uncountable nouns後的be點用?

如果那句句子的tense是present tense便用is,如果那句句子的tense是past tense便用was.
The homework (is/are) finished.應該用is.

It should be :

The homework has been finished.

Because homework is uncountable ,
so we propery use is .

But because finished ,
that means it has already finished .

Therefore , I use present perfert tense .

Be -----> Has + Been



Hope can help you ^^

The homework was finished.因為the是一個，而finished是過去或，所以用was。

I believe you have asked a very good question about uncountable nouns and can they actually be counted by any chance in a plural form.

Ok, I'm thinking about this...

Let's first to tackle the simplest first, when we say a noun is uncountable it means it can't be enumerated by adding a number to it for example :

One water or two water and so on...(x) which don't make sense.

However, if we bottled them, we could actual count them by the number of bottles, right? What if we further coloured the water into red, blue and green just for the sake of distinguishing them in different colours; we could have actually say : there are 2 bottles of blue coloured water, 2 bottles of red coloured water and 3 bottle of green. All these coloured waters are filled in different bottles. Hey! you know what? I think it's possible to pluralize any uncountable noun if you can further split them into different unit/forms that's countable and then collectively named them as a plural noun.

Think I've made a discovery but I'm not sure if I'm right.. I'll try to ask around for opinion if I got the chance.
Thanks...for asking, sorry for not answering I'm a little berserk lately..
