【预习导学】 汉泽英

1)计算机是何时发明的?

2)谁发明了计算机?

典型例题解析: 1.--What a nice classroom! --It ____ every day.

A. is cleaning B. has cleaned C. must clean D. is cleaned

解析:推测这句话的意思应该是“它每天都被打扫”,考查被动语态的结构be + 动词的过去分词。因此答案应该选D。

2.I know Beijing well. I ____ there three times. A .will go B. have been C. went D. have gone

解析:推测这句话的意思“我很了解北京,我去过那三次”。表示去过应该采用的时态是现在完成时,因此可排除A和C,区别have been和have gone,have been 去过;have gone 去了(还没回来)。因此应该选择B。

中考连接:

1.--Look at the sign on the right. --Oh, smoking ____ here.

A .doesn’t allow B. isn’t allowed C. didn’t allow D. wasn’t allowed

2. --Will you come to the dinner party? --I won’t come unless Jim ______.
