易错题解析：
Paragraph 2：Continued sedimentation—the process of deposits' settling on the sea bottom—buries the organic matter and subjects it to higher temperatures and pressures, which convert the organic matter to oil and gas. As muddy sediments are pressed together, the gas and small droplets of oil may be squeezed out of the mud and may move into sandy layers nearby. Over long periods of time (millions of years), accumulations of gas and oil can collect in the sandy layers. Both oil and gas are less dense than water, so they generally tend to rise upward through water-saturated rock and sediment.
4.Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
○Higher temperatures and pressures promote sedimentation, which is responsible for petroleum formation.
○Deposits of sediments on top of organic matter increase the temperature of and pressure on the matter.
○Increase pressure and heat from the weight of the sediment turn the organic remains into petroleum.
○The remains of microscopic organisms transform into petroleum once they are buried under mud.
题型：句子简化题。答案是(C)
解析：原句主干为：Continued sedimentation buries the organic matter and subjects it to higher temperatures and pressures. 破折号之间的the process of deposits' settling on the sea bottom作为continued sedimentation的同位语，进一步解释说明的作用; which convert the organic matter to oil and gas是定语从句，修饰前面这个主句。原句的意思是：持续的沉积——堆积物沉积到海底的过程将有机物埋在海底使之受到海底温度、高压的影响，最终转变成油和气体。C表述准确而且全面，所以是正确选项。B表述正确，但是遗漏了重要信息，也就是最终的结果：转变成石油天然气。A和D原文中都未提及。
语法点：插入语的用法。
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.
10.According to paragraph 5, the decision to drill for oil depends on all of the following factors EXCEPT
○permission to access the area where oil has been found
○the availability of sufficient quantities of oil in a pool
○the location of the market in relation to the drilling site
○the political situation in the region where drilling would occur
题型：否定事实信息题。答案是(D)
解析：结合题干和选项到原文一一定位，
A对应第三句“Some oil lies under regions where drilling is forbidden, such as national parks or other public lands. ”，正确，不选;
B对应倒数第二句“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. ”正确，不选;
C项对应第二句，“It may be in a pool too small or too far from a potential market to justify the expense of drilling.”正确，不选;
D项原文没说，即为本题的答案。
语法点：even引导的让步状语从句的用法。
