whether引导让步状语从句时,该如何倒装?
省略whether的虚拟让步状语从句中需要倒装。若是系动词,则把系动词放在主语前。若表语是名词,则去掉其前的不定冠词。若从句谓语是实义动词,常省略主语,只保留谓语动词原形。
whether引导让步状语从句时,如:Whether it be bird, fish, or beast, the porpoise is intrigued with anything that is alive。
但是在Longman中,whether表让步是可以接一般式,过去式。如:It seemed to me that she was in trouble whether Mahoney lived or died。
