受伤也得挑时候 Know When to be Injured

A new study suggests that the timing of a wound affects the speed at which it heals.

一项新的研究表明,受伤的时间会影响伤口愈合的速度。

---

Wounds suffered during the day heal around 60percent faster than those sustained at night.

白天受的伤愈合的速度比晚上的快60%左右。

---

The study showed how the body's circadian rhythm controlled 【 the healing of wounds 】.

伤口的愈合（过程）

这项研究显示了人体的生理节奏是如何控制伤口愈合的。

---

The 【 circadian rhythm 】 is like a clock or timer.

昼夜节律/（生物钟） body clcok

生理节奏就像时钟或计时器。

---

It tells our bodies when to wake up, eat and sleep in a cycle --

它告诉我们的身体在一个周期内什么时候醒来,什么时候吃东西什么时候入睡

---

【① a series of  】activities that repeat themselves 【② day after day 】.

① 一系列的……

② 日复一日（ 强调无变化 ）

Eg: I keep taking care of the injured rabbit day after day so the rabbit is recovering day by day.

这一系列 日复一日重复的活动。

---

Each cycle lasts about 24 hours.

每个周期持续24小时。

---

In the study, researchers found that

在这项研究中,研究人员发现,

---

skin cells moved faster to repair wounds sustained during the day.

皮肤细胞在修复白天的伤口时移动得更快。

---

The researchers examined cells, mice, and burn injury databases.

研究人员检查了细胞、小鼠和烧伤数据库。

---

Specifically, their investigation found the following information:

具体来说,他们的调查发现了以下信息:

---

Nighttime burns - burns suffered between 8 o'clock at night and 8 o'clock the next morning

夜间烧伤一在晚间八点至次日早晨八点的烧伤

---

were 95 percent healed after an average of 28 days.

平均28天以后愈合率到达95%。

---

But after an average of 17 days, daytime burns

但平均17天以后,日间烧伤

---

and 8 at night - were 95 percent healed.

早晨八点至晚间八点地烧伤一的愈合率就会达到95%。

---

In other words, nighttime injuries took an average of 11 days longer to heal.

换句话说,夜间烧伤平均需要比日间烧伤多花11天愈合。

---

The scientists say that circadian clocks 【 play an important part /role】 in healing.

在……起到重要作用/扮演重要角色

科学家们说,生物钟在伤口愈合过程中起着重要的作用。

---

Circadian clocks control many cells in the body

生物钟控制着人体的许多细胞,

---

and affect many biological processes, including

会影响包括睡眠在内的很多生理过程。

---

John O'Neill was a co-leader of the study

约翰奥尼尔是这项研究的联合负责人。

---

"This is the first time that the circadian clock within individual cells

他说,“这是首次证明个体细胞内部的生物钟

---

has been shown to determine how effectively they respond to injuries," he said.

能够决定它们应对损伤的效率。

---
