　　The Negro has a callus growing on his soul and it is getting harder and harder to hurt him here. That is a simple law of nature. Like a callus on the foot in a shoe that is too tight. The foot is nature’s and that shoe was put on by man. The tight shoe will pinch your foot and make you holler and scream. But sooner or later, if you do not take the shoe off, a callus will form on the foot and begin to wear out the shoe.

　　It is the same with the Negro in America. That shoe-the white man’s system—has pinched and rubbed and squeezed his soul until it has almost destroyed him. But it did not. And how a callus has formed on his soul, and unless that system is adjusted to fit him, too, that callus is going to wear our that system.

　　5. 拟人

　　Dawn was beginning to prowl about the sky and put out the starts.

　　6. 夸张
