I am primary school now, this is my second year, in order to focus more on my study, I live in school now, I will go home on the weekend. Our school is under construction lately, the workers are doing their work in the daytime, the machines make out large noise, I can’t focus my mind on the study. That’s not the worse situation, when I take a nap in the afternoon, the machines are still working, I can’t sleep. So when I wake up, my head is not well working, I want to sleep all the day. The school should limit the time for the workers, they should stop working during the snap time for school. It will be reasonable for students.
