答案是c, d中的with一般在什么情况下用啊？

如果你用-ing and -ing 这就表示出这两个动作同时发生， 但是~按照逻辑意思理解，是前者导致后者。所以不能那么用。

你去论坛上搜with的帖子~ with做独立主格一般用得不是很多~你这句话是要修饰ｐｒｏｆｉｔ～　不能用ｗｉｔｈ做状语了～定语和状语不是一个性质上的东西啦~

kimfeng

with 有两种用法：
(1)with+n 的介宾短语做状语或定语
(2)with+n+-ing/-ed/adj/介宾短语等做独立主格结构。独立主格只做状语，表伴随，仅用于修饰主谓宾结构主句的谓语动词。如 The murderer was brought in, with his hands tied behind his back。

第一题同楼上

上面两种情况的区别在于，(1)只是一个短语，而(2)with后的部分有句子的意思，即动词的形式被修改了，去掉的句子的特性。稍微修改，就能把with后的部分还原为一个句子（如加上be动词或把ing换为原型）
（注，with后决不能跟句子）

D、E选项中，with引导的是一个独立主格结构，而主句是主系表结构，主语The results没有发出一个动作，所以with没办法去伴随谁。而正确答案用的是which引导的非限制性定语从句，解释这个利润怎样怎样。
