1. —It’s a long time since I saw my sister.
— _________ her this weekend?
A. Why not visit B. Why not to visit C. Why not visiting D. Why don’t visit
【解析】答案选A。Why not…为英语中常用句式，用于提出建议，其后只接动词原形，不接不定式或现在分词。注意不能选D，但是若D改为Why don’t you visit也可以选。
2. If you are planning to spend your money having fun this week, better _________ it—you’ve got some big bills coming.

2. _________ many times, but he still didn’t understand it.
A. Having been told B. Though he was told
C. To have been told D. He was told
【解析】答案选D。句中的并列连词 but 表明整个句子为并列句，同时表明but前应是一个独立的句子，而不能是一个非谓语动词短语(所以不能选A或C)，又因为though为从属连词，用以引导让步状语从句，它与连接并列句的并列连词 but 不“兼容”，所以也不能选B。
