(3)在特殊句式hardly/scarcely ...when ...; no sooner ...than ...中，主句常用过去完成时，该句式意为“一……就……；刚……就……”。

—Can I call you back at two o’clock this afternoon?

—I’m sorry, but by then I will be flying to Beijing. How about five?

二、动词的语态

英语中动词有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。

做有关被动语态的题目可以分两步走：第一步确定正确的时态，第二步确定正确的语态。判断用主动语态还是用被动语态的根据是看主语与谓语动词之间的关系：如果是主谓关系则用主动语态，如果是动宾关系则用被动语态。

被动语态的构成(以write为例)

时间 现在 一般时态 am/is/are written 进行时态 am/is/are being written was/were being written 完成时态 has/have been written had been written 过去 was/were written
