标题: 几道没有标准答案的真题，大家帮忙看看吧。十分没有把握。
19: Sonya: The government of Copeland is raising the cigarette tax. Copeland’s cigarette prices will still be reasonably low, so cigarette consumption will probably not be affected much. Consequently, government revenue from the tax will increase.

Raoul: True, smoking is unlikely to decrease, because Copeland’s cigarette prices will still not be high. They will, however, no longer be the lowest in the region, so we might begin to see substantial illegal sales of smuggled cigarettes in Copeland.

Raoul responds to Sonya’s argument by doing which of the following?

A: Questioning the support for Sonya’s conclusion by distinguishing carefully between No change and no decrease

B: calling Sonya’s conclusion into question by pointing to a possible effect of a certain change.

C: Arguing that Sonya’s conclusion would be better supported if Sonya could cite a precedent for what she predicts will happen.

D: showing that a cause that Sonya claims will be producing a certain effect is not the only cause that could produce that effect

E: pointing out that a certain initiative is not bold enough to have the predicts it will have

16: In recent years, networks of fiber-optic cable have been replacing electrical wire for transmitting telecommunications signals. Signals running through fiber-optic cables deteriorate, and so the signals must be run through a piece of equipment called a regenerator before being transmitted father. Light-Line is the leading manufacturer of signal regenerators. Therefore, Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed.

Which of the following, if true, casts the most doubt on the prediction about light-ling’s prospects?

A: Telecommunications signals sent along electrical wires can travel much farther than signals transmitted through fiber-optic before needing to be regenerated.

B: Expanding its production of regenerators will require Light-line to spend proportionately more on labor and materials.

C: The volume of signals that a fiber-optic cable can carry is several thousand times greater than the volume that can be carried by an electrical wire of similar size.

D: There are technologies that enable telecommunications signals to be transmitted without either wire or fiber-optic cable.

E: Several manufacturers are developing regenerator technologies that will allow signals to be transmitted many times farther than at present before requiring regeneration.

28-28: Which of the following most logically completes the argument?

A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert. Possibly, therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils, a hypothesis that would gain support if ______.

A: histidine is found in all parts of the plant – roots, stem, leaves, and flowers

B: the herb’s high level of histidine production is found to be associated with an unusually low level of production of other amino acids

C: others of the closely related group of plants are also found to produce histidine in large quantities

D: cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic

E: the concentration of histidine in the growing herb declines as the plant approaches maturity

我的答案：a e c

选d,有一个逻辑错误:题目说那个herb能产生一种东东,让毒素失效.可是他没说那个东东释放到了外面土壤里啊,很可能它就只停留在植物体内发挥作用啊,很多生长素就是这样的,所以也不会对土壤产生影响.

c我觉得是很好的加强啊,一种herb有了histidine,就能帮助它生存,那么其他也能生存的植物也都有那个东东,直接加强结论啊.

看来大家都认为第2题是E，但其实应该是D。我本人就是搞电信的。

大家再仔细想想

刚刚想了一下，考虑到题干是LONG DISTANCT FIBER-OPTIC TELECOM NETWORK，看来还是E对。我本来的想法有点问题。

第一题分析的是政府加税跟政府收入的关系，sonya认为加税不会使香烟的售价高到影响消费的程度，因此只要消费不降，政府的收入就会因加税而增加。但R指出另一种可能：即加税导致的价格升高会使一部分消费者购买走私烟，即实际上加了税之后的正路的香烟的购买量会减少，从而有可能导致政府的收入下降。（注意:只是有可能）这样R就提出另外的一种可能性。B似乎是正确答案。

第二题：争议只在D与E，E说明生产商在研制新的regenerator,比原来的更好。但依然是用regenerator技术，而light-line就是主要的生产商，surely it can develope similar regerators，并不对结论构成攻击。而D提出新的技术不用光纤传递，that will directly put light-line out of business,因此选D。

此题的关键在于：作者认为regenerator这种技术的运用会导致该产品的主要厂商发达。所以最有力的攻击是如果新技术淘汰了regererator，那么light-line的日子还会好过吗？

第三题是个性与共性的关系。is one of a group of closely related plants that thrive in soil ...说明这一类plants都可以在这样的土壤里生长。而Agronomists只研究了这一类中的一种，发现histidine含量高，那么，如果这一类都是histidine含量高，不就充分证明了这类plant能够在这种土壤中存活的原因吗？所以应该选C

关于16题

请注意结论的特殊性：if new long-distance fiber-optic telecommunications networks are constructed. 也即要建的是有 fiber-optic 的网络，没有 fiber-optic 的情况全部是无关选项。所以D错。对于E。regenerators是解决信号衰减的问题，尔该公司垄断了regenerators的生产，如果如E所说，信号问题解决了，就不需要regenerators，该公司能否从建网络中得益就会受到怀疑，所以为答案。

多谢lawyer，看题的时候漏看了if new ....这段，的确，有了这句就限定了讨论的范围，答案D变成了out of scope。

看来还是得仔细。

呵呵，楼上JEFFZHU和我开始时犯的错误一样，都漏看了题干中已经规定了范围。

这题还是E对。

以下是引用jeffzhu在2005-7-17 13:35:00的发言：

28-28: Which of the following most logically completes the argument?

C: others of the closely related group of plants are also found to produce histidine in large quantities

D: cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic

其他plant有histidine不能加强结论，因为没有说其他plant能存活是由什么导致的，所以C错

我觉得D是有因有果、无因无果的加强方式，有histidine --> 能存活，无histidine --> 不能存活，所以加强结论
