to be done 与 to doing
以前做了一道题,但记不太清了,里面大概好像是说
某些时候to be done=to doing

to doing的结构存在,但是决定其结构的是前面的动词或者介词e.g.:look forward to doing,此结构只做特殊用法,而其意义在于V.+sth,至于to be done 可理解为不定时的被动式,可以从下列句子分清楚:
It is to be built.
It is to building.
二者本身各不相同,其等于情况在张道真的最新语法书中已被删除

to be done 与 to doing to be done=doing? want to be done与want doing的区别 being done 和 be doing ;done ；doing ; be done ;to be done 的用法为什么有doing=to be done need doing 和need to be done be worth doing 与be worth to be done的区别? 英语区分 doing to和 be doing,being done 和 to be being done . need to be done与need to doing的区别是什么? 怎么区分谓语动词,to do doing done 和to be doing to be done to have do be worth doing等于be worth to being done吗 to do / to be doing / to have done / to have been doing/doin
