A：I'm terribly nervous.
我很緊張。
B：Calm down!
冷靜下來!
注釋：
a.nervous為形容詞，表示“緊張的”，由名詞nerve轉(zhuǎn)變而成。
nerve可作“神經(jīng)”解，是可數(shù)名詞;也可表示“勇氣”，此時則為不可數(shù)名詞。
例：He doesn't have the nerve to pursue that girl.
= He doesn't have the guts to pursue that girl.
(他沒有勇氣追那女孩。)
* pursue vt.追求
b.想緩和對方情緒時，可說：
Calm down.
= Cool down./Cool off.
(冷靜下來。)
