interesting article!


but, 时态, is often useful.

however, 时态 has been abused.

the good way to do is:

1. for example, all past sense should be added with an "ed"; other forms are nop longer accepted, coz they just bring confusion

2. default, default, default, default, default: when you the time sense isn't important, use the standard form, when it is important, use specific sense (such as past sense)
also, the item means the present sense have to be different from the standard sense
