三、英文短文寫作。(45 分)
American civil rights activist, W. (E) B. Du Bois, once said, “The problem of the twentieth century is the problem of the color line: the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea.” The “color line” here refers to the racial segregation that existed in the United States after the abolition of slavery. In your opinion, what is it that segregates people in the world in the 21st century? How does it divide, discriminate and alienate people? Is it possible to spot a silver lining in this segregation? If so, what can be done? Express your ideas by using a real case and write an essay of no more than 350 words with an introductory paragraph, a main body containing 3 to 5 major points and a conclusion.
