例如: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.
此题作答时要将原文第一、二句话看全:“Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation 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” , 只有这样才能选出答案:(D)It made its first DSDP voyage in 1968.
又如:The Deep Sea Drilling Project was significant because it was
(A) an attempt to find new sources of oil and gas
(B) the first extensive exploration of the ocean bottom
(C) composed of geologists from all over the world
(D) funded entirely by the gas and oil industry
此题排在上面一题的后面,对应出处一般应在上面一题的对应句后面,但是它的答案却偏偏出现在上面一题的对应句前面:”Although researchers have taken samples of over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968,” 这就是典型的倒序现象。然而不难看出,此题的答案句与上面一题的答案句是重叠的,也就是说上面一题做出以后,这道题的答案句也就不言自明了。
