1 (主动或不及物) having done,doing和to be doing的对应形式是（被动）having been done,being done和to be being done
2 done的对应形式绝对不是doing：
Done well / Well done,the work pleases the boss a lot .-------- 强调“被动”的概念.
Doing his work busily,the workman can't go out for lunch.--------强调“主动”的概念,表达“正在- -- ”
Sleeping soundly in his room,he didn't hear or see what was happening outside --------强调“正在- -- ”,属于不及物.
Being repaired at the moment,my car isn't available for use.--------强调“正在被- - - ”,属于及物.
还有问题吗?
再问： 1doing表示现在正在发生，及对应现在发生的被动——being done
2:to be done这种被动形式是不是表示将要发生的被动？那它对应的主动形式又是什么呢（即表示将要发生的主动形式又是什么）？
3done与having been done都表示已经完成的被动，那二者又有什么区别呢？
4如果having done对应having been done，那done对应的主动形式又是什么呢？
再答： 1doing表示现在正在发生，及对应现在发生的被动——being done ------ 对。
Doing his work, he isn't able to come out for you.
Being done now, the design is not yet ready.
2 :to be done这种被动形式是不是表示将要发生的被动？那它对应的主动形式又是什么呢---------
A 往往出现在复合谓语里面：
His work seems to be well done ------- He seems to do his work well.
B 表将来，做定语：
The work to be done tomorrow is important and has to be done carefully.
The man to do the work next week is from the government
3 done与having been done都表示已经完成的被动，那二者又有什么区别呢？
Built 40 years ago, this bridge needs rebuilding == This bridge, built 40 years ago, needs rebuilding --------done的形式在我看来，是定语前置/定语前移。
Hving been built for 40 years, this bridge still looks good and modern. -------- having been done的形式是做状语结构。
