A storm in a Teacup杯水风波；小题大做；大惊小怪
A storm in a Teacup字面意思“茶杯里的风暴”；美国英语为“a tempest in a teapot/barrel”，也作tea-pot tempest.
A storm in a Teacup出自法国著名作家巴尔扎克(Honore de Balzac,1799-1850)记述，这句话出自18世纪法国哲学家和思想家孟德斯鸠的名言。有一次，他听说圣马力诺发生了政治动乱，就用“茶杯里的风暴”来评论。因为圣马力诺是欧洲最小的共和国，只有一万人口，孟德斯鸠认为那里的动乱对整个欧洲局势无足轻重。
探源搠流，远在公元前古希腊了罗马的名人著作中就有过类似的形象比喻。如古罗马著名作家和演说家西塞罗(Cicero)在其著作《论法律》中就有这样的话：excitare fluctus in simpulo,意即to stir up waves in a ladle。此外，还有a storm in a cream-bowl;a storm in a wash-hand basin等说法。尽管它们比喻的形象不同，但都是用来表示much excitement about something trivial;a lot of fuss about a trifle之意。按其比喻意义，相当与“小题大做”大惊小怪。
The people next door are continually quarreling ,but it is usually a storm in a teacup.
What is it all about?Nothing serious,just a tempest in a teapot.
