Questions 32 to 35 are based on the following passage.

When you take a pill, you and your doctor hope it will work —and that helps it work. That’snot a new idea. But now researchers say they know just how much of a drug’s effect comes fromthe patient’s expectation: at least half.

When patients in the midst of a headache attack took a dummy ( 假的) pill which they thoughtof as a widely used headache drug, it reduced their pain. It worked almost as much as when theytook the real drug thinking it was a placebo (安慰剂).

“There was no difference between the real drug and the placebo dressed up with a nice word inreducing pain,”researcher Ted Kaptchuk says. “Basically we show that words can actuallydouble the effect of a drug. That’s pretty impressive.”

And if it works when treating headaches, it also might work for a wide variety of otherillnesses. The findings have interesting implications for doctors and patients, because what doctorssay about a medicine appears to have a lot to do with its benefits.
A.half of the drug’s effect, if not more, is from the patients’expectations
