1被动语态的定义,英语动词有语态，一种是主动语态，另一种是被动语态。

主动语态的主语是动作的执行者，相当于语文中的一般句子。

被动语态的主语是动作的承受者，相当于语文中的被动句。

被动语态的基本时态有过去，现在，将来，和完成时。

我们本单元主要学习的是它的一种特殊形式。

它叫做含情态动词的被动语态,2.含情态动词的被动语态,它的构成如下：

动作的承受者+情态动词+助动词be+及物动词的过去分词+by+动作的执行者。

（当我们不知道谁是执行者或没有必要指出时可以省略）Flowersshouldbewateredbyuseveryday.Classroommustbecleaned,3、allow的用法,1.allowsbtodosthMyteachersallowmetodiscusswithmypartnersinclass.2.beallowedtodosth被允许做某事weareallowedtogooutwithourfriendsonweekend.,Grammarfocus,Firstofall,teacheraskssomestudentstotranslatesentencesinChinese.,1.Teenagersshouldnotbeallowedtotakemobilephonestoschool.2.Teenagersshouldbeallowedtodohomeworkwithfriends.3.Teenagersshouldnotbeallowedtogooutatnight.4.Teenagersshouldnotbeallowedtohavepart-timejobs.Lateron,teachersgivesfourminutestoread3aandthenfinishthechart.,Thechartasfollowed:
