题目内容

18．The teacher asked the boy，"Do you often do your homework with your classmates？"（改同义句）
The teacher asked the boyif he oftendid his homework with his classmates．

分析老师问男孩："你经常和你的同学们一起做作业吗？"
老师问男孩他是否经常和他的同学们一起做作业．

解答答案：if，did．这里是要求改成宾语从句，从句是一般疑问句，改为宾语从句用if作为引导词，表示是否，主句asked是一般过去时，故从句的一般现在时也要换成一般过去时，do 的过去式是did，故答案是if，did．

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．
