Passage 2
“Mind over matter” is an English saying meaning that we can control our bodies with our minds. Now scientists are finding more increasing evidence that our mind can have a great effect on our physical health. Since our mind influences how we feel, it's impossible to say that someone is ill just because he feels ill.
The influence of the mind on how we feel is the basis of what is known as the placebo effect. A placebo (which is Latin for “I shall please”) is a harmless, inactive substance. Patients are sometimes given placebo pills and begin to feel better because they believe that they have been given real drugs and expect to respond to them. The placebo effect is very strong: research on pain suggests that up to 30% of the effect of most painkillers is a placebo effect.
So if it's so powerful, why don't doctors use it today?
According to Dr. Persaud, they really do. “All these things like wearing a white coat, going to a hospital, being scanned have a very strong placebo effect,” he says.
The English saying “mind over matter” means that ________.
文章第一段第一句提到“ ‘Mind over matter’ is an English saying meaning that we can control our bodies with our minds.”。由此可 知，“Mind over matter”指的是人们能够通过思想来控制身体。
According to the first paragraph, if you feel ill, ________.
文章第一段最后一句提到“Since our mind influences how we feel, it's impossible to say that someone is ill just because he feels ill.”。由此 可知，由于人们的思想能够影响人们的感觉，所以不能够因为一个人 感觉自己生病了就说他真的病了。故选C。
According to the passage, placebos ________.
文章第二段第三句提到“Patients are sometimes given placebo pills and begin to feel better because they believe that they have been given real drugs and expect to respond to them.”。服用“placebo pills”的病人都会 觉得自己感觉好一点了因为他们认为他们服用了真的药，于是做出反 应。由此可知，“placebo pills”并不是真正的药。故选B。
The placebo effect is based on ________.
文章第二段第一句提到“The influence of the mind on how we feel is the basis of what is known as the placebo effect.”。由此可知，安慰剂 效应的基础是人们能够通过思想来影响感觉。故选D。
From the passage it can be seen that there will be no placebo effect if a patient ________.
从文中可知，安慰剂效应是指表面现象对人产生的治愈效果， 比如穿白大褂的医生让人感觉能救死扶伤、穿白色病服可以病人有安 全感、做理疗可以让病人放心等。而吃糖丸是不会产生安慰剂效应的。故选C。
