一、虚拟现在(Subjunctive Present):
虚拟现在的句子，在任何时候都要用动词的原形(root form)，就算是第三人称(he,she, it)也是如此。如：
1.1 现在时态(Simple Present): (右边为虚拟语气)
I work ---- I work
you work ---- you work
he works ---- he work (注意到了吗，是 work，不是 works)
she works ---- she work (不是 she works 喔）
it works ---- it work (同样不是 it works 喔)
we work ---- we work
they work ---- they work
1.2 现在进行时态(Present Continuous)右边为虚拟语气）
I am working ---- I be working (注意用的是 be，怪怪的!)
you are working ---- you be working
he is working ---- he be working
she is working ---- she be working
it is working ---- it be working
we are working ---- we be working
they are woring ---- they be working
1.3 现在完成时态(Present Perfect)右边为虚拟语气)
I have worked ---- I have worked
you have worked ---- you have worked
he has worked ----- he have worked (用的还是have喔)
she has worked ---- she have worked
it has worked ---- it have worked
we have worked ---- we have worked
they have worked ---- they have worked
1.4 现在完成进行时态(Present Perfect Continuous)右边为虚拟语气)
I have been working ---- I have been working
you have been working ---- you have been working
he has been working ---- he have been working (是 he have, 不是 he has )
she has been working ---- she have been working
it has been working --- it have been working
we have been working ---- we have been working
they have been working ---- they have been working
