【答案】Dear fellow students，
Smart phones have become an indispensable part in our life.Lots of students having been adversely affected，we appeal to every one of us to reasonably use smart phones.
It can be noted that dissatisfying behaviors involving smart phones are going viral，such as getting drowned in games and even cheating in exams.As a consequence，it's urgent that we take instant measures.Initially，we call on every student to prioritize our academic work.Fully engaging ourselves in classes rather than phone entertainment，we are more likely to improve our academic performance.What's more，we advocate strengthening the awareness of fair play.A majority of students make persistent efforts to attain higher scores，so all of us are expected to take exams honestly to guarantee fair play.
Irresistible though smart phones are，it's high time that we started from lessening the screen time bit by bit.Let's take action right now!
