Teens and their teachers know well that early-morning classes can be tiring. Doctors now have a solution: for better teen health, push the sleep button on school start times. Janet Croft, who studies teens and sleep at the Centers for Disease Control and
Prevention(CDC)in Atlanta high schools, says, “Most teens are actually brain dead when they go to these early classes. Too many students start their day as walking zombies(僵尸).”
One report stresses the importance of sleep for teens and describes the dangers from not getting enough sleep. Studies in the past have shown over and over that teens lacking sleep face higher risks of being overweight and being frustrated.
Many teens get too little sleep because they attend middle and high schools that start earlier than 8:30 am. According to the American Academy of Pediatrics(AAP),those early start times throw off a student’s internal body rhythm, called the circadian clock(生物钟).Too little sleep disturbs that clock and causes problems.
The study conducted by the National Sleep Foundation found that nearly 6 in every 10 middle school students and 9 in 10 high school students are sleeping too little. Yet many parents aren’t aware of this. In the same study,7 of every 10 parents said they believed their kids did sleep enough. That study shows too many parents are unaware of the science on teen-sleep needs, says Owens.
Kyla Wahlstrom, a former teacher, who has spent a lot of time with teens lacking sleep, says: “An incredible number of students are either sleeping at their desks or sitting there like a lump, not asking questions or raising their hands.”
Getting enough sleep can help a teen on the inside, too. Several studies have shown that children and teenagers who don’t sleep enough are more likely to become obese, or extremely overweight. Teens lacking sleep also are more likely to suffer from anxiety, depression and mood disorders. It’s time to recognize how important sleep is, particularly to teenagers.

When temperatures rise, many people swim to beat the heat. But swimming does a lot more than that. It is a great workout for the whole body. Health experts at the University of California, Berkeley state that swimming is a great way to stay in shape.
Swimming is a very good high-intensity cardio exercise (高度有氧运动). Cardio involves the heart, lungs, and circulatory(血液循环的) system. The Berkeley experts say swimming can increase your heart rate and exercise your lungs. Some high-intensity cardio exercises, such as running, can improve your health but can also be likely to hurt your body. Swimming, on the other hand, is beneficial to the body and people often use it to recover from injuries.
Paul Waas, a coach and former competitive swimmer, says that swimming is more beneficial to the body than other sports because it is low-impact. A mother called Paloma with two daughters says that for her girls, swimming has been more beneficial to the body than some other sports. She said, “So far, I think it’s been good for their bodies. It’s a high-intensity cardio exercise, as you know. But it spares their knees, their joints, and so on. So it’s rare to get injured in swimming.”
The coach adds that swimming is a great exercise for kids who grow a lot in a short amount of time. Coach Waas said, “Swimming is really good for kids who are growing fast. Their bones might be hurting and they’re suffering from serious pain all the time. And then they get in the pool and, you know, they can float and stretch out a little bit and it reduces that as well.”
People who are overweight can also find relief through swimming. Their weightlessness in the water can help them to avoid injury as they exercise.

2.What’s Paul Waas’s attitude towards swimming?
A.Positive. B.Negative. C.Doubtful D.Worried
3.What does the underlined word that in Paragraph 4 refer to?
A.Floating and stretching out. B.Fast physical growth of kids.

“Quick, quick, slow, slow,” my husband said as I was trying to focus. We frequently stepped on each other’s feet. Both of us were being rhythmically(有节奏地)challenged, and we figured a series of lessons might help us look somewhat skilled on the dancing floor. However, it didn’t.
It didn’t matter that the lessons didn’t pay off. Our learning something new together gave us a string of good memories, such as taking a Thai cooking class on a cold Chicago night and learning how to make a classic cocktails in a common bar. These experiences are my best memories from the past 10 years. We always have such a great time when we’re trying something new together. It seems to have strengthened our relationship, and makes me feel like we have a closer connection.
It turns out my theory as such is backed by research. One study shows that learning new things with your spouse(配偶), friends, or partners, can strengthen your connection or friendship. But how exactly does this work? The key is weakness. “Learning new things together strengthens connection because it is at those moments that we can show our weakness to one another,” says Dr. Hisla Bates. “When we are learning a new task, misfortunes and failures are sure to happen. In those moments when we fail, the other party can be there in favor of us. We can Work together to find a solution, and working together helps deepen the connection.”
The benefits gained from learning new things with your partner can come from activities as small as hiking, trying a new diet, going boating in the local lake or taking a fitness class together. You don’t have to bungee jump or skydive to grow closer. Try selecting activities that both partners are unfamiliar with, as this will ensure you’re on the same page.
Trying to learn something new together once a month will benefit you and your spouse or friends . Overall, some of my best memories with my husband are the moments when we are learning something new together.
