GMATprep 中的几道题请教 - ChaseDream

1.Because she knew many of the leaders of colonial Amercia and the American Revolution personally,Mercy Otis Warren was continually at or near the center fo political events from 1765 to 1789 , a vantage point combining with her talent for writing to make her one of the most valuable historians of the era.

2. The success of the program to eradiate smallpox has stimulated experts to pursue what they had not previously considered possible-- better control , if not eradiation, of the other infections such as measles and yaws.

A.what they had not previously considered possible-- better control , if not eradiation, of the other infections such as

B. what they had not previously considered a possibility --better control , if not eradiation, fo such infections like

C. something they had not previously considered possible--better control , if not eradiation, of such infections as

D. something not considered a previous possibility--better control and perhaps eradiation, of other infections such as

E.the possibility fo what they had not previously considered--better control and possibly eradiation fo infections like

Because she knew many of the leaders of colonial Amercia and the American Revolution personally（从句）,Mercy Otis Warren was continually at or near the center fo political events from 1765 to 1789 （主句）, a vantage point combining with her talent for writing to make her one of the most valuable historians of the era.（做什么成分呢？）

同位语？那就得 a vantage point 就近修饰 1765 to 1789 ，意思又不对

独立主格？但是句子a vantage point（主语） combining with her talent for writing（分词修饰） to（为什么要加个to） make（动词） her one of the most valuable historians of the era.

或者是【a vantage point +分词修饰+to do sth 】做主语，但是后面没有谓语动词

what they had not previously considered possible-- better control , if not eradiation, of the other infections such as

OG38. Scientists have observed large concentrations of
heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the
growth of industrial activity there.
(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there（D）

我上课的时候老师讲过，findings consistent with the growth of industrial activity in the area 这里的findings 是对前面整个句子的概括，而且这一句里也没有谓语动词，我也说不清这是个什么结构，但是我觉得结构上没有错，只是读起来太长，而且没有强调出句子的中心，从语感上，我觉得E是要好一些，但是我还是找不到理由排除A。

非限制性定语从句，就近修饰sediments，但是意思不通
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings

its有问题，指代不清，似乎是避免重复的使用，但是意思变了
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area

sediments from the Baltic Sea表达明确，上面Baltic Sea sediments起码得有所有格。findings做名词，指代前面得“发现在。。。沉积物里得什么重金属浓度很高”
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there

consistent with the growth of industrial activity there直接连在逗号后，没有主语，则逻辑主语与主句主语一致，但是说不通意思

sb find what。。。。？除非是sb find 【what sb always looking for is。。。】

所以第二题得 what they had not previously considered a possibility --better control 要加is才通

where修饰sediments，错

(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area

此题正确答案中的findings consistent with the growth of industrial activity in the area和楼上的第一道PREP题里面A选项的a vantage point combining with her talent for writing to make...一样，都是名词短语，且都是对前面句子的一个概括，那为什么A不对呢？

Scientists have observed large concentrations of
heavy-metal deposits in the upper twenty centimeters of sediments from the Baltic Sea, findings（是指代得 large concentrations ） consistent with the growth of industrial activity in the area

2.Because she knew many of the leaders of colonial Amercia and the American Revolution personally,Mercy Otis Warren was continually at or near the center fo political events from 1765 to 1789（这里已经是一个句子） , a vantage point（这个名此能指代前面一句句子？一句句子就说了一个东西a vantage point？） combining with her talent for writing to make her one of the most valuable historians of the era.

79． Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments，which are consistent with the growth of industrial activity there.

(A) Baltic Sea sediments，which are consistent with the growth of industrial activity there

(B) Baltic Sea sediments，where the growth of industrial activity is consistent with these findings

(D) sediments from the Baltic Sea，findings consistent with the growth of industrial activity in the area

(E) sediments form the Baltic Sea．Consistent with the growth of industrial activity there

This ambiguous sentence can be clarified by asking a series of questions：The are in the upper twenty centimeters of what? Of the sediments, not of the Baltic Sea, so it is dearer to place sediments direly after centimeters．As the sentence is written，which seems to refer back to the whole previous clause．Substituting a noun，findings, makes the reference clear．Where has the growth of industrial activity taken place? There is too vague and makes it seem that the industry is taking place in the sediments．Replacing there with the more specific in the area solves this problem．

A Baltic Sea sediments is hard to understand；which has no logical referent；there is too vague.

D Correct．This sentence is logical and clear．Sediments from the Baltic Sea is a clear reference；findings refers back to the scientists’ observations；in this area identifies a place more specifically．

从这里的解释可以看出findings 的确是指代的一个句子，是对前面句子的总结，相当于observations,而observations 并没有直接出现在句子中.

虽然第一提已经想通了，但是第二题始终觉得A没有错误，请哪位大虾进来指导一下第二题吧，急！

我不知道WHAT能不能够引导宾语从句？－－貌似不能

比如： sb find that。。。。

sb find what。。。。？除非是sb find 【what sb always looking for is。。。】

就是用主语从句做原句中得宾语成分这样是可以得

所以第二题得 what they had not previously considered a possibility --better control 要加is才通

这个是ｗｈａｔ作为关系代词的宾语从句，不是主语从句，从这个角度看A没有错

(1)a vantage point位置不对，成了整个因果句的同位语；而原文是作为she knew many of the leaders of colonial Amercia and the American Revolution personally的同位语。
