Hi, this is Yuyujin.

We have warm strong wind in Tokyo.
We don’t need heating today.

Today we learn “good at” and “poor at” in Japanese.
Let’s get started.

The basic patterns of “good at” and “poor at” are follows,
A Wa B Ga Jyouzu Desu(AはBがじょうずです。)
A Wa B Ga Heta Desu(AはBがへたです。)

A Wa B Ga Jyouzu Desu(AはBがじょうずです。)

Watashi Wa Uta Ga Jyouzu Desu
(わたしはうたがじょうずです。)
I am good at singing.

“Uta(うた)” means a song (noun).
But here “Uta(うた)” means “singing a song”.

Anata Wa Ryouri Ga Jyouzu Desu
(あなたはりょうりがじょうずです。)
You are good at cooking.

“Ryouri(りょうり )” means a dish and also cooking.

Kare Wa Tenisu Ga Jyouzu Desu Ka
(かれはテニスがじょうずですか。)
Is he good at tennis?

Hai Kare Wa Tenisu Ga Jyouzu Desu
(はい。かれはテニスがじょうずです。)
Yes, he is good at tennis.

Iie Kare Wa Tenisu Ga Jyouzu Dehaarimasen
(いいえ。かれはテニスがじょうずではありません。)
No, he is not good at tennis.

A Wa B Ga Heta Desu(AはBがへたです。)

Kanojyo Wa Unten Ga Heta Desu
(かのじょはうんてんがへたです。)
She is poor at driving.

Watashi Wa Chugokugo Ga Heta Desu
(わたしはちゅうごくごがへたです。)
I am poor at Chinese.

Watashi Wa Ryouri Ga Heta Desu
(わたしはりょうりがへたです。)
I am bad at cooking.

OK, that’s it.
Thank you so much.
Have a good trip!
