Unit 3 The Million Pound Bank Note

李仕才

【阅读理解插花】

Some of us feel well-rested after a solid eight hours of sleep. For others, closer to nine feels best. For others still, a little less will do. How much sleep we prefer to get is highly subjective. But how much sleep we need is a bit more concrete.

“Sleep time was one of the most visited pages on the NSF website, but it wasn’t really clear how those recommendations had been arrived at. ” Max Hirshkowitz, a sleep expert said.

To reassure that the information provided there was the most accurate and up to date, a group of 18 experts conducted a formal literature review. They focused on the body of research surrounding sleep duration in healthy human subjects that had been published in peer-reviewed journals between 2004 and 2014. Then they were able to fine-tune existing sleep duration recommendations as detailed below: Newborns (0-3 months): 14-17 hours (range narrowed from 12-18)

Infants (4-11 months): 12-15 hours (range widened from 14-15)

Toddlers (1-2 years): 11-14 hours (range widened from 12-14)

Preschoolers (3-5): 10-13 hours (range widened from 11-13)

School-age Children (6-13): 9-11 hours (range widened from 10-11)

Teenagers (14-17): 8-10 hours (range widened from 8. 5-9. 5)

Young Adults (18-25): 7-9 hours (new age category)

Adults (26-64): 7-9 hours (no change)

“It’s the first time that any professional organization has developed

age-specific recommended sleep durations” Hirshkowitz said, “It’s not an exact scie nce, but it’s a start. Like most things, it’s successive approximation that gets you to the goal. The first time somebody built a wristwatch, it wasn’t very good, but after hundreds of years of making precise changes, to have a timepiece that doesn’t tell time is pretty unusual. ” As more and more research is conducted

around sleep duration, subsequent minor changes will be made, he said, helping experts to zero in on the absolute best recommendations to give to patients. 【文章大意】本文中作者介绍了一些专家通过对发表在2004年到2014年期间杂志上对人们需要多长时间的睡眠给出的科学依据。
