1 . Loud noise can be very damaging to your hearing, whether it’s a loud burst or years of exposure. Approximately 15 percent of adults 18 years of age or older report some trouble hearing.     1     The good news is that taking action now may protect you from hearing loss later in life.

Get a baseline hearing test. Most people have never had a hearing test.     2     At your next physical, ask for a hearing test as part of your routine checkup. A hearing test gives your audiologist a baseline that they can compare with future results to monitor the progression of hearing loss.

    3     While you are watching TV or using mobile devices, keep the volume at a comfortable level. It should be loud enough to make sure you can hear very well, but not so loud that when you leave the room, you can still hear it from another part of your home.

Wear protective hearing devices. Think ear protection before you’re exposed to any noisy environment, such as rock concerts or airports. When you are in a noisy environment, wear protective hearing devices such as earplugs or protective earphones.     4    

Have proper earphones. If you often listen to music on earphones using a portable music or video device, it’s a good idea to have earphones that fit the unique shape of your ear canal, and block outside noise.     5    

A．The risk rises as we age.

B．Monitor the volume of your devices.

C．However, it benefits you to go against that trend.

D．Meanwhile, you will find the sound truly superior.

E．You can find them at your local drugstore or music supply shop.

F．Think about buying appliances and devices that have low noise ratings.

G．You must do something to keep age-related hearing loss from getting worse.

4 . Researchers at the University of Arizona have been studying the effects of green light therapy on those suffering from migraine (偏头痛). In September, they completed their first clinical study and the results are very encouraging. They found that green light therapy is extremely beneficial to those who suffer from headaches. It not only reduces the intensity of the pain, but it also decreases its frequency by 60 percent, significantly improving patients’ quality of life.

According to the Migraine Research Foundation, migraine is the third most common illness in the world, affecting one billion worldwide, including men, women, and children. Additionally, it is the sixth most disabling illness in the world and more than 90 percent of the sufferers are unable to carry on with their normal activities during their sufferings. And when it is actually treated, medication overuse can lead to episodic (偶尔发生的) migraine turning chronic (慢性的).

According to Science Daily, the recent clinical study included 29 patients who suffer from episodic or chronic migraine. They have tried but failed in several traditional therapies including Botox injections and oral medications. In the study, participants spent two hours at home each day staring at a green-light LED. They did this for ten weeks, reporting the number and intensity of headaches they had.

Dr. Patwardhan, co-author of the study, said that the green light discharged by the LED greatly helps those who do not want to take medicine as well as those who do not respond to medications. “The beauty of this approach is the lack of associated side effects,” Patwardhan explained. But that’s not all. The participants also reported significant improvements in sleep quality and in the ability to perform everyday normal activities such as exercise and work. And none of them reported any side effects.

As the study reveals, green light treatment might be an unprecedented (前所未有的) alternative for migraine sufferers.

1. What can we learn from the research?

A．Migraine sufferers unable to live a normal life makes up about 60%.

B．Episodic migraine can be treated more easily than chronic migraine.

2. What were the 29 participants asked to do in the study?

A．Take some traditional medicine daily for ten weeks.

B．Use a green-light LED the whole night at home for ten days.

C．Receive an injection each day for two months.

D．Look at the green light for two hours per day for 70 days.

3. Which of the following can replace the underlined word “discharged” in Paragraph 4 ?

A．lit up

B．put out

C．taken in

D．sent out

4. What was Patwardhan’s attitude to the new treatment?

A．He thought it had side effects.

B．He agreed it was of great benefit.

C．He worried it might affect sleep.

D．He wondered if it hurt eyes.

5 . Three Simple Tricks Improve Your Mornings

Most people are familiar with the feeling of being torn out of heavy sleep by the sound of their alarm clock. But why do we feel fresh and fully rested some mornings, while on other days we barely have the energy to turn off the alarm clock?

Scientists have carried out a study of 833 adults. The results show that we can control how fresh we feel in the morning if we follow three simple pieces of advice.

As in the sleep research, the test subjects wore special watches that monitored their physical activity and the quantity and quality of their sleep. They were also served different breakfasts, and then through the day the scientists monitored their blood glucose (葡萄糖) levels while those who took part in the research kept a chart of their energy levels through the day. Many of the subjects were twins, helping to rule out genetic differences.

The data showed that the secret behind energetic mornings is a three-stage solution made up of plenty of exercise the previous day, enough sleep, and then the right breakfast.

One researcher explains that each of these three factors are important ingredients if you want to wake up feeling fresh and fully rested—and able to continue feeling relatively energetic for the rest of the day. “If you sleep more than you usually do, you will feel more awake,” he explains. “If you are more physically active the previous day, you get the same effect. Both factors cause improvement.”

The worst breakfast proved to be food with high sugar content; this made those who took part in the research feel sleepy and low on energy for the rest of the day. The best way to start a new day was to eat breakfast with a high content of whole grains and vegetables.

Perhaps unsurprisingly, the quantity of sleep was also a key factor in mood. The results proved that 7—9 hours of sleep are necessary to shake off morning sleepiness.

Scientists do not yet know why exercise seems to improve our awareness and ability to wake up re-energized. But they stress that exercise is an important key to our health and mood in general.

6 . Easy Ways to Protect Your Eyes From The Harms of Digital Devices

Most people spend a large amount of time in front of digital devices without protective glasses. Unfortunately, they are simply unaware of the harmful effects that these digital devices have on the eyes.     1    

1. Exercise your eyes

If you keep your eyes glued to a digital device without blinking or flexing them a bit, they will get accustomed to that device distance.     2     You should try to move your eyes around more, changing their position or flexing them every 20 minutes or less.

2. Adjust your screen lighting

    3     If you are in a brightly lit room, you will need to increase your screen’s brightness setting. If you are working in a dim room, you will need to decrease your screen’s light settings.

3.     4    

Your doctor may recommend you use specialized glasses to reduce glare and eyestrain from your digital device. These glasses will help protect your eyes from harmful glare whenever you use them. Keep in mind that reading glasses don’t protect your eyes from this glare.

Never let an eye problem be a hindrance to your work or fun if you are a regular user of digital devices.     5    

A．Expose your eyes to the daylight

B．Ask your doctor to recommend specialized glasses

C．Your screen lights should be adjusted in relation to your environment.

D．You will experience problems when trying to focus on anything farther or closer to the device.

E．Optometrists (验光师) recommend that you sit at least an arm’s length away from your digital screen.

F．By following the above tips, you will help protect your eyes from the problems brought about by digital devices.

G．Below are some easy tips that you can incorporate (使并入) into your daily routine without throwing away your digital devices.

7 . How to Sleep Better

What you do (or don’t do) before bedtime has significant impact on the quality of your sleep.     1     Here are a few suggestions:

Go from light to dark. Darkness stimulates production of the sleep hormone.     2     And think about investing into warm light that you can use in the bed-room before bedtime.

    3     Keep the bedroom a technology-free zone as the light from electronic devices can disturb your sleep. If you need to work, wear blue light blocking glasses(also known as computer glasses)throughout or before you sleep to prevent sleep disruption.

Find an activity that helps you to wind down. This could be anything that calms you down, and reduces thinking. For example, listening to soothing (柔和的) music, taking a hot bath, reading or meditating.

Keep any electronics you have on the other side of the room or outside the room. One of the most harmful things that can disrupt your sleep is the notifications you get from your smartphones.     4    

Create a bedtime routine. A night routine is a couple of things you do prior to going to bed. By doing these things every night, you’ll have a more restful and high-quality sleep.

Adjust your sleep temperature. The ideal temperature for sleep is 60~67 Farenheit (华氏度). This may be cooler than what most people are used to.     5     Rule of thumb: sleeping in cooler temperature is better for sleep quality than warmer temperature.

A．Avoid screens.

B．Sleep better from now on.

C．Turn off unused light around the house.

D．The higher the temperature is, the better you sleep.

E．The simplest way to avoid this is to keep it away from you.

F．Many times, it can be the difference between staying up until 4 am and sleeping like a baby.

G．But keep in mind that our body temperature changes once we fall asleep

10 . A lab-based sleep study found that people who were sleeping fewer than six hours a night for two weeks — and who thought they were doing just fine — functioned as badly on cognitive (认知的) and reflective tests as people who were deprived of (被剥夺) any sleep for two full nights. That’s because the brain needs uninterrupted sleep cycles to absorb fresh skills, form key memories, and repair the body from the day’s wear and tear. During sleep, your body is literally repairing and restoring itself on a cellular level.

A long-term lack of sleep therefore impacts your ability to pay attention, learn new things, be creative, solve problems and make decisions. Even skipping sleep for just one night disrupts functioning. Mounting evidence shows that sleep influences the long-term risks of memory issues, cognitive decline.

A research suggests that recovery from sleep deprivation (many days of it, in particular) may not be so easy. The effects of sleep deprivation on the brain’s attention and cognitive processing abilities may linger as long as a week after we’ve returned to a regular sleep routine, warns a study.

Want to live longer? Then prioritize sleep and following five good sleep habits in your life- falling asleep easily, staying asleep, getting seven to eight hours of zzz’s, waking up rested and abandoning sleep medicines — People were scored on how many of the five habits they had. Compared to individuals who had zero to one favorable sleep factors, those who had all five were 30% less likely to die for any reason. Obeying the five good sleep habits added nearly 5 years to a man’s life expectancy and almost 2.5 years to a woman’s life, the new study found. However, according to researchers, the reason for the obvious gap between men and female needs further studies.

Make sure you get a full seven to eight hours of sleep each night. That’s tough for many people. It’s important to go to bed at the same time on most nights and get up at the same time in the mornings — even on weekends and holidays. Make sure your environment is ideal — cooler and darker is better — and block noise. Set up a sleep routine, with no blue lights or distractions at least an hour before bedtime. Try meditation, yoga, tai chi or warm baths — anything that relaxes you is great. Anyway, you can’t attach too much importance to your sleep.
