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

 

[Student’s sentence]

大人になって、ゲームをしないようになりました。

*おとなになって、ゲームをしないようになりました。

[My correction]

大人になって、ゲームをしないようになりました。
→大人になって、ゲームをしなくなりました。
As an adult, I no longer play games.

 

Negative changes for ようになる take the form 〜なく＋なる.
That’s because nai-form(~ない) is conjugated in the same way as i-adjectives.

i-adj(removeい)く＋なる,
しない is a nai-form of する
＝しな(removeい)く＋なる
＝しなくなりました; past tense, polite style

ように is only added before 〜なる(become) when connecting the verb dictionary-form to なる.

e.g.
子(こ)どもが野菜(やさい)を食べるようになりました。
The child has started to eat vegetables.

年(とし)をとって、肉(にく)を食べなくなりました。
As I got older, I stopped eating meat.

息子(むすこ)は大学生(だいがくせい)になり、バイクに乗(の)るようになりました。
My son became a college student and started riding a motorcycle.

東京(とうきょう)に住(す)んでから、車(くるま)に乗らなくなりました。
Since living in Tokyo, I no longer drive a car.

 

I hope my explanation helps you. 😊
