标题: 跪求大神帮忙解释一道题
Most of the country’s biggest daily newspaper had lower circulation in the six months from October 1995 through March 1996 than a similar period a year earlier.A. a similar period
B. a similar period's
C. in a similar period
D. that in a similar period
E. that of a similar period

OG 2018 第784题，官方解释只说 in the six months 要和介词短语 in a similar period 平行，我选了 d
求解释为什么不能加 that 指代 circulation?? 难道不是报纸的circulation在不同时间的比较？

作者: gongxiaorong 时间: 2017-10-27 08:13
D选项应该改成those had吧，比较的对象是most of the country's biggest newspaper在不同period的circulation吧。

作者: gongxiaorong 时间: 2017-10-28 03:43
两种比法： 1）the circulation in X is lower than THAT in Y ;2) have a lower circulation in X than IN Y...
看这里前面的未划线部分有had，所以选第二种

补充一下关于DE为什么错~

楼主先看一下这道题

According to recent studiescomparing the nutritional value of meat from wild animals and meat fromdomesticated animals, wild animals have less total fat than do livestock fedon grain and more of a kind of fat they think is good for cardiac health.

A. wild animals have less total fat than do livestock fed on grain and more of a kind offat they think is

比较正确

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

比较正确

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

比较错误

D. total fat of wild animals is less than livestock fed on grain and they havemore fat of a kind thought to be
比较错误

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

比较错误

C选项和这道题的DE选项是不是很像！

实际上这里是主语比较，比较的是wild animals和livestock，所以C是错的。

同理主楼的DE，比较的是两个时期的newspaper。

E选项就有点像本题的正确选项，应该要改成Total fat is less in wild animals than in livestock.

再看这道题

Prices at the producer level are only 1.3percent higher now than a year ago andare going down, even though floods in the Midwest and drought in the South arehurting crops and therefore raised corn and soybean prices.

(A) than a year ago and are goingdown, even though floods in the Midwest and drought in the South are hurtingcrops and therefore raised

(B) than those of a year ago andare going down, even though floods in the Midwest and drought in the South arehurting crops and therefore raising

(C) than a year ago and are going down, despite floods in theMidwest and drought in the South, and are hurting crops and therefore raising

(D) as those of a year ago and are going down, even though floodsin the Midwest and drought in the South hurt crops and therefore raise

(E) as there were a year ago and are going down, despite floods inthe Midwest and drought in the South, and are hurting crops and thereforeraising

这里AB的比较都是对的，A比的是时间状语，B比的是prices。
所以上一道题的D选项：total fat of wild animals is less than livestock可以改成：Total fat of wild animals is less than that of livestock.
——————————总结一下正确的比较合集：

1. My idol has more money than me.

不能是My idol has more money than THAT of me.

因为比较对象是我和我爱豆

同理：Newspaper has less circulation in X THAN in Y.不能用Newspaper has less circulation in X THAN THAT in Y.

2.Money of my idol is more than that of me.比较的是money

3.楼上说的两个正确比较方法~Circulation is less IN X THAN IN Y.
Newspaper has less circulation in X THAN in Y.

在D、E选项中，OG解释that指代unclear，但是很明显可以知道是指代circulation，什么时候that才能算是指代明确呢？

一个帖子找到我三道错题，真快哭了。

补充说明:比较-主语比较
1、对主谓宾全的句型主语比较:A do sth than B do.(AB为对等名词，加do是为了显示这是一个可
以发出动作的名词，因而确定是主语，进而确定是主语对比)。时态要据后定。Therebe 句型等同于一般的主谓宾俱全的句型。
主语若相同，可省，但助动词不能省。如:
As a result of the continuing decline in the birth rate, [fewer people] will enter the labor force [in the
1980’s] than (few people省略)did [in the 1960’s and 1970’s], a twenty-year period during which
people born after the war swelled the ranks of workers. 2、对只有主谓(如果主语有定语成分，必须要that/those来指代)，没有宾语的句子，因为没有宾语，只可能有主语比较，因而不需要重复do来确认这是一个可发出动作的主语，所以其比较形式如下:
I eat faster than you.注意与下句区别 I eat apple faster than you do 如果写成 I eat apple faster
than you 按GMAC的理解，从语法上就变成我吃苹果比吃你快，成了宾语比较。逻辑上显然不通。 3、主系表结构的比较与主谓结构相同。如果时态不一致，则需补出助词，如:
The economy of Florida is more diversified than it was ten years ago

这个prep中的解析，我觉得讲的也很好，就证明了为什么
the circulation is lower in a than that in b ,这里 that后面不需要助动词！

我觉得大家都搞复杂了，Dustin对于比较的看法是，如果你觉得C比D有省略，那么先看你觉得是省略了的那一个，如果有歧义就删掉，如果没有选他就好。
这个思路和Ron讲比较的思路一模一样，不需要去区分比较的类型，只需要看比较词（比如than）后面的词，在比较词的前面有没有可以对应的，有就是OK的比较，没有，那么这个比较就是不合逻辑的。
举例：gas prices were higher in 2007 than in 1997.你看蓝色的句子前后是不是都有？这个比较就是没有问题的。
gas prices were higher in 2007 than those in 1997. 看到没，前面缺少一个可以指代的名词，那么这个比较就是有问题的。
因此，从语法和句意逻辑这两个需要优先解决的层级上来说，CD都是没有问题的，为什么选C，很简单，因为GMAT并不是要语法正确的选项，同样要求在语法正确，句意合理的前提下，表达要清晰、简洁！！
同样的意思，C可以用比D少一个词来表达，那么久选C。

第二个例子里的those不是可以指代gas prices 吗？为啥说缺少一个可以指代的名词呀

作者: 地板流的熊猫 时间: 2019-12-15 11:33

因为你要比的是不同年份的gas price，那么你看比较词的后面是those in 1997，那么前面一定要有一个something in 2007, 而前面是没有的，只有一个gas price，第二个例子的正确改发是，gas prices in 2007 were higher than those in 1997 ,但是这个比起来没有gas prices were higher in 2007 than in 1997简洁。你可以去Manhattan搜一下Ron专门讲比较的帖子。这个例子就是Ron给的。

在前面同学们的基础上，提个简化的思路大家看对不对，that/ those在比较里的指代只能是前述主语，不能指代前述宾语，这个也echo了代词部分优先指代主语的原则。
不知道大家有没有见到反例，求轻拍。

that 这里只能指代 lower circulation 哦，这样代入句子就不对了。

作者: 拉美 时间: 2020-9-5 19:27
1.关于比较结构省略，省略的是相同的主谓语 2.关于meaning的理解前半句的意思，in the six month（是整个句子的时间状语）把c补全就是Most of the country’s biggest daily newspaper had lower circulation in the six months from October 1995 through March 1996 than （most of the country’s biggest daily newspaper did）in a similar period a year earlier 而反观d选项，in a similar period 是向前修饰that（circulation）相当于是定语而不是后句的时间状语

请问为什么A不行呢？a similar period感觉前面能找到对应的部分呀？

作者: 大大的刀刀 时间: 2021-8-6 22:25

A没有比较对象了吧，前面是circulation in the six months,是一段时间内的情况，后面也应该是在另外一段时间的情况，不能直接和月份比较啊，至少应该是in a similar period 根据前面一个同学说的常见结构， 1）the circulation in X is lower than THAT in Y ;2) have a lower circulation in X than IN Y…这题C是最优的
