V. Answer the questions.
"Mrs Biden, your son is in trouble," Mr Walls said on the phone.
"What was wrong with him?" a woman asked worriedly.
"He was reading a novel on the mobile phone in class," Mr Walls added.
That boy was me, Joe Biden, 14 years ago. Then I had the terrible habit of reading novels in class on the phone and sometimes got caught by my teacher.
The situation has been a bit different in recent years. Almost every kid owns a smart phone. They can read novels, play games, pass notes and watch TikTok videos on it.
Nowadays, the improper use of smart phones is a serious and common distraction schools are facing. Some schools are trying to limit the use of smart phones on campus. A school in Los Angeles requires that students should put their phones in a locker until the end of the school day.
Although schools have taken action to reduce the bad effect of the smart phone, some children are clever enough to find ways out. For example, some bring two phones to school—one is handed in to the teacher while the other is kept secretly.
Students must realize that their regular use of smart phones at school has a negative effect on their learning and even on their physical and mental health.

4. It has a negative effect on their learning and even on their physical and mental health.
5. Students should not use smart phones during class time. / Schools can set up special areas for students to use smart phones after class.
解析：1. 根據(jù)“That boy was me, Joe Biden, 14 years ago.”可知電話交談發(fā)生在14年前。
2. 前文提到“Almost every kid owns a smart phone.”，此處“on it”指在智能手機(jī)上，it指代the smart phone。
3. 根據(jù)“A school in Los Angeles requires that students should put their phones in a locker until the end of the school day.”可知答案。
4. 根據(jù)“Students must realize that their regular use of smart phones at school has a negative effect on their learning and even on their physical and mental health.”可知答案。
5. 建議合理即可，如“學(xué)生不應(yīng)在課堂上使用智能手機(jī)”或“學(xué)校可設(shè)置專(zhuān)門(mén)區(qū)域供學(xué)生課后使用智能手機(jī)”。
