我现在必须得早起去上学，第一，是因为要搭乘公交车；第二，是因为我现在接近青春期了，我必须要加倍照顾好自己。

I had to get up for school earlier than in the past, partly because of having to be bussed to school and partly because I had to take better care of myself now that I was in my preteen years.

我今天必须去上学。我必须努力工作并且服从。

I have to go to school today. I have to work hard and obey.
