The President of the United States is black, thus, some people think that racism in America no longer exists. Nothing could be further from the truth.

One thing that always helps in writing a summary is not to limit your first draft. People often think they have to keep it short and so have trouble deciding which parts to keep and which to discard. I always told the students I tutored to write down everything, no matter how inconsequential it seemed, and cut it down later. When you have the whole article summarized in long form, you can decide which parts to remove, which sentences can be tightened, and which can be combined. A good summary leaves out unnecessary detail while delivering an overview that covers everything important.
Since it looks as if you are a college junior, you should go to the college library and ask the librarian for help in tracking down a suitable article.

The hard part, of course, will be doing the actual summary, especially if you have no experience in doing such work. Again, my best advice is to seek help at the learning center on your campus. There you will find experienced tutors who will take a genuine interest in helping you. When you are in college, never be reluctant to seek the help that is available, and try as often as possible to get personal help from another human being rather than merely relying on the internet.
