第2题

While a personal computer should continue to perform. predictably for years, veteran W

indows users know all too well that system instability is a fact of life. Yet you can minimize the glitches that you experience with your computer by heeding the tips below.

2. If you run Windows 98 or Windows Millennium, your computer should have at least 128 megabytes (MB) of RAM--and more if you find that your hard drive is churning a lot as you work with your applications. You can also get by with 128 MB of RAM if you use Windows NT or Windows 2000, but these operating systems will run much more smoothly if you have 256 MB of RAM or more.

3. Beta software, by its very nature, is pre-release software—meaning that it still has significant known bugs (or defects). The same goes, unfortunately, for many shareware programs. The authors of shareware programs, typically, have much less time and fewer resources available for testing their programs. Consequently, it&39; s far more common to find shareware software that is buggy.

4. No-name hardwares may be cheaper and sometimes just as good as name-brand products, but name-brand products usually became well-known because of their reliability. It&39;s also wise to buy products from reputable companies because Windows will more often support the hardware that you purchase. If you are starting out with computers, it&39;s also a good idea to buy ready-made systems from major manufacturers. These are likely to have tested thoroughly with your operating system, and you will generally experience fewer problems.

5. No matter how well your system runs when you get it, the day will come when it will need to be replaced. Hopefully, you will replace it because the technology has become outdated, but you may need to replace it also because the hard drive crashes or you begin experiencing problems that no one can figure out. That&39;s why it&39;s important to back up your important files regularly. Whether you use a tape backup device or a CD-RW drive, it&39;s important to map out a regular backup schedule and to stick to it.

Paragraph 2 ______

A. You Should Ensure That You Have As Much Memory (RAM) in Your PC As You NeedB. Do Prepare for DisasterC. Keeping a PC Running Smoothly Is Very DifficultD. Make Sure You Buy Good HardwareE. Avoid Installing Beta(试用自版) Software And Shareware SoftwareF. Install&39; as little software as possible

Paragraph 3 ______

Paragraph 4 ______

Paragraph 5 ______

Before you use a computer system, you should know ______.

A. the computer will slow downB. to fix something that isn&39;t brokenC. how to keep your PC stableD. copy files from the hard disk onto two sets of floppy disksE. your system is running wellF. the authors have much less time for, testing their programs

When a hard disk gets too full, ______.

To save data, it is a good idea always to ______.

Many shareware programs are buggy because ______.

Robots

1．The most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.

2．Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接),spray-painting and assembling components.

3．In Britain, robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.

4．It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.

5．It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan.

6．The reliability of robots is measured in their M.T.B．F． or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small sample.

7．The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. Once programmed, the robots can work more accurately and consistently than humans, who can get tired and bored.
