"I can't write you out a ticket. The computer is the only one allowed to do so."
I looked down on the computer and every passenger was just standing there staring at the black screen. Then I asked her, "What do all you people do？'
"We give the computer the information about your trip, and then it tells us whether you can fly with us or not."
"So when it goes down, you go down with it."
"That's good, sir. '
"How long will the computer be down？" I wanted to know.
"I have no idea. There's no way we can find out without asking the computer."
After the girl told me they had no backup (备用) computer, I said. "Let's forget the computer. What about your planes？ They're still flying, aren't they？"
"I wouldn't know," she said, pointing at the dark screen. "Only 'IT'knows. 'It'can't tell me.

A lot of kids are getting online these days—sharing data, talking about social issues, meeting adults as well as kids, and learning about other cultures. There seems to be everything on the network. Just like any other form. of media, the quality of this massive collection of information is
unequal, and there is good information as well as rubbish. Networks hold great promise: however,
it's also home to people who mean to hurt others or use their technical knowledge to steal from them . Although many Web pages can teach kids useful things, there are some other sites waiting to temp young people who are immature and easily affected.
By now, you may shake your head, but wait, let's try to put the problem into perspective Generally.it's safe for kids to use the Internet. The number of sites considered harmful is between 1% and 3%, which shows about 4.5 million other sites are interesting and educational. Besides, to stop children from using these services just because crimes are being committed online would be like telling them not to attend college because students may have accidents on campus.
What can parents do to protect their children from those harmful sites？ The simplest solution is the use of programs which block offensive sites. Such programs are set to screen out certain words likely to appear on”unhealthy”sites. But many sites inappropriate to young people are clever at using words with double meanings that may appear harmless. What's more, not only do the programs fail to do the job satisfactorily, they also take away the decisive role of parents in children's education. A child who downloads bad information or pictures can only be corrected by positive family influence. No filtering program is necessary for a child who has learned to say“no”to sites he knows are inappropriate for him.
Today, when children are exposed to technology at a young age, parents often find themselveslagging behindin computer skills. Surprisingly, this may be the key to your involvement. What is better way to learn about the Internet than to do so alongside your children？
They'll most likely pick it up more quickly than you do, of course, but you'll have the chance to see, and take pride in, your child at work. You may search for information that interests your child together with him and get to know the”friends”he has online, just as you would get to know his other friends.
Thoughtful parents would combine supervision with communication, which is the best way to take advantage of the Internet as a resource while protecting their children. Follow their examples and have fun with kids on the Net!

Finding a good work-at-home job is not easy. Although you see all the online advertising, there aren't that many of them. Those that are available may require that you live in a certain area or spend at least some time in the office. Others may be only part-time jobs. Keep in mind that the skills needed for home employment are similar to those needed for working in an office. You'll also need a home office with a high speed internet connection, phone, fax, computer, printer, and other basic office equipment. To get started, consider your job search as your job. Spend as many hours per week on your job search as you would spend working. If you're looking for full-time work, you should be spending fill-time hours seeking a job. Networking (人际关系) remains the top way to find a job and it does work. Develop contacts—friends, family, even the other job seekers—anyone who might have the information you need. You can take a direct approach and ask for job information or try a less formal approach and ask for information and advice. Contact everyone you know and tell them you want to work from home. You may be surprised by the people they know and the job information they can provide.
According to the first paragraph, it is not easy to find good work-at-home jobs because ______.
A、they are seldom advertised online or in newspapers
B、they may require that you live in a certain place
C、you are always asked to work full-time
D、you need to have a college degree
Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something had gone wrong. Questioning and routine double checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the following warning: For all the help this computer may provide, it should not be seen as a device that can take the place of fundamental thinking and reasoning skills.
The main purpose of this passage is______.
A．to look back to the early days of computers
B．to explain what technical problems may occur with computers
C．to warn against a mentally lazy attitude towards computers
D．to discourage unnecessary investment in computers
The Solo Trek had a 120 horsepower engine with twin fans. Only one person flies. As you fly above the roofs, you lean a little forward. You can see everything under you. You are flying like Superman.
Michael Moshier looked at the jet belt and the rocket belt that was developed 20, 30 years ago. Nothing ever came from them. People still can't fly.
Inventors have tried to make it easy for people to fly. Paul Moiler has been working on his flying car for 30 years. He now says it is ready for tests. It would take off and land vertically, go 600 miles an hour, and deliver 20 miles to the gallon. A computer would do the actual flying. He says it could be sold next year for about a million dollars.
NASA is working with Moshier to help develop his flying machine. The first users are likely to be military.
It's been 50-years since Robert Fulton invented his airphibian, a flying car. It flew, and is now in the Smithsonian Museum.
