How to buy strawberries...
怎么买草莓……
Smell them. If they smell like strawberries buy them, they will taste divine. If they look gorgeous but have no smell, they will have no taste.
闻闻看。如果闻着像草莓，那就买吧，这吃起来是极好的。如果看着挺不错可是闻起来没什么味道，那吃起来也不怎么样。
Simple and foolproof. If people give you a strange look because you\'re smelling the strawberries, let them not smell and buy the tasteless ones.
这种方法既简单又可靠。如果别人觉得你闻草莓的行为很奇怪，那就让他们不去闻，然后去买那些不怎么样的草莓吧。

Try to stay awake: Challenge yourself to stay awake – your mind will rebel! It\'s called the sleep paradox.
试着保持清醒：挑战自我，让自己保持清醒——这样你的大脑就会抗议！这就叫睡眠悖论。

Keep your eyes wide open, repeat to yourself \'I will not sleep\'. The brain doesn\'t process negatives well, so interprets this as an instruction to sleep and eye muscles tire quickly as sleep creeps up.
一直睁着眼睛，不停地告诉自己“我不睡觉”。因为大脑无法很好地处理否定信息，所以这种指令也被解释为睡觉，而且眼肌也会疲劳，这样睡意很快就来了。
