①The health benefits of being out in nature have been well-documented and will seem common sense to many of us, but until now no one has _______exactly how much time might be beneficial. ②The magic number emerged from analysis of a survey of 20,000 people in England, who reported how long they spent in natural environments in the past week, plus their health and well-being.③While individuals who spent less than 2 hours in nature were no more likely to report good health or well-being than those who spent no time there at all, those who spent more than 2 hours had consistently higher health and well-being levels.④“It’s not a huge amount of time. ⑤You can spread it over the course of a week or seem to get it in a single dose, it doesn’t really matter,” says Mathew White at the University of Exeter, UK. ⑥Moreover, the threshold is within reach for most people: the analysis found that the average person spent 94 minutes a week exposed to a natural environment.

①The health benefits of being out in nature have been well-documented and will seem common sense to many of us, but until now no one has quantified exactly how much time might be beneficial. 在大自然中外出对健康的好处已经有充分的证据，对我们许多人来说，这似乎是常识。但直到现在，还没有人确切地量化多长时间可能是有益。

②The magic number emerged from analysis of a survey of 20,000 people in England, who reported how long they spent in natural environments in the past week, plus their health and well-being. 这个神奇的数字是通过对2万名英国人的调查分析得出的。这些人报告了过去一周他们在自然环境中度过的时间，以及他们的健康和幸福感。

③While individuals who spent less than 2 hours in nature were no more likely to report good health or well-being than those who spent no time there at all, those who spent more than 2 hours had consistently higher health and well-being levels. 与根本不呆在大自然中的人相比，呆在大自然中不到两小时的人并不更可能报告自己身体健康或幸福，而呆在大自然中超过两小时的人则始终保持着较高的健康和幸福水平。

④“It’s not a huge amount of time. “时间并不长。

⑤You can spread it over the course of a week or seem to get it in a single dose, it doesn’t really matter,” says Mathew White at the University of Exeter, UK. 你可以把它分散在一周的时间里，也可以一次完成，这都无所谓。”英国埃克塞特大学的Mathew White如此说。

⑥Moreover, the threshold is within reach for most people: the analysis found that the average person spent 94 minutes a week exposed to a natural environment. 此外，这个门槛对大多数人来说都是可以达到的：分析发现，人们平均每周在自然环境中待94分钟。
