文档简介

【本讲教育信息】
一. 教学内容:
Unit 4 of Module Ⅱ Cyberspace Period Three Lesson 3 & 4

二. 教学目标与要求:
1、理解和掌握Lesson 3, Lesson 4, Communication Workshop and CultureCorner 中一些长句和疑难句结构和意义。
2、对相关的句式结构和语言现象进行适当的拓展和延伸。

三. 重点句式分析与拓展:
Lesson 3 Virtual reality
1. If I don’t finish my project on the history of the Internet for next Monday’s lesson, the science teacher will be angry.
如果我不为下星期一的课写好一个关于因特网历史的功课,科学老师将会很生气。
解析:
If I don’t finish my project on the history of the Internet for next Monday’s lesson 是一个条件状语从句,on the history of the Internet是一个介词短语,修饰名词project.
拓展:由if, unless, as long as (如果,万一),if only (只要),provided that (假如)引导的条件状语从句或由when, as soon as 等引导的时间状语从句,常用一般现在时表示一般将来时。如:I will go if you go.如果你去,我也去。
I will let you have the money as soon as you finish the work.
你一做完这件事,我就把钱给你。
2. … if we had virtual reality holidays, we wouldn’t have any problems with the weather.
如果我们有虚拟假日,天气就不会有任何影响了。
解析:
这是虚拟语气在条件从句中的应用,表示与现在事实相反,条件句谓语动词用过去式had,主句用would+原形动词have。
3. What’s more, we wouldn’t have to spend a long time travelling on plans to get to our holiday destinations.
另外,我们不必坐长时间的飞机去度假目的地。
解析:
we wouldn’t have to … 是虚拟语气,是承接if we had virtual holiday 而言的。
要点剖析 spend 常用的句型是:
(1)spend +时间(in)doing sth. 花时间做……
She spent two hours doing her homework。她花了两个小时做作业。
(2)spend 时间(金钱)on sth.(sb.)在……上花时间(金钱)
You have spent too much money on your clothes.
你在衣服方面花了太多的钱。
4. We would not only be able to travel around the world, but also go to study in any world famous universities we wanted to.
我们不仅能周游世界,而且能到我们所想要去的任何一所世界名牌大学学习。
解析:
not only …but also 是一个并列连词,所连接的两部分必须一致,连接动词时,动词的时态、语态须一致。如:
We should not only be brave, but also be careful.
我们不仅要大胆,而且要仔细。
not only … but also …连接并列的主语时,主谓一致运用近主语原则。如:
Not only the door but also the windows are open.(连接并列主语)
不仅门开着,窗户也开着。
5. …if they invented virtual reality holidays, I ‘d go on an around –the –world tour.
如果发明了虚拟假日,我就去作环球旅行。
解析:
这是虚拟语气在条件句中的应用,表示与现在事实相反的假设,I’d=I would 。
要点剖析 around –the –world 是一个复合形容词,须用连字符号连接,含有数词时,其后的名词不可加“s”,如:twelve –year-old, ten –metre –long。

Lesson 4 Virtual Tourism
1. It has a population of just under a million people and is located on North Island.
奥克兰人口接近一百万,位于北岛。
解析:
这是一个简单句,主语是It, has 和is located作并列谓语。
重点剖析 population 是指人口的总数,注意“人口多”用“The population is big”。且谓语动词用单数。如:
The population of China is bigger than that of India.
中国人口比印度多。
2. It is also the most exciting city in New Zealand with people of many different cultures living there.
它(奥克兰)是新西兰最激动人心的城市,居住着许多不同文化背景的人。
解析:
with people of many different cultures living there是一个由with 引导的复合结构,构成形式是:with+名词+现在分词,表示方式或背景。
拓展延伸 with 引起的复合结构还有:
(1)with +名词+副词
They left the house, with all the lights on.
他们把所有的灯都开着,离开了房子。
(2)with +名词+介词短语
The boy headed home, with his school bag on his back.
那男孩背着书包回家了。
(3)with +名词+过去分词
With everybody else gone, he really felt alone.
大家都走了以后,他真地感到孤独。
(4)with +名词+现在分词
They arrived at the village at dark, with the boy leading the way.
由这个男孩子带路,他们天黑时到达了村庄。
3. Auckland was the capital of New Zealand for some time. Later, the capital moved to Wellington, because it was more central.
有一段时间奥克兰曾是新西兰的首都,后来搬迁到了惠灵顿,因为惠灵顿更接近中央区。
解析:
because it was more central 是一个原因状语从句,说明谓语动词moved 的原因,more central 是相对于Auckland 而言的,故用了比较级。
辨析比较 some time, sometime 和sometimes
some time 表示一段时间;sometime 是指过去或将来的某一时刻;sometimes 是指时间频率,意为“有时”。
记忆要诀 巧记some time, sometime和sometimes
分写表一段时间,some time
合写表“某时”,sometime 后加“s”表“有时”,sometimes

Culture Corner New Zealand Fact File
1. New Zealand, in the South Pacific, consists of two large islands plus other smaller islands with an area of 270000 sq km.
位于南太平洋的新西兰由两个大的岛屿和一些小岛组成,面积27万平方千米。
解析:
in the South Pacific 是一个介词短语作定语,修饰New Zealand, plus 是介词,意为“加上”。
辨析比较 consist of, make up
consist of 的主语通常表示整体,指一个整体由几个部分组成,make up 的主语通常表示部分,指几个部分构成一个整体。make up 后接of 用于被动语态,consist of 用于主动语态。如:
The United States of America consists of fifty states.
Fifty states make up the United States of America.
The United States in made up of fifty states.美国由50个州组成。
2. Over 80%of the 3.6 million people are of European (mainly British)origin.
三千六百万人口中百分之八十以上的人是欧洲人(主要是英国人)的后裔。
巧解句构 介词短语of the 3.6million people 修饰80%,origin 是名词,意为“起源,由来”
要点剖析 “分数/百分数+of +名词”作主语时,谓语动词的数取决于of 后的名词的单复数。如:
There fifths of the land in this district is covered with trees and grass.
这个地区的五分之三的土地覆盖着树和草。
3. Around 9% of the population are Maoris who came to New Zealand from other Pacific islands in the thirteenth and fourteenth centuries.
大约9%的人口是毛利族,他们是在13和14世纪从太平洋群岛搬迁过来的。
解析:
who came to New Zealand from other Pacific islands in the thirteenth and fourteenth centuries 是一个定语从句,修饰Maoris, 关系代词who 指代Maoris 。
辨析比较 around 和round
round 能作形容词、副词、介词、名词和动词,分别表示“圆的”“转过来”“围着”“圆”和“转动”。
around 只能作副词和介词。作副词时,around 表示“四周、周围”。如:look around 四处看看。round 表示“朝另一方向”。如:turn the car round 使车调头。
作介词时,around 表示“向各处,向……周围”。如:travel around the world 环球旅行。
round 表示“环绕一周”。如:
The moon moves round the earth.月亮围绕地球转。
around 还有“大约”的意思,与about同义。
4. New Zealanders, who are also known as “Kiwis ”,are relaxed people who love outdoor life.
新西兰人,也以“Kiwis”而著称,是一个热爱户外活动、善于放松身心的民族。
解析:
此句有两个定语从句,who are also known as “Kiwis”修饰New Zealanders, who love outdoor life 修饰people, relaxed是一个形容词化了的过去分词,常用来修饰人。
5. It is not surprising that New Zealand is successful at many sports.
新西兰人在许多体育项目上获得成功不足为奇。
解析:
that New Zealand is successful at many sports 是主语从句,其位置由形式主语it 所代替。
拓展:it 的用法:
(1)表示时间、天气、距离、温度、情况等。如:
It ‘s Sunday today.今天是星期天。
What time is it It’s two o’clock.几点了?两点钟。
It’s quite hot during the summer in Beijing.在北京,夏天很热。
It’s about ten kilometers from here to the station.
从这儿到车站大约10千米。
How is it with your friends today 今天你和朋友过得怎样?
(2)代替无生命的东西。如:
He bought a new book. It interested him very much.
他买了一本新书,它令他着迷。
(3)作形式主语或形式宾语。如:
I found it hard to understand you.我感到非常难于理解你。
It is not difficult for her to finish this job in two days.
两天内完成这些工作,对她来说没问题。
(4)用于强调句中;It is +被强调的部分+that /who …如:
It is my teacher who will come.是我的老师要来。
It was on Sunday that I went to the park.我是星期天去的公园。
(5)在强调until 引出的时间状语时,其句型为:It is not until...that...一般多译成汉语的肯定句。如:It was not until 1972 that we began studying English.
直到1972年我们才开始学习英语。
(6)强调句型的一般疑问句为:Is it...that... 强调“when, where, who, what ”等时,须将这类特殊疑问词放在句首。如:
  When was it that the story took place 那个故事发生在什么时候?
  What is it that you have to sell 你要卖的是什么?
辨析比较:
(1)强调句型的连词只可用that /who.
(2)另外两个与此相似的结构,但不属于强调句:It is +时间+since +过去时(如果前面用was,后面可用过去完成时)
  It is +时间+before (根据情景选时态)  如:
  It is ten years since he worked in this university.

Finders, Keepers
I worked for a short time as a casher (出纳员)at a restaurant a few months ago. I also helped clear off the tables when it was especially busy. One night, just before Christmas, I found a large black wallet on the floor near one of the tables. I guess I should have checked it to find out who was the owner, but I was busy at the time. Also, I imagined that if the wallet contained anything valuable, the owner would be back. Sure enough, an hour later a man came up to the counter(柜台)and asked if anyone had found a wallet, I asked him to describe the lost wallet, and after he described it exactly, I gave him the wallet. He expressed his thanks to me when I handed it to him. He asked me if I had opened it, and when I told him “No”, he opened it right away and showed that it contained nearly $800 in cash (现金). I gasped (叹息)as he took out a twenty-dollar bill and handed it to me. “A reward for your honesty,” he said and then turned and walked away.
Thinking about it later, I began wondering whether I would have been so honest if I had known what was in the wallet! I think that if there had been no Way to find the owner and no one had returned to claim (认领)it, I might have kept it. But it also came into my mind that I had in fact saved someone’s Christmas plans by finding and returning the wallet. The good feeling it gave me was worth more than anything.

三. 综合阅读
1. D
考查推理能力,第二自然段倒数第二句说:我(通过把钱包还给失主)挽救了一个人的圣诞节计划,根据西方国家的习俗,圣诞节前一周为购物周,所以判断时间为a couple of days before December 25.
2. C
A.不对,因为我忙得一直没来得及打开钱包。.B. I began wondering whether I would have been so honest if I had known what was in the wallet!本句表达的意思是:要是我原先知道里面有这么多钱,我怀疑我是否会如此诚实!既表达了作者知道钱包里有这么多钱后的惊讶,又说明了作者内心的矛盾和挣扎。D. 说失主极其惊讶,在本文中没有提及。
3. B
因为作者是一个诚实的人,尽管它有遗憾、思想斗争,但是最终作者作出了诚实的选择。
4. A
“Finders keepers, losers weepers”是一句谚语:“谁捡到,就归谁,谁丢了,就倒霉”,看来这句话在作者身上的体现并非如此。
5. D
作者把钱包还给失主后,不是快乐,而是有惊讶、有遗憾、有思想斗争,一直到最终的心灵解脱。
