4、ake English to your heart，进而 take this class to your heart，顺利切入正题聚精会神上好这节课。二、实物导入拿出两把材质不同的尺子，介绍单词 metal、plastic，再利用这两个词的词组导出句型：Whats this ruler made of? Where is it made? Whats it used for? 紧接着按小组 drill 这几个句型，一直到熟练为止。 学习生活中常见物品材质的单词，例如 wood、pr、glass、cotton、nylon、silk、polyester、rubber等等，为下一步的学习扫除单词。三

5、讲解新授英语中及物动词有两种语态，即主动语态和 语态。主动语态表示主语是动作的执行者 语态表示主语是动作的承受者。 语态由“助动词 be+及物动词的过去分词” 。助动词 be 有人称、时态和数的变化。（一）、 语态的用法：一般现在时的语态：is / am / are + 及物动词的过去分词Our classroom is cleaned everyday. I am asked to study hard.Knives are used for cutting things.一般过去时的语态：was / were + 及物动词的过去分词A new shop was built last yea

6、r. Dinosaur eggs were laid long long ago.现在完成时的语态：has / have + been + 及物动词的过去分词This book has been translatedo many languages.Many man-made salites have been sent upo space by many countries.一般将来时的语态：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 ye

7、ar.含有情态动词的语态：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.Yourcan be handedomorrow.6. 现在进行时的语态：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

8、trees over there. Trees are being planted over there by them.7. 不定式的语态：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.（二）、 怎样把主动语态改成语态?把主动语态改为语态非常简单，可以遵循以下几个步骤：1.先找出谓语动词；2.再找出谓语动词后的宾语；3.把宾语用作语态中的主语；4.注意人称、时态和数的变化。（三）、 使用语态应注意的几个问题：1. 不及物动词无语态。What will h

9、appen in 100 years.The dinosaurs disappeared about 65 million years ago.2. 有些动词用主动形式表示意义。This pen writes well.This new book sells well.3. 感官动词或使役动词使用省略 to 的动词不定式，主动语态中不带 to，但变为语态时，须加上 to 。例：make somebody do somethingsomebody+ be +made to do somethingsee somebody do somethingsomebody +be +seen to do

10、somethingA girl saw my wallet drop when she passed by.My wallet was seen to dry a girl when she passedby.Thes made the littoy do heavy work.The littoy was made to do heavy work by thes.4. 如果是接双宾语的动词改为语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。He gave me a book.A book was given to me by him.He showed m

11、e a ticket.A ticket was shown to me by him.My father bought me a new bike. A new bike was bought for me by my father.5. 一些动词短语用于语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。We cant laugh him. He cant be laugh by us.He listens to the radio every day. The radio is listened to by him every day.The nurse is taking ca

12、re of the sick man. Thesick man is being taken care of by the nurse.只要你掌握了以上一些方法，语态并不难学。四、操练阶段运用演示文稿和幻灯片让学生两人一组进行 pair work 问答练习，先练习单数，后练习复数，并且适时提醒学生注意主谓一致。五、设置起伏点视听一段语态的chant，既可以放松心情，也可以调节气氛，还可以在产生愉悦的感受的同时达到复习巩固的目的。六、升华阶段使用课堂展示过的物品、图文，进行连词造句竞赛，男生各一组，在规定时间内造句数多的一组获胜。找一个同学做计数员，教师控制时间和速度。这个过程用时三分钟，设计目的是为口头作文打基础。最后，进行笔头练习巩固。教师精选练习题如下:1. Wheres the cup of?It of china.(make)2. English as thelanguage in Australia.(speak)3. Bikeswidelyby Chipeople. (use)4. This song oftenby the children in class.(sing)5. Vegetableshis shop.(sell)6.T
