Many strange new means of transport have been developed in our century, the strangest of them being perhaps the hovercraft. In 1953, a former electronics engineer in his fifties, Christopher Cockerell, who had turned to boat-building on the Norfolk Broads, suggested an idea on which be had been working for many years to the British government and industrial circles. It was the idea of supporting a craft on a "pad", or cushion, of low-pressure air, ringed with a curtain of higher pressure air. Ever since, people have had difficulty in deciding whether the craft should be ranged among ships, planes, or land vehicles—for it is something in between a boat and an aircraft. As a ship builder, Cockerell was trying to find a solution to the problem of the wave resistance which wastes a good deal of a surface’s power and limits its speed. His answer was to lift the vessel out of the water by making it ride on a cushion of air, no more than one or two feet thick. This is done by a great number of ring-shaped air jets on the bottom of the craft. It "flies", therefore, but it cannot fly higher—its action depends on the surface, water or ground, over which it rides.
Which of the following statements is true

A:The engineer had worked out the idea for many years. B:The engineer had been working on the idea for many years. C:The engineer suggested the idea to the British government and industrial circles for many years. D:The British government and industrial circles accepted the idea many years later.

The simplest way of putting an idea down on paper is to draw a picture. That was (61) men first began to write, six thousand years ago or more. All (62) scripts (文字) have been developed from picture-writing of (63) sort. The English alphabet we now use (64) to us over a long period of time from the (65) of ancient Egypt.
Picture-writing, called hieroglyphics (象形文字), could be used to express (66) as well as objects. (67) , a drawing of a man would (68) the object "man", while (69) of a man lying on the ground (70) a spear in him would mean the idea "death". Later, some drawings came to stand for sounds as well. (71) in Egyptian hieroglyphics the (72) of a house stood (73) for the object "house" and for the sound "pr", (74) in spoken Egyptian meant "house".
(75) the Egyptians, the Chinese and the American Indians also developed their own kinds of picture-writing. However, with picture-writing, only (76) much could be said. Much more (77) to be left unsaid. It would have (78) hundreds of thousands of pictures to express (79) people wanted to express (80) a person could ever hope to learn in a life-time.
