Task 2 Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45. Charles R. Drew was a medical student at Columbia University in New York. Before he graduated, he wrote an article on blood bank—that is, the storing of blood. Up till then, a lot of people had died from lose of blood because there was no such thing as a blood bank. When the United States entered the Second World War, it became necessary to set up blood banks. Dr. Drew served as the head of the Red Cross's first blood bank. When the Red Cross started blood banks to collect and store blood for men wounded in the battle, black Americans gave blood along with the whites. At first their blood was not accepted. Later, blood from blacks was accepted but stored in a different place from “white” blood. Although the head doctors insisted that there was no difference at all between the blood of blacks and whites, the Red Cross, with the support of the government, continued to separate black blood from white. After the war Dr. Drew was driving with three other doctors to attend a meeting in a southern state. In North Carolina their car went into a ditch(水沟)and Dr. Drew was badly hurt. He had lost a lot of blood by the time a passing ear took him to the nearest hospital. “We don't take in blacks. ”They said. He had to be taken to the colored hospital. On the way Dr. Drew died because he had lost too much blood. What does the phrase “blood bank”(Line 2, Para. 1)mean?
