Long before he started

16、a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891. Although it was by no means the first popular automobile, the Model T showed the world just how creative Ford was at combining technology and market

17、. 2 The companys assembly line alone threw Americas Industrial Revolution into overdrive (高速运转 ). Instead of having workers put together the entire car, Fords friends, who were great toolmakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Fords

18、 Highland Park plant was humming (嗡嗡作响 ) along in 1914, the worlds first automatic conveyor belt could turn out a car every 93 minutes. 3 The same year Henry Ford shocked the world with the 5-a-day minimum wage scheme, the greatest contribution he had ever made. The average wage in the auto industry

19、 then was 2.34 for a 9-hour shift. Ford not only doubled that, he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didnt involve an awful lot of training or education. The Wall Street Journal called the plan “an economic

20、 crime“, and critics everywhere laughed at Ford. 4 But as the wage increased later to daily $10, it proved a critical component of Fords dream to make the automobile accessible (可及的 ) to all. The critics were too stupid to understand that because Ford had lowered his costs per car, the higher Wages

The original chocolate drink was mad

24、e from the seeds of the cocoa tree (可可树 ) by South American Indians. The Spanish introduced it to the rest of the world during the 1500s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still

25、 exist today; The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “Potato Famine (饥荒 )“ of 1845-1846, and thousands mer

26、e were forced to leave their homeland and move to America. There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the worlds largest grower of coffee, and coffee is an important crop in Colombia and other South

27、 American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400s. According to an Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and

28、 experienced the “wide-awake feeling that one third of the worlds population now starts the day with. 31 According to the passage, which of the following has changed the most in the last 500 years? （ A） Food. （ B） Clothing. （ C） Ideology. （ D） Language. 32 “Some“ in the last sentence of the first pa

Now, in test fli

32、ghts over the Rocky Mountains, NASA (美国航空航天局 ) engineers have successfully detected clear-air turbulence up to 10 seconds before an aircraft hits it. Clear-air turbulence often catches pilots by surprise. Invisible to radar, it is difficult to forecast and can hurl (用力抛出去 ) passengers about the cabi

33、n. In December 1997, one passenger died and a hundred others were injured when unexpected rough air caused a United Airlines flight over the Pacific to drop 300 metres in a few seconds. However, passengers can avoid serious injury by fastening their seatbelts. “It is the only antidote (对策 ) for this

34、 sort of thing,“ says Rod Bogue, project manager at NASAs Dryden Flight Research Center in Edwards, California. The centres new turbulence detector is based on lidar, or laser radar. Laser pulses are sent ahead of the plane and these are then reflected back by particles in the air. The technique dep

35、ends on the Doppler effect. The wavelength of the light shifts according to the speed at which the particles are approaching. In calm air, the speed equals the planes airspeed. But as the particles swirl (打漩 ) in rough air, their speed of approach increases or decreases rapidly. The rate of change i

36、n speed corresponds to the severity (激烈程度 ) of the turbulence. In a series of tests that began last month, a research jet flew repeatedly into disturbed air over the mountain ridges (山脉 ) near Pueblo, Colorado. The lidar detector spotted turbulence between 3 and 8 kilometres ahead, and its forecasts

37、 of strength and duration corresponded closely with the turbulence that the plane encountered. Bogue says that he had “a comfortable amount of time“ to fasten his seatbelt. The researchers are planning to improve the lidars range with a more powerful beam. The system could be installed on commercial

38、 aircraft in the next few years. 36 What does “clear-air turbulence“ probably mean? (Paragraph 1) （ A） A not very rough storm. （ B） Unexpected disturbed air. （ C） A kind of visible storm. （ D） A storm over mountain ridges. 37 In December 1997, a United Airlines flight hit unexpected rough air, （ A）

39、causing a let of damage to the plane. （ B） throwing its passengers out of the cabin. （ C） resulting in heavy casualties. （ D） forcing the pilot to make an emergency landing. 38 The turbulence detector can tell the severity of the turbulence by measuring （ A） the speed of the plane. （ B） the speed, o

40、f the light. （ C） the number of particles in the air. （ D） the changes of the particles speed. 39 We can infer from the fifth paragraph that （ A） the lidar detector can successfully forecast turbulence. （ B） researchers are not sure about the effectiveness of the lidar detector, （ C） passenger plane

41、s will be used in further experiments. （ D） no more test flights are needed. 40 The last paragraph tells us, among other things, that （ A） the lidar detector needs improvement. （ B） many airlines are interested in the system. （ C） passengers often forget to fasten their seatbelts. （ D） the lidar det

42、ector can be used in a wide range of areas. 41 “Salty“ Rice Plant Boosts Harvests British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, f

43、rom Sussex Universitys School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to esta

44、blish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice. It is estimated that each year more than 10m hectares (公顷 ) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长 ) plants. The problem is ca

45、used by several factors. In the tropics, mangroves (红树林 ) that create swamps (沼泽 ) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透 ) in. In Latin America, irrigation ofte

46、n causes problems when water is evaporated (蒸发 ) by the heat, leaving salt deposits behind. Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive. To overcome these problems, Flowe

47、rs and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be c

48、onsidered for commercial use. Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food in the poorer c

49、ountries of the world. 41 Which of the following statements about Flowers and Yeo is true? （ A） They are students at Sussex University. （ B） They are rice breeders. （ C） They are husband and wife. （ D） They are colleagues at an institution of higher learning. 42 Flowers and Yeo have started a programme （ A） to find ways to prevent water pollution. （ B） to identify genes that promote growth in salty soil. （ C） to breed rice plants that taste salty. （ D） to f
