排除法
A错在于我们不能从第一个划线部分推出第贰个划线作为结论.(the second is a conclusion that can be drawn from the first)the key word laid on'drawn from the first'
B is not right for we can not firmly decide that the conclusion must be draw from the
argument.it is highly possible that other factor will ocur which will rot the basis to be sufficient to support the conclusion.
and as for  c,it is read the first acknowledge a consideratoin that support the main positoin,and the point is we can not kown what is the main position.
I PREFER choice d
concerning choice e,we should distinguish the evidence from the principle.AS FAR AS
I KOWN,THE PRINCIPLE SHOULD REFER TO SOMETHING LIKE'IF.............THEN.......'SO THAT THE EVIDENCE THAT FOLLOW IT,COULD DEPEND.

我同意miejue,选D.因为"论据"可以是多种多样的,包括事实论据,原理或原则.既然"论据"的意义更广,那么evidence 应该比fact和 principle的正确性都高.另外B还错在不该用"必须",因为结论不是能够必然推出的,而只是可能推出的,论证中所有的证据都不能排除有他因可以解释结论"偏航"的可能性.

以下是引用vrylwj在2003-9-5 12:16:00的发言：
哪位解释一下，为什么都选　E　不选　D　呢。

D is a evidence  which could be subjective or objective.
Evidence is "A thing or things helpful in forming a conclusion or judgment"
but E is a principle which is a fact or which is objective
Principle is "A basic truth, law, or assumption"
Big difference.

i can't agree with answer "E"

the second is a conclusion, but this conclusion can not be drawn from the argument

i choose D, the first is an evidence supporting the second

1。老式得飞机也用同样得方式降落。不能完全支持结论。只能作为前提。

答案在哪里？

In my opinion, the first only provides a general principle stating the role of the navigation system, which might be interfered or not be interfered.

the first can not support the second --the conclusion of the argument-- which indicates that the navigation system made in low-power circuitry is interfered.

so ,I choose E

1.前提：新导航系统由低电压电路构成，低电压电路比真空管电路更容易受到干扰

2.前提：在着陆的时候，导航系统接收机场电波信号，不让飞机偏离跑道

3.事实：一架带低电压电路的飞机（低电压电路不等于新导航系统）在着陆的时候偏航，飞机仪表盘变得模糊，此时有人打开笔记本电脑。

4.结论：乘客携带电子设备（笔记本电脑等）将威胁新导航系统的安全

仅从条件3，我们只能得出：乘客的电子设备会干扰低电压电路的正常工作，并且会影响导航系统（是新导航系统还是旧导航系统我们无从得知）。

但是1+3告诉我们：乘客的电子设备会干扰新导航系统的正常工作（因为新导航系统就是由低电压电路构成的），这就是结论4。

乘客电子设备的对新导航系统的影响不应该只局限在着陆的时候，当飞机在空中的时候，乘客使用笔记本等电子设备同样会干扰导航系统的工作（本来要飞北京，结果飞到上海），2只是导航系统受影响的一个方面，故应当作为支持结论的证据之一。

此题应当选D

I picked C because:

1. The main position is that modern navigation systems are "more susceptible to interference than the vacuum-tube circuitry found in older planes."

2. The 1st bold statement gives an example that supports the main position.

3. The 2nd bold statement is the conclusion.
