then why I still need a knife to eat an apple although I don’t peel it.

**Why do I still need a knife to eat an apple, even though I didn't peel it.

first of all, I cannot finish the whole at one time, I get tired of the taste halfway.

**First of all, I can not finish the whole apple. I get tired of the taste halfway through.

and I don’t want to leave it bitten off, I cut a third or fourth out of it with a knife before I eat it.

**I don't want to leave it with a bite taken out. So I cut it into thirds or fourths with a knife before I eat it.

also I don’t eat it from outside to the core part which doesn’t taste as good to me.

**Also, I don't eat it from the outside to the core. The core doesn't taste good to me.

I want to finish at the tasty part, so I get rid of the core beforehand.

**I get rid of the core before I finish the apple so I only eat the tasty part.

私は赤いりんごが好きじゃないですけど、緑りんごが好き。アメリカではアップルパイの作るのは緑りんごを使います。それでは、緑りんごはとてもおいしいと思う。私もりんごを切ったなければ食べられない。私の歯医者は私のため歯を作ったからりんごを齧られない。切るだけ。
