I have yet to find the answer.= I have not as yet found the answer. have yet to 是只能用于主动的动作, 比如I have yet to make a decision. 还是可用于非主动的情况, 比如I have yet to find the answer. have yet to 有还差什么没做的意思?
I have yet to find the answer.跟I have not as yet found the answer.的意思是一样的,即“我还没有找到答案.”这两种说法都是正确的. I have yet to find the answer.好像不是非主动的情况.你对“非主动”的定义是什么? 回答补充: have yet to本意就是“还没(做)……”,所以可以引申为“还差……没做”,有这个意思.
