Kim's brain is not great at seeing emotion. When she looks out at the world she physically sees all the things that most people see, but with much of the emotion _1.（除去）_. She sees the same tables, the planes, the trees ... the people moving back and forth. But the feelings — particularly the _2.（微妙的）_ones — are invisible. Though for most of her life she didn't realize that.
"This is the interesting thing," Kim says. "We believe our senses, so I didn't know I was missing anything. If I'm seeing people talking and it simply looks like people are talking, why should I think that they might be feeling angry or sad or anything, if I'm not sensing that?"
This is the story of how Kim was given a window into the world she couldn't see and how that changed her frame of reference. It was a small window — it only lasted 90 minutes. But it turns out that 90 minutes is more than enough time to _3.（动摇）_a life. Because all you need to do to _3.（动摇） _ a life is expose it to a new frame of reference.
