5. [I] (+ adj.) to be in a particular condition or situation 处于（某种状态或情形）The house stood empty for a long time.那所房子空了好长一段时间。‘You're wrong about the date — it was 1988.’ ‘ I stand corrected (= accept that I was wrong).’“你把日期搞错了，是 1988 年。” “你说得对，是我搞错了。”You never know where you stand with her — one minute she's friendly, the next she'll hardly speak to you.你从来拿不准你和她的关系如何，她一会儿跟你亲热，一会儿连话也不大跟你说。As things stand, there is little chance of a quick settlement of the dispute.照目前的形势，尽快解决争端的可能微乎其微。
