"My father does not have a younger sister."

Translation: 我的爸爸没有妹妹。

[and.kelley.love]

的 is unnecessary

[Jo-AnnHan]

我的 爸爸 不 有妹妹 is incorrect. Why? I thought that 不 negates the verb.

[valiendomother]

When it comes to the verb Have (有yǒu) and negation 不 bù is not used, instead it's 没有méiyǒu.

Ex:
1. I don't drink tea (我不喝茶 Wǒ bù hē chá)
2. I don't have tea (我没有茶 Wǒ méiyǒu chá)

[AndrewPfaff]

Also 我没喝茶 I didn't drink tea

Can anyone please explain why family members have their symbols twice?

[DatSovietAlexso]

They can also be used just once, it is mainly for convenience.

[AndyB8864]

And also you can't say 我的爸爸, you don't need 的

[whale-shark]

我的爸爸没有一个妹妹 was marked up as being wrong, not quite sure why can someone help please?

[HaydenMiner]

Using 一个(yīgè) would specifically state that your father does not have ONE younger sister. In that case maybe you would say "He doesn't have one, he has four!"
我的爸爸没有妹妹 is how you say that he has none at all. Although in English when we use the article "a" it typically means one of something, in this case we mean that he doesn't have any at all.

I think duolingo courses is not pretty correct 100% the grammar is too rigid. Do you think the way as i do?

[Joy931]

I've said this with many other lessons- adding "一个" should be acceped! It literally says "does not have A younger sister" not "does not have younger sister"

[DheerajBhaskar]

When to use which 没 vs 没有。Is 没 used alone?

[DatSovietAlexso]

Just 没 is used to say "no" in the past tense, like 昨天我没上课了

[Joy931]

I put : 我的爸爸没有一个妹妹
Duolingo said that was wrong even though it says "does not have A younger sister"
