问题 The author refers to the ocean bottom as a "frontier" in Paragraph 1 because it ______.
Which of the following is true of the Glomar Challenger?
选项 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.
答案D
解析 由题干中的the Glomar Challenger定位到原文第二段第二句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 extracting samples of sediments and rock from the ocean floor．[精析] 推理判断题[考频：66]。原文第二段讲述了对海底进行第一次探索的情况。对海底首次进行探索始于 1968年的深海钻井工程，而在这一工程中发挥了主要作用的正是Glomar Challenger，它能在海平面上保持稳定并且能够钻入深水中，从而抽取样本。故D)正确。[避错] 将题干中的每一项都一一与第二段的内容对号入座。A)“它是一个潜水艇”，文中说它是drill ship(钻井船)，故排除A)；B)“它是一个正在进行的项目”，由原文可知它能钻入深水中，所以应是某种器械或工具，排除 B)，另外此处也不符合下段首句内容The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983；由第三段首句得知，Gloman挑战号完成96次航行，而不是“100多次”，故C)数字不符合，排除C)
