单选题
There seemed little hope that the explorers, _____ in the rainforest, would find their way out.
Ahaving deserted
Bto have been deserted
Cto be deserted
Dhaving been deserted
正确答案
答案解析
此句中having been deserted用于描述explorers的状态，是已经被遗弃在雨林里。选项A中缺少被动态，可以排除。to do表示打算、计划做，to have done则是表示本来打算做但实际上没做，是虚拟语气的用法。因此选项B和C都可以排除。余下的选项D为正确答案。
