3.现在完成进行时:现在完成进行时是现在完成时和现在进行时的组合,表示从过去某时开始一直持续到现在并且还要继续下去的动作或表示到目前为止的一段时间里一直反复进行的动作,它既具备现在完成时的特征,又具备现在进行时的特征,如:它具备进行体的“未完性、暂时性、感情色彩”的特点。
Unit 2 Lessons in life被动语态被动语态的基本用法:不知道或没有必要指明动作的执行者是谁时用被动语态;需要强调或突出动作的承受者或事件本身时也常用被动语态(by短语有时可以省略)。
[观察例句]1.My washing machine is being repaired this week,so I have to wash my clothes by hand.2.I was sent to the village last month to see how the development plan had been carried out in the past two years.3.When fat and salt are removed from food,the food tastes as if it is missing something.4.The students have been working hard on their lessons and their efforts will be rewarded with success in the end.5.Steam engines were used to pull the carriages and it must have been fairly unpleasant for the passengers,with all the smoke and noise.[归纳用法]一、被动语态的构成:be +过去分词各种时态的被动语态形式(以do 为例)1.主动变为被动时,宾语成了主语,(作补语的)不定式前需加to(位置不变)。
