Question

Imagine reading one day 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 amounts 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 blame 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 the 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.

1. The passage is mainly about ______ .
A) whether it is moral to experiment on people without their knowing it
A) what kinds of experiment cannot be done on people
B) how radiation studies are conducted in a secret way
D) what result can be produced in a radioactive experiment
2. The word "laced" in paragraph 1 most probably means ______ .
A) surrounded B) mixed C) covered D) confused
3. Which of the following is true according to the passage?
A) Radioactive chemicals were once used to cure diseases with the digestive system.
B) When the danger of radiation had not been proved, high doses of radiation were acceptable.
C) Most cancers are caused by radiation.
D) Radioactive chemicals can cause bodily cells to grow wildly out of control.
4. Today, government rules ______ .
A) prohibit all tests related to human beings
B) disapprove of experiments with uncertain results
C) demand to protect people's right to refuse to be tested
D) demand to stop all experiments harmful to people
5. The author's attitude towards the government's decision may be described as
A) favorable B) critical C) dubious D) indifferent

想象一下，阅读有一天，你在有风险的科学实验，而不知道它的主题。在学校里，你已经够了谷物股价放射性化学品，所以，科学家可以了解更多的消化系统。由于食品是放射性，科学家可以很容易在体内的追踪它的路径。
科学家现在知道，接触大量的辐射可能导致癌症的疾病，其中身体细胞生长得失去了控制组。有些人谁都是后来患上癌症的辐射研究的一部分，并指责导致癌症的辐射。其他人担心的辐射有一天让他们生病。
一些医生说，在许多情况下，这种担忧是没有道理的，因为辐射实验中使用的剂量太小，造成伤害。他们还表示，由于辐射的危险是不充分理解当时比现在，研究人员甚至谁用高剂量的辐射并没有做任何错事。
