问题描述:

my shoes are so dirty that they need polished这句话对吗?是用polished形式还是polishing?急

应该用polishing, need 这个单词比较特殊,它后面接被动语态的词要用ing形式代替过去分词。

应该用polishing
sth. needs doing = sth. needs to be done.
你也可以说:
My shoes are so dirty that they need to be polished.

你好,有两个句型来解答.1. sth needs /wants /requires doing. 2.sth needs/ wants /requires to be done. 看例句:You need to polish your shoes=Your shoes need to be polished=Your shoes need polishing. 再如:We need to repair our house.=Our house needs /wants /requires repairing=Our house wants /needs/ requires to be repaired. 明白了吗?

polishing
sth need doing = sth be needed to do
