“open book”竟然不是打开书？这么多年英语课白上了！
趣多多还记得上英语课的时候，
老师可没少对我们说
'Open your book.'或者'Open the book.'
这样说是完全没有问题的
但是如果把'the/your'去了呢？
那意思可截然不同啦！
Open book=翻开书
open book=
① 极坦率的人；一目了然的事物√（形容人）
② 容易理解；显而易见√（形容物）
可以用来形容那些性格真实坦率，没有心机的人。

都写在你脸上了。

closed book＝合上书
closed book=一窍不通√
想一想直译是合上书，书都合上了怎么学习到东西呢，你肯定会对要学习的一窍不通，是不是这样理解就非常好记呀！

想一想读书都把鼻子埋进书里了，那读得可是相当用功了，所以自然而然就可以理解为埋头苦读啦~
