北美二战娘子军

英台的这题很好，我刚刚也抄下来了，这题最重要的是两个并列的从句，一定要用同样的引导词。。。where 对　where

祝英台

是的，有题目中提到可以跳跃修饰前面的bridge，但是我查了一下所有的题目，如果单考这个名词的修饰，肯定是修饰末尾词。举个prep的例子。

The list of animals that
   exhibits a preference of either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include the lower vertebrates.

(A) exhibits a preference of either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include

(B) exhibits the preference to use either the right or the left hand (i.e., claw, paw, or foot) has been expanded and includes

(C) exhibit a preference in either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include

(D) exhibit a preference for using either the right or the left hand (i.e., claw, paw, or foot) has been expanded to include

(E) exhibit the preference as to either using the right or the left hand (i.e., claw, paw, or foot) has been expanded and includes

这里的animals后面的that是限定，所以不是修饰list而是修饰animal。所以考到限定的主谓一致一定是修饰紧跟名词。

再看这道，一样的考点！一定要记住啊。

With a new park, stadium, and entertainment complex along the Delaware River, Trenton, New Jersey, is but one of a large number of communities that is looking to use its waterfront as a way for it to improve the quality of urban life and attract new businesses.

(A) is looking to use its waterfront as a way for it to improve the quality of urban life and attract

(B) is looking at using its waterfront to improve the quality of urban life and attract

(C) are looking to use their waterfronts to improve the quality of urban life and attract

(D) are looking to use its waterfront as a way of improving the quality of urban life and attracting

(E) are looking at using their waterfronts as a way of improving the quality of urban life and attract

所以我很负责地跟各位ＭＭ说，that引导的限定一定是限制紧跟名词的。

英台的那题里，that是指land，就是大陆桥的大陆曾经出现过。

关于分词修饰，英台说的主动和被动是一个方面，另一个方面，过去分词表示一种结束的状态，而现在分词表示的是一直持续的状态，一直存的感觉。在修饰名词的时候，一般ＥＴＳ有两种方法，一种分词做后置修饰，一种是用定语从句，他很喜欢混在一起考，区别就是现在分词表示持续状态，而定语从句表示解释，通常是一次性的动作。

看这题

In 1997, despite an economy that marked its sixth full year of uninterrupted expansion with the lowest jobless rate in a quarter century, the number of United States citizens declaring themselves bankrupt has jumped by almost 20 percent, at 1.34 million.

(A) declaring themselves bankrupt has jumped by almost 20 percent, at
                    

(B) declaring themselves bankrupt jumped by almost 20 percent, to

(C) who declared themselves bankrupt has jumped by almost 20 percent, to

(D) who declared themselves bankrupt jumped almost by 20 percent, at
                

(E) to declare themselves bankrupt jumped almost by 20 percent, at

为什么这里用现在分词而不用定语从句，因为表示了一种持续的感觉...可以细细体会一下之间的区别。

还有这道

In the mid-1920s the Hawthorne Works of the Western Electric Company was the scene of an intensive series of experiments that would investigate changes in working conditions as to their effects on workers' performance.

(A) that would investigate changes in working conditions as to their effects on workers' performance

(B) investigating the effects that changes in working conditions would have on workers' performance

(C) for investigating what the effects on workers' performance are that changes in working conditions would cause

(D) that investigated changes in working conditions' effects on workers' performance

(E)
  to investigate what the effects changes in working conditions would have on workers' performance

感谢Lena MM,彻底明白了！ ，说了这么多，解解渴吧~

英台，我好像刚才误解你的意思。。。我知道你的困惑了。。。

第一。关于that的指代，是可以跳过紧跟的修饰词直接指代中心词。

It was only after Katharine Graham became publisher of The Washington Post in 1963 that it moved into the first rank of American newspapers, and it was under her command that the paper won high praise for its unrelenting reporting of the Watergate scandal.

 

(A) It was only after Katharine Graham became publisher of The Washington Post in 1963 that it moved into the first rank of American newspapers, and it was under her command that the paper won high praise

(B) It was only after Katharine Graham's becoming publisher of The Washington Post in 1963 that it moved into the first rank of American newspapers, and under her command it had won high praise

(C) Katharine Graham became publisher of The Washington Post in 1963, and only after that did it move into the first rank of American newspapers, having won high praise under her command

(D) Moving into the first rank of American newspapers only after Katharine Graham became its publisher in 1963, The Washington Post, winning high praise under her command

(E) Moving into the first rank of American newspapers only after Katharine Graham's becoming its publisher in 1963, The Washington Post won high praise under her command

比如这句，正确答案里面的that跟在了1963后面，其实是指代了post。但是基本上所有的跳跃题都没有在考点出现。你明白我的意思？就是说that如果跳跃了，肯定不是考点和破题点。

２.ＥＳＴ考到定语从句中的限定和非定，好像只考两种情况，一种是主谓一致，考你知道不知道that或者which指代的是什么。这类题就像前面prep举的例子中说明的，全都是指代紧跟名词。第二类考的是限定和非定的区别。限定是局部概念，非限是全部概念。可以把分词理解成非限。（这个考点比较难，完全就要靠自己个人的理解和逻辑关系了，所以不到最后关头，不要以此来判断句子的正误）

以上就是我对所有这类题的理解。。。姐妹们指证。。。

LENA，你上来啦，哈哈

语法谢谢英台的问题和LENA的解释，再细看看。。。

数学是12，怎么做的呀？

以下是引用zy39063在2008-4-11 23:26:00的发言：

一道PREP数学求教：

一个调查某镇每个人平均每周看电视的小时数，调查结果是a mean of 21 hours and a standard deviation of 6 hours，PETER上周看电视数between 1 and 2 deviations below the mean，问PETER上周看电视小时数可能是哪一个

30,20,18,12,6

我总是对这类题搞不清，应该是对标准差的理解问题吧

mean代表中间的那个数，standard deviation表示每个区间之间的距离。

低于一个deviation表示２１-6=15, 2个就是21-6*2=9

两个区间之间就是９－１５之间,所以就是１２

zy39063

哦，明白了。我主要是没理解between 1 and 2 deviations below the mean的英文意思

俺发现俺数学理解题意常常有问题

狠狠熊抱

又上两题

1. For every positive even integer n, the function h(n)is defined to be the product of all the even integers from 2 to n, inclusive. If p is the smallest prime factor of h(100)+1,then p is

between 2 and 10, 10 and 20, 20 and 30, 30 and 40, greater than 40

我选的E，是对的。我的思路是h(100)是50个偶数相乘，结果应该是偶数，加1以后就成了奇数，最大的质数就是它本身，所以肯定是大于40的。这个思路好象有点问题，如果是对的，为什么给的答案都跟10的倍数有关，而且是大于40呢？

1.Are at least 10% of the person in X who are 65 years old or older employed?

(1) in x, 11.3% of the population is 65 years old or older

(2) in x, of the population 65 years old or older, 20% of the men and 10% of the women are employed

怎么理解这个问题：如果理解成X中至少有10%的人是65或以上并且有工作,我觉得应该考虑两个条件；如果理解成X中65或以上的人至少有10%的有工作，那应该是B。答案是B 可是我觉得问题应该理解成第一种呀，错在哪呢？

MM的第一题好难，我想不出来，所以问老公了。。。

１.　首先，ＭＭ没看清，他问的是Ｐ是最小的质因数的范围。

先把式子化简一下：h(100)+1=２*４*６*８...*100+１＝２（１*２*３...*50)+1 ---把２提出来了。

其实后面那式子就表示式子被１－５０所有的数除都余１。说明本来这个数可以被１－５０所有的数整除，加了１之后，被所有的数都余１,也就是说明１－５０内没有数是它的质因数，所以最小的质因数一定是大于５０的。

2.　题目问的是是否１０%的员工是超过６５岁的？

条件二：在所有的６５岁以上的员工中，男占２０%，女占１０%，说明一共３０%。回答问题，否。

多谢LENA和你的NN老公

第一题很清楚了，第二题我写时省略了是否，还有点没绕过来，再想想
