Terrible life starts again

Several days ago ,my summer holiday ended. I have returned to school, so, once again, I have to get up early, study for a long time every day (except sunday), and have nasty meals. Ahh, the joys of a Chinese high school student's daily life.

Teacher notes:

Using the word 'have' shows that returning was not only one time, but that it continues to affect your life.  The word 'so' is a conjunction, like 'therefore', making what follows into a dependent clause --- too weak to stand alone, needing a connection to the previous independent clause: "I have returned to school".  Moving the many uses of 'again' to an earlier point lets the reader focus on the bad activities as they are mentioned, rather than the repeating of 'again'.  I wrote the change in the last sentence to help you show an ironic ending, rather than ask a question.  If you want it to be a question, it should be after the first sentence, before you begin describing the student's life.  I changed student to singular possessive and added 'a' to identify that it is only you that you are talking about, but the reader will consider this one student (you) to be typical of all students.
