Question

to do sth 和 for doing sth 有何区别
——I 'd like to buy an expensive camera.
——well,we have several models --------
a.to choose from b.for choosing

Answer 1

就这个题目而言,应该选a,
有许多型号可以从中选择,
若是要选b的话,那就要改成是for you to choose.
这样一解释你就可以明白了吧,其实没有for doing sth的,
这里是一个错误的选项.这里就是for sb to do sth,
当然,for doing sth也是会出现的,但是 不是固定搭配,只是那时候正好需要这样的结构而已.
说这么多,
不行的话,我们一起商讨一下啊
