【正文】 e laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile of the route to estimate the length of cable that had to be manufactured. It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later , some of his findings aroused much popular interest in his book The Physical Geography of the Sea. The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea. Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition, which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a fivevolume report, the last volume being published in 1895. proposal to lay a telegraph cable from Europe to America made oceanographic studies take on ______.

The main topic of this passage is ______. A) why people built castles and their structure B) castles39。s chickens 正確答案是 Passage 10 The American Revolution was not a revolution in the sense of a radical or total change. It was not a sudden and violent overturning of the political and social framework, such as later occurred in France and Russia, when both were already independent nations. Significant changes were ushered in, but they were not breathtaking. What happened was accelerated evolution rather than outright revolution. During the conflict itself people went on working and praying, marrying and playing. Most of them were not seriously disturbed by the actual fighting, and many of the more isolated munities scarcely knew that a war was on. America39。s needs after the year20xx. 正確答案是 35. The application of advanced technology to research in solar energy ______. A) would lead to a big increase in research funding B) would make it unnecessary to import oil C) would make it possible to meet the future energy needs of the EEC D) would provide a much greater proportion of the Community39。 millions a year on solar research at Ispra,? one of the EEC39。s calculations go to the designer of the part, and he must make it as strong as the stress man says is 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 plete 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. When a plane has passed all the tests it can get a government certificate of airworthiness, without which it is illegal to fly, except for test flying. Making the working parts reliable is as difficult as making the structure strong enough. The flying controls, the electrical equipment, the fire precautions, etc. must not only be light in weight, but must work both at high altitudes where the temperature may be below freezing point and in the hot air of an airfield in the tropics. To solve all these problems the aircraft industry has a large number of research workers, with elaborate laboratories and test houses, and new materials to give the best strength in relation to we
