　　the internet and telecommunications教案

　　module 6　the internet and telecommunications

　　话题导入

　　电脑网络是我们日常生活中的重要工具,如果没有了它,这个世 界不知会变得如何?电脑网络能处理的事情太多了,衣、食、住、行、吃、喝、玩、乐、电子采购、电子公文交换、电子支付、电子保健、电子监理等等,都和电脑脱不了关系,它还能把事情整理得井井有条。在以后的岁月中,不懂电脑网络的人很可能寸步难行!

　　背景知识

　　the first computer

　　世界上第一台电子数字式计算机于1946年2月15日在美国宾夕法尼亚大学正式投入运 行,它的名称叫eniac(埃尼阿克),是电子数值积分计算机(the electronic numberical integrator and computer)的缩写。它使用了17468个真空电子管,耗电174千瓦,占地170平方米,重达30吨,每秒钟可进行5000次加法运算。虽然它的功能还比不上今天最普通的一台微型计算机,但在当时它已是运算速度的绝对冠军,并且其运算的精确度和准确度也是史无前例的。

　　computer network

　　将地理位置分散的计算机通过专用的电缆或通信线路互相连接,就组成了计算机网络。网络可以使分散的各种资源得到共享,使计算机的实际效用提高了很多。计算机联网不再是可有可无的事,而是计算机应用中一个很重要的部分。人们常说的因特网(internet,也译为国际互联网)就是一个通过通信线路连接、覆盖全球的计算机网络。通过因特网,人们足不出户就可获取大量的信息,与世界各地的亲友快捷通信, 进行网上贸易等等。

The Internet and Telecommunications教案 篇2

　　the internet and telecommunications教案

　　典句精讲

　　1.in 1969,darpa,a us defence organisation, developed a way for all their com puters to“talk”to each other through the telephon e.

　　1969年，一个美国国防部的组织――darpa研发出了一种办法，用电话线路把其所有的计算机连接起来使其相互“对话”。

　　【巧解句构】 该句中for all their computer to“tal k”to each other through  the telephone作way的定语。darpa是advanced research projects a gency的缩写，意指（美国国防部）高级研究计划署。

　　2.it then became possible for universities to use the system as well.

　　就在那个时候，美国的大学也能够使用这种网络系统了。

　　【巧解句构】 as well as与as well同义，但常用来连接两具并列成分，可译为“除……之外；和”。强调第一个成分，连接两个主语时，谓语动词的数和第一个主语一致。如：

　　you as well as i are right.我是对的，你也是对的。

　　3.the world wide web（the web）is a computer network th at allows computer users to access information from millions of websites via the in ternet.

　　万维网是一种计算机网络，它允许计算机用户通过因特网从数百万计的网站上存取信息。

　　【巧解句构】  该句中含有一个that引导的定语从句，先行词为computer network。不定式短语to access information fro m millions of websites via the internet作computer users的宾语补足语。

　　4.at the moment, about 80 percent of web traffic is in english, but this percentage is going down.当时，80%的网络信息是用英文传输的，但这个比率正在下降。

　　【巧解句构】 percentage /百分数；百分率。percentage前不与数字连用，如：不直接说：three percentage，而改为three percent或a percentage of three。of后的名词若为不可数名词，动词为单数；若为复数名词，动词为复数。

　　5.berners-lee built his first computer while he was at university using an old television!读大学时，伯纳斯•李利用一台旧电视机制成了他的第一台电脑。

　　【巧解句构】 本句中分词短语using an old television充当方式状语，修饰主句动词built。

　　6.berners-lee made it possible for everyone to use the internet, not just u niversities and the army.

　　伯纳斯•李使得人人使用因特网成为可能，而不仅仅是大学和军队。

　　【巧解句构】本句中it为形式宾语，for everyone to use the internet为真正的宾语，possible作宾语补足语。如：

　　we found it possible for him to do the task. 我们发现他可能做那工作。

　　7 .talking  on a mobile phone is expensive, so a lot of mobile phone communication are text messages.用移动电话谈话费用很高，所以使用移动电话进行的很多交流都是采用发送文本短讯的方式。

　　【巧解句构】 该句是由so连接的并列句，前一句中动名词短语talking on a mobile phone作主语。so意思是“因此，所以”，为并列连词。therefore亦为“因此，所以”之意，为副词。

　　8.you can make it even cheaper by shortening the words that you use.

　　通过缩短词汇，可使费用更低。

　　【巧解句构】句中by短语充当方式状语，that引导的是定语从句，修饰words。even意为“更”，加强比较级程度。

　　9.you can also avoid using punctuation like inverted commas.还可以避免使用像引号这样的标点符号。

　　【巧解句构】该句中，avoid后接动名词短语作宾语。inverted commas（=quotation mark）为“引号”之意。you意为“人，任何人”，在汉语中往往省略不译。

　　10.he designed t he first“web browser”, which allowed comp uter users to access documents from other computers.

　　他设置了第一个网络浏览器，这可以使电脑运用者得到其他电脑的文件。

　　【巧解句构】 这是一个由which引 导的非限制性定语从句。短语allow sb. to do sth.意思是“允许某人做某事”

　　拓展延伸 注意此处空半格比较as, which引导的非限制性定语从句：两者都可引导定语从句，但在句子意思和在句中的位置上有所差异：as有时含有“如同”的意思，而which则不具备这个意思。as引导的定语从句，可以放在句首、句中或者句末，而which引导 的定语从句则不能放到句首。
