mine.我走在街上的時候,遇到了一位老朋友。(walking和謂語動詞met同時發(fā)生)(2)當(dāng)表示的動作先發(fā)生,而謂語動詞的動作后發(fā)生時,用動詞-ing的完成式。Having finished the letter,he went to post it.他寫完信后就把它寄了出去。(having finished是先發(fā)生的,went是后發(fā)生的)2.語態(tài)使用動詞-ing的主動式還是被動式,主要取決于它和句子主語之間的關(guān)系。表示主動關(guān)系就用主動式,表示被動關(guān)系就用被動式。Having been shown around the factory,they were very
