容忍

how can you put up with all these difficulties?

适得其反

your scheme backfired on you.

这句话的意思就是“聪明反被聪明误”，scheme做小诡计解。

熟视无睹

the teacher turned a blind eye to jerry’s cheating in the exam.

水泄不通

the bus was packed/crowded in like sardines.

sardine本身就是沙丁鱼，但是它一般被做成罐头，人们特别爱吃。于是，沙丁鱼罐头就被借做比喻很拥挤的情形。carlton最喜欢的歌手陶喆david tao曾有首歌叫《我喜欢》，有一句就唱到：“挤在公车上像个沙丁鱼，每天上班下班是规律”

说曹操曹操到

speak/talk of the devil! we were just talking about you, tom.

这个典故很有意思，古时候人们以为提及恶魔，恶魔就会来到身边。莫非曹操也是“恶魔”？其实不尽然，曹操也非“枭雄”。

瞎蒙

i had no clue how to solve the math problem then, thus i took a shot in the dark and made my choice.

该习语相当形象，往黑天乱打枪就是瞎蒙。

知根知底

i’ve known john since he was 4. i can read him like a book.

还是那句话，读人如读书。
