E-mail is one of the biggest threats(威脅)to your home computer．By understanding how E-mail works, and by taking some steps in how you deal with reading and writing messages, you can keep this threat out of your computer．When you exchange E-mail with someone else, the messages sent between you and that person pass through several computers before they reach their places．Imagine this conversation as it is taking place in an Internet“room”, a very, very big room．Anyone, or more exactly, any program can probably understand what is being said, because most Internet conversations are not hidden(隱藏)in any way．As a result, others may be listening in, capturing what you send, and using it for their own good．

　　E-mail-borne viruses(病毒)often arrive in attractive, fantastic appearances, much like the beautiful ads we receive by way of traditional mail that is made to sell us something．By beautiful appearances, an infected(感染)E-mail message seems to be something we want to read from someone we know, not a mean virus ready to destroy or damage our computers．

　　There are some steps that you can take to help you decide what to do with every E-mail message with an attachment(附件)that you receive．You should only read a message that passes all of these tests：

　　1)The Know Test：Is the E-mail from someone that you know?

　　2)The Received Test：Have you received E-mail from this sender before?

　　3)The Expect Test：Were you waiting for E-mail with an attachment from this sender?

　　4)The Meaning Test：Do the topic line of the E-mail massage and the name of the attachment both have meanings?

　　5)The Virus Test：Is the E-mail infected?

(1)

Which of the following is the main idea of the first paragraph?

[　　]

A．

We should not exchange our E-mail with someone else．

B．

It is dangerous to read and write E-mail message sat home．

C．

We should learn how E-mail works to take care of our computers．

D．

Our chats on computers are usually going on in a big Internet room．

(2)

What does the underlined word“capturing”probably mean?

[　　]

A．

taking

B．

hiding

C．

receiving

D．

destroying

(3)

As the Internet is open to anyone, we should ________．

[　　]

A．

not read and write messages in our home computers

B．

not allow nice advertisements to reach our computers

C．

stop our conversations while someone is listening in it

D．

be careful with the attractive E-mails sent by strangers

(4)

What is the passage mainly talking about?

[　　]

A．

The threats of E-mail．

B．

The safety of home computers．

C．

The E-mail-borne viruses．

D．

The steps to receive E-mail messages．

　　At f　　7　　 the Internet was only used by the government, but, in the early 1970s, universities, hospitals and banks were allowed to use it too．H　　8　　, computers were still very expensive and the Internet was d　　9　　 to use．By the start of the 1990s, c　　10　　 became cheaper and easier to use．Scientists had also developed software that made 'surfing'(瀏覽)the Internet more convenient．

Hi Eric,
　　We don’t have smog in Oxford. We get fog sometimes, but that’s all. Oxford is much smaller than LA. We only have about 135,000 people. I looked up the 1900 population, it was about 57,000. So it is about twice as many people, not ten times as many, like LA! Oxford is much smaller than London - London has about 7,000,000 people. So that means that LA has more people than London. LA gets hotter than Oxford. We have colder winters too – it can be -4°C in winter.
　　I’m not surprised that your new student only knew about the university. It is famous because it is one of the oldest universities in the country. There are about 18,000 students. The brother of my best friend is at Aberystwyth University, in Wales. There the population is 14,000 and half of that are students! It must be a strange place to live! There are more tourists in Oxford than students, I should think. We get a lot of tourists, all year round. We also get a lot of young foreign students because there are a lot of language schools here. You can stand in the middle of Oxford, close your eyes, and hear accents from all over the world!
　　Your e-mail friend, Ben

　　　 My summer hols wr CWOT. B4, we used 2 go 2 NY2C my bro, his GF&thr 3 :-@ kids FTF. ILNY, its gr8.

　　　 Can you understand this sentence? If you can’t, don’t feel too bad: neither could the middle school teacher in England who received this as homework. This is Netspeak: the language of computerized communication found on Internet of cellphones. To newcomers, it can look like a completely foreign language. So, what is the “translation” of the sentence above? My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three screaming kids face to face. I love New York; it’s great.

　　　 Schoolteachers and parents say this new form of writing is harming(破壞) the English language. Increasing spelling and grammatical mistakes can be seen in students’ writing. They fear the language could become corrupted(面目全非的).

　　　 Everyone should just relax, say linguists(語(yǔ)言學(xué)家). They believe Netspeak is in fact more of a good thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again. Geoffrey Nunberg, from Stanford University, agrees. “People get better at writing by writing,” he says. “Kids who are now doing text messaging, e-mail, and instant messages will write at least as well as, and possibly better than, their parents.

　　　 Linguist James Milroy says, for centuries, it is believed without exception that young people are harming the language. And you can bet your bottom dollar that when today’s teenagers become tomorrow’s parents, they too will thing this way. Milroy argues that languages do not and cannot become “corrupted”; they simply change to meet the new needs.

　　　 However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English. Cynthia McVey says, “I can understand Netspeak worries teachers and it’s important that they get across to their pupils that text messaging is for fun, but that learning to write proper English is a must for their future.”

　　　 Perhaps we should give teenagers a little more trust anyway. Erin, age 12, says, “I wouldn’t use text language in my homework. Texting is just for fun.”

57. What is the main purpose of the first paragraph?

　　　 A. To give an example of a foreign language.

　　　 B. To show an example of creative methods.

　　　 C. To express worries about using Netspeak.

　　　 D. To lead in the topic of Netspeak.

58. Which of the following is true according to the passage?

　　　 A. Cynthia McVey points out teenagers can deal with Netspeak properly.

　　　 B. Geoffrey Nunberg believes Netspeakers can write Standard English.

　　　 C. David Crystal things Netspeak helps develop the habit of writing.

　　　 D. James Milroy says that language is changing and improving.

59. The expression “bet your bottom dollar” in Paragraph 5 means __________.

　　　 A. Be fairly sure　　　　　　　　　　　　　　　 B. be greatly surprised　　　　　

　　　 C. think it a pity　　　　　　　　　　　　　　 D. find it interesting

60. What can be the best title fro the passage?

　　　 A. Netspeak: A Widely-Used Language on Internet

　　　 B. Is Netspeak Harming the English Language?

　　　 C. Is Netspeak Helpful in the English Language?

　　　 D. Netspeak: Advantages and Disadvantages
