帮我检查一篇英语作文，越详细越好，谢谢！

how often是问频率的，可你下文的内容跟hhow often有什么关系？
一班的刘明，顾名思义是刘明属于一班的，但你的class one of Liu Ming变成了一班是属于刘明的
information是属于Liu Ming 的还是Class One的？下文的he应该是Liu Ming的吧
一班刘明的信息，我觉得这句话分成两部分翻译较好
visits websites on the Internet比较好，个人觉得computer不好
download没有加s
最后一句有点重复，个人觉得去掉比较好(更何况是个病句)

第一句:tell you something about how often the students do things on computer.第二句:this is the information of Liu Ming who is in Class one.第三句还行，第四句:he often surfs on the Internet by it.第五句把play后的 computer去掉，显得啰嗦了，第六句on the变成by，第七句downloads,第八句和前面一样

He always uses the computer to do his homework, and surfs the Internet. However, he never uses the computer to play games. Definately, he is a good student.
