你总是不敢参加冒险活动吗?可能是某个基因在作祟。


YOUR friends are talking about how exciting the roller coaster (过山车) is. You can't say a word because you feel afraid and cannot ride it. Why do some people take risks (冒险)? Why don't you?

American scientists might be able to answer the question. They found a gene (基因) called nueroD2. It may have to do with a part of the brain (大脑) called the amygdala (杏仁核). Nerve cells (神经细胞) in the amygdala make people feel fear.

If people have only one copy of nueroD2, they have fewer nerve cells in their amygdala. Their brains would not feel as much fear.

People with two copies of the gene have more nerve cells in their amygdale. So their brains would feel more fear.

When you feel fear, you stay away from risky things.

So if your friends ask why you don't ride the roller coaster, tell them it's because of your nueroD2.
