YESTERDAY

I couldn't attend this class because of biology experiment.

I asked a teacher whether I could carry out to this English lesson.

The answer was that "NO"

Since I don't want to be absent,I was disappointed at the sentence.

The experiment was finished past 18:00.

And more,the teacher said us that"The experiment of next week may be finished at 20:00."

I think I will not be able to attend next week,I will write this blog hard.
