To us, it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun. Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the 1th century B.C. We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and authority. In the Far East, in ancient times, the umbrella was allowed to be used only by royalty or by those in high office. In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans. During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered a symbol of power and authority. By 1680, the umbrella appeared in France, and later on in England. By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It was not until the twentieth century that women’ s umbrella began to be made, in a whole variety of colors. Which of the following in NOT true about the umbrella
A. No one exactly knows who is the inventor of the umbrella.
B. The umbrella was first invented to be used as protection against the sun.
C. The umbrella changed much in style in the eighteenth century.
D. In Europe the Greeks were the first to use the umbrella as a sunshade.

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. If you want to use Windows 2000, but your computer only has 64 MB, what will you have to do
A. Enlarge its RAM to at least 256 MB.
B. Put in good software in your computer.
C. Enlarge its RAM to at least 128 MB.
D. Buy a new computer.
