【英语时差8,16】偏头疼还是脸疼？（上）

If you’ve ever had a migraine headache, you don’t need me to tell you it hurts. Doctors report that about twenty million people suffer from serious headaches, and ten percent of these have intractable pain–meaning it doesn’t go away. But here’s a surprise: the problem isn’t always a migraine. Sometimes very similar symptoms are caused by damage to a nerve¹ of the face, which results in the nerve itself sending nonstop “ouch” signals.

1 nerve   

n.神经；勇气，胆量，沉着，果断

参考例句：

• Did he have the nerve to say that?他竟有脸说这话吗？
• He never got up enough nerve to meet me.他从没有足够的胆量来见我。
