I want to change (的式样)_the shoes.4. What are they _？（用来做）5.They_ （被发明）Julie.III.自学质疑： 仔细观察例句的意思，分析句子的结构和含义。 一 被动语态的定义，概念。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。例如：Many people speak English.谓语：speak的动作是由主语_来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。巧记为：被动、被动、主被动。例如：English is spoken by many people.主语_是动词speak的承受者。主动态和被动态指的是动词形式，是词法概念；而主动句和被动句则指的是句子结构，是句法概念。所谓主动句就是由主动态动词(词组)作谓语动词的句子，而被动句则是由被动态动词(词组)作谓语动词的句子。例如：He opened the door.他开了门。(_句)The door was opened.门被开了。(_句)二、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。人称、数和时态的变化是通过be的变化表现出来的。现以teach为例说明被动语态在各种时态中的构成。一般现在时：amisaretaught 一般过去时：_taught一般将来时：willshall betaught现在进行时：amisare beingtaught 过去进行时：_taught现在完成时：havehas beentaugh 过去完成时：_taugh三、被动语态的用法(1)不知道或没有必要说明动作的执行者是谁。例如：Some new computers were stolen last night. 一些新电脑在昨晚被盗了。(不知道电脑是谁偷的) (2)强调动作的承受者，而不强调动作的执行者。例如：the window was broken by Mike.窗户是迈克打破的。歌诀：谁做不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。四、主动语态变被动语态的方法被动语态中动作的发出者或执行者做介词by的宾语，放在句末，by 表示“由，被”的意思如： Many people speak English.主动语态： 主语+ 谓语动词 + 宾语 + 其他成分 被动语态： 主语+ be +过去分词 + by +宾语 +其他成分 English is spoken by many people.歌诀是：宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。五、含有情态动词的被动语态含有情态动词的主动句变成被动句时，由“情态动词be过去分词”构成，含有make,let,have,see,watch,hear,feel,notice等役使动词或感官动词变成被动语态后“to”仍要补出来。口诀是：情态动词变被动，情态加be加“过分”，原来带to要保留。例如：思考1.We can repair this watch in two days. 2. I saw him go into the room.This _ in two days. He was seen_ into the room.六、即时练习1. The bridge _ by the farmers themselves in 1982.A. built B. was builtC. buildD. was build 2.

Please _ me one hour _finsh the work.(给时间去做)III合作探究探究一：单词More，更多的, many/much -more most多于多音节单词和部分单音节单词连用。more important/most important(多音节单词) useful- more usefulmost useful(单音节单词)与表示数量的词连用时，要放在后面。同义词another(与表示数量的词连用时，要放前面)例如：a few more minutes 又有几分钟 Six more books= another six books 又有六本书思考：I need _ _/ _ _ minutes to finsh the work.（再多十分钟）探究二：短语、句型1、What do you think is the most helpful invention? 分析do you think 可以看作是插入语，用“疑问词+do you think+正常语序”的结构。例：What do you think he would do next? 你认为他接下来将做什么？思考：你认为谁是我们国家最好的篮球选手。Who _ _ _is the best basketball player in our country. 2、It gives people more time to work and play every day. 它(电灯)每天给人们更多的时间去工作和娱乐。分析动词不定式短语to work and play every day在句中作目的状语。 注意give sb. some time to do sth给某人一些时间去干某事思考：Joining WTO_ Chinese people more chances _work.加入WTO给了中国人更多找到工作的机会。3、Yes，but thats not going to help you leave the island. 是的，但那也将无助于你离开那个岛。分析1该句中用了help sb. (to)do sth“帮助某人干某事这个词组，动词help后由动词不定式担当宾语补足语，可以带to，也可以不带to。思考：He _ _ _ English every day. 他天天帮我学英语。注意 在这些使役动词和感官动词变为被动语态时，则应该把原来省略的动词不定式符号to加上。例：The child is made to go to bed before nine oclock in the evening by his parents父母迫使那个孩子九点以前上床睡觉。思考：Lucy was _ sing a song last night. 昨天晚上有人听见露茜唱了一首歌。IV 测评提升 （1）补全对话a.
