大师帮小弟解释一下1.yours
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 ...全部

3。 You coat wants _A_。 。

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。
