答案和解析
时态由“时”和“态”构成.“时”主要有四个主要部分,即现在、过去、将来和过去将来;“态”也有四种,即一般、进行、完成和完成进行.将四个“时”和四个“态”组合在一起,就是时态的种类,共十六种.为使学习者能够直观地看到时态的现象,现以work为例,将这十六种时态如下:
一般现在时:work / works
一般过去时:worked
一般将来时:shall / will work
一般过去将来时:should / would work
现在进行时:is / am / are working
过去进行时:was / were working
将来进行时:shall / will be working
过去将来进行时:should / would be working
现在完成时:have / has worked
过去完成时:had worked
将来完成时:shall / will have worked
过去将来完成时:should / would have worked
现在完成进行时:have / has been working
过去完成进行时:had been working
将来完成进行时:shall / will have been working
过去将来完成进行时:should / would have been working
一般现在时:work / works
一般过去时:worked
一般将来时:shall / will work
一般过去将来时:should / would work
现在进行时:is / am / are working
过去进行时:was / were working
将来进行时:shall / will be working
过去将来进行时:should / would be working
现在完成时:have / has worked
过去完成时:had worked
将来完成时:shall / will have worked
过去将来完成时:should / would have worked
现在完成进行时:have / has been working
过去完成进行时:had been working
将来完成进行时:shall / will have been working
过去将来完成进行时:should / would have been working
