都是归纳里面的题,我做weaken还挺顺的,怎么到了归纳就转不过弯来了呢?还请各位赐教 1. Recent estimates predict that between 1992 and 1995 the greatest increase in the number of people employed will be in the catagory of low-paying service occupations. This category, however, will not increase its share of total employment, whereas the category of high-paying service occupations will increase its share. If the estimates above are accurate, which of the following conclusions can be drawn? A. In 1992 more people were working in low-paying service occupations than were working in high-paying occupations. B. In 1995 more peoplewill be working in high-paying service occupations than will be working in low-paying service. C Nonserice occupations will account for the same share of total employment in 1995 as in 1982. D.Many of the people who were working in low-paying service occupations in 1982 will be working in the -paying service occupations by 1995 E. The rate of growth for low-paying service occupations will be greater than the overall rate of employment growth between 1982 than 1995. 这道题答案选了A 我是比较了半天也没选出来。 提示说要用数学的方法进行比较。麻烦大家帮我看看哈 2. A recent survey of all auto accident victims in Dole Country found that, of the severely injures drivers and front-seat passengers, 80 percent were not wearing seat belt at the time of their accident. This indicates that, by wearing seat belts, drivers and front-seat passengers can greatly reduce their risk of being severly injured if they are in an auto accident. The conclusion above is not properly drawn unless which of the following is true(纠结在这里了一开始 是问那个可以支持上的结论对吧?) A Of all the drivers and front-seat passengers in the survey, more than 20 percent were wearing seat belts at the time of their accident B. Considerably more than 20 percent of drivers and front-seat passengers in Dole Country always wear seat belt when traveling by car. C. More than half of the drivers and front-seat passengers in the survey were not wearing seat belts at the time of their accidents. 剩下的两个选项明显不对 就没打上来。 这道题答案选A 我选的C。 我认为归纳就是不能超过原文的范围。所以原文说80% 我这里说half 就应该没有错。 难道这个more than half of 里面有玄机? 请大家指教 |
