知识点一、现在进行时的被动语态
【知识梳理】
现在进行时的被动语态由“be being+及物动词的过去分词”构成, 助动词be有人称和数的变化(am, is are ).
1. 表示此刻正在进行的被动动作。
The project is being discussed at the meeting.
A new film is being shown in the theater.
My house is being painted now.
2. 表示现阶段正在进行的被动动作,但此动作不一定在此时此刻发生。
Many interesting experiences are being carried out these days.
A modern school is being built in our hometown.
A computer center is being built for the students?
3. 表示经常的被动行为,常和always, often, constantly 等词连用。(表达某种感情色彩)
He is always being praised by the teacher.
一. 注意不可遗漏being
现在进行时的被动语态表示说话时正在进行的一个被动的动作,强调主语是动作的承受者,其构成为“am / is / are + being+动词的过去分词”。如果我们把being漏掉,就成为一般现在时的被动语态或系表结构。
如: Look! The children are being taken care of by their aunt. 瞧!那些孩子正由他们的姑妈照看着。
区别:Children are taken good care of at school. 孩子们在学校被照看得很好。(指通常情况)
二. 注意不可忽视 “现阶段”
现在进行时的被动语态也可表示目前这一阶段正在进行的一个被动的动作。
如: Many interesting experiments are being carried out these days.
如今许多有趣的实验正在被进行着。(说话时, 并不一定在进行)
3. 注意没有现在进行时的被动语态的动词
一些表示“状态、心理活动、拥有、存在”等的动词, 一般不用现在进行时的被动语态, 而常用一般现在时的被动语态。如:
Xiao Wang, come here. You are wanted on the phone. 小王, 过来, 有你的电话。
Football is becoming more and more popular. In other words, it is loved by more and more people. 足球现在越来越流行了, 换句话说,它被越来越多的人喜爱。
四. 注意“be +under/ in等介词+名词”结构可表示现在进行时的被动语态的含义。
如:The problem is under
