参考ron的claim和facts

1.removal is better.

2.

you can't use 'resulting from' as an adverbial modifier（不修饰动词，只修饰名词）, as is done here. in general, 'resulting from' is only used as an adjective modifier, almost always without a comma, as in
the pollution resulting from the chemical spill forced all the local residents to evacuate.

all you need to know, there, is that __ing modifiers have to adopt the timeframe of ... something in the sentence.
NOTHING in that sentence is happening in the same timeframe as "placing women...".
that placement is something that won't occur until well after everything else in the sentence -- many many years after these women are students.
since the __ing modifier doesn't share a timeframe with ANYTHING in the sentence ... it's wrong!

相差五年，四年是common year（365），一年是leap year（366），所以相差天数365*5+1=1826，除以7余6，周五过6到周四

join in: to take part in an activity with other people,this wording implies that the rich nations are colluding with each other, metaphorically holding hands, deciding together to become more lax about pollution. (choice a expresses the correct meaning, which is that the slide is happening and that rich nations are individually joining it.)

曼哈顿好像明确说了that在gmat中不能修饰人吗= =
我觉得attempt和goal还是有区别的==

A选项：比较对象不同；
B选项：比较对象应该是the eyes of the ...adapt to... VS the eyes of ...do...-----此选项中does表示不了眼睛复数所做的事；them指眼睛，但是应该指代the elephant seal,所以应该是单数，与后面的its feeding...呼应；
D选项：同A错误
E选项：it指代有问题

老师，E选项从外延和内涵的角度不能理解，你上课时举了一个宾补的例子是I see him standing on the ground. 当时我问你看怎么给他添加属性，你说你看过去，在你的视角里他才站在那里，find这个词和see应该是一样的吧，为什么就不能加宾补了呀？with引导的独立主格能表示一种转折关系么，如果不行，那我只能通过这一点选D了，请老师解答

曼哈顿上说了伴随状语ing形式是可以修饰前面整个句子的吧，表达整句事件的结果
感觉是逗号用在greatly reducing前面，很像破折号的解释完了，后面reducing也有可能像修饰前面整个大句子， anthropologists believe..的结果
如果就是修饰前面ancestor这句话，也应该是像B那样说明是个什么event，来解释population bottleneck

A选项：it指代有误；fossils为复数；
B选项：has been--have been
C选项：that was－－awkward and wordy; was无法作为复数名词的系动词；
E选项：was主谓一致；

A选项：比较对象不对等：prices now VS time; 'raised...prices' 和 'floods and drought... are hurting crops'两个动作要平行；
C选项：比较对象不对等
D选项：比较接＋than；
E选项：hight than;

A选项： most rapidly vs and slower不平行；
B选项：which指代不明确；
D选项：travel和ricochet做为合句不正确，应让travel做伴随状语。这是因为，合句是并列关系，状语是从属关系，本题中，“地震波在冷的条件下更快”是“地震波在内层跳动”的一个属性，即，跳动这个行为的速度属性。因此，两件事只能是从属关系，而不能是并列关系。另外，slower错误同(A)。
E选项：and that--wordy;

rubber tapping：橡胶加工

A选项：appear as equipped应改为appear to have been equipped。实际上，appear as和appear to do的意思是不同的。appear as的意思是：以...出现；for facing any obstacle应改为不定式短语to face any obstacle；
B选项：appear to have been equipped表示过去；
C选项：as equipped不表示似乎，看起来像；时态过去时；path单数
D选项：同C；
E选项：for facing改成to face

选项B根本没有提到“缺乏完整信息”，显然错误。

A选项：'via computer' rather than' on paper'
B选项：where is not idiomatic--in which;电脑主动发出这个动作－？
C选项：同B
D选项：where is not idiomatic--in which;
E选项：in place of on paper--wordy

个人觉得...brightening和knocking既不是单纯的cloud也不单纯是storm,而是cloud trigger storm所造成的结果，所以用现在分词结构表示这个过程的结果....而cloud和storm这两个其中任何一个都不能单独造成后面的结果。

A选项：'that were cut...' and 'that were arising...' are unnecessarily wordy and creating confusing sentence structure.
B选项：yields不符合主谓一致（the first trenches）;
C选项：'having been cut...' is wordy; 'arising simultaneously' 要后跟with才可以；
D选项：yields不符合主谓一致；also 无意义；

B选项：growing as big as 30 feet long,由于The 32 species和whale均可以发出grow这个动作,是有歧义的；
C选项：growing,由于The 32 species和whale均可以发出grow这个动作,是有歧义的；grow up to 是“长大后会怎么样”的意思,应换成grow to be...
D选项：主谓不一致－－includes-include; as big as不能修饰长度；
E选项：错误同D；it多余，去掉；

核心词的问题，核心词是基因是简单和精致的这个point，而非基因本身这个idea。
