我本来也选了A 后来仔细看 A的最大错误在于cross

cross逻辑上应修饰scientist 但是 他可修饰insects 好像也可修饰moth造成歧义

A. Imported into Massachusetts from Europe in 1869, the gypsy moth was used by a French scientist in an attempt at developing a strong strain of silk-producing insects, crossing gypsy moths with adult silkworms.

一点拙见

同意楼上。

neverback

大家有没有发现一个问题

C,D,E里是说MOTH被SCIENTIST IMPORT的

可是句意是说MOTH被SCIENTIST USE

不是改变句意吗?

我选A

同意楼上的说法. 查了一下字典, attempt做名词时也可以和at连用表示试图．如下：

attempt
n
（常与at, on, to连用）努力；尝试
She made an attempt to cook the dinner.
她试着做这顿饭。

make an attempt at
打算; 试图

首先，问题不是在attempt上，而是整个句意的理解．法国科学家应该是使用ＭＯＴＨ做实验而不是他亲自去进口ＭＯＴＨ．Ｅ选项与Ａ在句意上完全不同．

其次，Ａ选项中的ＣＲＯＳＳ并没有造成修饰的误解（反驳第１１楼的说法），ＣＲＯＳＳＩＮＧ是进一步解释前一句所描述的实验过程，这个科学家的实验＂developing a strong strain of silk-producing insects"　是ＣＲＯＳＳＩＮＧ．．．．

我总觉得D 中

The gypsy moth was imported into Massachusetts from Europe in 1869 by a

French scientist attempting to develop a strong strain of silk-producing insects by

crossing gypsy moths with adult silkworms.

要是改成: by a French scientist's attempting to 就没问题了. By sb doing 感觉好象很不爽. 一般动名词前面不是所有格形式吗?

但是倾向D的同胞们所说的也蛮有道理但还是不能解除我对A的...

这里defense 一下A:

1. french scientist 怎么会干起进口生意呢? 应该是别人进口来了,他用才对吧. A 表达的比D有道理.

2. 另外楼上所说的crossing 进一步解释developing 也有道理哦.

还请继续讨论非到定论不可. NN再请进来.

嗯  看到有人反駁我十一樓的說法  不得不再來講一下

我覺得A的crossing引起岐意 是GMAT的大忌  D中的by 已經把used的意思表達出來了

至於crossing的岐意可參考OG127

127. In theory, international civil servants at the
United Nations are prohibited from continuing to draw salaries from their own
governments; in practice, however, some governments merely substitute living
allowances for their employees’ paychecks, assigned by them to the
United Nations.

(A)
for their employees’ paychecks, assigned by them

(B)
for the paychecks of their employees who have been assigned

(C)
for the paychecks of their employees, having been assigned

(D)
in place of their employees’ paychecks, for those of them assigned（B）

(E)
in place of the paychecks of their employees to have been assigned by them

In choice A, the
phrase assigned by them modifies the
adjacent noun, paychecks: the
sentence implies that paychecks, rather than employees, work at the United
Nations. In C, the phrase having been
assigned... is uncertain in reference, making the sentence unclear. By
using in place of instead of for, choices D and E create the
unidiomatic and redundant construction substitutes
x in place of y. Moreover, D, aside from being wordy, is unclear because
the pronoun them has no unambiguous
antecedent; and in E, their employees to
have been assigned by them is wordy and awkward. Choice B, the best answer,
properly uses the phrase who have been
assigned... to the United Nations to modify employees.

XDF的老师说，A的错误在于，介词，介词，句子这种结构不好，要改成介词，句子，介词。

以下是引用leeon在2004-9-20 9:54:00的发言：

102中的错误在it，with sth done这样的结构是idom的。后面加了it就错误。

这里的by sb doing sth也是一种很长见的结构。分词结构充当介宾结构中的宾语补足语。在OG中有一种很完美变体就是sb do sth by doing sth。

by a French scientist attempting to develop a strong strain of silk-producing insects by crossing gypsy moths with adult silkworms.

可不可以理解为attempting to ....分词作定语修饰a French sicientist呢？我个人觉得在GMAT中，介词by后面加复杂成分是awkward。

这是针对哪个选项说的呢

Avantasia

C. To cross gypsy moths with adult silkworms, in attempting the development of a

strong strain of silk-producing insects, a French scientist in 1869 imported the

gypsy moth into Massachusetts from Europe.

D. The gypsy moth was imported into Massachusetts from Europe in 1869 by a

French scientist attempting to develop a strong strain of silk-producing insects by

crossing gypsy moths with adult silkworms.

这里C确实没有D好, 但是不知道除了倾向于使用动词外, C还有什么地方不对吗?

请教了.
