Crawl in at a reasonable hour.

在合理的時間睡覺

The National Sleep Foundationrecommends getting seven to nine hours of sleep per night, so what time you hitthe hay certainly matters.

國家睡眠基金會推薦一天睡七到九個小時，所以你什么時候睡覺肯定是很重要的。

If you want to get a good night'srest, try going to bed at a time that's going to optimize your amount of sleep.

如果你想睡個好覺，選擇一個可以優(yōu)化你睡眠的時間上床睡覺。

Ultimately, prioritizing those Zsdoesn't have to be difficult -- and the benefits outweigh the preparation.You'll thank yourself in the morning.

最后，睡個好覺并不困難，而且一夜好眠帶來的利益明顯大于付出的準備。到了早上你會感謝自己的。

【知識點講解】

optimize vt.使完善；使優(yōu)化

例句：

What can you do to optimize your family situation?

你能做什么來使你家庭境況達到最適化?

How to optimize them efficiently is still a question.

如何有效地優(yōu)化仍然還是一個問題。
