有時(shí)為使分詞短語(yǔ)與主句關(guān)系更清楚,可在分詞前加連詞。 連詞有: when,while,if though,after, before, as. 但分詞的主語(yǔ)和主句的主語(yǔ)必須為同一個(gè),如:
While waiting there, he saw two pretty girls come out of the building.
waiting 和saw 的主語(yǔ)相同。
While waiting there, he saw two pretty girls come out of the building.
waiting 和saw 的主語(yǔ)相同。
