4、当句子中出现了can时，动词一定要用原形。

now, am , is , are 这几个单词都是现在进行时的好朋友，当句子中出现了它们时，动词要用现在分词形式，也就是ing形式。

第六单元主要知识点：1、现在进行时的句子变一般疑问句时，只要将系动词be(am is are )和主语交换位置，将句末的句号变为问号，但是要注意第一人称和第二人称时，人称和系动词的相应变化。

如：I am reading a book? ------Are you reading a book?You’re walking . -----Am I waling? He is cooking dinner . -------Is he cooking dinner?2、表示用什么做个实验时，要用on。
