单选题For laymen ethnology is probably the most interesting of the biological sciences for the very reason that it concerns animals in their normal activities and therefore, if we wish, we can assess the possible dangers and advantages in our own behavioral roots. Ethnology also is interesting methodologically because it combines in new ways very scrupulous field observations with experimentation in laboratories. The field workers have had some handicaps in winning respect for themselves. For a long time they were considered as little better than amateur animal-watchers certainly not scientists, since their facts were not gained by experimental procedures: they could not conform to the hard-and-fast rule that a problem set up and solved by one scientist must be tested by other scientists, under identical conditions and reaching identical results. Of course many situations in the lives of animals simply cannot be rehearsed and controlled in this way. The fall flocking of wild free birds can't be, or the homing of animals over long distances, or even details of spontaneous family relationships. Since these never can be reproduced in a laboratory, are they then not worth knowing about? The ethnologists who choose field work have got themselves out of this impasse by greatly refining the techniques of observing. At the start of a project all the animals to be studied are live-trapped, marked individually, and released. Motion pictures, often in color, provide permanent records of their subsequent activities. Recording of the animals' voices by electrical sound equipment is considered essential, and the most meticulous notes are kept of all that occurs. With this material other biologists, far from the scene, later can verify the reports. Moreover, two field observers often go out together, checking each other's observations right there in the field. Ethnology, the word, is derived from the Greek ethos, meaning the characteristic traits or features which distinguish any particular group of people or, in biology, a group of animals such as a species. Ethnologists have the intention of studying "the whole sequence of acts which constitute an animal's behavior." In abridged dictionaries ethnology is sometimes defined simply as "the objective study of animal behavior," and ethnologists do emphasize their wish to eliminate myths.

单选题{{B}}Passage Four{{/B}} Today, the Indianapolis 500, one of the world's most famous car races, takes about four hours to run. If the Indy 500 had been held in 1895, it would have taken almost three days. The horseless carriage had just been invented a short time before. Top speeds back then were much lower than they are today. For most people, just seeing a car move without a horse pulling it was thrilling enough. The driver's main concern was making sure the car didn't break down. One of the first car races was held in Chicago on Thanksgiving Day in 1895. Folks crowded the streets to gawk at the new machines. The route of the race went through the heart of town. The cars were to go out to a nearby suburb and back. The race covered a distance of about 54 miles. That's less than one-tenth the distance at Indy. The drivers cranked up their engines and prayed that they wouldn't break down. Then they were off. The race proved too much for some of the cars. Perhaps they couldn't withstand the high speeds. The winner of the contest was J. Frank Duryea. He finished the race a bit more than seven hours after he started. He had covered the grueling distance at an average speed of 7.5 miles per hour. That is slower than a modern marathoner can go on foot. Even so, as Duryea finished, the crowd went wild.

单选题When Abraham Lincoln was a lawyer in rural Illinois, he and a certain judge in town once got to bantering with one another about horse trading. The upshot of the discussion was that they agreed that the next morning, at nine o'clock, they would meet in front of the general store and make a trade. Each would bring a horse, unseen by anyone up to that hour. If either backed out of the deal, he would forfeit $25. The money from each man was held by the local banker. The next morning, at the appointed hour, the Judge, came up the dirt road, leading the sorriest looking specimen of a horse ever seen in those parts of Illinois. The large crowd viewing the spectacle burst out laughing, already knowing that Abe Lincoln was bound to get the worst of the deal. A poorer horse just couldn't exist anywhere and still he walking. In a few minutes, however, Mr. Lincoln was seen approaching the general store carrying something quite large and bulky on his shoulders. As he drew nearer, the crowd saw what it was, and great shouts and laughter broke out. The shouts and laughter soon broke into a thunderous roar when Mr. Lincoln, looking carefully and seriously over the Judge's animal, set down his sawhorse (锯架), and exclaimed, "Well, Judge, this is the first time I ever got the worst of it in a horse trade./

单选题Amazon today unveiled Dash Buttons, an easy way for customers to 1 select bulk goods 2 an internet-connected button, and yesterday 3 Home Services, an on-demand installation and handyman service.
