文章赏析
Birds do it. Bees do it. People do it, though often less than they would like to. Owls do it in the daytime. Sleep is an ancient, universal experience.
But partly because it is the order of the day, for a long time sleep was a subject that scientists had not woken up to. It is only in the past half-century or so that it has attracted the attention of dedicated researchers. A new book from Kenneth Miller, a science journalist, sets out to record the field's short but fascinating history.

explain.

Its contents range from the discovery of rapid-eye-movement(REM) sleep and circadian rhythms ——the biological clocks that govern humanity's days—— to the effects of sleep deprivation (which can be fatal, at least in lab animals). It also explores the purpose, if any, of dreams.

Sleep is a state of lowered consciousness and reduced metabolism which takes up about one third of a person's life. Two distinct types of sleep have been recognized: REM(rapid eye movement) and NREMnon-rapid eye movement). The latter, which accounts for the major part of sleep, starts with drowsiness; brain waves become increasingly deeper and slower until brain activity and metabolism fall to their lowest level. In REM sleep, the brain suddenly becomes more electrically active, its blood flow increases, the eyes move rapidly and dreaming occurs.

Discoveries often lead to new questions in turn. That is why neat, tidy endings are hard to achieve in most science books; this one is no different.Despite all the progress of the past 50 years, scientists are still unsure what sleep is for. The fact that it is so widespread suggests it is vital.
But why evolution would see fit to produce animals that must spend large amounts of their time unconscious and unable to respond to threats is still a mystery researchers are trying to solve.For anyone curious about asking the right questions, however, Mr Miller's book is a good place to start.

外刊阅读练习——深度阅读的时代结束了？
P1: Digital reading appears to be destroying habits of "deep reading".Amazing numbers of people with years of schooling are in effect illiterate.Admittedly, some people have been complaining about new media since 1492, but today's complaints have an evidential basis. Ljubljana Reading Manifesto says, "The digital area may lead to more reading than ever in history, but it also offers many attractions to read in a shallow and scattered （ 碎片化的）manner— or even not to read at all. This increasingly endangers higher-level reading."
adj.文盲的
诚然

1. What is the advantage of the digital reading
A. It makes more poeple start to read widely.
B. It makes more poeple begin to think deeper.
C. It helps the young to make use of the Internet.
D. It helps poeple take advantage of their spare time.

P2:Digital literacy has changed reading. When you read a book on paper, you can be entirely inside the experience, absorbing hundreds of pages to capture the world's complexity. Online, says Maryanne Wolf of UCLA, we are "skimming, scanning, scrolling. The medium is the message: doing deep reading on your phone is as hard as playing tennis with your phone. Recently, a bright 11-year-old told me I was wasting time on books: he absorbed more information faster from Wikipedia. He had a point.But digital readers also absorb more misinformation. And they seldom absorb nuanced ( 微妙的) ideas.

P3: In the white paper that underlies the Liubljana Reading Manifesto, experts catalogue the passive parts of digital reading: "Recent studies of various kinds indicate a decline of... critical and conscious reading, slow reading, non-strategic reading and long-form reading." In the 2021 international PISA survey, 49 percent of students agreed that "I read only if I have to", 13 percentage points higher than in 2000.

P4：As professors from Northwestern University foresaw in 2005, we are returning to the days when only an elite（精英的） “reading class” consumes long texts - despite more people spending longer in education and book sales remaining robust.
P5：People who lose higher- level reading skills also lose thinking skills. That's horrible, because "higher-level reading" has been essential to civilization. It enabled the Enlightenment, and an international rise in sympathy for people who aren't like us.

课后作业
Good morning everyone!
What seems beyond dispute is that sleelping plays an essential rule in our daily life. But with our increasing academic pressure, how do we keep a balance between study and rest Some relevant recommendations are as follows.
To begin with, not only should we have a efficient study method but also a serious time table is required. Additionally, the evidence that the electronic products may influence our sleeping indicates that the screen time ought to be avoided before bed. Last but not least, if time permits, taking a short sleep at noon will also contrtibute to our spirit, making us more energetic.
Only when we have a balance between study and sleep can we have a better experience in this special and stressful period.
Thank you for your listening.
