九年级被动语态讲解与练习.doc

（4） 、同步巩固：1.被动语态英语有两种语态：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Cats eat fish. （主动语态）猫吃鱼。Fish is eaten by cats.(被动语态)鱼被猫吃。被动语态的构成由“助动词be 及物动词的过去分词”构成助动词be 有人称、数和时态的变化，其变化规则与be 作为连系动词时完全一样。 一般现在时 Is/am/are +过去分词 English is spoken in many countries.一般过去时 was/were +过去分词 This bridge was built in 1989.情 态动 词 can/should/may /must/+be+过去分词 The work must be done right now.被动语态的用法当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者，或者只需强调动作的承受者时，要用被动语态。2. allow sb. to do sth. 允许某人做某事（主动语态）如：Mother allows me to watch TV every night. 妈妈允许我每晚看电视。be allowed to do sth. 被允许做某事（被动语态）如：LiLy is allowed to go to Qinzhou. 莉莉被允许去钦州。3. get their ears pierced 穿耳洞让/使（别人）做某事 have/get sth. done(过去分词)如：I get my car repaired. = I have my car repaired. 我让别人修好我的车4. enough 足够形容词enough 如：beautiful enough足够漂亮enough名词如：enough food 足够食物enough to 足够去做如：I have enough money to go to Beijing. 我有足够的钱去北京。She is old enough to go to school.她够大去读书了。5. stop doing sth. 停止做某事Please stop speaking.请停止说话。stop to do sth. 停止下来去做某事Please stop to speak. 请停下来说话。6. 看起来好像sb. seem to do sth. = It seems that +从句He seems to feel very sad.It seems that he feels very sad. 他看起来好像很伤心。7.倒装句:由so助动词(be/do/will/have)/情态动词主语意为：也是一样Neither/Nor + be动词/助动词/情态动词+主语(前为否定) 表示与前面所述事实一致.She is a student.
