以下内容精简自每日英语听力2.12内容“What is consciousness? - Michael S. A. Graziano”
原文大意：一个中风的病人分不清存在明显差异的两个图像，却能从感觉上告诉别人自己更喜欢哪一个。分不清差异是因为她大脑的model不起作用了，而感觉上的差异是通过她的consciousness来感知的。（即自己能看见，但自己不知道自己能看见。也就是“视而不见”。）

Here are two images of a house.
There's one obvious difference, but to this patient, P. S. , they looked completely identical.
P. S. had suffered a stroke that damaged the right side of her brain, leaving her unaware of everything on her left side.

But though she could discern no difference between the houses, when researchers asked her which she would prefer to live in, she chose the house that wasn't burning— not once, but again and again.
The brain builds models, which are continuously updating, simplified descriptions of objects and events in the world.
These models never capture every detail of the things they describe, just enough for the brain to determine appropriate responses.
1.找主干
加粗部分即句子主干
2.逐句看
Here are two images of a house.
主干是：这里有两个图像。
两个什么图像呢？a house的两个图像。
There's one obvious difference, but to this patient, P. S. , they looked completely identical.
主干是：（两个图像）有一个差异，但看起来相同。
差异明显吗？
明显（obvious）
为啥差异明显却看起来相同？
因为是对P. S.这个病人而言（to this patient, P. S.）
P. S. had suffered a stroke that damaged the right side of her brain, leaving her unaware of everything on her left side.
主干是：P. S. 中风过。
什么样的中风？
damaged the right side of her brain（损害其右脑的中风）
中风的后果呢？
leaving her unaware of everything on her left side.（察觉不到她左边的一切）
But though she could discern no difference between the houses, when researchers asked her which she would prefer to live in, she chose the house that wasn't burning—not once, but again and again.
主干是：她选择了房子。
？
情景是这样的：
when researchers asked her which she would prefer to live in（研究人员问她想住哪一间）
选择了什么样的房子呢？
that wasn't burning.（没有着火的房子）
这样的选择是偶然的吗？
not once, but again and again.（不是偶然的）
discern：（仔细思考之后）觉察出，弄清楚，辨明
The brain builds models, which are continuously updating, simplified descriptions of objects and events in the world.
这句话的主干是：大脑建立模型。
什么模型？
1.continuously updating（是不断更新的模型）
2.simplified descriptions of objects and events in the world. （是事物的简化描述）
These models never capture every detail of the things they describe, just enough for the brain to determineappropriate responses.
主干是：这些模型不能反映细节。
什么细节？
1.every（所有细节）
2.the things they describe（模型所描述的事物的细节）
不能反映所有细节，那能在多大程度上反映呢？
just enough for the brain to determine appropriate responses.（够大脑作出合适反应用就行）。
盲视（blindsight）：意识性的视觉丧失，而还是能够对投射到盲区的刺激进行准确的判断和辨认。这种现象被称为盲视。
model：模型、概念等，是事物的简化，目的是提高认知的效率
consciousness：感觉、直觉等，是事物原貌的综合反映
例如，向别人介绍央视大楼的形状时，consciousness会给出以下图片
real world
而model会给出“大裤衩”三个字。
