A new study suggests that the timing of a wound affects the speed at which it heals(痊愈). Wounds suffered during the day heal around 60 percent faster than those at night.
The study showed how the bodies circadian rhythm(昼夜节律) controlled the healing of wounds. 1 It tells our bodies when to wake up, eat and sleep in a cycle—a series of activities that repeat themselves day after day. 2
In the study, researchers found that skin cells moved faster to repair wounds suffered during the day. Their findings were published in the Journal Science Translational Medicine.
The researchers examined cells, mice, and burn injury databases. 3
Nighttime burns—burns suffered between 8 o’clock at night and 8 o’clock the next morning were 95 percent healed after an average of 28 days.
But after an average of 17 days, daytime burns -burns suffered between 8 o’clock in the morning and 8 at night were 95 percent healed. 4
Wounds are very costly to treat. 5 In Britain’s National Health Services, for example, such services cost around $6. 56 billion per year. Experts say the high costs result, in part, from a lack of drugs that speed up the closure of wounds.
A. Each cycle lasts about 24 hours.
B. The circadian rhythm is like a clock or timer.
C. Specifically, their investigation found the following information:
D. The new study’s findings could help scientists develop drugs better.
E. In other words, nighttime injuries took an average of 11 days longer to heal 95 percent.
F. Worldwide, billions of dollars are spent every year on wound-treatment services.
G. That’s what a group of researchers from a university in Canada recently published.
【文章大意】本文介绍了一项科学研究, 研究表明在白天受的伤比在夜晚受的伤愈合得更快。
1. 【解析】选B。根据空后信息可知, 此处作者强调昼夜节律有很强的周期性, B项衔接前句, 表明昼夜节律像时钟或者计时器一样, 符合语境。
2. 【解析】选A。根据空前句中的 “a cycle—a series of activities that repeat themsevles day after day”可知此周期每天循环, 由此可判断周期时长为24小时, 故选A。
3. 【解析】选C。空前提到研究人员研究分析了烧伤数据库, 空后谈到调查研究结果, 由此判断C项符合语境。
4. 【解析】选E。由上文信息可知, 夜晚受的烧伤修复95%需要28天的周期, 而白天受的烧伤修复95%只需要17天。因此可以判断, 夜晚修复95%的平均周期比白天长11天, 故E项符合语境。
5. 【解析】选F。根据空前句可知, 创伤治疗费用高, 后文举例“such services cost around $6. 56 billion”说明治疗费用很高, 因此F项符合语境。
