Radioactivity is dangerous. It may cause skin burns; it may destroy good tissues (組織) and it may cause illness that could be passed on to our children and grandchildren, In case of exposure (暴露) it may even cause death.
In the early days of radioactivity, scientists did not realize these dangers, Marie and Pierre Curie, after having worked for a while with radioactive materials, noticed that their fingers were reddened and swollen (紅腫) and the skin was peeling off. Henry Becquered carried a small tube with radium in it in his waistcoat pocket, and was surprised to find a burn on his chest. Other early workers also reported burns and harm of different kinds.
The strange fact that it can harm without causing pain is the warning signal we expect from harmfulness. Pain makes up pull back our hands from a fire or a hot object, but a person carrying radioactive materials had no way of telling whether he is touching something too “hot” for safety. Besides, the “burns” or other harmfulness that radioactivity produces may not appear for weeks. A person may have been hurt without knowing it for some time .

閱讀下面短文,從A、B、C、D四個選項中選出最佳答案。
It was fifteen past nine as Marie hurried into the office building where she was going to work. Her bus had inched along through heavy morning traffic, making her a few minutes late for her very first Job. She decided to start out half an hour earlier the next day.
Once inside the lobby, she had to stand at the elevators and wait several minutes before she could get on one going to the sixth floor. When she finally reached the office marked “Smith Enterprises”, she knocked at the door nervously and waited. There was no reply. She tapped on the door again, but still there was no answer. From inside the next office, she could hear the sound of voices, so she opened the door and went in.
Although she was sure it was the same office she had been in two weeks before when she had the interview with Mr. Smith, it looked quite different now. In fart, it hardly looked like an office at all.
The employees were just standing around chatting and smoking. In the front of the room, somebody must have just told a good joke, she thought, because there was a loud burst of laughter as she came in. For a moment she had thought they were laughing at her.
Then one of the men looked at his watch, clapped his hands and said something to the others. Quickly they all went to their desks and, in a matter of seconds, everyone was hard at work. No one paid any attention to Marie. Finally she went up to the man who was sitting at the desk nearest to the door and explained that this was her first day in the office. Hardly looking up from his work, he told her to have a seat and wait for Mr. Smith, who would arrive at any moment. Then Marie realized that the day's work in the office began just before Mr. Smith arrived.
