阅读下列短文，然后从每小题A.B.C.D四个选项中选出能回答所提问题或完成所给句子的最佳答案。

We have heard about people who have special memories. Recently there has been a report about a woman from Australia who can remember almost every detail (细节) of all the events in her daily life.

    Rebecca Sharrock, 25, is one of just 80 people worldwide who have been identified(确定) as having Highly Superior Autobiographical Memory ( HSAM,超级自传体记忆症). It means she can remember every small event—which most people would forget with in (在......以内) days—as if it had happened just minutes ago.

    "I remember my mum putting me in the driver's seat of a car and taking a picture of me when I was 12 days old,” she said. " That's my earliest memory. I remember every day since then. I can't tell all the dates exactly because I was too young to understand calendars, but I remember what I did that every day, what the weather was like and so on.”

    Rebecca can also re—experience taste. If she's eating something that she doesn't like, she thinks about Black Forest cake, her favorite food, and the memory will be so strong that she can nearly "taste” it.

    However,  sometimes her memories prove (证明) to be painful. Because they're not just events that she remembers. "When I relive （再体验) memories, the feelings return, too,” Rebecca said. "For example, I remember falling over when I was three at my grandparents' house and hurting my left knee. Talking about it now, I feel painful in my left knee. "

    "At night, I have to sleep with the radio/recorder and a soft light on, she added. "1f it's too dark or quiet, my mind would be filled with all these memories and I can't sleep. "
