Question

want to do和want doing有什么不同

Answer 1

want to do多表示临时想到要做的一件事情，want doing带有一种爱好的成分。

I want to eat for I am feeling hungry. 我感到饿了想吃点东西。（想吃东西只是感觉到饿的结果）
I want eating a big meal. 我想吃大餐。（心里一直有这个想法）
如果是 I want to eat a big meal.则更多是表示我突然好想吃大餐了。

Answer 3

人作主语时：
want to do sth. 想要做...
want sb. to do sth. 希望(人)做...
want sth. done 希望（物）被...

物作主语时：
sth. want doing ，这时候的want，意思是“必须，应该”，相当于need。这里的doing有被动的意思，相当于to be done.
如，Your hands want/need washing. 你的手应该洗洗。

Answer 4

want to do. 想要做某事，主语一般为sb. I want to go to Beijing.
want doing, 一般是物作主语，意为：某物需要……可以互换为 want to be done
如： The table wants cleaning= The table wants to be cleaned.

祝你学习进步！

Answer 5

want 后面通常接不定式,即 want to do sth
I want to have a look at your new watch；
有一种情况下可接动名词的主动式 ：want doing ,但这种情况下,doing与句子的主语成动宾关系,也可由 to be done代替；
例如：The flowers want watering/to be watered.花儿需要浇水.
