1.A recent poll found that over 80 percent of the residents of Nalmed Province favored a massive expansion of the commuter rail system as a means of significantly easing congestion on the province’s highways and were willing to help pay for the expansion through an increase in their taxes. Nevertheless, the poll results indicate that expansion of the rail system, if successfully completed, would be unlikely to achieve its goal of easing congestion, because       .
          A.    most of people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience.
          B.    of the less than 20 percent of residents not counted as favoring the expansion, about half claimed to have no opinion one way or the other.
         C.    the twice-daily periods of peak congestion caused by people commuting in cars have grown from about an hour each to almost two and a half hours each in the past 20 years.
         D.    expanding the commuter rail system will require the construction of dozens of miles of new railroads.
         E.    the proposed expansion to the commuter rail system will make it possible for some people who both live and work at suburban locations to commute by rail.

答案是A，不知道是怎么解释的？？

2.Although the number of large artificial satellites orbiting the Earth is small compared to the number of small pieces of debris in orbit, the large satellites interfere more seriously with telescope observations because of the strong reflections they produce. Because many of those large satellites have ceased to function, the proposal recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since     .

A.    the only way to make telescope observations without any interference from debris in orbit is to use telescopes launched into extremely high orbits around the Earth
B.    a greatly increased number of small particles in Earth’s orbit would result in a blanket of reflections that would make certain valuable telescope observations impossible

答案是B，个人认为AB均可呀，A说该手段无法达到目的不也能让它ill conceived吗？？想不通啊……！

第二道题目

题目问的是 要通过爆炸的方法去消除那些大卫星，然后找到这个 proposal 的漏洞

A - 和这个proposal 没有关系
B - 爆炸后，会产生更多的小碎片，然后也会有问题了

第一题A我是这么理解的 那些愿意expand railway 的人之所以愿意交钱是因为觉得修了铁路以后公路交通压力会降低，也就是说，即便铁路修好了，这帮人也不会换成railway上下班，还是想开车，所以congestion不会缓解

第二题 A 楼主啊 不要想太多啊 没关系的 重点是这个proposal为什么不对，不是要提个新的

第一题同问一下，觉得楼上说得有道理：A 里面说的那些人是想rail way 好了后，别人会坐rail way这样他们上班就不会那么congestion...如果人人都这样想，等别人去做rail way那这个效果是达不到的。。。。。真bug.....

那么，如果是这帮人支持修铁路，反而不乘铁路，那么为什么要report less congestion呢？应该是report more吧。我认为,report less使得建设铁路的部门对铁路投入不足，从而不足以缓解高速公路的压力。比如，report less，只投入两班次列车，但实际上需要10班次每天，所以8班次的不足就是由于report less造成的，其实就是使铁路部门低估高速路的压力，从而投入不足。
不知道对不对，请批评指正。

这道题百思不得其解啊，哪位高手能翻译一下A吗

第二题，不能随便说一个原因的，给出的原因要跟作者推导的“因”（explode）和“果”（ eliminate interference ）有关

第2题我也选了A，总觉得B的答案需要先说明：explosion会产生a greatly increased number of small particles。
或者说这个说明是常识？？？

explosion产生small paretic应该是很明显的常识了，不需要明确地写出来了。要关注结论，最后一句话since前面说this proposal is ill conceived，所以要解释的是this proposal，要说出this proposal的问题
