这么早做计划没有什么意义——到明年很多事情就会变了。一般现在时指经常发生的事或存在的状态，由译文可知本句表达目前的状况，符合一般现在时的概念，故答案为C项。
[答案]C
2． 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
[解析]句意：我不敢确定他是真感兴趣还是仅仅是客套一下。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”，也不表示“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。
[答案]A
