阁下请看句子: Time is one of the elements that Americans save carefully,the other being labor. 这句话中the other being labor 为什么用“being ”而不是用“be”? 劳驾您解释,谢谢! 打错了:为什么用“being ”而不是用“is”?
前面一句说完了the other being labor是状语从句 -ing 形式短语用作状语时,其逻辑上的主语(也和过去分词一样)必须与句子的主语一致。但有时它可以有自己的独立主语这种结构称为独立结构,它常由名词或代词主格担任,一般放-Ing形式短语之前。-ing形式短语结构多用于书面语,常表示时间原因条件方式或伴随情况。如: Spring coming on,the trees turned green. It being a fine day,I went swimming wiht John. He lay on his back,his glaring eyes looking straight upward.
