从历年考题来看，时态方面约有16道题；语态方面有2道题。时态方面以考查过去完成时和将来完成时居多，兼有其他时态。如：
1. Until then, his family_____from him for six months.
A. didn’t hear          B. hasn’t been hearing
C. hasn’t heard         D. hadn’t heard
    答案为D。全句意为：“到那时为止，他家里已经6个月没有收到他的来信了。”句中谓语动词的动作延续到过去某一时刻（until then）才完成，因此要用过去完成时。
2. My train arrives in New York at eight o’clock tonight. The plane I would like to take from there ___by then.
A. would leave  B. will have left   
C. has left     D. had left
    答案为B。全句意为：“我乘坐的火车要到今晚8点到达纽约，到时我转乘的飞机已经飞走了”。本题句中空格后时间状语by then实际上指的是by eight o’clock tonight。所以该句应选用将来完成时态，表示在将来某一时刻之前已经完成的动作。
3. The conference______a full week by the time it ends.
A. must have lasted        B. will have lasted
C. would last              D. has lasted
    答案为B。全句意为：“会义从开始到结束将持续整整一个星期”。句中by the time it ends 表示动作延续到将来某一时刻，因此要用将来完成时。
