现在完成时的被动语态
一、结构：have / has been done
二、用法：1）表示到现在为止已经完成的某个被动动作。
The new museum has already been completed(完成)
recently.
2）表示某个被动动作在说话之前发生，但对现在造成影响
Your son has been sent to the hospital, so you needn’t
worry too much.
3）表示过去已经开始，持续到现在，也许还会持续下去的某个被动动作，往往与表示一段时间的状语连用（如for，
since）等，或者so far, now, today, this week 等连用。
Computers have been widely used since the 1970s.
三、副词的位置：often, usually, always, never, hardly, seldom
等副词置于have/ has 与been中间
Such a man has hardly been believed.
四、并不是所有动词都有被动语态。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（发生）, die, appear（出现）, disappear（消失）, remain,
last（持续）, sit , break out（爆发）, come true（实现）, belong
to，consist of，run out(耗尽)等
但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 look after, take care of，take off , look at, send for(请),
