電腦網(wǎng)絡(luò)是我們?nèi)粘I钪械闹匾ぞ?如果沒(méi)有了它,這個(gè)世 界不知會(huì)變得如何?電腦網(wǎng)絡(luò)能處理的事情太多了,衣、食、住、行、吃、喝、玩、樂(lè)、電子采購(gòu)、電子公文交換、電子支付、電子保健、電子監(jiān)理等等,都和電腦脫不了關(guān)系,它還能把事情整理得井井有條。在以后的歲月中,不懂電腦網(wǎng)絡(luò)的人很可能寸步難行!
背景知識(shí)
the first computer
世界上第一臺(tái)電子數(shù)字式計(jì)算機(jī)于1946年2月15日在美國(guó)賓夕法尼亞大學(xué)正式投入運(yùn) 行,它的名稱叫eniac(埃尼阿克),是電子數(shù)值積分計(jì)算機(jī)(the electronic numberical integrator and computer)的縮寫。它使用了17468個(gè)真空電子管,耗電174千瓦,占地170平方米,重達(dá)30噸,每秒鐘可進(jìn)行5000次加法運(yùn)算。雖然它的功能還比不上今天最普通的一臺(tái)微型計(jì)算機(jī),但在當(dāng)時(shí)它已是運(yùn)算速度的絕對(duì)冠軍,并且其運(yùn)算的精確度和準(zhǔn)確度也是史無(wú)前例的。
computer network
將地理位置分散的計(jì)算機(jī)通過(guò)專用的電纜或通信線路互相連接,就組成了計(jì)算機(jī)網(wǎng)絡(luò)。網(wǎng)絡(luò)可以使分散的各種資源得到共享,使計(jì)算機(jī)的實(shí)際效用提高了很多。計(jì)算機(jī)聯(lián)網(wǎng)不再是可有可無(wú)的事,而是計(jì)算機(jī)應(yīng)用中一個(gè)很重要的部分。人們常說(shuō)的因特網(wǎng)(internet,也譯為國(guó)際互聯(lián)網(wǎng))就是一個(gè)通過(guò)通信線路連接、覆蓋全球的計(jì)算機(jī)網(wǎng)絡(luò)。通過(guò)因特網(wǎng),人們足不出戶就可獲取大量的信息,與世界各地的親友快捷通信, 進(jìn)行網(wǎng)上貿(mào)易等等。

the internet and telecommunications教案
典句精講
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,一個(gè)美國(guó)國(guó)防部的組織——darpa研發(fā)出了一種辦法,用電話線路把其所有的計(jì)算機(jī)連接起來(lái)使其相互“對(duì)話”。
【巧解句構(gòu)】 該句中for all their computer to“tal k”to each other through the telephone作way的定語(yǔ)。darpa是advanced research projects a gency的縮寫,意指(美國(guó)國(guó)防部)高級(jí)研究計(jì)劃署。
2.it then became possible for universities to use the system as well.
就在那個(gè)時(shí)候,美國(guó)的大學(xué)也能夠使用這種網(wǎng)絡(luò)系統(tǒng)了。
【巧解句構(gòu)】 as well as與as well同義,但常用來(lái)連接兩具并列成分,可譯為“除……之外;和”。強(qiáng)調(diào)第一個(gè)成分,連接兩個(gè)主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞的數(shù)和第一個(gè)主語(yǔ)一致。如:
you as well as i are right.我是對(duì)的,你也是對(duì)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.
萬(wàn)維網(wǎng)是一種計(jì)算機(jī)網(wǎng)絡(luò),它允許計(jì)算機(jī)用戶通過(guò)因特網(wǎng)從數(shù)百萬(wàn)計(jì)的網(wǎng)站上存取信息。
【巧解句構(gòu)】 該句中含有一個(gè)that引導(dǎo)的定語(yǔ)從句,先行詞為computer network。不定式短語(yǔ)to access information fro m millions of websites via the internet作computer users的賓語(yǔ)補(bǔ)足語(yǔ)。
4.at the moment, about 80 percent of web traffic is in english, but this percentage is going down.當(dāng)時(shí),80%的網(wǎng)絡(luò)信息是用英文傳輸?shù)模@個(gè)比率正在下降。
【巧解句構(gòu)】 percentage \百分?jǐn)?shù);百分率。percentage前不與數(shù)字連用,如:不直接說(shuō):three percentage,而改為three percent或a percentage of three。of后的名詞若為不可數(shù)名詞,動(dòng)詞為單數(shù);若為復(fù)數(shù)名詞,動(dòng)詞為復(fù)數(shù)。
5.berners-lee built his first computer while he was at university using an old television!讀大學(xué)時(shí),伯納斯•李利用一臺(tái)舊電視機(jī)制成了他的第一臺(tái)電腦。
【巧解句構(gòu)】 本句中分詞短語(yǔ)using an old television充當(dāng)方式狀語(yǔ),修飾主句動(dòng)詞built。
6.berners-lee made it possible for everyone to use the internet, not just u niversities and the army.
伯納斯•李使得人人使用因特網(wǎng)成為可能,而不僅僅是大學(xué)和軍隊(duì)。
【巧解句構(gòu)】本句中it為形式賓語(yǔ),for everyone to use the internet為真正的賓語(yǔ),possible作賓語(yǔ)補(bǔ)足語(yǔ)。如:
we found it possible for him to do the task. 我們發(fā)現(xiàn)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.用移動(dòng)電話談話費(fèi)用很高,所以使用移動(dòng)電話進(jìn)行的很多交流都是采用發(fā)送文本短訊的方式。
【巧解句構(gòu)】 該句是由so連接的并列句,前一句中動(dòng)名詞短語(yǔ)talking on a mobile phone作主語(yǔ)。so意思是“因此,所以”,為并列連詞。therefore亦為“因此,所以”之意,為副詞。
8.you can make it even cheaper by shortening the words that you use.
通過(guò)縮短詞匯,可使費(fèi)用更低。
【巧解句構(gòu)】句中by短語(yǔ)充當(dāng)方式狀語(yǔ),that引導(dǎo)的是定語(yǔ)從句,修飾words。even意為“更”,加強(qiáng)比較級(jí)程度。
9.you can also avoid using punctuation like inverted commas.還可以避免使用像引號(hào)這樣的標(biāo)點(diǎn)符號(hào)。
【巧解句構(gòu)】該句中,avoid后接動(dòng)名詞短語(yǔ)作賓語(yǔ)。inverted commas(=quotation mark)為“引號(hào)”之意。you意為“人,任何人”,在漢語(yǔ)中往往省略不譯。
10.he designed t he first“web browser”, which allowed comp uter users to access documents from other computers.
他設(shè)置了第一個(gè)網(wǎng)絡(luò)瀏覽器,這可以使電腦運(yùn)用者得到其他電腦的文件。
【巧解句構(gòu)】 這是一個(gè)由which引 導(dǎo)的非限制性定語(yǔ)從句。短語(yǔ)allow sb. to do sth.意思是“允許某人做某事”
拓展延伸 注意此處空半格比較as, which引導(dǎo)的非限制性定語(yǔ)從句:兩者都可引導(dǎo)定語(yǔ)從句,但在句子意思和在句中的位置上有所差異:as有時(shí)含有“如同”的意思,而which則不具備這個(gè)意思。as引導(dǎo)的定語(yǔ)從句,可以放在句首、句中或者句末,而which引導(dǎo) 的定語(yǔ)從句則不能放到句首。
