Today I am going to share the homework correction quoted from my JLPT N5 course!
The student’s sentence is not correct. Can you find the mistake?

 

[Student’s sentence]

日本に一番高い山は富士山です。

*にほんにいちばんたかいやまはふじさんです。

[My correction]

日本に一番高い山は富士山です。
→日本で一番高い山は富士山です。
The highest mountain in Japan is Mt. Fuji.

 

Particle で can be used to specify a range.
In your sentence, で marks 日本 as the range being discussed.

 

e.g.
このクラスで一人(ひとり)だけフランス語(ご)が話(はな)せます。
Only one student in this class speaks French.

英語(えいご)は世界中(せかいじゅう)で勉強(べんきょう)されています。
English is studied all over the world.

彼女(かのじょ)と結婚(けっこん)できて、人生(じんせい)で一番うれしい。
I am the happiest I’ve ever been in my life to be married to her.

 

 

I hope my explanation helps you. 😊

 

In the JLPT course, all lessons come with homework. If you submit your homework, I will reply with corrections.
I can break down the Japanese grammar and point out mistakes, explaining the structure and nuances of Japanese in an easy-to-understand way.
You can also ask me any questions in as much detail as you want. I will teach you until you get it!
