现在进行时和现在完成时的被动语态
一、现在进行时的被动语态
[观察思考]
①We are being killed for the wool beneath our stomachs.
②Our fur is being used to make sweaters for people like you.
③I wonder what is being done to help you.
④So good things are being done here to save local wildlife.
⑤A project about protecting the natural resources is being designed.
[归纳用法]
(一)形式
肯定式
主语+be(am,is,are)+being+done
否定式
主语+be(am,is,are)+not+being+done
一般疑问式
be(am,is,are)+主语+being+done
特殊疑问式
疑问词+be(am,is,are)+主语+being+done
(二)用法
1.表示此刻正在进行的被动动作。
She is being examined by a doctor.
她正在接受医生的检查。
2.表示现阶段正在进行的被动动作,但此动作在此时此刻不一定发生。
A new station is being built.
一个新的车站正在建设中。
3.表示经常性的被动行为,常与always,constantly 等词连用。
He is always being praised by the teacher.
他总是被老师表扬。
4.与部分情态动词连用,表示对正在发生的动作的推测。
He may be being scolded by his father at the very moment.
此刻他也许正被他父亲责骂。
[注意事项]
1.不及物动词(短语)、非延续性动词、表示存在意义/所属关系/静态特征的动词以及系动词不用于现在进行时的被动语态。
2.一些表示状态、心理活动、拥有、存在等的动词,如have,want,need,like,realize等,一般不用于进行时的被动语态,而常用一般现在时的被动语态表示此时此刻或目前主语正在承受谓语动词表示的动作。
3.“be+in/on/under等+名词”结构可表示现在进行时的被动语态的含义。
