新PREP1-188再讨论。有一个小小的疑问。

188.(26379-!-item-!-188;#058&001961)



Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.

A. Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are

B. Neuroscientists, having amassed a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are

C. Neuroscientists amassing a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are

D. Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood,

E. Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,

选A。对于D的问题是，过去的讨论帖中，大家都一致同意D由于改变句子重心被排除。

但是D的意思上，now drawing solid conclusions about how the human brain grows and how babies acquire language 可不可以是做have amassed的结果呢。。。

求指教。




感觉和这题情况很相似的是OG12-Q26，这题改变了原句强调的中心吧。

26. Emily Dickinson’s letters to Susan 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.

(A) 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

(B) Dickinson were written over a period that begins

a few years before Susan’s marriage to Emily’s

brother and ended shortly before Emily’s death

in 1886, outnumber

(C) Dickinson, written over a period beginning a few

years before Susan’s marriage to Emily’s brother

and that ends shortly before Emily’s death in

1886 and outnumbering

(D) Dickinson, which were written over a period

beginning a few years before Susan’s marriage

to Emily’s brother, ending shortly before Emily’s

death in 1886, and outnumbering
(E) Dickinson, which 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, outnumber

E不是改变句子重心了么。。。同问，A中的outnumbering为什么不能做前面整个句子的伴随结果。

求指教，多谢。

LZ要注意逻辑意思喔。第一题的have amassed是现在完成时表示已经发生过了。用now drawing来修饰表示伴随不合适。一个已经发生过的东西怎么能伴随着现在发生的问题呢。我是这样想的。。。
第二个有同样的问题。前面的分句是说某人给某人写信的时间范围，后面的分句是说某人给某人写的信很多。这两件事没有必然的联系，所以无法将它们互相修饰。E选项将前面的分句修饰主语，解决了这个问题。

多谢解答，但是我的疑问是，根据前人的帖子说：

在以下两个情况下要使用伴随状语

1、前一个分句的整体对后面某一个对象的作用

2、两个同时发生的动作

S+V+O，v+ing..形式中v-ing 2个功能

1：作为S+V+O的伴随结果，和S没有直接的逻辑关系，形容整句。

2：S是v+ing的逻辑主语，两个动作同时发生。

而我感觉疑惑的是，上面的两道题，可不可以以上两种情况的第一种，即前一个分句的整体对后面某一个对象的作用，作为S+V+O的伴随结果，和S没有直接的逻辑关系，形容整句。

这种用法例如 OG10-Q259 Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.

既然是作为结果，那么是have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood，这个状态，导致了now drawing solid conclusions about how the human brain grows and how babies acquire language的结果，所以这两个动作有时间先后。

疑惑是：前一个分句的整体对后面某一个对象的作用，即，后面伴随表示前面整句动作结果的句子，是否可以存在这种时间上的先后？

请斧正。

虽然我没太看懂LZ的问题。但是还是想重复一下吧。重新看一下句子的意思，前一分句说什么学家积累了大量知识。后一分句说solid conclusion。那么是先积累大量知识还是先总结出结论呢？我想还是应该把amassed在先吧。
不知道说的在不在点上。不在的话LZ表批我。。。

多谢童鞋解答。

童鞋说的极是，先是积累只是在前，然后才能draw conclusion。我纠结的地方就是觉得，因为积累在前，所以得出结论在后，那得出结论这个动作能不能做积累的结果状语？这与两个动作的先后关系并不矛盾，逻辑上，得出结论是知识积累的结果，只是想知道这种用法错在哪里了。
