问题     Getting a new PC is one thing. Keeping it running smoothly is quite another. While a personal computer should continue to perform well for years, users know that system unsteadiness (不稳定性) does exist. Yet you can reduce it to the smallest amount by following the tips below.
    First, put in as little software (软件) as possible. You’ll have fewer software-related problems and a system that is easier to manage.
    Second, you should ensure (确保) that you have as much memory (RAM) in your PC as you need. If you run Windows 98, your computer should have at least 128 megabytes (MB) of RAM and more. 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.
    Third, make sure you buy good hardware (硬件). No-name products may be cheaper and sometimes just as good as name-brand products, but name-brand products usually become well-known because Windows will more often support the hardware that you buy. If you are starting out with computers, it’s also a good idea to buy ready- made systems from major manufactures (制造商). They are likely to have been tested thoroughly with your operating system, and you will generally experience fewer problems.
    Fourth, do prepare for disaster. No matter how well your system runs when you get it, the day will come when it will need to be replaced. Hopefully (但愿), you will replace it because technology has become out-dated, but you may need to replace it also because the hard drive crashes (毁坏) or you begin experiencing problems that no one can figure out. That’s why it’s important to copy your important information regularly. Whether you use a tape backup device or a CD-ROM drive, it’s important to make a regular backup plan and stick to it.
What is the main purpose of this passage?
选项 A、To give some good advice about how to reduce computer system unsteadiness.
B、To stop people from buying no-name products.
C、To advertise the advantages of name-brand hardware.
D、To make known the unsteadiness of computer systems.
答案A
解析 主旨题。本文中有一句最关键的话，也就是本文的主旨句，它出现在 第一段，即“Yet you can reduce it to the smallest amount by following the tips below”。句中的it指的是上一句提到的system unsteadiness。所 以，本文的写作意图就是“对如何减小电脑系统的不稳定性”提出一些 建议。故答案是[A]。
