This is an area of the western Atlantic between Bermuda and Florida, roughly triangular in shape where since 1945 at least a hundred ships and planes and over a thousand people have disappeared. No wreckage had been found, no bodies, lifebelts or any other evidence of disater. It is as if these planes, ships and people had never existed. In some cases a routine radio message has been received from aircraft reporting everything in order a few minutes before all contact was lost, in others a weak S. O. S message has been picked up and, in perfect weather, inexplicable references to fog and loss of bearings. In the extraordinary case of five U. $. navy planes disappearing on a routine mission from Florida, the rescue place sent to locate them vanished also. There have been references to the curious white light or haze which is a feature of the sea in part of this area, and it is interesting to note that not only was this light, or streaks of light, observed by the astronauts on their way to space, but was also noted by Columbus, five centuries ago. Whether this light has any connection with the mysterious disappearance is unknown-it is just another curious circumstance as yet unexplained. Many theories, some bordering on the fantastic, have been advanced to account for the disturbing incidents that occur in the area of the Bermuda Triangle. It has been asked whether these disappearances are caused by extraterrestrial activity, by some undiscovered source of energy, or some dimension of time or space unguessed at by Man. This is no answer and speculation continues as anxiety increases.

单选题{{B}}第二篇{{/B}} A Historical Development of Oil Refining An important new industry, oil refining(炼油) ,grew after the Civil War. Crude oil, or petroleum-a dark, thick ooze from the earth-had been known for hundreds of years. But little use had ever been made of it. In the 1850's, Samuel M. Kier, a manufacturer in western Pennsylvania, began collecting the oil from local seepages (油苗)and refining it into kerosene (煤油), Refining, like smelting(锻造), is a process of removing impurities from a raw material. Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was becoming harder to get. Soon there was a large demand for kerosene. People began to search for new supplies of petroleum. The first oil well was drilled by E. L. Drake, a retired railroad conductor. In 1859 he began drilling in Titusville, Pennsylvania. The whole venture seemed so impractical and foolish that onlookers called it" Drake's Folly". But when he had drilled down about 70 feet(21 meters) ,Drake struck oil; his well began to yield 20 barrels of crude oil a day. News of Drake's success brought oil prospectors (探寻者)to the scene. By the early 1860s these wildcatters (盲目采油者) were drilling for "black gold" all over western Pennsylvania. The boom rivaled the California gold rush of 1848 in its excitement and Wild West atmosphere. And it brought far more wealth to the prospectors than any gold rush. Crude oil could be refined into many products. For some years kerosene continued to be the principal one, it was sold in grocery stores and door to door. In the 1880s and 1890s refiners learned how to make other petroleum (石油) products such as waxes (石蜡) and lubricating oils (润滑油). Petroleum was not then used to make gasoline or heating oil.

单选题After a generation of non-fault divorce in America, law-makers in some states are being asked to make it harder to end a marriage when one spouse does not want to call it off. Proposals in several states to make contested divorces harder to obtain are supported by conservative groups seeking to promote their concept of family values. These proposals would go back, in contested divorces cases, the old requirement that one spouse should show the other was "at-fault", such as being unfaithful, abusive, a drug user or someone who deserts the marriage. That would be a big shift from current divorce laws. No-fault divorce law has been enacted throughout America since California put the first one on the books in 1970. Under such laws, someone can get a divorce on grounds that the marriage has broken down without having to claim wrongdoing by the other spouse. No-fault divorces can be obtained even if one spouse does not agree to dissolve the marriage. No-fault divorce law first came into practice inA. a state in the west.B. a state in the upper mid-west.C. a state in the east.D. a state in the nort

单选题Car Thieves Could Be Stopped Remotely Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in a nasty surprise. The car is fitted with a remote immobilizer, and a radio signal from a control center miles away will ensure that once the thief switches the engine (51) , he will not be able to start it again. For now, such devices (52) only available for fleets of trucks and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars, and (53) be available to ordinary cars in the UK (54) two months. The idea goes like this. A control box fitted to the car incorporates (55) miniature cellphone, a microprocessor and memory, and a GPS satellite positioning receiver. (56) the car is stolen, a coded cellphone signal will tell the unit to block the vehicle's engine management system and prevent the engine (57) restarted. There are even plans for immobilizers (58) shut down vehicles on the move, though there are fears over the safety implications of such a system. In the UK, an array of technical fixes is already making (59) harder for car thieves. "The pattern of vehicles crime has changed," says Martyn Randall of Thatcham, a security research organization based in Berkshire that is funded in part (60) the motor insurance industry. He says it would only take him a few minutes to (61) a novice how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old. Modern cars are a far tougher proposition, as their engine management computer will not (62) them to start unless they receive a unique ID code beamed out by the ignition key. In the UK, technologies like this (63) achieve a 31 per cent drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars. Often by getting hold of the owner's keys in a burglary. In 2000, 12 per cent of vehicles stolen in the UK were taken by using the owner's keys, which doubles the previous year's figure. Remote-controlled immobilization system would (64) a major new obstacle in the criminal's way by making such thefts pointless. A group that includes Thatcham, the police, insurance companies and security technology firms have developed standards for a system that could go on the market sooner than the (65) expects.
