第二，核心短语

have a sleep tight

1. 解词释义

Sleep tight源于美国版的“宝贝，晚安。”即：Sleep tight and don’t let the bedbugs bite. （睡得好觉，别让臭虫咬。）在19世纪，美国孩子临睡前最喜欢听父母这样对他们说。其中的tight相当于soundly，well。Sleep tight的意思是“睡得很甜，很香”。

有人认为sleep tight和海军有直接联系，因为军用的海军用的是吊床，只有把吊床的绳子勒紧了，他们才能睡得舒服些。在这里tight的意思就是“stretched or down out fully”，意思是“拉紧的，绷紧的”。

Sleep tight的英文解释为：to sleep warm and safe. It is usually said with good night to someone going to bed. 它可以单独使用，用于口语短句中，也可以如对话中和动词“have”连用做句子的谓语，即：have a sleep tight。

2. 拓展例句

e.g. It was cold in the night and Robert Jordan had a sleep tight.

夜里天气很冷，罗伯特•乔丹睡得香极了。

e.g. She did not even feel wet or cold for she had a sleep tight.

她甚至没有感到潮湿和寒冷，因为她睡得很香。

e.g. I had a sleep tight and awoke, refreshed.

我睡得很香，醒来神志清爽。

e.g. I had a sleep tight last night and I did not hear my mobile phone ring.

今天早晨我睡得正香呢，所以手机响了就没听见了。

第三，咬文嚼字

A sleepless night的意思是“不眠之夜”，sleepless是形容词，意思是“失眠的”。这个短语和动词have a sleep night表示“度过不眠之夜”，也就是表示睡不着觉，整个晚上没能休息的意思。它还可以和动词pass或者spend等连用。例如：

Andrew, who was short-tempered from a sleepless night, was ready to explode.

安德鲁因彻夜难眠而变得暴躁，快要发作了。

She passed a sleepless night in the old house.

她在这间旧房子里度过了一个不眠之夜。

Amidst these thoughts, poor Jones passed a long sleepless night.

可怜的琼斯就这样百感交集，辗转难眠。
