12-12: After graduating from high school, people rarely multiply fractions or discuss ancient Rome, but they are confronted daily with decisions relating to home economics. Yet whereas mathematics and history are required courses in the high school curriculum, home economics is only an elective, and few students choose to take it. Which of the following positions would be best supported by the considerations above? (A) If mathematics and history were not required courses, few students would choose to take them. (C) If it is important to teach high school students subjects that relate to decisions that will confront them in their daily lives, then home economics should be made an important part of the high school curriculum. 答案是C, 但是我觉得A 有道理. 我觉得argument说了数学和历史在日常生活中根本很少用 econ在daily life中经常涉及,但是因为是选修课,所以学生很少选==> 因为是选修课, 所以才没有很多人去选, 尽管很实用. 所以我觉得学校对课程做不做必修要求才是导致学生选课多少的依据. 看上去A 很不错啊! 同理: 要是数学和历史不做必修要求, 才不会有那么多人选呢. (想想啊, 连和生活那么有关的econ,只要是选修课都少人问津,更别说数学和历史了) C, 我无法将其和argument里面的逻辑推理过程联系起来. 大全-13-15 15. In Swartkans territory, archaeologists discovered charred bone fragments dating back 1 million years. Analysis of the fragments, which came from a variety of animals, showed that they had been heated to temperatures no higher than those produced in experimental campfires made from branches of white stinkwood, the most common tree around Swartkans. Which of the following, if true, would, together with the information above, provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids? (A) The white stinkwood tree is used for building material by the present-day inhabitants of Swartkans. (B) Forest fires can heat wood to a range of temperatures that occur in campfires. (C) The bone fragments were fitted together by the archaeologists to form the complete skeletons of several animals. (D) Apart from the Swartkans discovery, there is reliable evidence that early hominids used fire as many as 500 thousand years ago.（E） (E) The bone fragments were found in several distinct layers of limestone that contained primitive cutting tools known to have been used by early hominids. 我搞不懂为什么是E.不是cutting tools 不见得就证明用过火啊. 可以做家具,盖房.... |
