city, efficiency and versatility that they have practically "invaded" almost each and every human domain(领域). They have undoubtedly gone far beyond the expectations of a generation that had already lived under the spell(一段时间) of the TV set.
Throughout history there have been inventions that have been particularly remarkable and influential(有影响力的) within the scope of transport, education, health or communication. They have brought out comfort, health, knowledge or power. Some of them have produced minor effects; others have brought about very great changes. Think of the invention of the wheel, the automobile or the printing press, and what about the computer？
At the beginning the computer was thought mainly as an instrument to be used in the mathematical field, but soon people from other sciences began to get interested in this little "brain" that was capable of performing thousands of operations in a few seconds without getting tired or confused. They realized it could not only store millions of pages of information but also organize it in every possible way enabling man to carry out tasks unthinkable by other means.
Computers are now everywhere. They can make vehicles at supersonic(超音速的) speed and precision; they can control world banking transactions(交易), predict weather conditions, conduct an aircraft or a space craft, play instruments, manage nuclear weapons; they can operate on human patients, they can transfer information from one continent to another in seconds, they can...they can...they can... Yet, thank God, they still need human beings: to draw the instructions, to design the programs or to push the button!

M: Sorry, but I can't believe that you're actually complaining about free publicity. I mean I remember, Shelley, before you were famous, you were begging us to write features about you...anything...
W: If you would just let me finish of course the press have been important. I'm an actress and I understand the power of the press. But the thing is, I rarely seem to read anything true about myself these days... The point I'm trying to make here is that famous people have families with feelings.
M: Oh, sorry. You're really hurt by that particular article last week.
W: To increase circulation and make more money, certain newspapers continue to print those stories when it's obvious that they're not true.
M: But I think we have to consider the relationship between fame, the public and the press. The public are fascinated by fame and scandal, and they love to read about their favorite stars.
W: I'm sick of gutter-press making up stories. It's irresponsible and it messes up people's life.
M: The problem is, it's not always clear what's true and what isn't. I mean, if a newspaper prints something scandalous or embarrassing about a famous person, they're bound to deny it, but that doesn't mean it's not true.
W: Are you trying to say...
M: No smoke without fire, if you ask me.

Most companies expect IT (Information Technology) managers to head an IT staff of computer technicians. But IT managers can also specialize in other areas. Some managers may also be responsible for keeping their company’s Internet safety. They protect both their company and their online customers from thieves.
Other managers focus more on the business rather than the technical part of computing. They become project managers, helping companies reach as many online customers as possible.
Some companies also look for IT managers who can act as trainers. These trainers help a company’s computer technicians keep up-to-date on computer skills.
Most companies require their IT managers to have both a bachelor’s degree and some experience in the computer field. Often, companies hire IT managers out of their existing staff of computer technicians.
Since IT managers are extremely important to companies’ success, it’s no surprise that they receive such high salaries – around US $56,000 a year to start with. And, in such a fast-changing field,
managers’ salaries usually increase after only a couple of years.
The world will be watching to see just how quickly e-commerce replaces the old ways of doing business. And as computers change the way the world does business, IT managers will be in the middle of it all. Few companies can survive without them.
Besides being the leader of computer technicians, IT managers are also expected to be ________.
(A) experienced product designers
(B) skilled online technicians
(C) doctorate holders
(D) online safety specialists
k)
