(变否定句)→ He doesn't go to school at six in the morning。 3)对含有动词第三人称单数形式的句子提问时，要用助动词 does如： She goes home at five every day。 （对划线部分提问）→ When / What time does she go 注意： 不规则变化 : have--——-ha s , be —— - — -- — is ， do- — - — -does I 写出下列动词的第三人称单数（—s）和现在分词（—ing）go do play jump swim run put sing dance come get have fly study read write look drink eat walk like II 选择1.
