D.Placebo.
答案:C 细节理解题。A、B、D三项中的物品是用来做实验的物品。在文章第四段最后一句“The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.”可知Capsaicin(辣椒素)用来引起咳嗽和作为这些药物如何止咳的依据。
3.We learn from the text that volunteers in the experiment ________.
A.were patients with bad coughs
B.were divided into the three groups
C.received standard treatments
D.suffered little side effects
答案:B 推理判断题。从第四段首句“Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment.”可知实验中每组人吃一种所给的物品才能看出止咳的效果,故需要三组志愿者。
4.Which of the following would be the best title for the text?
A.Codeine: A New Medicine
B.Chocolate May Cure Coughs
C.Cough Treatment: A Hard Case
