英语语法考点梳理：现在进行时

现在进行时：表示现在正在进行的动作 构成： 主语＋be动词＋动词的现在分词＋其它成分 He is reading a book. The dog is running after a cat. The boys are swimming across the river. 变疑问句将be动词移到句首 Are we having lunch? Is he reading a book? Is the dog running after a cat? Are the boys swimming across the river? 变否定句在be动词后面加 not We are not having lunch. He is not reading a book. The dog is not running after a cat. The boys are swimming across the river. 特殊疑问句：what, which, how, where, who, etc. 疑问词＋动词＋主语＋现在分词 What are you doing? What is she doing? What is the dog doing? 没有进行时的动词 表示状态，思想，感情和感觉的动词不能表示正在进行的动作 1. 表示感觉，感官的词 e, hear, like, love, want, 2. have, has当”拥有”讲时没有进行时
