人教版新目标英语九年级第九单元

第九单元重点是被动语态,只要你把被动语态弄会了就好了。语态是动词的一种形式,用以说明主语与谓语动词之间的关系。英语的语态共有两种：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。被动语态是动词的一种特殊形式,一般说来,只有需要动作对象的及物动词才有被动语态。被动语态可以概括为“be done”。也就是“be+过去分词”。一般现在时、一般过去时用be +及物动词的。过去分词,be有人称、时、数变。完成时态have（has）done,被动将been加中间。一般将来shall（will）do,被动变do为done。将来进行无被动,shall（will）be doing。现在完成进行时态,have（has）been done。现、过进行be doing,被动be加being done。否定助后加not,疑问一助置主前。主语恰是疑问词,直陈语序主在前。一般情助加be done。主动语态变为被动语态例句：一般现在时：主：We believe him。被：He is believed by us。一般过去时：主：He bought his children some pens。被：Some pens were bought for his children by him。一般将来时：主：Everyone will know the truth soon 。被：The truth will be known by everyone。现在进行时：主：Mary is making a doll。被：A doll is being made by Mary。过去进行时：主：They were carrying the hurt player。被：The hurt player was being carried by them 。现在完成时：主：He has received the letter。被：The letter has been received by him。过去完成时：主：They had built ten bridges。被：Ten bridges had been built by them。一般现在或过去时用be done,be有人称、时态和数的变化。例：1、主动：The children gave the foreign guests a warm welcome。被动：The foreign guests were given a warm welcome by the children。孩子们热烈地欢迎外宾。2、主动：People regard him as brilliant。被动：He is regarded as brilliant by people。人们认为他很有才华。一般用法1。一般现在时的被动语态构成：is / am / are +及物动词的过去分词Our classroom is cleaned everyday。I am asked to study hard by my mother。Knives are used for cutting things。2。一般过去时的被动语态构成：was / were + 及物动词的过去分词The new shop was built last year。Dinosaur eggs were laid long long ago。3。现在完成时的被动语态构成：has / have + been +及物动词的过去分词This book has been translated into many languages。Many man-made satellites have been sent up into space by many countries。4。一般将来时的被动语态构成：will+ be + 及物动词的过去分词A new hospital will be built in our city。Many more trees will be planted next year。5。含有情态动词的被动语态构成：情态动词+ be + 及物动词的过去分词Young trees must be watered often。Your mistakes should be corrected right now。The door may be locked inside。Your homework can be handed in tomorrow。6。现在进行时的被动语态构成：am / is / are + being +及物动词的过去分词Uncle Wang is mending my bike now。→My bike is being repaired by Tom now。They are planting trees over there。→Trees are being planted over there by them。7。不定式的被动语态：to + be + 及物动词的过去分词There are two books to be read。→There are twenty more trees to be planted。我是从百度百科被动语态里面给你筛选的一些重要的知识点。 再问： 被动啥的都会啦、、、 学了好多年了捏。 想要的是单词的讲解 再答： 哎呀！早说啊！ invention inventor发明者 be used for doing salt-salty fall into - fell into pleasant pleasure please in a way 在某种程度上 throw-threw-thrown abacuses复数 activity creative divide into shoot at developed rise-rose-risen 剩下的我没提到的你就自己背吧。 抓紧采纳！！！以上纯属手打！！！
