choose from,pick up

题目

choose from,pick up
there are so many kinds of TV programs that i don't know _________
A which to choose from
B which to pick up
这题怎么是选B 呢 而且pick up 的意思又不是挑选,pick out 才是
说说A咋错了 many kinds of 不算范围吗?
书上有例句：there are plenty of restaurants to choose from .
按你们说的书上那例句后面也没有宾语啊
programs不就是choose from 的宾语吗

答案

pick up有很多意思,可以意译成挑选.A答案中choose from后要接宾语,而答案没有,所以,A为语法错误.如果把from删去,choose作为不及物动词,其后不用接宾语,就是正确答案了.
