A data shows more than half of 4,500 high school students pl

抄袭并不论你抄了百分之多少,甚至只抄了几句话,都无法改变这个学生抄袭的事实,除非你用引用符号或者是标记出原作者
再问： 可以帮我找出一些语法错误吗？谢谢
再答： Data (data不能用a来做冠词，你也可以用Some不过不精确) shows that more than half of 4,500 high school students admit to plagiarising from internet。 (plagiarism是名词，你可以直接用动词形式在students后面直接用plagiarise或者用admit更正式一点) Defining plagiarism is irrelevant to counting how many words or how large proportion are copied from other articles。 （之前这里你这是把词语堆起来，并没有把他连贯成合理的句型）Copying even few words will not change the fact that plagiarism has been done （不要随便用and，英文很强调逻辑性，有并列关系采用and，要不就重新起一句，最后你愿意用student也可以说the fact that the student has done plagiarism）unless quotation marks or references are used in correct ways。（一般都说reference而不是note the author，还有只是常识性的必须要以正确的方式运用reference才不算plagiarism）
