几题供讨论。

juan

1. According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is good for cardiac health.

B. wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be

C. wild animals have less total fat than that of livestock fed on grain and have more fat of a kind thought to be

D. total fat of wild animals is less than livestock fed on grain and they have more fat of a kind thought to be

E. total fat is less in wild animals than that of livestock fed on grain and more of their fat is of a kind they think is

请教正确答案.

把C中的that 看成指代fat行吗?

B中的have less fat than livestock会不会有歧异? 但感觉more of a kind of fat 比more fat of a kind好.

2. Section 301 of the 1988 Omnibus Trade and Competitiveness Act enables the United Trade Representative to single out a country as an unfair trader, begin trade negotiations with that country, and , if the negotiations do not conclude by the United States government’s being satisfied, to impose sanctions.

B.by the United States government’s satisfaction, impose

D.to the United States government’s satisfaction, impose

B还是D?

查了Longman: conclude

[intransitive always + adv/prep, transitive] to end something such as a meeting or speech by doing or saying one final thing
[+ with/on/as/by etc]: The session usually concludes with an informal discussion. | conclude sth: We were finally able to conclude the meeting and go home. | conclude sth with/by etc: The service was concluded with a hymn.

但好象to one’s satisfaction 也是idiomatic的.

3. Gas hydrates, chemical compounds of water and natural gas, are increasingly being studied for their potential to be huge reservoirs of energy, possibly causing sea floor instability, and significant contributors to global warming.

B. to be huge reservoirs of energy, possibly casuing sea floor instability, and even as

C. as huge reservoirs of energy, possibly casuing sea floor instability, and

D. as huge reservoirs of energy, and the possible casue of sea floor instability

E. as huge reservoirs of energy, as possible casues of sea floor instability, and even as

请教正确答案.

Thanks in advance.

第一题我倾向于C；A中they缺乏指代；B中比较对象模糊(如你所言，我认为有歧义)，more of a kind of fat表达不好，而more fat of a kind表达准确；C中的that就是指代fat，而且只能指代fat；D/E的主语表达不好，且D比较对象错，E比较对象的介词结构不平行，their/they缺乏指代。

第二题选D，to sb's satisfaction是习语。

第三题选E，结构平行。

第三题E结构是平行。可have the potential as possible causes of sea floor instability, and as contributer of global warming逻辑上对吗？

第二题：可是conclude sth. with/by sth.也是习语呀。

第一题：我对B中的wild animals have less total fat than livestock是不是歧义很困惑----以前看大牛讨论过比较歧义的问题，说如果从逻辑意思上考虑也是判别歧义的一个方法。如果逻辑上明显不可能会产生误解的，也叫做不会歧义。比如 Jack has more apple than Mike.肯定不会被认为是Jack 有更多的apple超过有更多的Mike.所以这句子认为不会引起歧义。那么这题呢？从逻辑上是不是很清楚地肯定不会让人理解成“wild animals 有更少的fat，而不会有更少的livestock”呢？如果逻辑上肯定不可能产生这种误解的话，那么B是不是就可以看成不可能引起歧义了？

C让我感觉好象是wild animals在和that of livestock比。so weird。要是wild animals have less fat than do livestocks就清楚了。可是没有这么容易的选项。

1. According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is good for cardiac health.

B. wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be

C. wild animals have less total fat than that of livestock fed on grain and have more fat of a kind thought to be

D. total fat of wild animals is less than livestock fed on grain and they have more fat of a kind thought to be

E. total fat is less in wild animals than that of livestock fed on grain and more of their fat is of a kind they think is

A，B： "fed on grain and more of a kind of fat"并列歧义

D: than前后不对称

C,E看上去都挺像答案，但E里用了"their""they"怕是有问题，C的"have less total fat than that of livestock "不知这种比较形式是否可以？NN指点。

2. Section 301 of the 1988 Omnibus Trade and Competitiveness Act enables the United Trade Representative to single out a country as an unfair trader, begin trade negotiations with that country, and , if the negotiations do not conclude by the United States government’s being satisfied, to impose sanctions.

B.by the United States government’s satisfaction, impose

D.to the United States government’s satisfaction, impose

B还是D? 有其他选项吗？D比B看着顺眼

3. Gas hydrates, chemical compounds of water and natural gas, are increasingly being studied for their potential to be huge reservoirs of energy, possibly causing sea floor instability, and significant contributors to global warming.

B. to be huge reservoirs of energy, possibly casuing sea floor instability, and even as

C. as huge reservoirs of energy, possibly casuing sea floor instability, and

D. as huge reservoirs of energy, and the possible casue of sea floor instability

E. as huge reservoirs of energy, as possible casues of sea floor instability, and even as

E正确。ABC里“casuing ”无法和前面联系：接“to be”或“as”文法不通，非限制修饰“reservoirs of energyenergy”逻辑不通；D和后面连不上

conclude的用法：conclude that,conclude by doing,one  concludes sth with another,conclude with sth.

所以conclude by sth错。

leeon

B. wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be

C. wild animals have less total fat than that of livestock fed on grain and have more fat of a kind thought to be

B变成了 more of a kind of fat thought to be health这里more是名词，而不是wild animals thought to be...；关于比较的对象我觉得还是一定要对等。这里补出that of，用that指代total fat使句意更清晰。

以下是引用juan在2004-7-21 12:40:00的发言：

第三题E结构是平行。可have the potential as possible causes of sea floor instability, and as contributer of global warming逻辑上对吗？

第二题：可是conclude sth. with/by sth.也是习语呀。

第一题：我对B中的wild animals have less total fat than livestock是不是歧义很困惑----以前看大牛讨论过比较歧义的问题，说如果从逻辑意思上考虑也是判别歧义的一个方法。如果逻辑上明显不可能会产生误解的，也叫做不会歧义。比如 Jack has more apple than Mike.肯定不会被认为是Jack 有更多的apple超过有更多的Mike.所以这句子认为不会引起歧义。那么这题呢？从逻辑上是不是很清楚地肯定不会让人理解成“wild animals 有更少的fat，而不会有更少的livestock”呢？如果逻辑上肯定不可能产生这种误解的话，那么B是不是就可以看成不可能引起歧义了？

C让我感觉好象是wild animals在和that of livestock比。so weird。要是wild animals have less fat than do livestocks就清楚了。可是没有这么容易的选项。

第一题的歧义问题我个人认为逻辑的排除其实是有前提的，即语法上可能有多种可行的方案供选，从中可以用逻辑排除法排除，但是B这种结构我认为比较对象就是不对等，在我的总结中发现，仅仅在比较的两个主语是相同的情况下，也即后面一个名词用that/those补出的时候，才可以不补出动词，其他比较主谓的情况下一律要补出动词。至于C正确与否，参考OG19中ETS最后的一句解释，可以有助于理解：

19. In addition to having more protein -than wheat does, the protein in rice is higher quality than that in wheat, with more of the amino acids essential to the human diet.

(E) rice has a protein higher in quality than

Choice E needs either that in or does after wheat to make a complete and logical comparison.

至于第三题的逻辑性我认为的确会造成答题困难，但是也不难想象，所有的东西都是be studied for their potential，而potential并不是一个褒义词而是一个中性词，可以理解为‘可能性’。

juan

都很清楚了。

谢谢大家的指点。
