Imagine one day reading that you had been a subject in a risky science experiment without knowing it. At school, you had been fed cereal laced with radioactive chemicals so scientists could learn more about the digestive system. Because the food was radioactive, scientists could easily trace its path through the body.
Scientists now know that exposure to large amount of radiation can cause cancer, a group of diseases in which bodily cells grow wildly out of control. Some people who were part of the radiation studies later developed cancer and blamed the radiation for causing the cancer. Others are worried the radiation will some day make them sick.
Some doctors say that, in many cases, such fears are unjustified because the radiation doses used in the experiments were too small to cause harm. They also say that since dangers of radiation were less well understood then than they are now, even researchers who used high doses of radiation didn’ t do anything wrong.
Some critics claim that no excuse is acceptable for not informing subjects about the nature of an experiment and giving them a chance to refuse to participate. Today, government rules require such informed agreement whenever a study uses people. [br] The passage is mainly about______.
选项
A、what kind of experiment cannot be done on people
B、whether it is moral to experiment on people without them know
C、how radiation studies are conducted
D、what result can be produced in a radioactive experiment
答案
B
解析
本题为主旨大意题。由文章开头“Imagine reading one day that you had beena subject in a risky science experiment without knowing it.”和结尾“Today,governmentrules require such informed agreement whenever a study uses people.”可以推测本文探讨的是在受试者不知情的情况下对其进行试验是否道德。故选B。
