【正文】 m, all it didwas to increase their costs per barrel of oil found. The Russian State Oil Company isunder a statutory obligation imposed by its government to put to the test every claimto an oilfinding method, be it a dowsing or some sophisticated scientific technique.There are many examples of the previous case, and some scientists argue thatdrilling according to a set of scientific data has the same oute as drillingrandomly. Petroleum geology is only one aspect of petroleum exploration andproduction. Leaving aside atypical (t~) enterprises, petroleum exploration nowinvolves integrated teams of people possessing a wide range of professional skills.These skills include deep knowledge of local social situations, which is involved inthe purchase of potential oil fields especially in developing countries. Geophysicalsurveying is involved in collecting data that helps people decide where drilling ismost appropriate. Petroleum engineering is concerned with activities related to themost effective way of producing crude oil and natural gas.B級(jí)：71. (~)Geologists, in contrast to some nongeologists, believe that knowledge of theconcepts of geology can help to find petroleum. ~Some petroleum explorationists still do not admit to a need for geologists toaid them in their search. In 1982 a successful oil finder from Midland, Texas,admitted to not using geologists because when his petitors hired them, all it didwas to increase their costs per barrel of oil found. There are many examples of theprevious case, and some scientists argue that drilling according to a set of scientificdata has the same oute as drilling randomly. ~Petroleum geology is only one aspect of petroleum exploration andproduction.

Being inventive and imaginative, in 1867, he 63 inventing a new explosive,dynamite, which made him worldfamous. During his life time, he took more than100 patents. But he was not interested in 64, he was most generous 65 the poor.His 66 wish was to bring happiness and peace to the whole world. That was why hehad devoted 67 his time and money 68 this cause and at his death in 1896, AlfredNobel, in his famous 69, 70 all his money $9,200,200 to set up a fund to provideprizes for the most outstanding work in physics, chemistry, physiology or medicine,literature, peace and economics.61.

The sand blows through the city streets and piles up against walls and fences. The desert stretches out as far as the eye can see. In some parts of the Amazon rain forest in Brazil, all the trees have been cut down. The earth lies bare and dry in the hot sun. Nothing grows there anymore. Over vast areas of every continent, the rainfall and vegetation necessary for life are disappearing. Already more than 40 percent of the earth39。s Samuel M. Kier, amanufacturer in western Pennsylvania, began collecting the oil from local seepageand refining it into kerosene. Refining, like smelting, is a process of removingimpurities from a raw material. Kerosene was used to light lamps. It was a cheap substitute for whale oil, whichwas being harder to get. Soon there was a large demand for kerosene. Peoplebegan to search for new supplies of petroleum. The first oil well was drilled by . Drake, a retired railroad conductor. In 1859he began drilling in Titusville, Pennsylvania. The whole venture seemed soimpractical and foolish that onlookers called it Drake39。s shell reached the darkest color at the same time in Cape Cod, Massachusetts and its neighboring island B. the fiddler crab continued to change color in the dark C. plants will not grow without sunlight D. all of the above 42.
