以下是引用mosww在2007/8/24 23:20:00的发言：

我觉得我们分析的太多了，老美其实已经把答案告诉我们了

In the United States, of the people who moved from one state to another when they retired, 定语前置
    the percentage who retired to Florida has decreased by three percentage points  over the past ten years. 

the percentage＝      the peple retired to Florida      

                            The people who moved from one state to another last ten years

D。The total number of people who retired and moved to another state
        for their retirement has increased significantly over the past ten years.
       

所以percentage的下降是由于分母上升引起的（它因），不是分子下降（去F的人减少）引起的，所以F不一定下降，结论不成立

不觉得题目出得非常严谨吗？这样一看别的选项根本就不可能选

不说什么了 顶顶顶~~~

难道我是个异类吗，为什么我觉得没有正确答案？？？！！！！
In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years.  Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses.
Which of the following, if true, most seriously weakens the argument?
A.    Florida attracts more people who move from one state to another when they retire than does any other state.
B.    The number of people who move out of Florida to accept employment in other states has increased over the past ten years.
C.    There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.
D.    The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
E.    The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago.

A.说的是F比其他任何周流入的人都多。但是并不代表F和自身比人数上升，举个例子，总共10个州，每个州都流入5个人到F，同时F向每个州流入1人。这个假设满足A的条件，但是对于F而言，退休人员反而减少了。支持了题目的观点

B. 太明显不解释

C.观点讨论的是和退休有关的业务，引入旅游业没有意义

D.说的是迁移到其他州的退休人员总人数增加了。但是不代表迁移到F州的人数增加了，有可能是减少啊

E.退休时离开F的人增多了，那是支持了观点啊

我认为此题无解！！！！

同意选D，D表达的是总人数的增加，只有总人数增加才能推出实际人数的增加从而weaken结论，E选项说的是从F搬走的人数的增加，如果总人数不变或减少，搬走的人变多，只会strengthen结论
