比较:Now I put the sugar in the cup.
I am doing my homework now.
第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作.再如:Now watch me,I switch on the current and stand back.第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时.
上面说的对吗?第二句中的NOW表示进行时的标志 怎么说用一般现在时?

你的理解是正确的..
口语中不计较语法,按理说这两句用现在进行时和一般现在时都不错,只是通常第二句用现在进行时,因为做homework这个动作是延续性的,不像第1句那个动作是可以一下子就完成的,所以通常第2句用现在进行时~
