plz translate these sentences in japanese.thankyou?

The sentences have been nonsense, yet right this is my version: a million.Pourquoi aider un autre will pay? Je ne le comprends vraiment pas.. 2. Rikion! On dirait que tu te plains? 3. Ce n'est rien grand-père! Je n'étais pas au sérieux, donc il ne faut pas t'inquiéter!"

娘　は　（－）　の　三年生　です。毎日　娘　は　いろんな　こと　を　習っています。私　は　よかったんです。

Musume wa __ no sannensei desu. Mainichi musume wa ironna koto wo naratteimasu. Watashi wa yokattan desu.

Then, in the blank spot, you put the kind of shcool she attends:

Grade school - Shogakkou　小学校

Middle school - Chuugakkou 中学校

High school - 高等学校

So say she was in third grade (elementary school.) You'd say this:

娘　は　小学校　の　三年生　です。　

Musume wa shougakkou no sannensei desu.

And then add the rest of it after that.
