10. Used by many natural history museumcurators in the preparation of animal skeletons for display, dermestid beetles feed on the decaying flesh of animal carcasses, pulling with its mouthparts to strip the bone of any residual fat or muscle tissue.
        A. dermestid beetles feed on the decaying flesh of animal carcasses, pulling
        B. dermestid beetles feed on the decaying flesh of animal carcasses and pull
        C. the dermestid beetle feeds on the decaying flesh of animal carcasses in order to pull
        D. the dermestid beetle feeds on the decaying flesh of animal carcasses, pulling
        E.  the dermestid beetle feeds on thedecaying flesh of animal carcasses and it pulls

选项解析：
The plural subject in the original sentence,dermestid beetles, does not agree in number with the singular pronounits, which appears in the non-underlined part of the sentence. In order to correctly agree withits, the subject must be singular:the dermestid beetle.
(A) This choice is incorrect as it repeats the original sentence.
(B) The plural subject dermestid beetles does not agree in number with the singular pronoun its, which appears in the non-underlined part of thesentence. In order to correctly agree with its, the subject must be singular: thedermestid beetle. While verb tenseconsistency is usually desirable, using two present tense verbs in thissentence effectively separates feed and pull into twoindependent actions: the beetles feed on the decaying fleshand, separately, pull with…mouthparts. The original meaning of the sentence is that the pulling occurs aspart of the main verb feed,not independent of it.
(C) While the singular subject the dermestid beetle correctly agrees in number with the singular pronoun its, the modifier in order to pull altersthe original meaning of the sentence. The beetle feeds by using its mouthparts.The beetle does not feed in order to use its mouthparts.
(D) CORRECT.The singular subjectthe dermestid beetlecorrectly agrees in number with thesingular pronoun its. Also, the formpullingcorrectly indicates thatpulling with itsmouthpartsoccurs as part of the main action feeds, not independent of it.
(E) The singular subject the dermestid beetle correctly agrees in number with the singular pronoun its. While verb tense consistency is usually desirable,using two present tense verbs in this sentence effectively separates feeds and pulls into two independent actions: the beetle feeds on the decaying flesh and,separately, pulls with…mouthparts. The original meaning of the sentence is that the pulling occurs aspart of the main verb feeds,not independent of it. Finally, the use of the pronoun it is unnecessarilywordy; the subject of the verb pulls, the dermestid beetle, is clear without theuse of it.

题目点评：
本题涉及考点：代词，句子结构

观察五个选项可以发现，主谓一致不存在错误，区别只在于单复数主语的选择。出现这样的选项一般存在两种考察的可能：第一，代词。根据未划线的部分出现的代词来判断主语单复数，通常代词出现在后半句未划线部分。第二，逻辑意思。根据句意来判定主语的单复数形式。

通过未划线部分“its”判断，迅速排除A,B选项。剩下C,D,E，区别在于后半句与主句的关系不同。出现这样的情况，根据句意判断是最合理的。Pulling with its mouth parts tostrip the bone of any residual fat or muscle tissue 是伴随状语，表伴随的条件，具体的说就是说明feed 这个动作是如何进行的。

另外，从定冠词the 符合逻辑意思的角度来排除A,B选项也是合理的。

思维点评：
1. “D的pulling既不是表结果又不是并同时发生”——innerwarrior
V-ing 从句的三个作用：表伴随（的结果、状态、条件、原因等）；修饰主语；就近修饰前面一个名词。

做题小tips：
语法错误分两种，一种是绝对性错误，一种是有效性错误。我还是建议大家先从绝对性错误入手，再考虑有效性错误。因为有效性错误并不代表这个选项一定是错误的，GMAT 要求大家在五个选项里选最优的，而不是绝对正确的。

哇~10出来的好早啊~毛毛辛苦了^^

选D。
被用来准备动物骨骼的展览，某甲壳虫[想到了Beatles^^] 以动物尸体腐烂的肉为生，用它的嘴剔骨吃肉。
未划线部分its mouth, 所以主语是单数 the dermestid beetle AB排除
CDE的差别在feed on decaying fresh..和pullwith mouth balabala..的关系。
根据逻辑意思很明显得出feed是总体动作，pull是detailed action
C 后者是前者的目的，逻辑错误
E 后者和前者并列，逻辑错误
D 做伴随修饰前面整体动作，逻辑主语是the beetle. Bingo~

所以选D

（被 博物馆馆长 用来准备 动物骨骼展览的）皮囊虫要吃动物尸骨的腐败的肉，用它的口器把骨头上残留的脂肪和肌肉组织弄完。

考点： 冠词，伴随

A 专指被 博物馆馆长 用来准备 动物骨骼展览的那一种皮囊虫，特指应该加the
B加the，错误同A； pull并不是和feed 并列，用分词ing做伴随状语，表方式更好。
C 并不是 为了 用它的嘴 吃完肉， in order to 没有 伴随表方式好。
D 正确
E pull并不是和feed 并列，用分词ing做伴随状语，表方式更好; 而且就算是并列，it也破坏了平行

PS： 关于定冠词the的使用，OG上有道讲吸血虫的和这道题如出一辙，大家可以参考。

请问知道是OG上的哪一题嘛?^^
这题我是根据划线部分后面的its来判断，AB错误的。
然后就看pull的形式判断，选D。
C中in order to 表目的，改变句意
E中改为并列了，也是改变句意

sandychen168

果断选D！！
its mouthparts可以看出用单数

       A       dermestid beetles feed on the decayingflesh of animal carcasses, pulling  [缺少the, 有指所有dermestid beetles的歧义; feed和its不搭,错]
       B       dermestid beetles feed on the decayingflesh of animal carcasses and pull [缺the; feed和its不搭; feed和pull变成平行，导致illogical]
       C       the dermestid beetle feeds on thedecaying flesh of animal carcasses in order to pull  [in order to...表目的，此处不符逻辑]
       D      the dermestid beetle feeds on the decayingflesh of animal carcasses, pulling
       E       the dermestid beetle feeds on thedecaying flesh of animal carcasses and it pulls [用OG的原则哈, it 比较wordy; pulls 和feeds平行，不符逻辑]

看来句意真的灰常重要 ╮(╯▽╰)╭

clover033

选D。


首先可以先参考未划线部分，with its mouth，its是单数形式的所有格形式，故指代的句子的主语应该也是单数形式。句子主语为 beetle，显然用复数形式beetles不对，排除A,B。
其次，动词的-ing分词形式表示伴随。主语the dermestid beetle是pull这个动作的发出者，pulling with这个动作是伴随着主语的feed这个动作进行的；而pull这个动作并不是目的，故排除C；pull也不是和feed这个动作并列，排除E。

       A       dermestid beetles feed on the decayingflesh of animal carcasses, pulling
       B       dermestid beetles feed on the decayingflesh of animal carcasses and pull
       C       the dermestid beetle feeds on thedecaying flesh of animal carcasses in order to pull
       D      the dermestid beetle feeds on the decayingflesh of animal carcasses, pulling
       E       the dermestid beetle feeds on thedecaying flesh of animal carcasses and it pulls

好多字凑在一起，以为一堆生词。。。汗
后面划线外是its，所以前面主语一定是单数，排除AB
D的pulling既不是表结果又不是并同时发生，排除
C的in order to意思不对，吃东西为了pull with it mouth？
所以E

貌似错了。。。逗号+Ving不是说表结果的话，应该是对整句的修饰嘛，但我记得og有一题，是说如果2个动词主语都一致的话，不可能是表结果的。。。
往指点～

找到OG26
26.       Emily Dickinson's letters toSusan Huntington
Dickinson were written over a period beginning a few
years before Susan's marriage to Emily's brother and
ending shortly before Emily's death in 1886.
outnumbering her letters to anyone else.

如果outnumber的主语明显是letters嘛，所以和were written是同一个主语。如果按主语一致不可能是结果状语的话，我能理解把它排除掉。其实从逻辑意思看，A也没什么不多，就因为他的信写了那么久，才结果造成数量超过别的任何人～

       D      the dermestid beetle feeds on the decayingflesh of animal carcasses, pulling
       E       the dermestid beetle feeds on thedecaying flesh of animal carcasses and it pulls
根据没划线部分的its 排除AB  根据句意，是the dermestid beetle feeds on the decayingflesh of animal carcasses导致了后半句的结果，应该用逗号+Ing表因果伴随，选E
C中的in order to 不能做后置定语修饰
E中and 后面的It重复了主语  应该省略
