阅读：W hat is the importance of the AfroAmerican history to all Americans Questions 36 to 40 are based on the following passage: W hat is the importance of the AfroAmerican history to all Americans? How could AfroAmericans contribute anything to American history when they were just slaves and servants? This is the image which many of us are taught when　we go to school. This is the image many AfroAmericans have of themselves also. The AfroAmericans need to remake their real historical image so that it is　known and accepted in its truthfulness by themselves and the rest of the world. Men and women of darker color are human beings entitled to respect and acceptance in history.　When we think of famous scientists and inventors we immediately think of men such as Alexander Graham Bell, Thomas Edison and Jonas E.Salk. This is because we associate famous people with the AngloSaxon race. But what　about the AfroAmerican inventors and scientists? How many men during World War Ⅰ owe their lives to Garrett Morgan who invented the gas mask? Garrett Morgan also invented the traffic light which saves numerous lives on our streets. Daniel Hale Williams was the first successful heart surgeon. Charles Drew saved hundreds of thousands of lives during World War II by his discovery　of the ways and means of preserving blood plasma. Percy Julian has helped millions suffering from the excruciating pain of arthritis. These men and others should be as easily recognized as Bell, Edison and Salk.  America is made up of many different blends of cultures. These many cultures have come to enrich and diversify the American way of life. We should　not think, because history has neglected to include the background of a particular culture, that these people have an inferior history. We should search for the truth and set the record straight against the slanders, the stereotyping and false images which have identified these people. We should understand each of the cultures and learn of their specific contribution to America's life　story. Only after we are taught the complete and accurate history of our great country and learn that the blending of cultures and backgrounds gives us ourstrength, can we go forward on the path to peace. 36.
