Petrochemicals such as dyes, fertilizer, and plastic are also manufactured from the petroleum. 5在The word “adjacent” in the passage is closest in meaning to ○Nearby ○Existing ○Special ○Deep 6在Which of the following can be inferred from paragraph 3 about gushers? ○They make bringing the oil to the surface easier. ○They signal the presence of huge oil reserves. ○They waste more oil than they collect. ○They are unlikely to occur nowadays. Paragraph 4: As oil becomes increasingly difficult to find, the search for it is extended into morehostile environments. The development of the oil field on the North Slope of Alaska and the construction of the Alaska pipeline are examples of the great expense and difficulty involved in new oil discoveries. Offshore drilling platforms extend the search for oil to the ocean's continental shelves—those gently sloping submarine regions at the edges of the continents. More than onequarter of the world's oil and almost onefifth of the world's natural gas come from offshore, even though offshore drilling is six to seven times more expensive than drilling on land. A significant part of this oil and gas comes from under the North Sea between Great Britain and Norway. Paragraph 5: Of course, there is far more oil underground than can be recovered. It may be in a pool too small or too far from a potential market to justify the expense of drilling. Some oil lies under regions where drilling is forbidden, such as national parks or other public lands. Even given the best extraction techniques, only about 30 to 40 percent of the oil in a given pool can be brought to the surface. The rest is far too difficult to extract and has to remain underground. 7在Which of the following strategies for oil exploration is described in paragraph 4 and paragraph 5? ○Drilling under the ocean’s surface ○Limiting drilling to accessible locations ○Using highly sophisticated drilling equipment ○Constructing technologically advanced drilling platforms 8在What does the development of the Alaskan oil field mentioned in paragraph 4 demonstrate? ○More oil is extracted from the sea than from land.
○Drilling for oil requires major financial investments.
○The global demand for oil has increased over the years.
○The North Slope of Alaska has substantial amounts of oil.
