一般现在时：A flies away, as B do.过去时： A flew away, as B did.

别的时态我就不确定应该怎么表达了，是下面这样的么。
将来时： A will fly away, as B will do.
现在进行时：A is flying away, as B doing. (是这样么。。。好奇怪啊。。。)
现在完成时：A has flown away, as B has done.
过去完成时：A had flown away, as B had done.

LZ~Manhattan Chapter13最开始就是专门讲Helping Verbs的~你可以去看看~
另外我觉得现在进行时那个是is，完成时的done都可以省略~~~
