"我要跟你商量一件事情。"

Translation: I need to discuss something with you.

[hippietrail]

Would the Chinese be different for "I want to discuss ..." than for "I have to/need to discuss ..."?

[Cinnamon5230]

Yes, since 要 can be both "want" and "will", you need to replace it with other words.

我想…… I want to ...

我需要…… I need to ...

我必须…… I have to ...

[hippietrail]

So does that mean that this question can also correctly be translated into "I want to discuss something with you"?

[brian.g.chen]

"have to/need to" would be more like 需要. If you put "want to", it should have been accepted.

[KX3.]

"I want to discuss something with you" is accepted.

Dong wu is not suitable?

[BobbyTable2]

I don't believe so. 动物 (Dòngwù) means "animal"
