Hi Helen，I don’t think you’re right. Students should pay attention to their study. Mobile phones are not always necessary. They’re not like books and pens. You should understand your parents and do what they ask you to.
As the old saying goes，where there's a will， there's a way.亲爱的老师们、同学们:这套练习分默写版和完整版，完整版是供孩子们背记的，默写版是供孩子们进行默写自我检测或者老师们用来检查学生们的掌握程度。
