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”,相当中文中说的“被……”、“由……”的句式,如:“His bicycle was stolen.他的自行车被偷了。”,“The building has been built in 2000.这座楼房是由他们建造的。”二.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. (计算器不能用数学考试。) Books and newspapers in the reading room mustn’t be taken away. (阅览室的书籍和报纸不准带走。) He was awarded first pri was cleaned just now. The station was built in 192 |
