1. yours shoes are dirty .They need _D_badly.
A wash B washed C to wash D washing
它们急需清洗。washing是v-ing形式充当名词功能。
2. All the rooms in the house require_C_.
A clean B to clean C cleaning D cleaned
还是v-ing形式充当名词功能或者可以说成...require to be cleaned
3. You coat wants _A_. 。
A washing B to wash C washed Dbeing washed
v-ing形式充当名词功能 =to be washed
4. Much attention should be paid to _B_your handwriting, or you won’t get high marks.
A improve B improving C be improved Dbe improving
这道题含有这样的词组pay attention to doing sth/sth.这里的to是介词,后面应该接名词或者代词成分,而v-ing形式正好可以充当。

对“大师帮小弟解释一下”其他回答
前三个题用法应该是一样的 选dca
主语是物的时候 need/require/want + doing = need/require/want + to be done 记住吧
第四个是固定用法 还原过来就是 pay attention to + doing 选b
本人不是大师。。。。。
