In 1983, there were only 200 computers connected to the Internet; now there arearound 50 million and this growth is clearly going to continue. 解析：本句是由分号连接的两句话，第二句话为and连接的并列句，第一句话中过去分词connected to theInternet做后置定语，修饰computers。翻译：1983年，只有200台计算机联网，现在有大约5000万并且还在持续增长。拓展：过去分词作定语，在语态上，表被动；在时间上，表示动作已经发生或完成。也有用不及物动词的过去分词作定语的情况，一般作前置定语，它不表示被动意义，只表示主动意义，强调动作完成。如：fallen leaves 落叶 ；retired workers 退休工人；the risen sun升起的太阳。2. “In the next few years,” says Angela Rossetto of Cyberia magazine, “it is clear that weare going to see a huge growth in shopping on the Internet. 解析：本句的直接引语中采用了主语从句，it做形式主语，that引导主语从句。这种句型可以表达为：It is +adj.+that 从句。翻译：网络世界杂志的安吉拉罗塞托说：“显然，未来几年中我们会看到网上购物迅猛发展。”拓展：it 做形式主语的句型还有：1. It is+n. +that2. It is+v-ed +that3. She also believes that, in the future, we will get entertainment from the Net and thattelevision will probably disappear. 解析：本句主句为：she also believes.，后接and 连接的两个宾语从句，第二个宾语从句不能省略that。在通常情况下，引导宾语从句的连词that 是可以省略的（通常只含有一个宾语从句）；但是以下三种特殊情况下，that 不能省略。1.that引导的宾语从句置于句首时，that不能省略。2.当that从句被其他词或从句隔开时，that一般不宜省略，以免造成语义混乱。3.当两个或多个that引导的宾语从句并列使用时，即使省略了第一个从句的引导词that，后面的that也不可省略。翻译：她还认为将来我们会再网上进行娱乐活动，而且电视可能会消失。4. Cathy, do you mean well use the computer to travel around the world, entering andexiting countries in seconds and visiting all the historical sites? 解析：本句中主句为：do you mean.，后接宾语从句，从句中现在分词“entering and exiting countries insecondsand visiting all the historical sites” 做伴随状语，与句子主语之间是主动关系。翻译：凯西，你的意思是我们将用电脑环游世界，几秒钟内进出各国，并参观所有的历史名迹？5. We would not only be able to travel around the world, but also go to studyin anyworld famous universities we wanted to go. 解析：本句中not onlybut also连接两个谓语动词，同时we wanted to go为定语从句修饰 any world famousuniversities，省略引导词that。not only. but (also).在句中常用来连接两个对等的成分，also可以省略。翻译：我们不仅能环游世界，还能去任何想去的名校学习。6. But I still find it hard to imagine. 解析：本句中it为形式宾语，真正的宾语为动词不定式，可以总结为句型：find it+adj. + to do sth，意为：发现某事是的。翻译：但是我还是发现很难想象。拓展：it 做形式宾语的句型归纳为：“动词+it+宾语补足语+不定式（动名词或从句）”的结构，动词通常是：think,believe, make, find, consider, feel, take，宾补通常为形容词和名词。如：We think it important to learn a foreign language. 我们认为学外语很重要。 They found it difficult that they would finish their work in two days.他们发现两天完成工作很难。重点语法1. will与be going to的区别：willbe going to表示推测，揣想依据直觉，经验或知识等依据观察到的迹象，证据等表将要临时决定提前计划，安排，打算推测，揣想：I think it will be rainy tomorrow.我认为明天有雨。Look at the clouds; its going to rain.看看这些云，又要下雨了。表示“将要”：1. -“Kate is in hospital.” -“Oh, really, I didnt know. I will go and see her at once.”（临时决定去看Kate）。2. -“Kate is in hospital.” -“Yes, I know. I am going to see her this afternoon.”（提前已打算好去看Kate）拓展：在“主将从现”中，一般用will，而不用be going to。例如：I wont go if he doesnt come.他不来，我就不去。2. if真实条件句和if虚拟条件句 真实条件句：所表示的条件是真实的，或者完全有可能实现的，主从句的谓语都用陈述语气。时态注意使用“主将从现”。例如：If she doesnt hurry up, she will miss the first bus.若果她不快点儿的话，她就错过第一班车了。If it rains tomorrow, I will stay at home.如果明天下雨的话，我就待在家里。虚拟条件句：所表示的条件不可能或很难实现，或与事实相反，主句和从句的谓语要用虚拟语气。同学们需牢记：if从句主句与现在事实相反过去式（be用were）would/ should/ might/ could+动词原形与过去事实相反had + 过去分词would/ should/ might/could+ have done与将来事实相反1. 过去式（be用were）2. were to + 动词原形3. should + 动词 原形would/ should/ might/could+动词原形If I were you, I would not let out the secret.如果我是你的话，我不会泄露这个秘密的。（暗含事实：我不是你）If I knew his new address, I would tell you.如果我知道他的新地址，我会告诉你的。（暗含事实：我不知道他的地址）If she were to/should come/came tomorrow, I would tell her the secret.如果明天她来的话，我会告诉她这个秘密。（暗含事实：她明天不太可能来）If you had taken my advice, you wouldnt have been late for the meeting.如果你听了我的建议，你开会就不会迟到了。（暗含事实：你当时没有听我的建议）Unit 4 Cyberspace单元测试II. 单项选择 15x1 9. - What did you suggest_ , Joan? - I suggested _ her father for his opinion.

There are only about 29 million people there. Most Canadians are of British or French origin, and French is an official language of Canada as well as English. About 45% of the people are of British origin, that is, they or their parents or grandparents, etc, come from Britain. Nearly 30% are of French origin. Most of the French-Canadians live in the province of Quebec.Over the years, people have come to live in Canada from many countries in the world. They are from most European countries and also from China, besides other Asian countries.However, Canada was not an empty country when the Europeans began to arrive. Canadian Indians lived along the coast, by the rivers and lakes and in forests. Today there are only about 350 000 Indians in the whole country, with their own languages. In the far north live the Inuit. There are only 27 000 Canadian-Inuit. Their life is hard in such a difficult climate. 35.About _ live in Quebec.

BAustralia, with the Pacific Ocean to the east and the Indian Ocean to the west, is a very large country, while its population is very small. Another interesting fact is that one out of five Australians was not born in Australia. Most of the population is in the southeast part. Three out of every five people live in five big cities. Sydney is the biggest city with the population of 3 million. Melbourne in Victoria has a population of about 3 million. Brisbane, Adelaide and Perth each has about one million. All of these cities, except Perth, which faces the Indian Ocean, are in the east and southeast of the country.The capital city of Australia, Canberra, is not very big. Only about a quarter of a million live there. Hobart in Tasmania, which is to the south of the main land of Australia, is even smaller and Darwin, the capital of Northern Territory, is a very small city.
