to choose
which one to choose是wh- to do 结构,不是从句.
1.该结构起名词作用,作主语、宾语、表语、同位语.
I didn't know how to choose .
2.wh-词如果是副词,如where\when\how等,作to do 的状语；如果是代词,如what\whose 等,作to do 的宾语或宾语的定语.
I don't know which book to choose.
I don't know what to choose.

I don,t know which one _____ （choose) I really don't know which one to choose i don't know choose which one为什么不对? i don't know which one to choose I don't know which sweater _____(choose) I don't know which watch _____(choose). I don't konw which one i will choose.I don't know _________o I don't know choose which one.哪里错了?那为什么 I can't choose which i don't know which one to choose.请造几个类似which ...to 的句子 i don't know which one/which to choose选哪一个,为什么?再举例几个 i don't know which one to choose.中Iwhich one 是KNOW的宾语 ,那么to I don't know which sweater to choose.动名词
