Hi, there😆 I love sports. In Japan, baseball and football are popular.
🇯🇵Recently, I love to American football. 🏈American football is a very popular
sport in America, but it is not known in Japan. There is a top league in Japan,
too. Watching a game is very exciting . 🏟I hope it becomes popular in Japan
too.😫
私はスポーツが大好きです。日本では野球やサッカーが人気です。私は最近、アメリカンフットボールが好きになりました。アメリカンフットボールはアメリカでは大人気のスポーツですが、日本ではあまり知られていません。日本にもトップリーグがあるんですよ。試合を観戦するとすごい迫力ですね。日本でも人気が出ると良いなぁ
Use a comma to split a sentence into separate clauses.
My dog, which is a dachshund, bit me.
You could just say
My dog bit me - the middle of the sentence is additional information.
I am sixteen, however I'm not allowed to vote.
I'm a native speaker so I'm crap on grammar but I can tell you what looks right and what doesn't and you'll pick that up with practice.
