大全 254，267,268，285 集中问了，谢谢！

254．Dr. Sayre’s lecture recounted several little-known episodes in the relations between nations that illustrates what is wrong with alliances and treaties that do not have popular support.

(A) relations between nations that illustrates

(B) relation of one nation with another that illustrates

(C) relations between nations that illustrate

(D) relation of one nation with another and illustrate（B）

(E) relations of nations that illustrates

答案E

在relation of one nation with another that中，不必忧虑读者搞不清that修饰relation还是another吗？记得 A of B, which结构中which既可以修饰A也可以修饰B。A of B that是否有同样问题？

267.       During the nineteenth century Emily Eden and Fanny Parks journeyed throughout India, sketching and keeping journals forming the basis of news reports about the princely states where they had visited.

(A) forming the basis of news reports about the princely states where they had

(B) that were forming the basis of news reports about the princely states

(C) to form the basis of news reports about the princely states which they have

(D) which had formed the basis of news reports about the princely states where they had

(E) that formed the basis of news reports about the princely states they

In choice A it is not immediately clear whether forming modifies journals or parallels sketching and keeping. Also, where they had visited is wordy and inappropriate for a simple reference to past events. Choice B does not establish who visited the princely states, and that were forming should be that formed. Choice C is unclear because to form could be read as either in order to form or so as to form, and the present perfect have visited does not agree with the past tense journeyed. In choice D, as in choice a, where they had is faulty, and had formed suggests that the journals and news reports existed before the journey. E is best for this question of average difficulty.

“主句, doing1 +名词+doing2/done”, 这里doing2/done可认为即能修饰主句，又能修饰前面的名词。这种结构要尽量避免，除非根据逻辑关系，明显不会产生歧义，则可被接受，参见大全877的armed的用法。

看了以上中英两种“大全注释”，有点糊涂了。说说我的理解A不好的原因是forming既可以sketching and keeping journals这个行为，又可以修饰journals，对吗？

268．During the recession of 1973, home mortgage foreclosures resulted in tens of thousands of Americans being evicted from homes that they can no longer afford monthly payments.

(A) that they can

(B) that they could

(C) on which they can

(D) because they can（E）

(E) for which they could

答案E

D为什么不对，一定要用could吗？

285．Even though the state has spent ten years and seven million dollars planning a reservoir along the Ubi River, the project will have to be abandoned as a result of the river becoming so heavily polluted.

(A) will have to be abandoned as a result of the river becoming so heavily polluted

(B) is to be abandoned on account of the heavy pollution which the river received

(C) had to be abandoned because the river had received such heavy pollution

(D) has to be abandoned because of the river and its heavy pollution（E）

(E) must be abandoned because the river has become so heavily polluted

答案： E

倒是没作错，不过看了N遍才敢选，因为感觉must和have to还不太一样，感觉have to好一点，另外新东方老师说must等情态动词不能随便加减。只是觉得前4个选项硬伤太大。大家觉得E这样改合适吗？？？

楼主还是分开贴比较好，这样便于大家回帖讨论和查询。

254. 是可能存在这样的问题，到底修是A或B，我觉得一是看主谓一致，二是直接从意思判断，当然最主要的纵向比较，能有更好的表达方式，来避免这种歧义最好。这题有过争议，论坛中有部分人认为是C。我自己很难判断。最好能看到ETS做的注解。

267，og说forming 即可modifies journals 或是 parallels sketching and keeping，产生了歧义。

268，can和could在这里倒不是主要区别，主要从意思看。result in和because重复，D的意思表达不好。

E用了定语从句，payments for sth., to pay for sth.的名词表达形式。

285. 这题must和have to 区别倒还不是主要问题, 如你所言前4个都有大硬伤，所以当然是E。新东方所言不错，但事情多是相对的，不能太教条。
