01.14号作业:
OG11(黄皮) CR-117
Caterpillars of all species produce an identical hormone called “juvenile hormone” that maintains feeding behavior. Only when a caterpillar has grown to the right size for pupation to take place does a special enzyme halt the production of juvenile hormone. This enzyme can be synthesized and will, on being ingested by immature caterpillars, kill them by stopping them from feeding.Which of the following, if true, most strongly supports the view that it would NOT be advisable to try to eradicate agricultural pests that go through a caterpillar stage by spraying croplands with the enzyme mentioned above?
(A) Most species of caterpillar are subject to some natural predation.
(B) Many agricultural pests do not go through a caterpillar stage.
(C) Many agriculturally beneficial insects go through a caterpillar stage.
(D) Since caterpillars of different species emerge at different times, several sprayings would be necessary.
(E) Although the enzyme has been synthesized in the laboratory, no large-scale production facilities exist as yet.

这题好几个单词不认识,虽然选项没有设置太大的难度,但是花的时间太多.顺便问一下,on being ingested by immature caterpillars,为什么要用介词on?

CR-119
Adult female rats who have never before encountered rat pups will start to show maternal behaviors after being confined with a pup for about seven days. This period can be considerably shortened by disabling the female’s sense of smell or by removing the scent-producing glands of the pup.
Which of the following hypotheses best explains the contrast described above?
(A) The sense of smell in adult female rats is more acute than that in rat pups.
(B) The amount of scent produced by rat pups increases when they are in the presence of a female rat that did not bear them.
(C) Female rats that have given birth are more affected by olfactory cues than are female rats that have never given birth.
(D) A female rat that has given birth shows maternal behavior toward rat pups that she did not bear more quickly than does a female rat that has never given birth.
(E) The development of a female rat’s maternal interest in a rat pup that she did not bear is inhibited by the odor of the pup.

想多了^_^,误以为B选项是说当幼鼠碰到不是生育它的成年鼠时,就会放出更强的气味,象黄鼠狼对付敌人那样.

OG11(黄皮)阅读
RC-41) B选项qualified acceptance 粗心地将它理解为“高质量(完全)地接受”了,而实际意思是“有限制,有保留地接受”。

(A)  With
(B)  As
(C)  Being
(D)  Despite having

错选了A,实际上用with,语法上并没有错误.只是没有突出对比性,Gmat考查的是最佳答案,E选项更优.

OG11(紫皮)SC-30

(D)  had been as disturbing in his own time as it was
(E)  have been as disturbing in his own time as
根据单复数和时态可以得出正确选项B,但没有完全理解这句话的意思,disturbing是作动词进行时,还是作形容词,还是作为名词? 选项中的as...as的对称项是什么?

不知道有沒有人跟我一樣的問題?

作业情况:sc 33/50 66%  rc 5/5 100%

疑难题

49  Reporting that one of its many problems had been the recent extended sales slump in women's apparelthe seven-store retailer said it would start a three-month liquidation sale in all of its stores

(A)  its many problems had been the recent

(B)  its many problems has been the recently

(C)  its many problems is the recently

(D)  their many problems is the recent

(E)  their many problems had been the recent

我错选了b,答案说has been有延续的意思,所以不选,但我认为就是因为有延续的延续的意思,我才选择的B。一个公司出现的问题,才引出了公司新的销售政策来消除危机,也就是说,在政策开始以前问题都是未解决的,所以应该用has been

,不知我那里,理解错了,请大家指教!

01.16号作业:
错的这两题,还是没想明白
OG11(紫皮)SC-72
The gyrfalcon,an Arctic bird of prey, has survived a close brush with extinction;its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970’s.
(A)  extinction;its numbers are now five times greater than
(B)  extinction;its numbers are now five times more than
(C)  extinction,their numbers now fivefold what they were
(D)  extinction,now with fivefold the numbers they had
(E)  extinction,now with numbers five times greater than
错选了E,OG的解释是逗号使得后面整句话好像在修饰extinction,有一定道理,但明显extinction是不能with numbers的,如果硬要这么说,那么正确答案A中的its也可以说是指代extinction。感觉从语法角度来讲,A和E没有什么区别,形式和理解上A更好。

OG11(紫皮)SC-73
Analysts blamed May's sluggish retail sales on unexciting merchandise as well as the weather, colder and wetter than was usual in some regions, which slowed sales of barbecue grills and lawn furniture
(A)  colder and wetter than was usual in some regions,which slowed
(B)  which was colder and wetter than usual in some regions,slowing
(C)  since it was colder and wetter than usually in some regions,which slowed
(D)  being colder and wetter than usually in some regions,slowing
(E)  having been colder and wetter than was usual in some regions and slowed
用slowing这个分词结构,那么应该修饰的是前面整个句子,即"分析家责备May's迟钝的零售"这件事减缓了(slowing)"烧烤架和家具的销售";但个人觉得是"May's迟钝的零售"减缓了(slowing)"烧烤架和家具的销售"

1/17  homework

sc紫色81~113   4/32  82.5%

搞不懂的題目:

sc 99

Judge Bonham denied a motion to allow members of the jury to go home at the end of each day

instead of confine them to a hotel.

(A)to allow members of the jury to go home at the end of each day

instead of
  
confine them to

(B)that would have allowed members of the jury to go home at the end of each day insteadof confined to

(C)under which members of the jury are allowed to go home at the end of each day instead of confining them in

(D)that would allow members of the jury to go home at the end of the each day rather than confinement in

(E)to allow members of the jury to go home at the end of each day rather than be confined to

第一.這一題畫線部分應該延長至to confine them to

第二  我知道選項為E,也選對,但是對於C選項OG的解釋為members of the jury are the illogical object in confining them ,這句我不太懂它的意思,為什麼不合邏輯呢?

請大家幫我想想,謝謝
