“I love cat”这句话到底有什么问题呢？

当你想要谈论整个类别的东西时（不单指某一个具体的事物）比如动物，就用复数。

否则，如果用动物的单数形式，像是在描述动物的肉。

A： I love cat. Cat is so cute.

B：Oh, you mean you love cats?

A：Yes, but I don't dog.

B：I don't like dogs. When you want to talk about a thing in general, like an animal, you need to use the plural form. Cats, dogs.

A：Oh~

B：If you use the singular form of an animal, it often sounds like you're talking about the meat from that animal.

A：OK. So I like eating cow. Yes？

B：Well, if you want to talk about cow meat, we say beef.

A： Okay. Okay. I like duck. It means I like to eat a duck. Yes?

B: Oh, me too.

A: But I hate gooses. They scare the shit out of me. GOOSES. See, I put the "S". So I'm talking about the animal, right?

B: Actually, the plural form of goose is geese. So if you want to talk about the animal, you can say "I hate geese".

A: I hate English.

B: Perfect.

A: Okay, I got it.

I love cats.

I don't like dogs.

I like eating beef and duck.

I hate geese.
