被动语态教案 【教学目标】1. 要求学生掌握被动语态在六种时态中的用法。2. 使学生能熟练运用情态动词的被动语态。3. 要求学生掌握“get+过去分词 ”结构的用法。【重点难点】1. 被动语态在六种时态中的用法。2. 情态动词的被动语态。【知识铺垫】考点一: 有关被动语态的基础知识  1. 被动语态概述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。如：He opened the door.他打开了这扇门。(主动语态)The door was opened.这扇门被打开了。(被动语态)2被动语态的构成被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的形式，过去分词部分不变。疑问式和否定式的变化也如此。3. 被动语态的用法在被动语态中，主语是动作的承受者，主要用于下列几种情况：(1)不知道动作的执行者是谁。如：This watch is made in China.这块手表是中国制造的。(2)没有必要指出动作的执行者是谁。如：More trees must be planted every year. 每年都应该种更多的树。(3)强调或突出动作的承受者时。如： Chinese is spoken by more and more people in the world.世界上越来越多的人说汉语。(强调汉语的使用广泛)(4)句子的主语是动作的承受者。如：Many houses were pulled down by the earthquake.许多房屋被地震摧毁了。【拓展知识点】 1.不及物动词及连系动词不能用于被动语态。常见词有：happen，take place，look，sound，feel，smell，taste，become等。如: The story happened on a cold night.这个故事发生在一个寒冷的夜晚。The food tasted delicious.这种食物尝起来很美味。2. 在主动语态中省“to”的动词不定式，在被动语态中要加“to”。常见的有感官动词see，hear，watch，feel，notice等，及使役动词let，make，have。如： He made the girl stay at home.(变为被动语态)The girl was made to stay at home.考点二: 一般现在时的被动语态（主语+am/is/are+done）Russian is also taught in their school.他们学校也教俄语。(肯定句)The windows of our house are cleaned once a week我们房子的窗户一星期擦一次。(肯定句)The windows of our house arent cleaned once a week(否定句，在is, am, are后加not)Are the windows of our house cleaned once a week?(一般疑问句，把is, am, are提句首)考点三: 一般过去时的被动语态（主语+was/were+done）Beijing was liberated in January，1949.北京是一九四九年一月解放的。(肯定句)These photos were taken on the Great Wall.这些照片是在长城拍摄的。(肯定句)These photos werent taken on the Great Wall.(否定句，在was, were后加not)Were these photos taken on the Great Wall? (一般疑问句，把was, were提句首)考点四: 一般将来时的被动语态(will+be+done；am/is/are going to+be+done)A new school library will be built next year.一个学校的新图书馆将明年建成。(肯定句)A new school library wont be built next year.(否定句，在will后加not)Will a new school library be built next year?(一般疑问句，把will提句首)A new school library is going to be built next year.一个学校的新图书馆将明年建成。(肯定句)A new school library isnt going to be built next year.(否定句，在isamare后加not)Is a new school library going to be built next year?(一般疑问句，把isamare提句首)考点五: 一般现在时带情态动词的的被动语态(情态动词+be+done)(1)肯定句式（主语+情态动词+be原形+过去分词）The computer must be repaired now.电脑必须立刻修。Many trees should be planted on the mountains.应该在山上种许多树。(2)否定句式（主语+情态动词+not+be原形+过去分词）It can not be done by Peter.这件事不可能是彼得干的。Waste paper should not be thrown on the road.废纸不应该扔在路上。(3)一般疑问句式（情态动词+主语+be原形+过去分词）Must the trees be watered now?这些树必须现在浇水吗？(4)特殊疑问句式特殊疑问词(不作主语)+情态动词+主语+be原形+过去分词When can my computer be repaired?我的电脑什么时候能修好？特殊疑问词(作主语)+情态动词+be原形+过去分词What must be done next?下一步该做什么？【品味中考】( B ) 1.Why does the earth look blue in space?Because most of the earths surface _ by water.
