4)Doyouthinkwemaybeallowedtotakephotosifwedon*tuseaflash?

以上四句都含有重要后句型beallowedtodosth.,其中第三句是此句型的一般

?在时，一二四句是情态动词与此句型的混合使用。

运用："sb.+should/shouldnot+beallowedtodo…”

翻译：

我认为应该允许16岁的孩子开车。

我不同意，我认为16岁这个年纪太年轻了。

你认为应该允许13岁的孩子们做兼职工作吗？

安娜可以选择自己的衣服。

那个年龄的他们不够稳重。

“一个16岁青少年”的表达方式

akidofsixteen

akidofsixteenyearsold

asixteen-year-oldkid

2)Hedoesn'tseemtohavemanyfriends.

主+seemtodosth.好像

e.g.Histemperatureseemstobeallright.他的体温好像完全正常。

seem的其施用法：

II.含有情态动词的被动语态

♦温故♦

在英语中，动词有两种语态，即主动语态和被动语态。主动语态表示主语是

动作的执行者，被动语态表示主语是动作的承受者。在前面两个单元我们已经学

习了一般现在时的被动语态和一般过去时的被动语态，它们的结构为：are/is+

及物动词的过去分词,were/was+及物动词的过去分词。

♦知新♦

本单元我们主要了解含有情态动词的被动语态。它的结构是什么呢？观察下面

例句中含情态动词被动语态的各种形式，然后补全结论中所缺的内容。

【例句】

1.Manytreesshouldbeplantedinthemountains.

应该在山上种许多树。

2.Youcantakethisbookhome.(改为被动语态)

—♦Thisbookcanbetakenhome(byyou).

3.Thisproblemcan'tbeworkedoutveryeasily.这道题轻易算不出来。

4.Musttheworkbedoneatonce?这项工作必须立即完成吗？

【结论】

A.含有情态动词的被动语态的结构为：情态动词+_+及物动词的o

B.含有情态动词的主动语态变为被动语态时，要把主动语态的变成被动语

态的主语。

C.变为否定句时只需要在情态动词后加O

D.变为一般疑问句时只需把提到句首。

【运用】

I.选择最佳答案。

()Youngtreesshouldeveryyear.

A.beplantedB.plantedC.plant

II.按要求完成下列各句，每空一词(含缩写)。

1.Wemustdotheworkrightnow.(改为被动语态)

________________rightnow.

2.Teenagersshouldbeallowedtogooutwiththeirfriendsonschoolnights.(改为
