The graduating senior published a short article in a periodical, but the theme of his big paper has nothing to do with the published small paper, so it is useless. Now, I'm going to use this published small paper in my big paper (both have similar themes). Is it okay? Besides, my brother has already typed it ... it's best not to use it as a reference. Simply explain the views and data in your brother's essay in your own words. Don't use what you have done to graduate. Yuancx (station contact TA) must not be copied! ! !
