答案 ：D 通过率 ：41%

16个时态，用16句话，便可以讲解完毕。时态必须在语篇中学习，才能真正掌握。
7 . 此题系2001年之（31）题
A computer can only do ________ you have instructed it to do.
A. how B. after C. what D. when
答案 ：C 通过率 ：74%
测试语言点 ：名词从句，状语从句与动词不定式的协调应用。
要吸取的经验 ：
类似第27题，这个短句子要作为一个“整体”看待。上文的do与下文的do都要兼顾。上文的do, do什么？下文的do又do什么？不回答这两个问题，便会顾头不顾尾，选择失误。试对比下面句子的不同上下文 ：
A computer can only do __what__ you have instructed it to do.
A computer can do nothing __when__ you haven’t instructed it to work .
A computer can only do something __after__ you have instructed it to do so.
A computer does not know __how_ human beings constructed robots ----
its new generation .
8. 此题系2001年之（32）题
Visitors __________ not to touch the exhibits .
A. will request B. request C. are requesting D. are requested
答案 ：D 通过率 ：66%
测试语言点 ：动词被动语态与主动语态的区别。
要吸取的经验 ：
request这个动词你可能不认识，但是只要掌握了动词被动语态与主动语态的句型，顾名思义，便会区别它们 。例句：
Visitors _are requested（are asked） not to touch the exhibits .
Visitors _request _ the guide not to show them around such a large hall with so many
exhibits within such a short time . It is to take them only half an hour to visit
the whole museum !
Visitors _will request_ the tour agency to make up for the loss of their time if there

Visitors _are requesting _ the tour guide not to waste too much time on the exhibits
they are not interested in at all
