I had to be treated with radiation following by treatment with chemicals.答案是把following改為followed,為什么這樣改,原句哪兒錯了?現在分詞和過去分詞有哪些區別啊,我老是分不清.

熱心網友

與本題相關的現在分詞和過去分詞的區別是：現在分詞表示主動，過去分詞表示被動。關鍵在于找準邏輯主語才能準確判斷主動還是被動，本句邏輯主語是treatment with radiation放療 （=treated with radiation） 它被treatment with chemicals化療所跟隨,是被動關系.所以用followed.
