问题     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.
The author’ s attitude towards the government decision may be described as______.
选项 A、indifferent
B、favorable
C、critical
D、dubious
答案B
解析 本题为作者态度题。由最后一段可以看出，作者对政府这项规定持肯定态度，四个选项中A、C和D均是消极态度。故选B。
