it''s Greek to me 希腊文(天书)
joined at the hip 连体婴(死党，从不分开的两个人)
jump the gun 枪未响先偷跑(抢先)
kick the bucket 踢水桶(翘辫子)
kill two birds with one stone一 箭双雕，一举两得
last straw 最后一根稻草
left a bitter taste in one''s mouth 留下满嘴苦味(留下不愉快的回忆)
light a fire under your butt 在屁股下点一把火(促其行动)
light at the end of the tunnel 隧道末端的光(一线希望)
like shooting fish in a barrel 桶里射鱼(瓮中捉鳖)
