The present perfect tense is a grammar point whose steps must be taught earlier.
In Japan, students start learning it in the 3rd year of junior high school, which I think is too late.

最終的な英文は下記の通りになります。

The present perfect tense should be taught a lot earlier.
(日本の学校では)現在完了形はもっと早い段階で教えるべき文法だ - The present perfect tense should be taught a lot earlier (at Japanese schools)になります。
日本人では中学3年生の時に習うそうです。遅いと思います。
Apparently, Japanese students learn about the present perfect (tense) in their 3rd year of secondary school/junior high school. I think it’s (far) too late.
気持ちや状況を伝える上で大事な文法だと思うのでもっと早い段階で教えるべきだと思います - The present perfect tense is very important, as it can be used when talking about one's feelings or the state of things, so I think it should be taught a lot earlier at schools.
