(2)I________ (g)thrugh that bitter perid withut yur generus help.答案：culdn't have gne 考查虚拟语气。句意：如果没有你们慷慨相助，我不可能度过那段艰辛的岁月。表达与过去事实相反的虚拟时，主句常用“wuld/culd/shuld/might＋have dne”。
(3)We________ (put)Jhn's name n the race list yesterday but fr his recent injury.答案：wuld have put 考查虚拟语气。句意：要不是因为约翰最近受伤的缘故，我们昨天就把他的名字写在参赛名单上了。根据句意及but fr(倘若没有，要不是)可知，这里考查针对过去的虚拟，所以主句谓语部分要由wuld/culd/might/shuld＋have dne的形式构成。
