1、B.因为主句用的是一般过去时态,所又从句应该也是过去时态,排除D,而从句缺少的是谓语动词,而A、C都是非谓语动词,故只有B可选.句意：我们听到这则好消息时都很激动.2、D.全句可以这样重写：As he did not realize t...When _____ the good news,we were all excited. A hearing B heard C to hear D hear那这个呢？我不是在1中回答选B了么？你回答的是When we_____ the good news,we were all excited.Ahearing BheardC to hear Dhear我问的是When _____ the good news,we were all excited. A hearing B heard C to hear D hear嘿嘿。。。呵呵，选A。为什么呢具体分析下好吗 谢谢啦在同时省略连词、主语的从句中，把连词带上也符合语法。先采纳我的答案中不？
