He is writing his homework now. 现在他正在写他的作业。现在进行时谓语动词的变化形式：be+ v-ing.

注意：动词ing形式的变化规则：

1）一般在词后直接加-ing 例词：

go---going walk---walking do---doing talk---talking

2)以e结尾的去e加-ing 例词：

write---writing take---taking leave---leaving

3)以辅音字母+元音字母+辅音字母结尾的重读闭音节，双写末尾辅音字母，再加ing

例词：

shop---shopping stop---stopping sit---sitting get---getting 4)不规则变化：lie---lying

如果表达某人是否正在做某事，则要用现在进行时态的疑问句了。句式结构：Be+主语+动词ing形式+....
