Unit4 Wildlife protection-语法篇
__________________________________________________________________________________ __________________________________________________________________________________
通过本节课的学习掌握现在进行时的被动语态的用法。
现在进行时的被动语态 一、现在进行时的被动语态的构成：be＋being＋done。如：The new building is being built now; I can’t stand its noise.
新的大楼现在正在被建造，我受不了它的噪声。 二、现在进行时的被动语态的形式
1. 肯定式：主语＋be＋being＋及物动词的过去分词＋其他．如： Another bridge is being built over the Yangtze River. 长江上正在修建另一座大桥。
2. 否定式：主语＋be＋not＋being＋及物动词的过去分词＋其他．如：
Even though your application is not being checked now, the manager will take it into consideration soon. 即使你的申请现在不被审查，但是经理会很快考虑它的。
3. 一般疑问式：Be＋主语＋being＋及物动词的过去分词＋其他？如： Is the life of pandas being studied by the scientists? 科学家们正在研究熊猫的生活习惯吗？
4. 特殊疑问式：特殊疑问词＋be＋主语＋being＋及物动词的过去分词＋其他？如： Where is the new science lab being built? 新的实验室正在哪里建造？ 三、现在进行时的被动语态的用法
1．表示此时此刻正在进行的被动的动作。如： The baby is being taken good care of.
1
婴儿正在被悉心照料着。
2．表示现阶段正在进行的被动的动作。如：
The environment here is being polluted so badly that all the people can't stand it.这儿的环境被污染得如此严重以至于所有的人都感到难以忍受。 3．表示反复进行的被动的动作。
always，frequently，constantly等和现在进行时的被动语态连用表示反复进行的被动的动作，这种动词形式常用来表示赞扬或厌恶的感情色彩。如：
I feel very surprised that the window of our classroom is frequently being broken. 我感到很吃惊的是我们教室的那扇窗户经常被打破。 使用现在进行时的被动语态要注意的五个问题：
1.不可漏掉being，若漏掉，则成为一般现在时的被动语态。
2.可与部分情态动词连用， 表示对正在发生的事情的推测。 He be being scolded by his father. 3.有时可表示按计划或安排要进行的一个被动动作。Some rock music is being played by them next. 4.某些表示“状态、心理活动、存在”等的动词，如have, want, need, love,一般不用现在里时的被动语态，而常用一般现在时的被动语态。
Computer games are loved by more and more young people. 5. “be+under/in…+n.” 可表示现在进行时的被动意义。 常用的这种结构有：
be under attack＝be being attacked 正在被攻击 be under consideration＝be being considered 正在被考虑 be under construction＝be being constructed 正在被建设 be under discussion＝be being discussed 正在被讨论 be under protection＝be being protected 正在被保护 be under repair＝be being repaired 正在被修理
