问题    On May 12, 1946, Louis Alexander Slotin was carrying out an experiment in the laboratories at Los Alamos with seven other men. Slotin was good with his hands; he liked using his head; he was bright and a little daring-- in short, he was like any other man who is happy in his work. At Los Alamos, Slotin, then aged thirty-five, was concerned with the assembly of pieces of plutonium, each of which alone is too small to be dangerous and which will only sustain a chain reaction when they are put together. Atomic bombs are, in fact, detonated in this way, by suddenly bringing together several harmless pieces of plutonium so that they form a larger, explosive mass. Slotin himself had tested the assembly of the first experimental bomb which had been exploded in New Mexico in July, 1945.
   Now, nearly a year later, Slotin was again doing an experiment of this kind. He was nudging several pieces of plutonium toward one another, by tiny movements, in order to ensure that their total mass .would be large enough to make a chain reaction; and he was doing it, as experts are tempted to do such things, with a screwdriver. The screwdriver slipped, the pieces of plutonium came a fraction too close together and suddenly the instruments everyone was watching registered a great upsurge of neutrons, which is the sign that a chain reaction had begun. The assembly was filling the room with radioactivity.
   Slotin moved at once; he pulled the pieces of plutonium apart with his bare hands. This was virtually an act of suicide for it exposed him to the largest dose of radioactivity. Then he calmly asked his seven co-workers to mark their precise positions at the time of the accident in order that the degree of exposure to the radioactivity each one received could be fixed.
   Having clone this and alerted the medical service, Slotin apologized to his companions, and predicted what turned out to be exactly true: that he thought that he would die and that they would recover.  Slotin had saved the lives of the seven men working with him by cutting to a minimum the time during which the assembly of plutonium was giving out neutrons and radioactive rays. He himself died of radiation sickness nine days later.
   The setting for his act, the people involved, and the disaster are scientific, but this is not the reason why I tell Slotin’s story. I tell it to show that morality shall we call it heroism in this case? has the same anatomy the world over. There are two things that make up morality. One is the sense that other people matter: the sense of common loyalty, of charity and tenderness, the sense of human love. The other is a clear judgment of what is at stake: a cold knowledge, without a trace of deception, of precisely what will happen to oneself and to others if one plays either the hero or the coward.  This is the highest morality: to combine human love with an unflinching, scientific judgment.
   I tell the story of Louis Slotin for another reason also. He was an atomic physicist who made a different choice from mine. He was still working on bombs when he died, a year after World War II ended. The essence of morality is not that we should all act alike but that each of us should deeply search his own conscience--and should then act steadfastly as it tells him to do.
What is the main point of the passage?
选项 A、To warn people of the dangers of atomic power.
B、To describe the heroism of Louis Slotin.
C、To make a statement about what morality means.
D、To express the author’s view of a scientist’s duty.
答案C
解析 文章先用大量篇幅(前四段)讲述了一个科学家做实验的故事，到第五段才点出讲故事的用意，即用以说明何谓道德，并分析了道德的两个组成部分：对他人有爱心，对形势能作出清醒而科学的判断。因此文章重在讨论道德问题，正确答案为C。
