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

We are all busy talking about and using the Internet, but how many of us know about the history of the Internet?
  Many people are surprised when they find that the Internet was set up(建立) in the 1960s. At that time, computers were large and expensive. Computer networks(網(wǎng)絡(luò)) didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system(系統(tǒng)) had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way the computer network system would keep on working all the time.
  At first, the Internet was only used by the government, but, in the early 1970s, universities, hospitals and banks were allowed to use it too. However, computers were still expensive and the Internet was difficult to use. By the start of the 1990s, computers become cheaper and easier to use. Scientists had also developed software(軟件) that made “surfing(瀏覽)” the Internet more convenient (方便).
  Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.

閱讀下面短文,根據(jù)短文內(nèi)容完成表格中所缺信息,每空一詞。

One of the most common questions I am asked is whether, when, and how to follow up after a job interview. Following up in some way is necessary. Yes, you can get a job without it, but if you compete with other top candidates(候選人), following up can sometimes help you when the other candidate doesn’t. Here’s how to follow up well:

Send a thank-you note at once. E-mail is fine for this and has the advantage of arriving faster, but handwritten notes are still appreciated (欣賞). And if there are many interviews(面試), send a thank-you note each time.

Find out their timeline. Hopefully, you asked about their timeline in the interview itself, but if you didn’t, follow up within a week to strengthen your interest and politely ask what they expect their timeline for a decision to be.

Be patient. Most commonly, job seekers are too worried about the result. It doesn’t look worried to express your interest in the job or check in to ask about the timeline.

Don’t be nervous if you don’t hear from them at once. The hiring process often takes longer than a candidate would like, maybe the decision makers are out of town. If you’re past the time they indicated you would hear something, this isn’t necessarily cause for nervousness. Hiring often ends up taking longer than expected. Just politely follow up, explain you’re very interested but understand that hiring can take time, and ask if they have the latest timeline.
