I am qnite at a loss what to

I am qnite at a loss what to I am at a loss for ouraffection什么意思啊.. 英语 at a loss 与 at loss原来一直认为是有 at loss 这个短语 如 I `m at loss which to buy.可高考总复习上关于loss的归纳上却出现了 at a loss,如 I am at a loss what to do.和上面一样的结构 .两者等同么?没把 I am at a loss what to do 中what to do 做什么成分 who can it be i am quite at a loss to guess. I'm really at a loss! I am at.loss about .部分应该填什么啊 I do not know what I can do about it.I am completely at a loss 翻译一下这句话 there are five pairs to choose from,but i am at a loss which to buy 意思 at a loss 英语题there are five pairs to choose from ,but i am at a loss which to buythere are five pairs______,but i'm at a loss which to buy.choose from 为什么不能选for choosing there are five pairs to choose from ,but i am at a loss which to buythere are five pairs______,but i'm at a loss which to buy.choose from 为什么不能选for choosing I was a at a bit of a loss Sorry,this is my first time to make an IDD,call I am ____a.at a loss how to dob.at a loss to do c.at a loss what to dod.on a loss选C 为什么?需要解析和翻译 There are five pairs________,but I am at a loss which to buy.A to be chosen B to choose from C to choose D for choosing I'm completely at a loss怎么翻啊 两个副词啊at a loss是副词啊 there are five pairs __________There are five pairs __________,but I am at a loss which to buy.可以填for choosing吗,为什么?choose from. 当我不会语塞的时候就不隐身可以这么翻译吗：no hidden until i am never at a loss for the word 求正解
