Usage of に in たくさん人参を食べると、きれいになります。


Is this right:

> たくさん[人参]{にんじん}を[食]{た}べると、きれい **に** なります。

Was に used correctly?

The example sentence I saw was:

> たくさんピザを食べると、おおきくなりますが、いつもスポーツをすることが好きです。

Thank you!




I believe you are wondering if the use of に in the first sentence is correct
because the second sentence is not using に in a sentence that seems similar to
the first one.

First of all, these two sentences are both correct. Only the difference is
that the first one is written in hiragana only, and the second one is written
with some kanji.

> たくさん[人参]{にんじん}を[食]{た}べると、きれいになります

Now, let's look at the second sentence (Forget the last part of this sentence
because it's not related in this case)

> たくさんピザを食べると、おおきくなります (correct)

The reason why you don't say

> おおきい に なります (wrong)

in this case is because `おおきい` is an i-adjective.

Here's the rules for `become`:

> If it becomes i-adjective （おおきい、ちいさい、ながい、etc), replace the last `い` with `く`
>
> Examples:
>
> おおきく なります
>
> ちいさく なります
>
> If it becomes na-adjective （きれい、しずか、べんり、etc), just add `に` before `なります`
>
> Examples:
>
> きれいに なります
>
> しずかに なります

So, the following two sentences are both **grammatically** correct.

> たくさん人参を食べると、きれいになります
>
> たくさんピザを食べると、おおきくなります
