求翻译：现在家长、学校强调学习成绩，忽视学生身心健康。学生睡眠不足，时间长了会造成记忆力下降，注意力难以集中等问题。导致上课、自习精力不济等等问题。所以说学生睡眠不足影响学习。学校家长应该加以重视。是什么意思？

Now parents, the school emphasizes academic achievement, ignore the physical and mental health of students. Students ' lack of sleep, will cause memory decline over time, difficult to focus its attention, and so on. Lead to class, study energy poor and so on. So lack of sleep affect the learning of students. Parents should pay attention to the school.
