How long has the book been borrowed ? 1. 使用现在完成时的被动语态要注意以下几点: 1) 现在完成时的被动语态的两个助动词，即have/has和been，两者缺一不可。

2) 只有及物动词才有被动语态，不及物动词（词组）没有被动语态, 如:happen, take place, die, appear, disappear, fail, remain, lie, last, sit , stand, break out, come true, belong to等．

副词的位置

often, usually, always, never, hardly, seldom等副词置于have/has和been中间。如:

[误] Such a man has been hardly

believed.

[正] Such a man has hardly been

believed. 许多不及物动词加介词或副词构成的短语

动词，相当于及物动词，也可以有被动语态。

但短语动词是一个不可分割的整体，变为被动

语态时，不可丢掉构成短语的介词或副词。如：

e.g. A notice has been put up on the wall. Task4 Consolidation.

用括号内动词或词组的适当形式填空

1．More than 5,000 used bikes__________________ (collect) since the two brothers set up the organisation.
