4．(2011·陕西高考)I ______through that bitter period without your generous help. A．couldnt have gone B．didnt go C．wouldnt go D．hadnt gone 解析：考查虚拟语气。英语中， without, with, or, otherwise 等可构成含蓄虚拟语气，此处without your generous help相当于条件状语从句“If it hadn‘t been your generous help”，表示与过去事实相反，此时句中的谓语动词应用should/could/would ＋have＋过去分词。据此可知选A项。句意：假如当时没有您慷慨相助，我就不会度过那段艰难的时期。 答案：A 5．(2010·天津高考)—John went to the hospital alone. —If he ________ me about it，I would have gone with him.
