题文

The ocean bottom，a region nearly 2.5 times greater than the total land area of the Earth， is even today largely unexplored. Until about a century ago，the deep-ocean floor was completely inaccessible and hidden beneath waters averaging over 3，600 meters deep. Total­ly without light and subjected to inten pressures hundreds of times greater than at the Earth's surface，the deep-ocean bottom is a strange environment to humans，in some ways as forbidding and remote as the outer space. Although rearchers have taken samples of deep-ocean rocks for over a century，the first detailed global study of the ocean bottom did not actually start until 1968，with the beginning of the National Science Foundation's Deep Sea Drilling Project ( DSDP). Using techniques first developed for the offshore oil and gas industry，the DSDP's drill ship，the Glomar Challenger，was able to maintain a steady position on the ocean's surface and drill in very deep waters，taking samples of rock from the ocean floor. The Glomar Challenger completed 96 voyages in a 15-year-rearch program that ended in November 1983. During this time，it sailed 600，000 kilometers and took almost 20，000samples of rocks around the world. Tho samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to make out what it will probably look like millions of years in the future. Today，largely on the strength of evidence gathered during the Glomar Challenger's voyages，nearly all earth scientists agree on the theories of plate tectonics (构造学) and continental drift that explains many of the geological process. The samples of rocks drilled by the Glomar Challenger have also provided a climatic re­cord stretching back hundreds of millions of years. The information of past climatic changes can be ud to predict future climates. 小题1:The underlined word" inaccessible" in Line 3 means . A．unrecognizable B．unreachableC．unusable D．unreasonable小题2:Why does the author mention "outer space" in the first paragraph? A．The Earth's climate millions of years ago was similar to that in outer space. B．It is similar to the ocean floor in being strange to the humans. C．Rock formations in outer space are similar to tho found on the ocean floor. D．Techniques ud by scientists to explore outer space were similar to tho ud in ocean exploration.小题3:Which of the following is TRUE of the Glomar Challenger? A．It is a type of submarine. B．It is an ongoing project. C．It has gone on over 100 voyages. D．It made its first DSDP voyage in 1968.小题4:The Deep Sea Drilling Project was significant becau it was .A．an attempt to find new sources of oil and gas B．the first extensive exploration of the ocean bottom C．made up of geologists from all over the world D．supported entirely by the gas and oil industry小题5:Which is NOT mentioned in the passage as being a result of the Deep Sea Drilling Project? A．Geologists were able to determine the Earth's appearance millions of years ago. B．Two geological theories became more widely accepted by scientists. C．Geologists obrved forms of life never before en. D．Information was revealed about the Earth's past climatic changes. 题型：未知难度：其他题型

考点

据考高分专家说，试题“The ocean bottom，a r.....”主要考查你对 [日常生活类阅读 ]考点的理解。 日常生活类阅读

日常生活类阅读的概念：

日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。

日常生活类阅读题答题技巧：

【题型说明】该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。 【备考提醒】为了保证较高准确率，建议同学们做好以下几点： 1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。 2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。 3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。 4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
