听力原文： Hello, this message is for Jonathan Hasbrow. This is Cindy Hertz calling from Solid Security Inc. We will be installing a new security system in the building. On Tuesday we'll begin by replacing the video cameras for 3 days. Due to security concerns only the main entrance can be used for entering and exiting the building. All staff members are required to wear their identification passes at all times. There will be power disruptions, so it is recommended that all computers be protected as well as any experiments postponed until the changes are complete. I will be sending someone from Solid Security Inc. on Monday to address any concerns or requests you may have concerning the security installations. Thank you and have a good day.
What is being replaced？
A．The computer systems
B．The security office
C．Security cameras
D．The wireless Internet

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 Hopefully, you will replace it because the technology has become outdated, but you may need to replace it also because the hard drive crashes or you begin experiencing problems that no one can figure out.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.
