　　（5）被动语态与系表结构的区别

　　被动语态强调动作；系表结构表主语的特点或状态。如：

　　The book was sold by a certain bookstore.(被动语态)

　　The book is well sold.(系表结构)

　　动词的语态一般不单独考，而是和时态、语气和非谓语动词一起考，只是需要注意以下考点。

　　考点一：不能用于被动语态的动词和词组

　　come true, consist of, take place, happen, become, rise, occur, belong, break out, appear, arrive, die, fall, last, exist, fail, succeed

　　It took place before liberation.

　　考点二：下列动词的主动语态表示被动意义, 而且常与well, quite, easily, badly等副词连用。

　　lock ( 锁 ) ; wash ( 洗 ); sell ( 卖 ); read ( 读 ); wear ( 穿 ); blame (责备)；ride (乘坐)； write ( 写 )；

　　Glass breaks easily. 玻璃容易破碎。

　　The car rides smoothly. 这车走起来很稳。

　　The case locks easily. 这箱子很好锁。

　　The book sells well. 这本书很畅销。

　　考点三：一些常用经典被动句型：

　　It is said..., It is reported..., It is widely believed...， It is expected..., It is estimated...,这些句子一般翻译为"据说......"，"人们认为......"，而 "以前人们认为......" 则应该说：It was believed..., It was thought...
