混合类大作文，教育类话题
Some children spend hours every day on their smartphones. Why is this the case? Do you think this is a positive or a negative development?
题目来源：剑17Test2大作文
题目大意
有些孩子每天花几个小时在智能手机，原因是什么？你认为这是一个积极的还是消极的发展？
思路解析
这是一道报告类大作文，聊的是儿童使用智能手机的问题。报告类的题目结构比较简单，两个主体段分别对应两个问题，主体段一讨论原因，主体段二讨论利弊。文章理解上不难，审题时注意讨论的限定对象“children”和“smartphones”，不要歪了，比如有学生可能讨论到TV等等。下面月半鸭和大家一起来看下具体观点。
首先来看“孩子花几个小时在手机上”的原因，主要有两方面。
一是智能手机在当今社会非常普遍，这一代孩子们从出生开始就能接触到。作为数字原住民，这些孩子在成长过程中已经习惯于用手机学习、玩游戏甚至与他人交流，因此他们在手机上需要花费许多时间来完成这些事项。
二是孩子的父母可能忙于工作没有时间陪伴孩子，因此会让孩子去用手机玩游戏或看动画片进而避免打扰自己。而这些游戏往往容易让人上瘾，如果孩子缺少家长的监督，可能会花大量的时间沉迷其中。
然后来看利弊讨论。
好处在于，孩子能更熟练掌握如何使用手机并且这会让他们未来生活更加便利。在现代社会，手机确实已经成为一个非常重要的生活工具，无论是获取信息、与人交流还是完成各项事务都需要使用手机，因此对手机熟练运用是必不可少的。
坏处则有两个。一是长时间使用手机会对孩子的身体健康造成负面影响。孩子尚且处在身体发育的过程中，一直盯着手机屏幕会造成孩子视力下降，而长时间坐着玩手机不运动也容易引发儿童肥胖等健康问题。二是孩子花大量时间沉迷手机会导致他们花在学习、交友及身边事物的时间变少，并且难以集中精力完成学业，这对于他们的升学和未来成长都是非常不利的。
提纲
高分范文示例
In modern society, it is not surprising to see children using smartphones for hours a day. For better or worse, this trend has already begun to affect them in certain aspects of life.
The causes of this trend are manifold. One possible assumption is that the absence of parental company leads to children’s excessive use of smartphones. This is because parents who are occupied with heavy workloads are likely to leave their kids with video games or cartoon series on their smartphones to kill time. As a result, attracted by such addictive forms of entertainment, these immature minds who lack self-discipline and parents’ guardianship tend to become addicted to the virtual world. Another reason might be that today’s younger generation grow up with digital devices, and these digital-natives get used to the routine in which smartphones are utilized to socialize with friends, get access to updated information, or complete assignments . These activities undoubtedly prolong the time they spend on smartphones.
Though the use of smartphones is conducive to developing children’s digital literacy and preparing them to be technologically savvy, I believe that it is detrimental to their overall development. For one thing, the excessive exposure to digital devices would disrupt children’s physical health. The prolonged screen time, together with a sedentary lifestyle, not only damages their eyesight, but also increases the risk of developing chronic conditions such as obesity, diabetes and hypertension. For another, once kids are drawn to smart devices, they will find it hard to focus on other things around them and will be unable to concentrate on schoolwork or family life. In the long term, this unhealthy lifestyle will pose a threat to their academic performance and family relationships.
Overall, this trend might stem from a variety of causes, and it should be a negative one as it is harmful to children both physically and mentally.
