同学,很高兴回答你的问题
正确答案如下：
我只把需要修改的部分改过来,你参考一下
As we know,mobile phones can be coinvent and comfortable.（把offer改成be )
最好把句中的每一个child都改成children,因为这是对所有的孩子来说的.
另外第二段第三行中的have是原形,而主语是child是第三人称单数,这也是错误
同样,Besides,a smart phone have a great number of applications such as electronic dictionary,也应该把have改成has
Students also can use these application to improve their learning efficiency.把application改成applications,复数形式
总之,这篇作文整体上写的很好,写出了对学生带手机的看法,很有自己的独到见解,只是有一些小的语法错误而已

Nowadays, cell phones 【becomes去掉s】 more and more popular 【for 改为with 因为be popular with sb】 students. As we know, mobile phones can 【offer改为be】 coinvent and comfortable; however, there are also some disadvantages, such as distracting study and affecting health. Hence, as for me, instructors should ban moble phones in their classrooms.
Some parents think that their child should be allowed to use cell phones, for mobile phones are not entirely harmful. To begin with, parents can easily keep in touch with their child by cell phones. Meanwhile, if 【child children】 have some emergency situations, they also can tell their family 【quickly改为as far as possible】. Besides, a smart phone have a great number of applications such as electronic dictionary, electronic book and surfing internet. Students also can use these 【application加s】 to improve their learning efficiency.
