一般现在时态的被动语态
概念理解
1. 时态：在英语语言中，时态主要讨论行为动词发生的时间。
　　英语中常用的时态有：一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时、过去将来时等。
语态：在英语语言中，语态主要讨论句子主语与行为动词的关系。语态有两种：主动语态和被动语态。
　　① 主语是动作的发出者(执行者)为主动语态。
如：The most people in the world speak Chinese.
（主语people是谓语动词speak的发出者）。
② 主语是动作的接受者（承受者）为被动语态。
如： Chinese is spoken by the most people in the world.
（主语Chinese是谓语动词speak的接受者）。
③主动语态和被动语态的相互转换。
My grandmother waters flowers every day.
主语 谓语 宾语 其他
Flowers are watered (by my grandmother) every day
例： Today Chinese _______ by more and more people around the world.
A.is spoken B.speak C.speaks
3. 语态与时态的关系：在一个英语句子中都同时存在时态和语态，一般现在时和被动语态，即一般现在时的被动语态。
如：Trees are planted by us every year.我们每年都植树。
