题目内容
6.If youhad joined(join) the chat room ten minutes ago,you would have known what we were talking about.分析 如果十分钟之前你加入了聊天室,你就知道我们在讨论什么了.
解答 答案:had joined
解析:根据句意"如果十分钟之前你加入了聊天室"可知本句使用了虚拟语气,又根据后面的would have known可知本题考查If sb had done,sb would have done"如果某人做了…,某人就会…"这一虚拟语气的使用(其中if引导的条件状语从句是对过去的虚拟).综上,本题答案为had joined.
点评 本题考查单词填空,做此类题目时一定要仔细分析句子结构,根据所给词从语法、句意、时态等各方面判断所填词的正确形式.
