英语问题。英语阅读理解。

"Mind over matter" is an English saying meaning that we can control our bodies with our minds.Now scientists are finding increasing evidence that our mind can have a great effect on our physical health.Since our mind influences how we feel ,it's not possible to say if someone is ill just because they feel ill.
The influence of the mind on how well 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 is 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,and being scanned have a very strong placebo effect,"he says.

From the passage it can be seen that there will be no placebo effect if a patient_____.
A.is dressed in white
B.has a physical exam
C.takes sugar pills
D.sees a doctor
这道题给的答案是A,为什么选A?根据什么推导出来的？

Answer 1

这篇文章讲的就是人类的意识有的时候可以控制自己的身体健康。

这里作者大概举了一个例子就是有一种方法叫做placebo，意思是安慰剂。在有的时候，病人服用一些安慰用的药片（这里可以推出C正确）可以感觉病变好了，原因是他们觉得服用了真正的药物。

最后一段，大家知道，病人在意识上市很虚弱的，他们渴望得到治疗，于是如果你作为医生身穿白大褂，或者带病人去医院做检查等都能起到很好的安慰作用。（推出B和D正确）。注意，这里指的是病人以外的人，而不是病人本身。所以A错误。

Answer 2

1、短文第一、二句话的意思的是：它蔑视
绝大多数人毕生所追求的（A选项）。他也不想要（B选项）。第一个疑问来自于：such
simple
things
as
his
work
and
playing
the
violin
and
sailing
his
boat.
关键词在于：such
A
as
B.这个结构
中，A包含B，B只不过是A的一个例子。
2、第二个疑问来自于：but
contempt
for
the
things
most
people
set
their
hearts
on-for
fame
and
money
中most
people
set
their
hearts
on是省略了that的定语从句，修饰the
things."-for
"当中特别要注意的就是“-”看这个结构你就容易明白了contempt
for
。。。。—for
fame
and
money
“-for
”可以理解成such
as.

Answer 3

很明显从最后一句可以看出来，最后一句中wearing a white coat 是指医生穿白大褂，而答案A的意思是病人穿白大褂，病人穿白大褂怎么能起到安慰剂的效果呢？而其它的答案B做检查 C吃糖做成的药 D看医生 均可起到安慰剂的效果。明白了吗？

Answer 4

我觉得关键在patient这里 穿白色衣服等等这些 仅仅是对正常人来说 有一定的安慰效应 或者说是没有病的人来说 而对于病人就没什么效果了 而且这个用排除法也应该选A

Answer 5

我觉得选C吧
选A的话,好像课文中All these things like wearing a white coat是说医生穿着白色的衣服吧.
