As usual,they'll be thick as thieves.
所以,一如既往地,他们还会变得非常亲密。
Thick-as-thieves,是习惯用语。我们都知道: Thieves就是偷东西的盗贼,thieves是复数,它的单数是:thief。尽管thick-as-thieves里有thieves,但是它的意思和偷东西毫无关系。Thick-as-thieves的意思:和某人在许多问题上都采取同样立场,互相支持,或者说和某人的关系十分密切。请看例句:
For centuries,Klaus and Marcel had been as thick as thieves,though the war of French quarter teared their friendship apart.
一个世纪以来,Klaus和Marcel都是亲密无间,但是争夺法属地区的战争让他们昔日的情谊荡然无存。
