题目内容
2．Did they have a good journey home？Do you know？（改为含有宾语从句的句子）Do you knowif theyhad a good journey home？
分析 你知道吗？他们是否有个愉快的回家之旅？
你知道他们是否有个愉快的回家之旅吗？
解答 答案：if，had．
根据题意将原句合成一个宾语从句，作为know的宾语，一般疑问句Did they have a good journey home作为宾语从句，英语一般疑问句变为宾语从句一般要用if或者whether做引导词，后面紧跟主语谓语，Do you know是一般现在时，故从句的一般过去时不变，故had，故答案是：if，had．
点评 本题旨在考查宾语从句这一语法，做这类题时，要从三方面考虑：一、选准连接词 二、连接词后紧跟从句的主语 三、若主句是过去时，从句要改为相对应的过去时．
