whereas 用法

qiufeng1990

Most large companies prefer customized computer software because it can be molded to fit the way a company does business, （whereas） off-the-shelf software often requires the company to alter its procedures to fit the software.

B) because
C) while

这三个词有什莫区别？

是我编的，现在明白多了。
斑竹辛苦了，睡个好觉。多谢了。

我认为whereas在这里比较好。B，简直是乱来。是兄弟你临时编出来的吧？
到是C 有些迷惑，因为while 有强对比的用处。但再读一遍题目，觉得若划线部分后的主语改成most little companies 用while就比较顺畅。
其他的明天再与你讨论，现在得睡了。
