He told me I 5 Siept through the whole summer. but that luckily I woke up just in time for the first day of school. 1ou might think I was pretty dumb for falling for that one, but Rodrick was dressed up in his school clothes and ohe'd set my alarm clock ahead to make it look like it was the morning.

After Rodrick woke me up, I iust got dressed and went downstairs to make some breakfast, like I do 10 every morning on a school day.

この問題がわかりません。 全体を分かりやすく説明してくださると嬉しいです。 また、特に線を引いた部分がよくわかりません どうしてこの式が出てきたのでしょうか?? よろしくお願いします🙇‍♀️💦💦
