英语被动语态一、什么是被动语态? 英语中时态很多,但语态不多,只有两种,即:主动语态和被动语态。所谓“被动语态”,相当于中文中常说的“被……”、“由……”的句式,如:“他的自行车被偷了。”,“这座楼房是由他们建造的。” 二、被动语态的结构那么,英语中被动语态是怎么样构成的呢?请看下面的例句His bicycle was stolen. The building has been built in 2000. 通过上面的例句,可以看出,“被动语态”的构成是: be + 过去分词+ (by+动作执行者三、被动语态的运用什么情况下要用被动语态呢?一般地说,有下面几种情况:
(1不知道谁是动作的执行者或没有必要。例如: Paper is made from wood. (纸是由木材生产出来的。The house is quite old. It was built in 1950. (这座房子太旧了。它是1950年建成的。He was wounded in the fight. (他在战斗在受伤了。Electricity is used to run machines. (电是用来开动机器的。(2需要强调动作的对象时。例如: Calculator can't be used in the maths exam. (计算器不能用于数学考试。Books and newspapers in the reading room mustnt be taken away. (阅览室的书籍和报纸不准带走。He was awarded first prize in that contest. (他在比赛中获得了第一。
