　　我的问题

　　the first of Britain’s national museums

　　Britain’s first national museums

　　请问以上2句的区别是什么?是部分和整体强调的区别吗?

　　PumpkinMM的解释：

　　1. the first of Britain’s national museums 英国的第一批国家博物馆(肯定没有"世界第一的意思")

　　2. Britain’s first national museums 英国的, 第一批的, 国家博物馆 (有歧义: 两种理解: 英国的第一批国家博物馆, 英国的,第一批,国家博物馆) 因为这里Britain&apos 和first都修饰national museums.

　　OG188. As a result of medical advances, many people that might at one time have died as children of such infections as diphtheria, pneumonia, or rheumatic fever now live well into old age.

　　(A) that might at one time have died as children

　　(B) who might once have died in childhood

　　(C) that as children might once have died

　　(D) who in childhood might have at one time died

　　(E) who, when they were children, might at one time have died

　　B, the best choice, uses the prerred relative pronoun, who, to rer to many people. It observes formal and logical parallelism in the wording of the relative clause and the main clause: first, adverbs (once and now)&apos, second, verbs (might have died and live); and third, adverbial prepositional phrases (in childhood and into old age). A and C use the questionable relative pronoun that to rer to many people. They also violate the parallel structure noted above. D and E, although they use the correct pronoun, who, offer convoluted and nonparallel structures for the relative clause

　　原因状语的顺序：

　　Young female ballet dancers and gymnasts sometimes fail to maintain good eating habits caused by the desire to be as thin as possible.

　　(A) Young female ballet dancers and gymnasts sometimes fail to maintain good eating habits caused by the desire to be as thin as possible.

　　(B) Good eating habits sometimes fail to be maintained by young female ballet dancers and gymnasts caused by desiring to be as thin as possible.

　　(C) Because they desire to be as thin as possible, good eating habits are sometimes not maintained by young female ballet dancers and gymnasts.

　　(D) Because they desire to be as thin as possible, young female ballet dancers and gymnasts sometimes fail to maintain good eating habits. (D)

　　(E) Young female ballet dancers and gymnasts sometimes fail to maintain good eating habits because they desire to be as thin as possible.

　　告诉你,先原因,后结果,表达的意思清晰明确

　　weiyu的解释：

　　睡了一晚上。想出点ETS的思路供大家来批。

　　I do not think A, because B... ETS要我们翻译成认为A不是因为B;即逻辑中的A->~B, 是个逆否命题，强调结论。

　　上句话也可以是：B->~A就是原命题的逻辑;

　　所以当原因状语主从句表达否定意思时，because在后是逆否命题，强调结果。because在前是原命题，强调原因。

　　但是表示肯定意思时，就不大清楚了。因为英语和中文的意思是一样的。

　　Tianwan的解释：

　　I do not think A, because B 的意思只有：因为B，所以不认为A(I don&apost think A and the reason is B)

　　I do not think A because B的意思可能是：因为B，所以不认为A (I don&apost think A and the reason is B)or 不是因为B才认为A(I think A and the reason is not B)，一般取后者。

　　逗号很关键,没有逗号会引起歧义，书面语中一般取后者，口语中根据重音决定。

　　结论：because的优选结构是because A, B和B, because A; 不用B because A(强调歧意)

　　Jnlvo的解释：

　　不愧为逻辑区的版主。我感觉这么说是有些道理，不过最好还有更多的例子来说明佐证，否则还是有点抽象。

　　这题我没想到这么深，选的依据主要是选最常见的，最不可能产生歧义的选项。就如doing sth. ，sb+谓语和sb.，doing sth，谓语，如果其它看不出什么不同，只是doing的位置不同，我就选前者，因为这最常用，最不容易错。

　　Dreadpower的解释

　　讨论这个题目之前。我一直是这么认为的，ETS要求一定的逻辑表述，先发生的，先决的要先写，记得OG中有道两个分词在句首并列的那题提到过这点所以，我觉得在D，E都可的情况下，选D比较规范化。
