Do引导的一般疑问句及其回答高频易错点02 1. 一般现在时中，当句子以实义动词(如eat、play、study等表示具体动作的词) 作谓语时，若要表达“询问 动作是否发生”，必须用Do/Does作为助动词引导一般疑问句。 2. 当主语是第一人称(I, we)、第二人称(you)或者第三人称复数(they, my friends, these cats)时，助 动词用do. 3. 句型结构：—Do+主语+动词原形+其他？—Yes,主语+ do.No,主语+ don't. 例句：—Do you like dogs?你喜欢狗吗？ —Yes,I do.是的，我喜欢。/ No,I don't.不，我不喜欢。 易错点提示 注意区分： 1.当主语是第三人称单数(he, she, it, Tom, the boy, my mother,a bird)时，助动词用does. 2.当主语是不可数名词(water, rice...)时，助动词用does. 3.句型结构：—Does+主语+动词原形+其他？—Yes,主语+ does.No,主语+ doesn't. 例句：—Does he often sing songs?他经常唱歌吗？ —Yes, he does.是的，他经常唱。/No, he doesn't.不，他不经常唱。 经典例题 ( )1. —_________ you like rabbits? —Yes, I do.
