You’ve got to get an early start tomorrow, but you’re not sleepy yet. Blame your brain, at least in part. Yet that same brain is still under construction. And much of that important work takes place while you sleep. Here’s what’s happening and why it matters.

Today’s lifestyle is one reason for late bedtimes. Many teens don’t finish with after-school activities, part-time jobs, dinner, and homework until 10 p.m. or later. Add in some time for relaxing, especially time for screens, and bedtime may not roll around until 11 p.m. or nearly midnight. In response, the brain cuts back melatonin(褪黑素), a hormone that promotes sleep. Even without modern technology, though, teens change their daily cycle for sleeping, waking, and various other activities.

The rest of the world doesn’t change, however. So most teens must head to school before they’ve gotten the 8.5 to 9. 5 hours of sleep recommended by the American Academy of Pediatrics. And that’s a serious public health problem. For one thing, lack of sleep makes it harder to pay attention. When studies compared teens who had earlier and later school start times, they found that those who had more time to sleep did better in class. They also suffered fewer accidents in sports, driving, and other activities. Lack of sleep could also hurt mental health. Studies have found an inverse correlation(负相关)between teens’ amount of sleep and depression and other mental illnesses. As sleep time went down, the risks for the mental illnesses went up. Beyond that, teens lacking in sleep report more relationship problems and feelings of inadequacy.

Lots of issues remain for sleep researchers to explore. For now, though, studies are clear:Teens’ brains need sleep.

1. Teen’s lifestyle today most likely leads to _______.
A.the change of daily cycle
B.the rise of melatonin release
C.the growth of relaxing time
D.the decrease of technology use
2. With the amount of sleep decreasing, teens may experience _______.
A.poorer concentrationB.lower illness risk
C.stronger relationshipD.greater emotional change
3. The author probably supports the idea that _______.
A.sleep issues are extremely hard to solve
B.school time is generally impossible to adjust
C.enough sleep is clearly beneficial to teens’ health
D.the brain is chiefly responsible for teens’ sleep problems

【推荐2】Keep Sight of Dry Eye

Do your eyes feel uncomfortable or dry? If so, you might have dry eye syndrome (综合征).     1     It can affect the enjoyment of social activities and your ability to focus on your studies. But solutions for dry eyes do exist, so read on.

In the past, dry eye syndrome was mainly a condition experienced by older adults, but it now affects many young people as well. Dry eye often results from overuse of computers or smartphones, which causes the user to blink (眨眼) less. Since blinking helps keep our eyes wet, a lack (缺少) of it can lead to dry eye.     2     As a result, those who spend a lot of time indoors are particularly at risk. Finally, wearing a medical mask can cause dry eye, since breathing with a mask on can force air out through the top of the mask and into our eyes.

    3     The first step toward prevention is cleanliness. When you wash your face, clean your eyes with a mild soap. Then, cover your eyes with a warm, wet cloth. Preventing dry eye also means avoiding tiredness in the eyes, so take frequent breaks when using your computer. While you’re on a computer break, focus on blinking, making sure that you close your eyes fully on each blink.     4     Another way to prevent dry eye is to drink more water. For good overall health, experts advise drinking 8 to 10 glasses of water per day, which will increase tear production.

If you suffer from dry eye syndrome, these steps can go a long way toward making your eyes feel better. However, if the problem doesn’t go away, then it’s time to see a doctor.     5    

A.After all, your health is worth keeping an eye on.
B.Blinking can help protect the surface of your eyes.
C.This happens when you don’t produce enough tears.
D.Air-conditioning and fans also contribute to dry eye.
E.Limit screen time and take breaks from staring at screens.
F.Treatments for dry eyes can include eye exercises and eye drops.
G.All it takes is a few lifestyle changes to prevent and treat dry eye syndrome.

文章大意:本文是说明文。文章主要说明了研究表明饭后散步有助于稳定血糖,且介绍了饭后散步的好处以及相关研究。

【推荐3】For centuries, people in the sunny Mediterranean (地中海) would get up after long, relaxing meals and take a walk, often to the town square to see neighbors and socialize. Walking is so much a part of the lifestyle that it is seen as the most important part of the super-healthy Mediterranean diet.

Studies have found that it may be one of the reasons the Mediterranean diet can reduce the risk for some diseases like diabetes, high cholesterol, heart disease, stroke and some cancers — all the while strengthening bones, improving brain health, preventing dementia(痴呆) and helping with healthy weight loss.

Now you can add another reason to take a post-meal walk — it may lower your blood sugar. That trip doesn’t need to take up a huge amount of your time either: Walking as little as two to five minutes after a meal can do, according to a 2022 study in the journal Sports Medicine.

Standing after a meal can help, too, but not as much as putting one foot in front of the other, said study coauthor Aidan Buffey, a doctoral student in sport sciences department at the University of Limerick in Ireland.

“Standing on and off throughout the day and after meals reduced blood sugar on average by 9.51% compared to long hours of sitting. However, light-walking throughout the day saw a greater reduction of blood sugar by an average of 17.01% compared to long hours of sitting,” Buffey said.

“This suggests that breaking long hours of sitting with standing and light-walking throughout the day is good for blood sugar levels. Standing is good, but walking is better,” he added.

1. What is the purpose of Paragraph 1?
A.To introduce a lifestyle.B.To warn the readers.
C.To lead in the topic.D.To prove an opinion.
2. What benefits can the Mediterranean diet bring to people EXCEPT        ?
A.Losing appropriate weightB.Making bones stronger
C.Preventing the risk for diseasesD.Improving brain health
3. How did Aidan Buffey draw his conclusion?
A.By doing surveys (调查).B.By comparing the data(数据).
C.By doing experiment.D.By referring to other studies.
4. What is the best title for the text?
A.Walking can help lower blood sugarB.There are reasons to stick to walking
C.Mediterranean diet is super healthyD.Long hours of sitting after meal is a bad habit
