　　常言道“字如其人”。随着电脑的普及率越来越高，老师、家长和学生对书写的重视程度也降低了。据一项调查显示，有85.8%的中学生表示有人说过自己的字迹不好看，对于中学生而言，能写一手美观大方的字还是颇有益处的，而中学生不想改善字迹的理由也有很大差别，如图所示。请写一篇120的英文短文，反映一下中学生不想改善书法的理由以及你是如何看待这个问题的。 注意：字迹 handwriting One possible version： Middle School Students' Attitudes Towards Handwriting

　　Nowadays, with the growing popularity of computers, teachers, students and their parents are paying less and less attention to handwriting.

　　According to a recent survey, about 85.8 percent of the middle school students think that their handwriting is poor. Yet for various reasons, many students don't want to improve their handwriting. 51.5 percent of the students think that they can just use a computer, so there is no need to waste time improving their handwriting, and 32.3 percent believe that they are so busy with the study that they do not have time to practice. 10.9 percent think that practicing handwriting is useless.

　　As the saying goes, “writing style shows the man.” Beautiful and neat handwriting is beneficial, especially for middle school students. Therefore, in my opinion, more emphasis should be placed on this aspect in future. 2016一轮复习：高中选修6Unit5The power of nature课件 ① appoint v.
