2.If not _____________a lift on her way,Jerry couldn't have got to the station in time.( 。
A.offeredB.to be offeredC.offeringD.to offer

分析 如果沒有人讓她搭便車,Jerry 不可能及時到達車站.

解答 答案是A.本題考查"連詞+分詞"的結(jié)構(gòu)."連詞+分詞"的結(jié)構(gòu)在句中往往做狀語,相當于狀語從句,屬于分詞做狀語;分詞做狀語時分詞的選擇是看分詞和句子主語之間的關(guān)系:分詞和句子主語之間是主謂關(guān)系(主動關(guān)系),用現(xiàn)在分詞;分詞和句子主語之間是動賓關(guān)系(被動關(guān)系),用過去分詞;本題中連詞if后的not offer 和句子主語Jerry之間是被動關(guān)系,所以答案選擇A.

點評 在非謂語動詞的解題中要在掌握其基本用法的基礎(chǔ)上關(guān)注并積累一些固定用法,并結(jié)合具體語境做出合理的判斷.
