To wangsiwei: 你说的这道题应该是选C,对吗?
恩,同意楼上的。 其实不用像LZ想那么复杂。再说在考试的时候也没有时间考虑那么多。 这个题有点偷换概念。GAMT里常考。 就像下面的题 Automobile Dealer's Advertisement: The Highway Traffic Safety Institute reports that the PZ 1000 has the fewest injuries per accident of any car in its class. This shows that the PZ 1000 is one of the safest cars available today. Which of the following, if true, most seriously weakens the argument in the advertisement? (A) The Highway Traffic Safety Institute report listed many cars in other classes that had more injuries per accident than did the PZ 1000. (B) In recent years many more PZ 1000s have been sold than have any other kind of car in its class. (C) Cars in the class to which the PZ 1000 belongs are more likely to be involved in accidents than are other types of cars. (D) The difference between the number of injuries per accident for the PZ 1000 and that for other cars in its class is quite pronounced. (E) The Highway Traffic Safety Institute issues reports only once a year. 在题目里,会突然把B说成C,然后推出结论。assumption-就要把两者连桥,而如果weaken的话,就是断桥。 -- by 会员 wangsiwei (2010/7/29 1:10:10)
