It seems we're always being told to get more sleep. Studies suggest spending less time on sleep can lead to obesity(肥胖) and even cancer. You might even find yourself with a head full of false memories. But rarely does science explore the dark side of sleeping too much. That's because few of us in today's busy world have the luck of exploring that option.

In an August 2018 study, published in the Journal of the American Heart Association, researchers researched the sleep patterns of those“fortunate”few and found they may not be so lucky after all. In fact, they found people who get more than eight hours of sleep have greater health risk compared to those who sleep together less than seven hours. What's more, sleep-aholics-those who manage to get 10 hours a night-stand a 30 percent higher chance of dying compared to the seven-hour crowd.

The wide-ranging global study involved(涉及) more than three million people who self-reported on their sleep habits and came to an eye-opening conclusion: If you tend to sleep a lot, you may want to buy an alarm clock. As with all things in life, sleep is best taken in moderation（适度）.

You may be thinking: What if I only sleep in on Saturday and Sunday, am I still at risk? The answer is yes, according to a 2019 study published in Current Biology.　 Researchers discovered that even if a person sleeps more　 than seven hours on the weekends but still sleeps less than that on weeknights, they are at risk of gaining weight　 and developing sensitivity to insulin, which controls the level of sugar in blood.

For the study, 36 participants were divided into three groups that each had a different sleep schedule: nine　 hours every night, five hours every night, and five hours from Monday to Friday and sleeping much on　 weekends. People who get too much sleep tend to feel tired and lack energy. Also, both sleep-deprived（睡眠不足的) groups consume more food and gain weight.

1.Why is the harmful effect of sleeping too much seldom studied?

A.Few people have time to sleep too much. B.Lack of sleep causes much more harm.

C.It turns out to be a healthy sleep pattern. D.People's health has nothing to do with it.

2.What does the underlined words "those 'fortunate' few" in paragraph 2 refer to?

A.Those leading a relaxing life. B.Those getting too much sleep.

C.Those with less time to sleep. D.Those with no sleep problems.

3.What can be learned from the 2019 study?

A.Sleeping much is particularly beneficial to hungry people.

B.Many people sleep more on weekends than on weekdays.

C.An alarm clock of high quality is important for good sleep.

D.People who sleep much only on weekends also have health risk.

4.What is the main idea of the text?

A.It is necessary to save enough time for sleep.

B.Too much sleep can result in gaining weight.

C.Sleeping too much does harm to people's health.

D.People can avoid sleeping much by eating healthily.

HOW TO GET MORE SLEEP

Many studies warn that not having enough sleep may lead to serious health problems, affecting our daily life, work and study. You’ve probably known this for long, yet you still don’t get a full night sleep due to an incredible work schedule. So what can you do to make more time for sleep, and get a better night’s rest overall?

• Invest in a better-quality mattress. If you’re sleeping on a years-old, worn-out mattress(床垫), it’s no wonder why you wake up feeling tired in the morning. 1. With a new mattress that’s better suited to your sleeping habits, you’ll get to sleep faster and stay asleep consistently.

• 2. There are many habits that can affect how much sleep you get, including how much caffeine you consume throughout the day (and when you consume it — even a few hours before bedtime can interfere with sleep), whether or not you physically exercise, and how long you spend staring at a digital screen before bed.

• Take a closer look at your schedule.3. In Western culture, there’s a lot of pressure to fill up our schedules to seem important and socially integrated, so your daily activities might have some faults or unnecessary tasks that can be skipped or delayed. 4.

Sleep is even more important than you probably realized, but it’s entirely within your power to reshape your sleeping habits for good. Make sleep your first priority, scheduling time for it the way you’d schedule a meeting, and work the rest of your schedule around it. 5.

A.Watch your habits.

B.Some habits contribute to a good night’s sleep.

C.Without enough sleep, you could take more risks in your life.

D.A new mattress can be a big investment, but it’s almost worth the money.

E.Draw a line between professional and personal time, and make sleep a higher priority.

F.If you feel like you’re too busy to sleep, consider taking a second look at your schedule.

G.In time, it will become the new routine, and you’ll improve your health and productivity.

We tend to believe that older people are more positive and younger people are more sensitive to social cues (暗示).

Recently scientists investigated this idea by testing 10,000 men and women. They wanted to see if age affected a person’s ability to identify subtle facial emotions, such as fear and anger.

The researchers from McLean Hospital in the US used a Web-based platform to collect happiness data. It showed the participants two headshots (头部特写) of random people. They were then asked to identify which subject was angrier, happier, or more fearful. The research found that younger people were able to better identify angry and fearful facial cues than older people.

“From the previous studies , we know that the everyday experiences of an adolescent are different from an older person, but we wanted to understand how these experiences might be linked with differences in basic emotion understanding,” wrote Laura Germine, the study’s senior author.

But what is it that makes young people more sensitive?

“This is the exact age when young people are most sensitive to forms of negative social cues, such as bullying,” Lauren Rutter, the study’s lead author, told Science Daily. “The normal development of anger sensitivity can contribute to some of the challenges that arise during this phase of development.”

On the contrary, across the whole 10,000-person survey, researchers found no decline in the perception (感知)of happiness among older participants.

“What’s remarkable is that we see declines in many visual perceptual abilities as we get older, but here we did not see such declines in the perception of happiness,” Germine told Neuro Science News.

She added that these findings fit well with other research, showing that older adults tend to have more positive emotions and a positive outlook.

Following the paper’s release, Rutter told Neuro Science News that gathering their primary research online allowed the team to tap into a “much larger and more diverse sample set” than previous studies.

1.What is the result of the research?

A.We are often bullied while young.

B.We become less positive as we get older.

C.The younger we are, the happier we feel.

D.The younger, the more sensitive; the older, the more positive.

2.What makes young people more sensitive according to the text?

A.Their family backgrounds. B.Their negative experiences.

C.People around them. D.Their visual perceptual abilities.

3.How does the author support the theme of the text?

A.By giving examples. B.By stating arguments.

C.By explaining statistical data. D.By providing results.

4.Where is the text most probably taken from?

A.An announcement. B.A science magazine.

C.A travel guide. D.An official report.

We've all heard it before： to be successful, get out of bed early. After all, Apple CEO Tim Cook gets up at 3： 45 am, Fiat CEO Sergio Marchionne at 3： 30 am and Richard Branson at 5： 45 am ﹣and, as we all know, "the early bird's catches the worm. "

But just because some successful people wake up early, does that mean it's a trait most of them share？ And if the idea of having exercised, planned your day, eaten breakfast, visualized and done one task before 8 am makes you want to roll over and hit snooze till next Saturday, are you really doomed to a less successful life？

For about half of us, this isn't really an issue. It's estimated that some 50% of the population isn't really morning or evening﹣oriented, but somewhere in the middle. Roughly one in four of us, though, tend more toward bright﹣eyed early risers, and another one in four are night owls. For them, the effects can go beyond falling asleep in front of the TV at 10 pm or being regularly late for work.

Numerous studies have found that morning people are more self﹣directed and agreeable. And compared to night owls, they plan for the future more and have a better sense of well﹣being.

Although morning types may achieve more academically, night owls tend to perform better on measures of memory, processing speed and cognitive （认知） ability, even when they have to perform those tasks in the morning. Night﹣time people are also more open and more creative. And one study shows that night owls are as healthy and wise as morning types ﹣and a little bit wealthier.

Still think the morning people sound more like CEO material？ Don't set your alarm for 5 am Just yet. As it turns out, overhauling （全面改革） your sleep time may not have much effect

"If people are left to their naturally preferred time, they feel much better. They say that they are much more productive. The mental capacity they have is much broader, " says Oxford University biologist Katharina Wulff. On the other hand, she says, pushing people too far out of their natural preference can be harmful. When they wake early, for example, night owls are still producing melatonin （褪黑素）. "Then you disrupt it and push the body to be in the daytime mode. That can have lots of negative physiological consequence. " Wulff says, like a different sensitivity to insulin and glucose （葡萄糖） which can cause weight gain.

1.What does the author do in the first three paragraph？

A.raising the problem→analyzing the problem → solving the problem

B.leading in the topic→challenging a viewpoint → discussing about the topic

C.presenting a viewpoint → providing supporting proofs→making a conclusion

D.introducing a viewpoint →raising the question→presenting author's viewpoint

2.What can we know from the 4th and 5th paragraph？

A.Morning types tend to have clear goals and better mood.

B.To beat night﹣time people ask them to do math calculation in the morning.

C.Night owls tend to sacrifice their health for their wealth.

D.Neither night owls nor morning persons perform better than the middle ones.

3.Which of the following does Katharina Wulff support？

A.Don't fall sleep in front of the TV.

B.Avoid being regularly late for work.

C.Stop setting your alarm for 5 am.

D.Better not overhaul your sleep time.

4.Why does the author write this article？

A.To explain why some people are more successful.

B.To compare the differences between early risers and night owls.

C.To advise people to get up neither too early nor too late.

D.To argue against this view that the Carly bird catches the worm.

Do what you love and love what you do, and success will come? Well, we wish. 1.It takes more than just passion to succeed in anything.

Passion is just emotion; care is an action.

Wishing hard and wanting something really badly won’t give you anything. Passion is a barely controllable emotion, and emotion is not always reliable. 2.

In today’s world where people always talk about finding your passion, it still seems vague (模糊的) to many. On the other hand, if you’re asked to find something you care about, it’s easier for you to take action.

3.

There’s a lot of work to do besides being enthusiastic. For example, you can be enthusiastic about painting, but if you don’t have any art sense and painting skills, you can hardly become an expert in painting. 4.The belief that you’ll do it well anyway as long as you like it is just an illusion.

Learn not just what you care about, but what’s around that too.

When you’ve got your focus, try to map out the skills you need to get better at that. When you have the learning plan ready, apply that course you need, get yourself the tools required and start learning and practicing.

Success is a way to go, but you can start right now.

5.But if you’ve already got your passion, it will be good enough to make that your foundation and motivation to keep moving. Start mapping out the skills you need and take actions, Instead of passively letting your passion wander around, be active and do something that will push you forward.

A.Care is different, it implies actions.

B.“Like it” doesn’t mean “Good at it”.

C.Passion alone doesn’t guarantee success.

D.However, reality is not as simple as we want it to be.

E.You are good at something and you need the world to know.

F.Desire to make a difference in the world with your strengths.

G.To become an expert, you need to be always learning and improving your skill.

Tests, after-school activities and problems at home can increase stress for students. But research now suggests that the main reason for the students’ rising anxiety levels is something else.

A psychology professor Jean Twenge said “What a lot of teens told me is that using social media and their phones seems forced. This use of phones has led to a loss of sleep and face-to- face interactions.” Last year, in the journal Pediatrics three researchers wrote that too much social media use might contribute to the development of mental health problems in teenagers, such as loneliness, depressive symptoms and anxiety.

Researchers are still not sure whether phones cause student depression or depression causes phone use. Yet 70 percent of teens see anxiety and depression as major problems among their peers, according to a February Pew Research Center report.

Schools are starting to take steps to deal with the problem. Many public schools pay outside companies to watch students’ social media activity for signs of pain. Some schools have organized some events in which people do not use their electronic devices. Belfast Area High School in Maine had one such event in April. About 20 percent of students and school employees took part, demonstrating the influence that the technology has on their daily life.

Emily Mogavero, a 17-year-old student in New York, said “I definitely feel stressed to keep up my information and stuff. It kind of worries me that I’m on my smart phone so long.” Mogavero said she sometimes puts her phone out of reach or powers it down so she doesn’t hear anything.

Some parents are not letting their children get smart phones until they grow up. A teacher, Erin Schifferli, says her 12-year-old daughter, Aeva, won’t get a phone until she is 16 years old. Deirdre Birmingham of Montclair signed on a campaign called “Wait Until Eighteen” because she didn’t think her video game-loving 10-year-old son was ready for a smart phone.

1.What’s the main cause of teenagers’ mental problems according to the text?

A.Being addicted to social media. B.Being lacking in enough sleep.

C.Too much homework. D.Too many activities.

2.What does Mogavero think of using smart phones too much?

A.It is necessary. B.It is worrying.

C.It is reasonable. D.It is meaningless.

3.How can parents deal with the children’s problem?

A.Help their children grow up quickly.

B.Stop their children using smart phones.

C.Pay more attention to children’s study.

D.Sign on more campaigns to make a difference.

4.What can we learn from the text?

A.Over-using phones influences teens’ social interactions.

B.70 percent of people have anxiety and depression.

C.Almost all the students liked the schools’ activities.

D.The findings of the research are very definite.

As computer games get to look more lifelike, it seems that their violence is spilling over into real life. It is reported that some dozens of children have been murdered since 1997, which has been linked to all obsession (着迷) with violent video games. Recently the parents of a 14-­year-­old murder victim in the UK blamed the killer's obsession with the game Manhunt, causing a government review of legislation (立法) to protect children.

Psychologists think there may be many reasons why violent games are more harmful to children than violent movies. Firstly, players are actively involved in violence, and may begin to see using weapons as second nature. Secondly, violent games provide repetitive aggressive (侵犯的) experiences that are rewarded by more killing.

Many studies have shown that people who play violent games regularly are more likely to show high levels of aggression. For instance, in 2000, scientists in Iowa State University found that people who played violent games were more likely to admit involvement in aggressive behaviors, including assaults (侵犯人体罪) or robberies.

A study of 13 to 14-­year­-old children showed that more than half had played games recommended only for over­18s. The more violent the games they played, the more they considered physical aggression to be acceptable. Besides, children who play violent games are more prone (有做……倾向的) to arguing with teachers and fighting.

Experimental studies have also hinted at a possible link. In one, scientists asked a group of students to play a violent game, while another group played the non­violent. Those who played the violent games were faster to react to aggressive words subsequently (随后) flashed on screen.

1. We may infer from the first paragraph that 　　　.

A. computer games have little to do with violence in real life

B. Manhunt has resulted in the death of one of its plays

C. lifelike computer games are forbidden in the UK

D. legislation to protect children in the UK still needs improving

2. Violent games are more harmful to children than violent movies because 　　　.

A. violent movies are not so attractive to children

B. the viewers can't take part in violent movies

C. violent movies are not popular with children

D. children can win awards in violent games

3. What will be probably discussed in the paragraph following the passage？

A. Further research on the harm of violent games.

B. Further differences between violent game and non­violent games.

C. Ways to protect children from violent games.

D. The result of more experimental studies.

4. What would be the best title for the passage？

A. Games and Murder

B. Should Computer Games become lifelike？

C. Legislation, effective or not？

D. Violent Games and Non­violent Games

In today's fast paced，high stress world people are working longer hours than ever，and often exhaust themselves at day's end in front of the television to relax enough to begin again in the morning. However，television watching，for most people，does not really lower stress. Studies show that TV viewing more than an hour or so actually creates stress and，especially in women，may lead to the blues. Most individuals are unaware that doing some exercise after work makes them more energetic since it increases energy levels.

Wise use of free time does not mean getting an advanced degree，although the mental encouragement gained through education is unbeatable in keeping your mind active. Learning new things nearly always adds a spark to your daily life，especially if it is a favorite topic，such as sport，fashion，or art. Also，look through your bookstore or library to find books on your interests. Try to replace a half hour TV watching with reading.

It is reported that in the United States recently，many individuals have as few as two good friends. Long work hours and car commute act to separate people from each other. This separation is deadly. Find ways to meet people at the end of the day and on weekends. Often this can be best done by combining activities，such as by joining a walking group to get both exercise and companionship. Taking a class will lift your spirits and allow you to meet others with similar interests. Hobbies are great for reducing stress and provide another opportunity for social interaction.

Using your free time to aid your health may include these elements and many more，such as going to concerts and spending time with family. Overall，the key is to spend less free time being passive. The best ways to use free time are to be mentally and physically active，spend some time outdoors，and interact with other people on a regular basis.

1.What can we learn from the passage?

A.Watching television may cause women to feel depressed.

B.Finding interests and hobbies in common means taking a class.

A.The arrangement to work every day.
