关于with+n.+doing的错误有效性，请大家帮忙看看我的理解有错不？

Part of the proposed increase in state education spending is due to higher enrollment, since the number of students in public schools have grown steadily since the mid-1980's and, at nearly 47 million, are at a record high.

(A) enrollment, since the number of students in public schools have grown steadily since the mid-1980's and, at nearly 47 million, are at

(B) enrollment, with a number of students in public schools growing steadily since the mid-1980's and, at nearly 47 million, reaching是对的，只是没动词有效

(C) enrollment: since students in public schools have grown steadily in number since the mid-1980's and, at nearly 47 million, have reached

(D) enrollment: the number of students in public schools has grown steadily since the mid-1980's and, at nearly 47 million, has reached

(E) enrollment: students in public schools have grown steadily in number since the mid-1980's and, at nearly 47 million, are at

补充题：与B选项比较with的用法

52.  Although at one time children’s programming had been limited to a few hours a week, now, however, there are at least four cable networks that dedicate themselves entirely to shows produced specifically for children.

A.      Although at one time children’s programming had been limited to a few hours a week, now, however, there are at least four cable networks that dedicate themselves

B.      With children’s programming having been limited at one time to a few hours a week, now at least four cable networks have dedicated themselves

C.      Once limited to a few hours a week, there are now at least four cable networks with children’s programming that dedicate themselves

D.      Children’s programming was once limited to a few hours a week, but now there are at least four cable networks dedicated

E.      While children’s programming had once been limited to a few hours a week, at least four cable networks are now dedicated

A: at one time应该用once替换；had been过去完成时没有道理；dedicate应该用被动

B: with one’s doing应该替换成完整句；dedicate应该用被动

C: limited 没有可修饰对象; dedicate应该用被动

D: correct

E: had been过去完成时错，有once用过去时；

注意：

1、           at one time和once的配对出现

2、           one dedicate sth. to sth. ; sth. is dedicated to sth.

3、           with one’s doing是选从句做答案的标志

但是上面的题就是with+n.+分词短语做独立主格

the economy of Britain, France, and Germany, with the unemployment rate that has remained

with在句首要求逻辑主语, 在句尾时实际上应该修饰前面句子主语,但如果前面是名词, 很容易以为with是修饰前面跟着的哪个名词, 而不是前面句子的主语, .og里面有解释对这两种都有例题.

此题选项D:Germany,with..., 很容易产生歧义认为with修饰的是Germany, 所以不是正确答案.

我找了og的结论是，相同的意思，如果可以用从句（这个需要考察）或分词短语（这个好理解，with +n+分词短语=累赘），就不要用with.

最终结果: with one’s doing不对，应该接名词，with+N.+doing独立主格结构中的（可以放前面放后面，相当于状语，有逻辑主语问题）ing最好可以修饰前面的名词，如果是n做某事，主被动关系比较强烈这种就不对

其中绿色部分中间的部分是讨论帖子中大家的发言

想问问我的总结到底有没有错？另外这样的句型我也没找出来

顺便和MM讨论一下with的用法，不知你注意没有

with后可以＋ing，adj，介词短语还有+ n + that定语从句(比较少见的一种用法）

我觉得应该是介词的用法

1.      介词+简单名词对,----介词不要接从句, 不要接名词+句子, 不要接名词+doing  

Eg. 介词+从句错
                With stationary crests and troughs although they are formed by rapidly moving air  错（OG205）

Eg. 介词+句子错。based on how…..(OG90)

Eg. 介词+名词+doing错

With +N.+doing 错，with the composer himself staging it(错) (OG102)

at +N+doing错

for +N+doing 错（但要判断这个doing是现在分词而不是动名词
                ,像这个OG29的介词+动名词是对的
                for the building of ）

from ,besides ,except也是要接名词不能是句子或分词(OG68, OG95,OG102)

Eg.介词+名词
            对

With crests and troughs that remain stationary although the air that forms them is moving rapidly 对
            （OG205）

2.      介词短语的位置:没有逗号就是修饰前面那个名词，两边有逗号就小心是不是歧义,可能修饰两边（此时就是用定语从句更明确）

3.      介词短语做状语，最好放在句首，前边什么都没有，否则放那个词后边都可能和这个词形成歧义
                

所以我的理解就是如果是n做某事，主被动关系比较强烈这种就不对

(B) enrollment, with a number of students in public schools growing steadily since the mid-1980's and, at nearly 47 million, reaching 我认为这句话的with+n.+doing是对的,应该doing做后置定语修饰number，只是没动词有效

而with the composer himself staging it(错）因为composer是stage的主语，staging不是用来修饰composer的，作者是想表达主被动关系

with 的独立主格结构有两个易错点

1. with their doing 肯定错, 应该是 with sth (sb) doing,不能用所有格形式

2. with....it 肯定错, with已经表示伴随了, 再加it多余, 而且多数it有时没有指代对象

我觉得这道题B的用法with students growing and reaching语法上没错,但逻辑错误,本题的主谓语是 the number grow, 不是students grow, students怎么grow, 成了他们长大了.

但是第二条是OG紫皮13题：with the composer himself staging it我觉得是及物动词的话，就不能用这种独立主格结构，如果是不及物的话象上面with students growing and reaching就是对的，with+-ed/-ing这个ing相当于是修饰了student

另外那个选项except for a concert performance with the composer himself staging it也不能看成独立主格，因为没有逗号，如果是加了逗号except for a concert performance，with the composer himself staging it因为是及物所以这种独立主格错，从根本上就不能接doing it,但是我还是觉得应该要加个it，否则动词后面没有宾语了，记得有这么一个题的-_-||

一定要找到那道with 后加it的那个例子啊!我也想检验一下这条规律是不是放之四海而皆准.

刚找到一个这个http://forum.chasedream.com/dispbbs.asp?BoardID=23&ID=108599&replyID=&skin=1

里面有句

With a boy leading the way，they started towards the village．由一个小男孩领着路，他们朝那个村子去了。（现在分词）

看来是我错了，with+n.+ing(不及物及物都对),但是因为way和they不是同一个东东，所以就可以用way，而不能用them?with a boy leading them,they started....是错的就好象denny mm说的那样主语，with....it是错的

但是那道一定要把宾语重复一遍不知道在哪里看见过，可能不是with的，我再找找
