18. Computers are becoming faster, more powerful, and more reliable, and so too are modems, they are the
devices to allow two or more computers to share information over regular telephone lines.
(A) so too are modems, they are the devices to allow
(B) so too are modems, the devices that allow
(C) so too modems, the devices allowing
(D) also modems, they are the devices that allow
(E) also modems, which are the devices to allow
答案是B,没有问题
但是OG解释说To allow is not an idiomatic way to modify devices; either that allow or allowing would be correct.
我的问题是:
1. device用to allow修饰为什么不好?to = in order to表示目的,就是说这个设备的目的是。。。为什么不对呢?
2.为什么device用allowing 修饰可以?allowing可以用作解释前面的名词?我觉得doing修饰前面的名词,一般表示重复的动作?
谢谢各位指点!
谢谢niswzzhn
你说得对!有些语法点我是不能记得太绝对了,先记住ets曾经这么解释过。我想选出正确答案的时候,肯定不会就依靠这么一个知识点作为区分,即使是,也应该是你说的那种情况:是在devices allowing和devices allowed比较的时候用
关于device to allow,我还没太明白用这种方式,意思上如何不同了?多谢再指点一下!
