thrown in at the deep end被陷入困境
get into hot water遇到麻烦；惹来麻烦
put my foot in it无意当中说出来了尴尬的话
get on like a house on fire和某人合得来，一见如故
a fish out of watet与环境格格不入；不得其所
a real eye opener令人大开眼界，感到吃惊
going places大有作为；事业顺利；春风得意
a level playing field公平竞争环境
in the driving seat掌管，控制地位
to be neck and neck齐头并进；实力不分上下
flogging a dead horse自费口舌；做无用功
move the goalposts（消极）双重标准；改变目标/规则
keep your eye on the ball全神贯注
a one-horse race胜负分明的比赛；结果清晰
