1、Unit 7,Text A,Before Reading,Reading,After Reading,Vocabulary Practice,Enjoy English,Before Reading,Discuss the following questions in class.,What kind of information do you usually get from the Internet? 2. What would happen to our daily lives if all computers stopped working for one hour?,In 1949,

2、 a group of scientists were testing an early computer in a laboratory in the United States. It was a huge machine, built by experts for thousands of dollars. But it would not work. One of the scientists opened the front of the computer and went in to investigate. He came out with a large insect whic

3、h had become trapped in the machine. From that day on, any fault that stops a computer from working properly has been known as a “bug”.,Chinese,Reading,Can You Speak Technology in a Wired World?,2. The original bug is still preserved in a glass case. The word has now passed into the English language

4、 along with thousands of others from the world of computing. It is sometimes called “tech-speak”, a large vocabulary of words invented in laboratories and now used across the English speaking world by everyone who switches on a computer. 3. “Tech-speak” probably started in California, the place wher

5、e most of the early work on computing was done. Perhaps the fact that we “surf” the Internet is evidence of a California connection. Here are a few more examples of “tech-speak”.,Chinese,Reading,4. With personal computers now widespread, there is increasing concern about the activities of “hackers”,

6、 who break into computing systems. Hackers are also responsible for the spread of “viruses”, software programs which alter the way in which computers work. Viruses are commonly spread through document files attached to e-mails. Increased use of the Internet has also introduced innovations of computi

7、ng language. When people speak face to face, they often use facial expressions to help convey meanings. This cannot be done by e-mails. Instead, people sometimes use “emoticons”. After making a statement, they will add : - ) to show that something makes them happy. And when people who mainly communi

8、cate by e-mail meet in person, they agree to spend “face time” together.,Chinese,Reading,The last few decades has seen communications companies bring more technology into our everyday lives. So it is no surprise that technological language has become an increasingly important part of English. From b

9、eing the vocabulary used by computer experts, the language of technology has moved to become an important part of real life.,Chinese,Reading,Para. 1,在网络化世界里你会讲技术术语吗? 1. 1949 年，在美国的一个实验室里，一群科学家正调试一台早 期的计算机。这是一台专家们花费了成千上万美元制造的巨大机器，但它却无法运转。其中一名科学家打开这台计算机的前盖，走进去查看。从那里他找出一只被卡在计算机里的虫(bug)。从那天起，任何一个使计算机无法正

10、常运转的故障都被称为“bug”。,译 文,Reading,Para. 23,原先的那只虫仍被存放在一个玻璃盒中。现在“bug”这个词已随同计算机领域的数以千计的其他词汇一起汇入了英语语言中。它们有时被称为“技术词汇”，即大量产生于实验室里的词汇。目前在英语国家中，这些词汇被每个电脑操作者使用着。 3. “技术词汇”可能始于加州，大多数计算机早期研究工作都是在那里进行的。也许在因特网上“冲浪”这一说法可以证明“技术词汇”与加州的联系。这里再举几个有关“技术词汇”的例子。,译 文,Reading,Para. 45,4. 现在，随着个人电脑的普及，“黑客”的活动日益受到关注。黑客不仅随意闯入计算机系

11、统，还对计算机病毒的传播负有主要责任。计算机病毒是改变计算机工作方式的软件程序，它们通常通过电子邮件的附件传播。 5. 因特网的日益普及同样也促成了计算机语言的革新。人们面对面交谈时经常借助面部表情传递信息，而用电子邮件交流时却做不到。有时候人们使用“表情符号”取而代之。在打出一个句子后，他们会加一个“: -)”来表示他们对某事感到高兴。而当一些主要通过电子邮件进行交流的人们见面时，他们乐意一起度过“面对面交流的时光”。,译 文,Reading,Para. 6,6. 近几十年来，通讯公司已经给我们的日常生活注入了更多的科技含量。因此，技术语言已成为英语中越来越重要的内容是不足为奇的。技术语言已

12、经不再是只被计算机专家使用的词汇，它们逐渐成为人们现实生活的一个重要组成部分。,译 文,Reading,From that day on, any fault that stops a computer from working properly has been known as a “bug”. 从那天起，任何一个使电脑无法正常运转的毛病都被称为“虫子”。,Reading,stop . from doing something 意为“阻止做某事”，相当于prevent/keep . from doing something。 如： Her sudden arrival stopped hi

13、m from going out. 她的突然到来使他不能外出。,It is sometimes called “tech-speak”, a large vocabulary of words invented in laboratories and now used across the English speaking world by everyone who switches on a computer.它有时候被称作“技术用语”，即一大批产生于实验室的词语，现在已被讲英语国家中所有用电脑的人广泛使用。,Reading,这是一个长句。从a large vocabulary 一直到句尾都

14、是 “tech-speak” 的同位语，补充说明什么是“tech-speak”，在同位语中又包含分别由invented 和used 引导的定语短语，以及由who 引导的定语从句。,With personal computers now widespread, there is increasing concern about the activities of “hackers” 现在随着个人电脑的普及，“电脑黑客”的行为日益受到关注,Reading,with personal computers now widespread 是一个复合结构，由“介词 with + 名词 + 形容词” 构成，

15、表示伴随状况或原因。 如：I went out with the window open. 我外出时窗户开着。 再如：Dont speak with your mouth full. 吃东西时别说话。,Hackers are also responsible for the spread of “viruses”, 电脑黑客也对“病毒”的传播负责，,Reading,be responsible for 意为“对负责”。 如：We are responsible for our own actions. 我们对自己的行动负责。,Reading,After making a statement,

16、they will add :-) to show that something makes them happy.在写完一句话后，他们会加上一个:-)（笑脸）来表示某事让他们感到高兴。,after 后的短语making a statement 相当于一个时间状语从句after they make a statement, 此时由于从句与主句的主语一致，为避免重复，从句中就省略主语，这样整个句子就显得较为简洁。 如：After making a closing speech, he came back to his seat and sat down. 致完闭幕词后，他回到座位上坐了下来。,A
