1 . Perhaps you use your headphones to enjoy music and peace and quiet during the day. But you may be neglecting the dangers of hearing loss with headphones.
In fact, headphones are not a bad thing. They can bring peace, allow for better musical enjoyment, and even protect your ears from higher decibels(分贝).
How long should you wear your headphones every day? The answer is, according to the World Health Organization, one hour per day.
Then, how do you set the safest volume for your headphones? With headphones, it depends on the type you’re using and your environment. To test things out, you should take them off your ears and extend them in your hands out in front of you.
| A．This might seem unreasonable to you. |
| B．At times, hearing loss isn’t permanent. |
| C．l in 5 teens will have some types of hearing loss. |
| D．What’s more concerning is what that means for children. |
| E．It’s the duration and volume that cause the problem, however. |
| F．If you still hear your music clearly, you need to turn them down. |
| G．It’s a wonderful thing to shut out the rest of the world and enjoy your music. |
2 . Three tips for protecting your eyes during the winter
We usually worry about staying warm during the winter months, and think less about protecting our eyes.
Tip 1:
During the winter, our eyes are often exposed to blowing, dry, hot air that can cause them to become dry. Here are a few treatments:
Tip 2: Wear sunglasses with UV (紫外线) protection.
UV rays in the winter can harm our eyes.
Tip 3: Goggles (护目镜) protect in many ways.
Goggles not only protect our eyes from UV rays, but they also help keep our eyes from drying out from the winter wind. In addition, think about all those branches, leaves, and dirty snow that can severely injure our eyes upon contact.
| A．Clean your eyes carefully |
| B．Don’t let your eyes dry out |
| C．Goggles protect the eyes from the wind |
| D．Keep eye drops at hand to wet your eyes |
| E．It is wise to wear quality goggles |
| F．In fact, they can do even more harm when they’re reflecting (反射) off snow |
| G．However, the winter months can be as hard on our eyes as the summer months |
3 . Where would you be without your legs and feet? They do a lot to get you where you need to go.
But sometimes, kids have problems with these important body parts. Their legs and feet might look different or might not work exactly the way they should.
Pigeon Toes
Pigeon toes, or inwardly turning toes, is a common foot condition in kids. It occurs when the front of the foot is turned inward, facing the other foot.
When someone stands with the feet and ankles together but the knees widely apart, we call that being bowlegged. Many babies are born bowlegged because their legs were folded tightly across their bellies while they were growing inside their mom. Bowlegs usually straighten once babies with this condition start to walk and their legs bear weight. By the age of 3, most kids grow out of the condition.
Knock-Knees
Knock-knees is a condition where the legs curve in at the knees so much that the ankles are separated.
Flatfeet
| A．Bowlegs |
| B．Full Arch |
| C．Stand sideways in front of a mirror. |
| D．Boys and girls both experience pigeon toes. |
| E．In other words, if your feet are flat, they’re fine! |
| F．The good news is that these problems usually aren’t serious. |
| G．Lots of kids become knock-kneed between the ages of 3 and 5. |
4 . The world has many beautiful sounds. we can hear the songs of birds and laugh of people. We can listen to cool music and news reports. And all this is due to(归功于) our ears! They bring us a world of sounds.
But some people can’t hear any sound at all. Some are born deaf. Others can hear well in their childhood, but too many loud sounds hurt their ears later on.
In China, 6 children out of 1000 have hearing problems when they are born. They can not hear ordinary sounds clearly. Children who have hearing problems usually also have learning problems at school.
A lot of things can cause hearing problems. For example, too much earwax is not good for our hearing and noise louder than 85 decibels(分贝) can hurt our ears and make us lose our hearing for a short time or even forever.
Hearing is a problem for all of us. So we should do our best to give our ears special care. Don't forget the following:
Try to stay away from places with too much noise. If you have to go, wear earplugs(耳塞). A pair of earplugs can cut the noise by 30 decibels. When swimming, remember to put earplugs into your ears to stop water from getting in. Never put anything sharp into your ears. If you think you have too much earwax, ask your parents to help you clean it out.
Keep these things in mind! Then you won’t ask “WHAT?” when you are older.

5 . Unless you’re very young or very old,it's likely you have some kind of relationship with email, whether you get hundreds of messages a day or a few dozen a week. A new study suggests that how we deal with these incoming messages could be affecting our stress levels and overall health.
A team from the Future Work Centre in the UK surveyed 2,000 people across various industries, sectors, and job roles, asking participants how they managed their email and how much associated stress they felt as a result. Overall, those who spent the most time organising and staying on top of messages felt the most email-related pressure too.
“While email can be a valuable communication tool, it’s clear that it’s a source of stress of frustration for many of us. The people who reported it being most useful to them also reported the highest levels of email pressure!” said one of the team, Richard MacKinnon.
Two of the habits linked to more email-related stress were checking for messages first thing in the morning and last thing at night. Half of those surveyed had push notifications (消 息推送）set up for new email, while 62 percent of respondents left their email app open all day and all night. Both were linked to higher levels of email pressure. The survey also found that managers suffered more than non-managers.
Stress is not just a problem when it comes to our mood—it’s been linked to a lot of disorders such as heart disease， weight gain， memory impairment (减弱），digestive problems,and depression.
The researchers suggest that the relationship between email-related stress and the negative impact on home life is not the same for everyone.
