English by many people in China.2.Bell invented the telephone in 1876. The telephone by Bell in 1876.3.We must look afer the old man. The old man after (by us).4.We will clean the city park tomorrow. The city park tomorrow.特殊情况：（含有双宾语的句子变被动语态）剖析：含双宾语的主动语态的句子变为被动语态时，常把那个指人的间接宾语变为被动语态的主语；也可把那个指物的直接宾语用作主语，但此时必须在间接宾语前加上介词 to或for。如：He gave me a book.I was given a book by him.（人作主语）A book was given to me by him. （物作主语）My father bought me a bike.(变被动语态)-。（主语是人）-。（主语是物）口诀：如遇双宾语，一般变间宾。若把直宾变，to,for间宾连。感官动词和使役动词在主动句中其后的动词不定式不带to，但变被动句时必须加上to。如：The boss made her work for 16 hours a day. She was made to work for 16 hours a day. 口诀：感/使动词真叫怪，to来to去记心怀，主动语态to离去，被动语态to回来。 Step2:精读（一）再听精读（二）探究质疑1.annoying inventions 烦人的发明。Annoying做_词，意为_ e.g我认为闹钟是一种烦人的发明，I think the alarm clock is _ _ _ .Annoyed也做形容词，意为烦恼的，生气的。其主语通常是人，常用的短语；be annoyed with sb.意为生某人的气,be annoyed about sth.因某事而生气。E.g老师对那个顽皮的男孩很生气，The teacher _ _ _that naughty boy .(三） 互动解惑 课堂小结：回顾本节课，学到了什么，还有什么疑问？ Step3:拓展（一）汇报点拨（教师寄语：相信自己，你是最棒的！）（二）内化训练（一）、选择填空( )1.The children _ by the nurse.

Take the sentence “How do you do?” for example. If you look up each word in the dictionary, one at a time, what is your translation? It must be a wrong sentence in your own language.Languages dont just have different sounds, they are different in many ways. Its important to master the rules for word order in the study of English, too. If the speakers put words in a wrong order , the listener cant understand the speakers sentence easily. Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes. But sometimes the order is changed, the meaning of the sentence doesnt change between the two pairs of sentences:“She only likes apples.” “Only she likes apples.”“I have seen the film already.” “I have already seen the film.”When you are learning English, you must do your best to get the spirit of the language and use it as the English speaker does.( )1.From the passage we know that when we are learning English.A. we shouldnt put every word into our languageB. we should look up every word it the dictionaryC. we need to put every word into our own language( )2.We can learn from the passage that .A. if the order of words is different, the meaning of the sentence must be differentB. the order of words can never change the meaning of an English sentenceC. sometimes different order of words has a different meaning( )3. “She only likes apples.” .A. is the same as “Only she likes apples.”B. is different from “Only she likes apples.”C. means “She likes fruit except apples.”( )4.
