　　46.Cyberspace，of course， is bigger than a telephone call. It encompasses the millions of personal computers connected by modems—via the telephone system—to commercial online services， as well as the millions more with high-speed links to local area networks， office E-mail systems and the Internet. It includes the rapidly expanding wireless services： microwave towers that carry great quantities of cellular phone and data traffic； communications satellites strung like beads in geosynchronous orbit； low-flying satellites that will soon crisscross the globe like angry bees， connecting folks too far-flung or too much on the go to be tethered by wires. Someday even our television sets may be part of cyberspace， transformed into interactive “teleputers” by so-called full-service networks like the ones several cable-TV companies（including Time Warner） are building along the old cable lines， using fiber optics and high-speed switches.

　　Ⅵ。Directions：Read through the following passages and choose the best answer marked A，B，C or D.（20%）

　　There are two main things that make aircraft engineering difficult； the need to make every component as reliable as possible and the need to build everything as light as possible. The fact that an aeroplane is up in the air and cannot stop if anything goes wrong， makes it perhaps a matter of life or death that its performance is absolutely dependable.

　　Given a certain power of engine， and consequently a certain fuel consumption， there is a practical limit to the total weight of aircraft that can be made to fly. Out of that weight as much as possible is wanted for fuel， radio navigational instruments， passenger seats， or freight room， and， of course， the passengers or freight themselves. So the structure of the aircraft has to be as small and light as safety and efficiency will allow. The designer must calculate the normal load that each part will bear. This specialist is called the ‘stress man’。 He takes account of any unusual stress that may be put on the part as a precaution against errors in manufacture， acciedental damage， etc.

　　The stress man‘s calculations go to the designer of the part， and he must make it as strong as the stress man says if necessary. One or two samples are always tested to prove that they are as strong as the designer intended. Each separate part is tested， then a whole assembly， for example， a complete wing， and finally the whole aeroplane. When a new type of aeroplane is being made， normally only one of the first three made will be flown. Two will be destroyed on the ground in structural tests. The third one will be tested in the air.

　　Two kinds of ground strength tests are carried out. The first is to find the resistance to loading of the wings， tail， etc. until they reach their maximum load and collapse. The other test is for fatigue strength. Relatively small loads are applied thousands of times. Each may be well under what the structure could stand as a single load， but many repetitions can result in collapse. One from of this test is done on the passenger cabin.

　　It is filled with air at high pressure as for high-altitude flying and completely submerged in a large tank of water while the test is going
