  新概念英语第一册语法知识点之现在进行时:
          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(现在分词的构成见附录)
          We are having lunch.
          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(必背)
          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
          see, hear, like, love, want,
          2. have, has当”拥有”讲时没有进行时
