英语题there are five pairs to choose from ,but i am at a loss which to buy
there are five pairs______,but i'm at a loss which to buy.
choose from
为什么不能选for choosing

从。。。当中挑选 应该表述成choose from...
你说的那种缺少介词,所以不对

to 表示不定式.虽然for+v-ing也是对的,但是用to choose form更好些.

to表目的,去选择。同时choose from表示有范围的选择。前面有five pairs,就是范围。

也是可以的

to choose表示一个动作
for choosing表示状态
所以不能选
to do为不定式

主语不是人,所以不能用for choosing,for choosing,for谁choose呢?对吧?
