问题     In many parts of the world cars play an essential role in daily life and many societies would cease to function without them. So, tile claim that in 20 years’ time, no one will own cars may be hard to believe. But this is tile prediction made by a team of transport researchers who are taken seriously,  not only by governments but also by car manufacturers.
    The Human Science and Advanced Technology Institute at Loughborough in the U. K. is part of an international research program. The team there believes that by 2020 all cars will be computerized which will mean gigantic fuel savings, no accidents and better use of roads. The super-intelligent car of the 21 st century will drive itself, and it will not be owned by one individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.
    According to Dr. David Davies, who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths’ than both world wars put together. Davies says, cars will be fitted with intelligent cruise-con-trol devices to regulate the distance between one car and another. Brakes and accelerators will become  redundant(多余的) because the car will automatically speed up, or slow down, to match the speed of the car in front. Computers are much safer drivers than people, so cars and trains will be able to drive much closer together than cars driven by people.
    By 2010, David Davies maintains, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead onto the car’s windscreen. And, by 2020, cars will travel in convoy, linked to each other electronically. Cars will be connected by an electronically bar to the car in front to form "road-train". "The front vehicle in such a train," says Davies. "But all the others in the train would burn about ten percent of the normal amount, and so produce about ten percent of the poollution."
The expression "in convoy" (Line 3, Para. ) is closest in meaning to"______"
选项 A、in line
B、in defence
C、side by side
D、next to one another
答案A
解析 语义理解题。本句的意思是：到2020年，通过车与车之间建立的电子联系，汽车将实现以 convoy 的形式来行驶；然后根据下文中“每辆汽车都将与前面的汽车相连，并组成一种所谓的‘公路火车’”可以推断出，汽车是成一条直线行驶的。
