Consolidation and Extension.
完成一个任务
A some students to read about an invention using an encyclopedia or other book from the library, or by looking up information on the Internet. Have the students write up a short report and draw a simple picture of the invention or bring in a photo of it. Ask each students to show the picture and read his or her report to the class.
5. 梳理知识:本单元主要学习了一般过去时的被动语态,包括其结构与用法。利用几项发明创造练习这一知识,最后用一篇小报告来完成写作练习。
6.达标测试:
(一)根据时间和人物写出发明物。
1) 1885____________ 2) 1876 ________________ 3) 1927____________
4) 1976 ________________5) Julie Thompson _________6) Chelsea Lanmon ______
(二)汉泽英
1)计算机是何时发明的?
2)谁发明了计算机?
3)计算机是用来做什么?
4)你认为什么是最有用的发明?
5)它能够给人们更多时间工作和玩。
典型例题解析: 1.--What a nice classroom! --It ____ every day.
A. is cleaning B. has cleaned C. must clean D. is cleaned
解析:推测这句话的意思应该是“它每天都被打扫”,考查被动语态的结构be + 动词的过去分词。因此答案应该选D。
2.I know Beijing well. I ____ there three times.
A .will go B. have been C. went D. have gone
解析:推测这句话的意思“我很了解北京,我去过那三次”。表示去过应该采用的时态是现在完成时,因此可排除A和C,区别have been和have gone,have been 去过;have gone 去了(还没回来)。因此应该选择B。
中考连接:
1.--Look at the sign on the right. --Oh, smoking ____ here.
A .doesn’t allow B. isn’t allowed C. didn’t allow D. wasn’t allowed
2. --Will you come to the dinner party? --I won’t come unless Jim ______.

新目标Unit9 When was it invented?教学设计
Unit9Whenwasitinvented?学案一、学习目标：掌握一般现在时、一般过去时和含有情态动词的被动语态的用法。二、语法介绍：英语中动词的语态分成两种：主动语态和被动语态。当句子的主语是动作的执行者时，谓语的形式叫主动语态；当句子的主语是动作的承受者时，谓语要用被动语态。㈠含义：动词的被动语态一般译成“被…”，但是根据汉语表达习惯，有时“被”也可以不译出。㈡构成：被动语态一般的构成形式为:be+动词过去分词（+by+动作的发出者）。其中助动词be有人称、数和时态的变化。一般现在时:am/is/are+done(过去分词)一般过去时：was/were+done(过去分词)含有情态动词的：情态动词+be+done(过去分词)㈢方法：1、将主动语态句中的宾语变为被动语态句中的主语，主动语态句中的主语变为被动语态句中介词by的宾语。2、将主动语态句中谓语动词变成:助动词be+该动词的过去分词，但时态不改变。3、助动词be要与新的主语保持单、复数一致；若主语和宾语是人称代词时，“格”应作相应的变化。口诀：宾变主，主变宾，谓变bedone时不变，数格必须随着变。Theworkersmakemachinesinthisfactory.!--?xml:namespaceprefix=vns="urn:schemas-microsoft-com:vml"/--
Machinesaremadebytheworkersinthisfactory.注意：不及物动词没有被动语态。㈣例句：1.ManypeoplespeakEnglishin!--?xml:namespaceprefix=st1ns="urn:schemas-microsoft-com:office:smarttags"/--China.EnglishisspokenbymanypeopleinChina.2.Bellinventedthetelephonein1876.ThetelephonewasinventedbyBellin1876.3.Wemustlookafertheoldman.Theoldmanmustbelookedafter(byus).㈤特殊情况：⑴（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：Hegavemeabook.→Iwasgivenabookbyhim.→Abookwasgiventomebyhim.口诀：如遇双宾语，一般变间宾。若把直宾变，to,for间宾连。⑵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：Thebossmadeherworkfor16hoursaday.→Shewasmadetoworkfor16hoursaday.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。三、对应练习：㈠选择填空1.Thechildren____bythenurse.
A.werelookedB.lookedafterC.werelookedafterD.looked2.Thelab____aboutfiveyearsago.
A.wasbuildedB.wasbuiltC.buildsD.hasbeenbuilt3.Theglass______.It_____bylittleTomthismorning.

教材分析及教学要求
重点1.了解古今中外的一些发明创造的英文名字
在本单元，我们将搭乘“科技之光”，了解古今中外的一些发明创造的故事。我们中国有着悠久的历史，博大的文化，更有许多影响人类进程的里程碑式的发明创造。说起四大发明，想必大家都不陌生吧？那么，你知道它们的英文名字吗？
好了，让我来告诉大家。
对了，从左到右，从上往下，分别是火药（gunpowder），指南针(compass)，造纸术(papermaking)，印刷术(printing)。
认识了它们的英文表达后，是不是学起历史来更加有兴致了？是不是更加热爱我们的祖国了？没错！每个发明创造的背后都有许许多多有趣、辛苦的故事。大家可以通过上网、看书，查到许多这方面的资料，从而丰富我们的视野。

computer,TV,car,hand-heldcalculator,camera,shoeswithadjustableheels,umbrella,telephone,flyingdisk,heatedicecreamscoop,lightbulb,hamburgers,radio,microwaveoven,potatochips,pizza,vacuumcleaner,tea,abacus,binoculars,bicycle,batteryoperatedslippers,alarmclock,

重点2.被动语态
什么是被动语态呢？请先看下面两个例子：
Iopenthedoor.我打开门。
Thedoorisopenedbyme.门被我打开。
哦！原来表示某物被某人怎么样的时候，我们可以用被动语态来表示。那么，被动语态是怎么构成的呢？
某物+be动词+动词的过去分词+by+某人
1．把主动态变成被动态的方法是把动词tobe变成原来的主动态动词的时态，再加上主动态里动词的过去分词。
主动态：Bellinventedtelephones.贝尔发明了电话机。
在这个主动态句子中，时态是一般过去时，所以，变成被动态时，首先要把tobe变成它的一般过去时形式，即：was/were。然后加上主动态里的动词的过去分词形式。于是就变成了：
TelephoneswereinventedbyBell.电话机被贝尔发明了。
注意进行时态的被动态。这种语态有时似乎难以使用，因为它要求用tobe的现在进行时，这种形式在其他方面用得不多。
主动态：Theyarerepairingthebridge.
他们正在修桥。
被动态：Thebridgeisbeingrepairedbythem.
桥正在被他们修理。
2．主、被动时态对照表：
时态/动词形式
主动态
被动态
一般现在时
keeps
iskept
现在进行时
iskeeping
isbeingkept
一般过去时

3.本单元出现的被动语态
Whowasit/weretheyinventedby?
它（它们）是由谁发明的？
Itwas/Theywereinventedby…+sb.
它（它们）是由……发明的。
Whenwasit/weretheyinventedby?

1.__________________________?(When)
2.__________________________?(When)
