答案
1. C 将来完成时态。 By 指：到什么时间为止。
2. D 将来完成时态。 tomorrow 表示将来， get the instructions （指令，指示）这个动作在我回来之前已经完成。
3. B “no sooner……than……”( 刚 …… 就 ……) ，在 no sooner 这部分应当用过去完成时， than 后面用一般过去时。 A ， B 都是过去完成时态，怎么选择？ No sooner 的特殊用法，在其后面跟倒装语序，所以选 B 。
4.Ｂ　 hardly……when……( 一 …… 就 ……) ， hardly 后应当用过去完成时， when 后面用一般过去时。 hardly 的特殊用法，在其后面跟倒装语序，所以选 B 。
5. A 过去将来时态。 Forgive 原谅， She’d 相当于： she would. 妈妈不知道我看电视花费了多长时间，如果她知道的话，我相信她将永远不会原谅我。
6. D 过去完成时态。 发现错误这个动作发生在纠正数据那个动作之前，而改正数据的动作用的是过去时态，所以，发生在过去的过去的动作就用过去完成时态。 error 错误。 correction 改正，是名词。 data 数据。
7. B 现在完成时态。表示渴望见你这个动作从过去一直延续到现在以至于将来。 look forward to 渴望，想要 …… 。 ever since 自从 …… 。
8. B 现在完成进行时态。通过上下句来识别时态。

12. C 我已经好几个月没有 Maria 的消息了。现在完成时态， for 引导一个时间状语。
13. C 现在完成时态。他的祖父已经去世三十年了。这里死亡表示一种状态，而不能理解为一种动作，因为死亡是一个短暂性动词，它不可能持续三十年。所以用 has been dead 。
14. A It’s(high)time （是 …… 什么的时候了）的特殊用法，要用完成时态。 Have 在句中是拥有的意思。
15.C　将来完成时态。 Leave for 离开一个地方到另一个地方去， By the time 　信号词。
16.D　将来完成时态。 by the end of 　到 …… 时间为止，在此句中引导的时间状语从句为将来时间，所以是用将来时。答案 B ， D 选取哪个？机器（ machines ）是被修的，所以用被动语态。显然， D 为正确答案。
17. B 译文：会议从开始到结束，将持续整整一个星期。本句是将来完成时的用法。到将来某时(会议结束)之前业已完成的动作(last) ，所以用将来完成时。
