几道黄金高频JJ里的题，还有三天考试，麻烦大家帮忙～

I'm have different opinion about question 3

I vote for B since we have to find a choice to support the conclusion that the scan can be used to decrease the rate of unnecessary surgery but not decrease the rate of necessary surgery.In choice B,all of the necessary surgery will be performed by surgeons without omitting. Misdiagnoses is always standing since 2% of miisdiagnoses is a part of the test.

So ,B is the answer from my point of view.

the last one

I will pick A

that says people support the plan used the highway when it is not congested.That means these people are not the part of congestion.They are not the reason to cause the traffic problem.So even though the road expanded ,they will contribut nothing to the easing congestion and those who met congestion in the past will still drive their cars onto the highway and easing congestion will be weaken definitely.

so  crazy~~~~~~

i am confused

but i will still try to find the correct answers and justify them 

最终确定答案了．．．第３个是b，第四个是c．．．

第四题的e实际上与结论相反的．．而我所考虑的样本选择的问题在e上没有表现出来．．．．

c选项是说堵塞情况更加严重即使是扩展了也不能解决问题．．．．

......

c

??:个人认为这题没有写出正确答案.assumption应该是: "respected nonpartisan auditors are nuetral" 或者类似的才能支持结论.而b反而会weaken结论,因为指出被取消的大都不是总统所在党管的.---说明总统是partisan

b,只有把非阑尾炎当成阑尾炎治的情况下,才会出现arguement中'without performing fewer necessary .....",有点像"宁可错杀一千,不可漏掉一个"的政策.

a 那些支持建铁路的人说他们期望建成后公路交通的改观会是他们的最大受益点,说明那些支持建铁路的人会在铁路建成后走公路.所以A说明交通不会改观.其它的答案好象都不是太合适.

HEHE....请NN们多指教.

谢谢大家哦～

其它的题都弄懂了，就是最后一个，还是有点争议。

我看了大家的解释觉得A对，可是我还是没有知道为什么E不行呢？

还有itokinblue选C，我觉得有点疑问呢

the last question isn't a good and typical question,

A. most people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience

- that means people who in favour of the program of expansion will use the highway after it compelte.

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

- nothing related to the question.

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

- so what?In the past the situtation is not that good ,how about that happens when the expension is compeleted?There is no reason to negate the positive resluts.

 D expanding the commuter rail system will require the construction of dozens of miles of new railed

- out of scope.The question need us to find out why the congestion won't be eased even though the railway is expended. What is required by the construction is nothing to this question.

E the proposed expansion to commuter rail system will make it possible for some people who both live and work at suburban locations to commute by rail.

- So what?If more people will use rail ,how to soundly say that this expension program will fail in the end?

So I thought A is the answer and open to disscuss...

恩是选A 谢谢哈
