In my opinion, it’s necessary for us to control the using time.For example, we can set a 1-hour limit per day for non-study use.All in all, smartphones are good tools if we use them properly. 【范文二】Smartphones: good or bad for students? A survey about 1400 eighth graders’ smartphone use came out recently.55% of the students use phones for study, like looking up new words and attending online English classes.While the rest use them for fun, such as playing games or watching short videos. On one hand, smartphones can improve our learning efficiency.Besides, they can enrich our after-school life.On the other hand, spending too much time on phones may distract us from study.It can even cause sleep problems. I suggest that we should make a daily usage plan.For instance, we can put away phones during homework time.It’s important to balance study and phone use. 【范文三】How to use smartphones wisely We did a survey on 1400 eighth graders’ smartphone use and got some interesting results.55% of students use phones to do online research and practice English listening.Only 45% of them use phones for entertainment in their free time. On one hand, smartphones help us broaden our horizons by letting us get global news quickly.What’s more, they save communication costs when we chat with relatives.On the other hand, over-reliance on phones will reduce face-to-face communication and affect our schoolwork. All in all, we should use smartphones in a right way.Take ourselves as an example, we can set screen-time reminders and choose more educational content instead of playing games all the time. 0 1 学科网（北京）股份有限公司 $
