7、le say that tea is good for both health and business!环节说明：将听、说、读、写的任务结合起来不仅锻炼了学生的语言综合运用能力，还巩 固了学生对目标语言的学习、识记和运用。Step4讲解重点短语和句型：a.词汇包：1. produce v.生产，制造;也可做名词，意思是：产品；产量；产额；结 果例句：They produce all kinds of toys in this factory.他们在这个工厂里生 产各种各样的玩具。produce make 和 grow 的用法1. produce可以表示生产汽车、机器通过制造而获得的产品。例句
8、：They produce cars/ planes他们生产汽车、飞机。也可以表示生产粮食蔬菜、通过种植而获得的产品。例句：They produce wheat and rice. 他们生产小麦、稻谷。2. make制造主要指制造工业品；如：make cars/ planes制造汽车、飞机； 不能表示通过种植而获得的产品，不 能说make rice and wheat3. grow种植、栽培；主要指庄稼，农产品；例句They grow wheat and rice every year. 他们每年种小麦、水稻。课堂练习：Many of us knows how to tea, but few
9、knows where tea trees areA. make, made B. grow, grown C. produce, made D. make, grown【解析】根据题意可知，第一空是怎样泡茶 make tea ；第二空是“种茶 树” grow tea trees;故答案选择C。2. made of,由制(构)成。后接构成某物质的原料。例句：This skirt is made of silk.这件裙子是用丝绸制成的。be made of/from/up of 的区别1. be made of表示制成成品后，仍可看出原材料是什么，保留原材料的质和形状, 制作过程仅发生物理变化。
10、例句：The kite is made of paper.风筝是用纸做的。2. be made from表示制成的东西完全失去了原材料的外形或特征，或原材料在制作过 程中发生化学变化，在成品中已无法辨认。例句：The paper is made from wood.纸是木头做的。Butter is made from milk.黄油是从牛奶中提炼出来的。3. be made up of用,，构成或组成的。指人、物皆可，指结构成分例句：Our class is made up of six groups. 我们班是由六个小组组成的。 课堂练习：This dishisn t made meat,
11、its made vegetables.A. of, of B.of, fromC. from,of D.from, from【解析】由句意可知，这首菜不是肉做的，是从外表形状上看要用。f；这首菜是用蔬菜做 的而外上却看不见，要用from.故先C。b.句式包：1. It seems that many people all over the world drink Chinese tea. 好像全世界的许多人都在喝中国茶。句型“It seems that-意为看起来好像/似乎,J ,其中seem是连系动词，意为“似 乎；好像”，句型中的it是形式主语，不能用其他代词来替代。例如：It seem
12、s that he was late for the train. 看来他没赶上火车。seem的几种常见结构1. seem to do sth,此句型可与 “It seems that”转换。例句： They seem to find the way to the cinema. =It seems that they find the way to the cinema.他们似乎找到了去电影院的路了。2. seem+形容词。例句： My temperature seems (to be) all right. 我的体温看上去正常了。3. seem+名词。【例句】That seems not
13、a bad idea. 看上去主意不错。课堂练习：看起来他在考试前一点都不紧张。that he was not a bit nervous before the exams.解析：用“It seems that”结构，再由was确定seem要用过去式。正确答案是 It seemedo2. When the leaves are ready, they are picked by hand and then are sent for processing in factory.当茶叶成熟时，就被用手工采摘然后送到工厂加工。此句是由when引导的时间状语从句，are picked, are sen
14、t都是一般现在时的被动结 构。例句： When the fruit are ready, they are picked and are sent to themark for sale.当这些水果成熟后就被摘下来并送到市场上卖掉。Step5语法：一般现在时态的被动结构及用法一、概念理解：1 .时态：在英语语言中，时态主要讨论行为动词发生的时间。如：He often helps me with my English. 他经常帮助我学英语。（help这个动作 经常发生。ften；故用一般现在时）英语中常用的时态有：一般现在时、一般过去时、一般 将来时、现在进行时、过去进行时、现在完成时、过去完成
15、时、过去将来时等等。2 .语态：在英语语言中，语态主要讨论句子主语与行为动词的关系。语态有两种：主动 语态和被动语态。 主语是动作的发出者（执行者）为主动语态；如：The tall boy often hits his classmates （主语 boy 是谓语动词 hit 的发出 者）。主语是动作的接受者（承受者）为被动语态。汉语中常用“被”、“给由”、“受” 等词用来表示被动，而英语用：助动词be +及物动词的过去分词构成如：Chinese is spoken by the most people in the world （主语 Chinese 是谓 语动词speak的接受者）。2.语
16、态与时态的关系：在任何一个英语句子中都同时存在语态时态，他们是分析一个英语句子的两个主要元素。 如： He is looking after his sister at home.（此句为现在进行时的主 动语态结构）He is being looked after well by his parents.（此句为现在进行时的 被动语态结构）说明：我们以前所学的各种时态的结构其实都时主动语态的各种时态结构。二、被动语态最基本的句型结构是：be +及物动词过去分词说明：、be有时态，人称和数的变化。、被动语态中的谓语动词必须是及物动词；因为被动句中的主语是动作的承受者, 某些短语动词如 look
17、after, think of, take care of, work out, laugh at 等，也可用于被动语态。三、被动语态的使用1 .当不知道或没有必要指出动作的执行者时，常用被动语态，这时往往不用by短语。Mr. White, the cup with mixture was broken after class. ” （只是告 诉老师杯子坏了，不知是谁弄坏的，或不想说出谁弄坏的）。2 .突出或强调动作的承受者，如果需要说出动作的执行者，用by短语。如：The cup was broken by Paul.3 .当汉语句子的主语既不是动作的执行者，也不是动作的承受者时，这时常用i
18、n +名词 作状语，而代替by短语。如：These cars were made in China.四、主动语态变被动语态的变法：主动语态与被动语态之间如何转换1.把主动语态的宾语变成被动语态的主语。2.把主动语态的谓语变成被动语态的be +过去分词，时态要与原句保持一致。3把主动语态的主语变为介词by的宾语，放在被动语态里谓语动词之后，by短语可以 省略。如果原句主语是地点名词，在被动语态中用in +地点名词作状语。口诀：宾变主，主变宾，谓变be done ，时不变，数格必须随被变。五、一般现在时的被动语态：am /is/ are +done如：Tea is grown in Hangzho
19、u. 杭州种植茶叶The roomevery day. You can live in now.A. cleans B. is cleaning C. is cleaned D. has cleaned【解析】根据句意“房间每天都打扫，你现在可以居住了“，可知，房间是每天被打扫，所 以要用一般时态的被动语态，所以选择答案C。课堂练习：将下列句子改为被动语态，并根据情况保留或去掉动作的执行者1. They will say nothing more about this matter.2. They have made some flowers of silk.3. He wrote a poe
20、m.4. The students are planting some trees and flowers.5. They are to open up a new business next week.6. Children couldn t have done all this damage.7. All of us will see him off at the airport.8. They feed the tigers at the zoo three times a day.9. You must hand in your homework before five.10. Peo
21、ple say that she is a good teacher.The keys:1. Nothing more will be said about this matter.2. Some flowers of silk have been made by them.3. A poem was written by him.4. Some trees and flowers are being planted by the students.5. A new business is to be opened up next week.6. All this damage couldn
22、t have been done by children.7. He will be seen off at the airport by all of us.8. The tigers at the zoo are fed three times a day (by them).9. Your homework must be handed in before five (by you).10. It is said that she is a good teacher. (That she is a good teacher is said by them.)Step6作业：复习被动语态的用法。做一些被动语态的练习。八、板书设计：Unit5 What are the shirts made of ?1 . be made of/ be made from/ be made in/be made up of2 ,被动语态的构成：主语+ be + vt ,过去分词+其它。一般现在时态的被动语态：主语+ be ( am / is / are ) +过去分词+。九、教学反思：本节课着重谈论产品由什么制成已经产地，主要就这个话题进行练习。延伸到被动语态的 用法，学生们对被动语态掌握和运用还需提高。
