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! |
