Having been 是什么时态
Having been lost in the mountains for a week ,the two students were finally saved by the local police.
为什么不是 have been lost
Having been lost in the mountains for a week ,the two students were finally saved by the local police.
为什么不是 have been lost
你不要被having 的ing 迷惑住,其实就是现在完成时,只不过做了伴随状语,需要用ing形式来修饰the two students , 所以它的原形就是have been ,
原句可以改成,The two students have been lost in the mountains for a week ,the two students were finally saved by the local police.
只不过为了简便,所以第一句成了修饰成分.
明白了?呵呵
