选lost吧..
就是非谓语,你写作文也可以用的,被动ed,表示状态
having been lost 这个表示现在完成进行时,你自己推一下,显然不对,因为题上后面是were
having lost 也是这个情况
being lost...就是规定,没这个形式
in the mountains for a week ,the two students were finally saved by the local police
in the mountains for a week ,the two students were finally saved by the local police
A Having lost B lost C being lost D losing
有几种大家回答的比较多的答案,having been lost ,lost,having lost ,
还有,为什么不可以用being lost?
A Having lost B lost C being lost D losing
有几种大家回答的比较多的答案,having been lost ,lost,having lost ,
还有,为什么不可以用being lost?
