课上内容(Lesson)
What 什么是语态? 语态是动词的一种形式,用以说明主语与谓语动词之间的关系。
英语的语态共有两种:主动语态和被动语态。
Why 为什么要用被动语态?
1. 突出重点想表达的事
2. 用于强调
3. 责任外国人的思维逻辑,国外的逻辑更常用语被动句
PS: 时态/语态 并无直接关系,只是恰巧他们都有过去分词。
How 如何使用被动语态?了解被动语态之前你先要知道什么是主动语态。
e.g.
Somebody built this house in 1981.(active) 有人在1981年建造了这座房子。 # 但是,实际我们在聊天的时候不一定都清楚是谁、什么原因、通常不知道或者不重要
subject object
This house was built in 1981. (passive) 这座房子建于1981年。 # 所以,这个时候用被动句会感觉说的话更有意义,而不会像(active)一样还去关注subject
subject

e.g.
Some body cleans this room every day.
