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
答
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。
答
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.
答
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?
答
polishing
sth need doing = sth be needed to do
