Today, I am going to share a homework correction from my Japanese Course!
The student’s sentence is not quite correct. Can you find the mistake?

 

[Student’s sentence]

 

このランプがついたとき、ボタンを押してください。

*このランプがついたとき、ボタンをおしてください。

 

 



 

 

[My correction]

 

このランプがついたとき、ボタンを押してください。
→このランプがついたら、ボタンを押してください。
When this light comes on, press the button.

 

When you want to express a sequence of actions, use 「AたらB」.
「AたらB」 means “When A happens, then do B” or “After A, do B.”

In contrast, 「AときB」 suggests that A and B happen at the same time.

 

Here are some more examples:

大阪駅(おおさかえき)に着(つ)いたら、電話(でんわ)します。
When I arrive at Osaka Station, I will call you.

 

ケーキをオーブンに入(い)れたら、20分待(ぷんま)ちましょう。
After putting the cake in the oven, let’s wait 20 minutes.

 

I hope my explanation helps you.😊

 

I interact like the above correction with my JLPT All-in-One Course student. (Today’s homework sentence is from the N4, elementary level. Not sure of your Japanese level? Then take a level test here.) I can explain in English or Japanese, depending on your level.
