Jack won the first prize in yesterday’s English speech competition and he was so excited that he didn’t until late into the night.

A. bring down

B. set down

C. take down

D. settle down

答案：

A. bring down

B. set down

C. take down

(答案→)D. settle down

解析：短语辨析。A使…降低；B写下，记下；C拆卸，记录；D定居，使…安静下来；句意：在昨天的英语演讲比赛中Jack赢得了第一名，他是如此的兴奋以至于知道晚上才安静下来。本句的set down指安静的意思。故D正确。
