单选题{{B}}Passage 4{{/B}} In the late years of the nineteenth century, "capital" and "labour" were enlarging and perfecting their rival organisations on modern lines. Many an old firm was replaced by a limited liability company with a bureaucracy of salaried managers. The change met the technical requirements of the new age by engaging a large professional element and prevented the decline in efficiency that so commonly spoiled the fortunes of family firms in the second and third generation after the energetic founders. It was moreover a step away from individual initiative, towards collectivism and municipal and state-owned business. The railway companies, though still private business managed for the benefit of shareholders, were very unlike old family business. Meanwhile the great municipalities went into business to supply lighting, trams and other services to the taxpayers. The growth of the limited liability company and municipal business had important consequences. Such large, impersonal manipulation of capital and industry greatly increased the numbers and importance of shareholders as a class, an element in national life representing irresponsible wealth detached from the land and the duties of the landowners; and almost equally detached from the responsible management of business. During the nineteenth century, America, Africa, India, Australia and parts of Europe were being developed by British capital, and British shareholders were thus enriched by the world's movement towards industrialisation. Towns like Bournemouth and Eastbourne sprang up to house large "comfortable" classes who had retired on their incomes, and who had no relation to the rest of the community except that of drawing dividends and occasionally attending a shareholders' meeting to dictate their orders to the management. On the other hand "shareholding" meant leisure and freedom which was used by many of the later Victorians for the highest purpose of a great civilisation. The "shareholders" as such had no knowledge of the lives, thoughts or needs of employees in the company in which they held shares, and their influence on the relations of capital and labour was not good. The paid manager acting for the company was in more direct relation with the workers and their demands, but even he had seldom familiar personal knowledge of the workmen which the employers had often had under the more patriarchal system of the old family business. Indeed the mere size of operations and the number of workmen involved rendered such personal relations impossible. Fortunately, however, the increasing power and organisation of the trade unions, at least in all skilled trades, enabled the workmen to meet on equal terms the managers of the companies who employed them. The cruel discipline of the strike and lockout taught the two parties to respect each other's strength and understand the value of fair negotiation.

单选题The fossil remains of the first flying vertebrates, the pterosaurs, have intrigued paleontologists for more than two centuries. How such large creatures, which weighed in some cases as much as a piloted hang-glider and had wingspans from 8 to 12 meters, solved the problems of powered flight, and exactly what these creatures were—reptiles or birds—are among the questions scientists have puzzled over. Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not e- valve into the class of birds. In pterosaurs a greatly elongated fourth finger of each forelimb supported a wing like membrane. The other fingers were short and reptilian, with sharp claws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on all fours, the three short fingers may have been employed for grasping. When a pterosaur walked or remained stationary, the fourth finger, and with it the wing, could only turn upward in an extended inverted V-shape along each side of the animal"s body. The pterosaurs resembled both birds and bats in their overall structure and proportions. This is not surprising because the design of any flying vertebrate is subject to aerodynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight. In the birds, however, these bones are reinforced more massively by internal struts. Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T.H. Huxley reasoned that flying vertebrates must have been warm-blooded because flying implies a high rate of metabolism, which in turn implies a high internal temperature. Huxley speculated that a coat of hair would insulate against loss of body heat and might streamline the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hair—like fossil material was the first clear evidence that his reasoning was correct. Efforts to explain how the pterosaurs became airborne have led to suggestions that they launched themselves by jumping from cliffs, by dropping from trees or even by rising into light winds from the crests of waves. Each hypothesis has its difficulties. The first wrongly assumes that the pterosaurs "hind feet resembled a bat"s and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high waves to channel updrafts. The wind that made such waves however, might have been too strong for the pterosaurs to control their flight once airborne.

单选题Would you like to orbit the Earth inside the International Space Station? Now you can take a space holiday—for a price. This is due to a recent decision by top space officials of the United States, Russia, Canada, Japan and the European Space Agency. Last April, American businessman Dennis Tito reportedly paid between twelve million and twenty million dollars to spend one week on the International Space Station. NASA had strongly objected to the Russian plan to permit a civilian on the costly research vehicle. After two years of negotiations, space officials have agreed on a process to train private citizens to take trips to the International Space Station. NASA recently agreed to conditions that will permit Russia to sell trips to the space station. The trips are planned by an American company called Space Adventures Limited of Arlington, Virginia. The company calls itself "the world's leading space tourism company". The company has sold a space trip to Mark Shuttle-worth , a South African businessman. In April, Mr Shuttleworth will be launched into space from the Baikonur Cosmodrome in Kazakhstan. Experts say the change in policy at NASA shows a new desire to use space vehicles for business and industrial purposes. In a speech to Congress last year, NASA official Michael Hawes said that the space agency had not considered civilian travel as one of the industries it wanted to develop. However, Mr Hawes said that private space travel could now be done as long as safety measures are observed carefully. Yet, the average citizen will not be able to travel into space in the near future. Space Adventures Limited sells a training program for space flight that costs two hundred thousand dollars. That price does not include the cost of the trip to the International Space Station. That holiday in space costs twenty million dollars. Candidates for adventure space travel trips must be in excellent heaith and must pass difficult health tests. They must receive a lot of training. Besides, good English can help you prepare for a space holiday. This is because all successful candidates who wish to travel to the International Space Station must be able to read and speak English.
