情态动词的被动语态例句
情态动词的被动语态例句情态动词的被动语态,听起来是不是有点高深?别担心,今天咱们就来聊聊这个话题,轻松搞定它。
什么是情态动词?简单来说,就是那些表示可能、能力、必要等的动词,比如“can”、“must”、“should”等等。
然后,什么是被动语态?嘿,简单点说,被动语态就是强调动作接受者,而不是动作发出者。
听上去有点儿复杂,但实际上,咱们生活中随处可见这样的用法。
比如说,“The cake can be eaten.” 这句话的意思就是“这个蛋糕可以被吃掉。
” 哇,听着就让人有种饥饿的感觉,是吧?想象一下,一个美味的巧克力蛋糕摆在桌子上,你完全忍不住,心里想着:“这蛋糕肯定要被吃掉。
” 说到这里,我的口水都快流下来了。
还有像“Homework must be finished before dinner.” 听起来就像个家长的声音,对吧?这句话的意思是“作业必须在晚餐前完成。
” 一听到这,很多学生可能都想哭了。
真是的,谁喜欢做作业啊,尤其是在香喷喷的晚餐面前。
再来看看“Loud music should be turned down.” 这句话就是“大声的音乐应该被调小。
” 想象一下,在家聚会的时候,朋友们都在疯狂地摇摆,结果邻居敲门了,满脸不悦,指着你说:“这音乐应该被调小!”哎呀,那场面,真是既尴尬又搞笑。
然后你心里想着:“不就是听个音乐嘛,怎么还惹到邻居了?”这就是生活的奇妙之处。
再说说“Lessons can be learned from mistakes.” 这句子有点深奥,但其实意思就是“错误是可以被吸取教训的。
” 有些时候,咱们都可能在生活中犯错,嘿,别担心,错了就是错了,关键是能不能从中学到点东西。
想想那些经典的失败故事,像爱迪生发明灯泡时试了上千种材料,结果还是给他找到了答案。
生活就是一场实验,学会从失败中站起来,真的是一门重要的艺术。
再来个轻松点的例子,“The dishes need to be washed.” 这句子你肯定听过吧,意思就是“碗碟需要被洗了。

初三英语含情态动词的被动语态常考点
(每日一练)初三英语含情态动词的被动语态常考点单选题1、Teenagers should be allowed______ their own clothes.A.to chooseB.chooseC.choseD.choosing答案:A解析:试题分析:句意:应该允许青少年们们穿他们自己的服装。
动词allow\后接to不定式,故选A。
考点:考查动词不定式。
2、People who drink wine to drive after May Day.A.don’t allowB.isn’t allowedC.mustn’t be allowed答案:C解析:句意:在五一之后喝酒的人不被允许开车。
don't allow不允许;isn't allowed不被允许;mustn't be allowed千万不能被允许。
根据句意可知,这句话的主语People和动词allow构成被动关系,应使用被动语态,排除A。
主语People是集合名词,谓语动词应用复数,故B不对。
C选项是含有情态动词的被动语态形式,符合句意,故选C。
3、People under 18 shouldn’t ________ to Internet Bar.A.allow to goB.allowed to goC.be allowed to goD.be allowed going答案:C解析:句意:18岁以下的人不应该被允许去网吧。
考查被动语态和非谓语。
分析语境可知,主语“People”与谓语“allow”构成被动关系,含情态动词“should”的被动语态形式为should be done,因此空处填be allowed...,排除选项A和B;sb. be allowed后接不定式to do作主语补足语,表示“某人被允许做某事”,所以用be allowed to go。
故选C。

课堂小结
含情态动词的被动语态
被动语态情态动词结构
被动语态情态动词结构1. 被动语态的基本概念被动语态,这玩意儿在英语里可不简单!你知道吗,它让动作的接受者站到了舞台的,而不是动作的执行者。
比如,“这个蛋糕被吃了”,咱们就看到了蛋糕的悲惨命运,而不是谁把它吃了。
这种说法就很符合我们生活中常见的情景。
比如,有时候你会听到朋友们说:“我的手机被盗了。
”听上去有点可怜,对吧?但是呢,使用被动语态可让事情听起来更官方,更严肃,仿佛这事儿大得不能再大了。
1.1 情态动词的角色情态动词在这里也很有意思,像是加了一点调料,让句子变得更加丰富。
你想,假如说“这个蛋糕可能被吃掉了”,那感觉就完全不一样了!它不仅仅是个陈述,仿佛在告诉你,这个蛋糕的命运还不确定,留了一点悬念。
情态动词像是个小帮手,让咱们在描述事情时有了更多选择。
1.2 实际应用场景想象一下,你在学校,老师问你:“这个项目是谁完成的?”如果你用被动语态回答,可能会说:“这个项目被我们完成了。
”哇,这样听起来是不是更有团队精神呢?又或者在工作中,你被要求提交报告,你可能会说:“报告已经被完成了。
”这时候,你的同事听了会觉得你工作效率真高,不是吗?这种方式特别适合在正式场合中使用,毕竟,咱们有时候得让人觉得我们真有能耐!2. 被动语态的趣味被动语态不仅仅是个语法点,它还藏着许多趣味。
你有没有注意到,很多时候我们会用被动语态来避开责任?比如,“这个项目被拖延了”,就让人觉得事情没那么严重,也不指向特定的人。
这种情况下,大家都知道“谁”拖延了,但又好像没人愿意承认,真是个妙招!2.1 日常生活中的被动语态在日常生活中,被动语态的使用可谓是无处不在。
比如,你看到一杯水倒翻了,可能会听到有人说:“水被洒了。
”这时候,水洒的责任似乎不再重要,重要的是解决这个小麻烦。
再比如,有人被邀请去参加聚会,他可能会说:“我被邀请了。
”这话听上去就很高级,似乎他在社交界很有一席之地。
大家会想,这人真不错,连邀请都被他“收到了”。
情态动词的被动语态
