【正文】 view of oil gene。 view of oil generation and migration are not accepted, thenpresent exploration methods would need extensive modification. 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. 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.

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.

Paragraph 4 says trees are cut for firewood. This is an example of A. Peru39。s deserts. Many countries are experiencing similar problems. Poor land is farmed until it is worn out, and trees are cut for firewood, leaving the soil unprotected against wind and rain. In Peru, Chile, and Brazil, some areas that once were covered with forests now look like the moon. In India, some land has been so badly damaged by farming and tree cutting that mud now slides into the Indus and Ganges rivers. Cattle, sheep, and goats add to the problem by eating grass and other plants faster than they can grow back. In the United States, some highly populated areas (such as Los Angeles)are really deserts. Water must be piped in from hundreds of miles awayand thisaffects the water supply of other California munities. Scientists still do not understand all the plex problems of the desert, butthere have been many ideas for saving the land. Saudi Arabia has planted 10 milliontrees to help keep the sand from taking over fertile areas. The Israelis are again using some of the water collection systems left by the ancient peoples in the Negev desert. They plan to water their orchards with the extra water. Some Sahel farmers still raise cattle on their poor farm land, but before the cattle are sold, they are taken to greener lands in the south to get fat. 57.
