被动语态补充说明
(1) 如宾语补语是不带to的不定式，当句子变成被动以后，该不定式由需还原to.
例如：The director made his staff work overtime.
The staff were made to work overtime.
(2) 少数短语动词be taken in, be supposed to do sth, be intended for sth/sb通常只有被动式，
(3) 有一类诸如wash, open, polish, wear, write, sell, pull, push, lock, clean, cut, peel, spoil, read的动词，后接副词时通常用其主动形式表示被动意义。例如：This pen writes smoothly.
(4) 分清表语结构和被动语态。
