未来形と未来完了形の違い

I will visit you at 3 pm tomorrow.

未来完了形のイメージ

未来完了形パターン１

I will have lived here for 7 years by next month.

未来完了形パターン２

If I watch this movie one more time, I will have watched it 10 times.
※ I will watch it 10 times.と言うと「これから１０回観る」という意味になってしまう。

未来完了形パターン３

I will have finished my homework by the time you come home.
