其实这只是3、4自己完全不能理解答案的题目中的一道,如果不是答案错,我就。。。。
第21套题的第四篇
7. On turning 65 years old, everyone living in the town of Malton becomes eligible to receive a card that guarantees discounts on most goods and services sold in the town. Census records for 1990 show that 2, 450 inhabitants of Malton turned 64 in that year. Yet . in 1991 over 3,000 people applied for and properly received discount cards. So clearly some of Malton's population growth between 1990 and 1992 must be attributable to migration into the city by people in their mid -60's。
Which of the following is an assumption on which the argument depends?
(A) The town of Malton has no complete census records for 1991.
(B) The overall size of the population of Malton grew by over 500 during 1990.
(C) Fewer people applied for and received discount cards in 1991 than did so in 1992.
(D) Among the people 65 years old or older who moved into Malton in 1991. there was no one who did not apply for a discount card .
(E) In general. people who applied for and received discount cards in 1991 first became eligible to do so in that year
我选的是E,答案是D。
我的想法是:90年的人口普查,只有2,450人到了64岁,不考虑流入,只有这么多人在91年开始具有资格,而1991年有3000多人申请卡片,那么1991年就有3000多人年龄至少在65岁。可能的原因就是两个,一个是移民增加了可申请卡片的人口数量,或者是,91年申请卡片的人中,有些人已经超过了65岁,只不过没有在正好65岁的时候申请卡片,当然两种可能可以并存。题目中的结论就是(很有可能是我对结论的理解不够精确,我的理解是)90到92年的一部分移民是年龄超过65岁的,也就对应前面的第一种可能。那么也就是说第二种可能比较不可能(这话说的。。。),也就是E选项中的 “大体来说,91年申请卡片的人第一次具备申请资格(刚到65岁,而不是在66、67.。。。时候申请)。话句话说,如果选项E不成立,那么就是说很多人在超过了65岁的情况下申请卡片,那么文中有关移民的论断就是不成立的。所以E是假设。
而我觉得D选项和结论完全无关。和上面一样,假设D不成立,那么也就是移民中超过65岁的人,有人没有申请卡片,但是这并不影响上面提及的任何两个可能,反而是,在有人没申请的情况下,仍然有over 3000 insteand of 2450的人申请,那么超过65岁的移民可能更多,D的不成立成了文中结论的支持。
另外就是对文中 from 1990 to 1992,不是很理解,为什么涉及到1992? 还有mid 60‘s 该如何理解呢? 65 66都算的?那64.67算不算?
写得有点乱,不过我真的紧张,感觉自己的逻辑和题目(至少是答案)对不上点。哪位好心指点一下吧。
不胜感谢。
