Today I am going to share the homework correction quoted from my JLPT N4 course!
The student’s sentence is not correct. Can you find the mistake?

 

[Student’s sentence]

あれ？電気がつけていますね。さっき消したのに。

*あれ？でんきがつけていますね。さっきけしたのに。

[My correction]

あれ？電気がつけていますね。さっき消したのに。
→あれ？電気がついていますね。さっき消したのに。
Huh? The light is on. I turned it off a while ago.

ついて is a te-form of つく(intransitive verb), つけて is a te-form of つける(transitive verb).

[transitive verb]ている indicates when the action is in progress or someone’s routine. On the other hand, [intransitive verb]ている indicates the result of a change.

This sentence indicates that someone turned on the light and that light is still on, so [intransitive verb]ている＝ついている is used.

 

e.g.
田中(たなか)さんは、今(いま)勉強(べんきょう)しています。

Tanaka-san is studying right now.

[transitive verb＝勉強して]いる

 

まどが割(わ)れています。

The window is broken.

[intransitive verb＝割れて]いる

 

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 as much as you want. I will teach you until you get it!
