OG22-847

847.Unlike the nests of leaf cutters and most other ants, situated underground or in pieces of wood, raider ants make a portable nest by entwining their long legs to form “curtains” of ants that hang from logs or boulders, providing protection for the queen and the colony larvae and pupae.

A. the nests of leaf cutters and most other ants,
B. the nests of leaf cutters and most other ants, which are

C. leaf cutters and most other ants, whose nests are
D. leaf cutters and most other ants in having nests
E. those of leaf cutters and most other ants with nests

不是很懂D选项的解释：This sentence correctly compares leaf cutters and other ants with raider ants, but the prepositional phrase in having nests suggests that it is raider ants, not leaf cutters and most other ants, that have nests situated underground or in pieces of wood; however, the rest of the sentence indicates that in fact raider ants’ nests are not situated in such locations.

为啥in having nests就能把nests situated underground or in pieces of wood修饰的对象从leaf cutters and most other ants,转变为raider ants？这个选项一看就是错的，可是我搞不明白它的解析的意思。。就很抓狂。SOS

楼主提供的解释是说，问题出在in having nests，这让人误以为：是raider ants,（而不是leaf cutters and most other ants，）筑巢地下或wood
但接下来的句子指出来事实上raider ant不在这些地儿筑巢

关于此题，GmatLa的大神给出了完整解析如下：

题目分析：
原句中具有明显的“比较”提示词unlike，在绝大部分的情况下，见到这个词证明本题会考查“比较”。

选项分析：

A选项：比较对象不对等，应该是两种生物的比较（leaf cutters and most other ants和raider ants），而不能是巢穴（nests）和动物的比较。

B选项：比较对象错误同(A)。

C选项：Correct. 本选项在语法和逻辑上均是正确的。

D选项：本选项具有较强的迷惑性。in having nests situated underground or in pieces of wood是由in引导的介词短语。这表示，having nests situated underground or in pieces of wood必然是一个动名词短语（介词身后只能加名词），因此，这个having不具有“逻辑主语”是谁的问题，因为“名词”从来没有逻辑主语（要想给动名词或者名词添加自己的主语，必须用所有格的形式，例如most other ants' having nests）。因此，在本选项中，having nests并没有主语，即，我们不知道是谁在拥有这些巢穴。但在逻辑上，显然是蚂蚁们拥有这些巢穴，因此，应该用定语从句。

E选项：比较对象错误同(A)。

也就是说in+doing的形式都无法明确指出逻辑主语，可以这么理解吗大佬
