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.

| 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 . 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.

3 . If you don't use it, you lose it. At least, that's how the old saying goes. It refers to the idea that something which does not get used regularly quickly falls into a state of decline. Muscles, for example, will waste away without use. In order to resist this, people take regular exercise to keep their skills sharp.
Well, what about the brain? As we age, our brains can naturally begin to decline. In some cases, this can lead to certain mental conditions such as dementia(痴呆)，which I'm sure you will agree, no one wants. However, all is not lost because these days it's relatively easy to train your brain. Smart phones and apps have put programmes into our hands that can test, maintain and even improve our memories, mathematical skills and a lot of other mental abilities. With a little practice every day, we can keep our brains nice and sharp, right?
Well, no, actually. According to a report from the Global Council on Brain Health, even though many people thought it was important to play online games, such as puzzles and mind games, which are designed to improve brain health, the evidence of the benefits was “weak to non-existent”.
There are other ways to promote the old grey matter. It recommends seeking out new activities that challenge the way you think and are socially engaging，while leading to a healthy lifestyle. Among their suggestions are practising tai chi, taking photography classes, learning new technologies, gardening, art projects or volunteering.
There's more good news, too, James Goodwin, chief scientist at Age UK has said that brain decline is not inevitable (不可避免的）. As long as the activities are “new to you and require your concentrated attention”, they can provide benefits for brain health. So, hurry up, get out there and try something new. Maybe it's time to try that hobby you've always wanted to do. And as for me? I'm off to learn the piano.

7 . Feifei, an 11-year-old boy from Xuzhou, Jiangsu Province, suffered from a sudden acute eye disease which has almost led to blindness. The disease was caused by excessive(过度的)eye fatigue(疲劳)during the winter vacation, during which he played computer games for continuous 10 days and nights.
Many youngsters in China nowadays are increasingly addicted to computer games and other electronic products. This is followed by a series of health problems, with the most typical case being myopia, or nearsightedness.
According to the latest research report released by the World Health Organization (WHO), the myopia rate among Chinese teenagers ranks first in the world—70 percent of high school and college students. The rate is nearly 40 percent in primary school students, while it is only 10 percent for their peers in the United States.
There are at least 10 million people in China with severe myopia, and they are likely to get pathological(病理性的)myopia in middle age. Pathological myopia can't be treated with glasses or surgery, and it is one of the biggest factors that lead to blindness, Xu Xun, director of the ophthalmology(眼科学) department at Shanghai General Hospital, pointed out.
Experts explain that two major factors lead to the high rate of myopia among Chinese people. One is high academic pressure, and the other one is excessive use of electronic devices over a long period of time. Genetics, on the other hand, are not the main reason, as only 20 percent of Chinese people had myopia in the 1960s.
"Teenagers are now faced with severe academic pressure, which means they often study without natural light. This increases their risk of becoming nearsighted," Xu said.
Experts suggest that youngsters maintain a proper balance between study and rest so as to protect their eyesight, and parents should play an active role in the process.

8 . The way you stand can identify whether you will suffer from aches and pains in the back or neck in later life, the British Chiropractic Association has said. Whether you are a “spoon”, “bridge”, “leaning tower” or “flat-back” will determine your risk of having problems later.
A quarter of women suffer pain lasting between one and three days starting at the relatively young age of 34, the survey found. While previous indicators have focused on body shapes, with larger-breasted women and “apple” shapes being seen as a warning sign, this new research shows posture (姿势) could be key in preventing back pain.
“Leaning tower” —women whose heads lean forward — are most likely to report pain, with almost six in ten with this posture already suffering. Being a “bridge” with an arched back was the second worse posture, followed by a “spoon” position with rounded shoulders but a flat back. And a change in posture can be far less demanding than a crash diet or an exercise programme.
“Flat back” ladies, who keep their backs flat are the most likely to avoid pain with a fifth reporting they have never suffered back or neck aches in their lives. Tim Hutchful, a member of the British Chiropractic Association said, “Rather than worrying about being an ‘apple’ or an ‘hourglass’ , we want people to think about what they look like from the side. The perfect posture should give you a side-on appearance with your ears, shoulders, hips, knees and ankles in line. ” People who want to improve their back and neck pain symptoms through a better posture should try imagining they have a plumb line (铅垂线) hanging straight from their ears to ankles —with everything in the middle sitting on the same line. One way to do this is to try standing in a relaxed way and then gently pressing together the abdominal muscles (腹肌).

9 . Easy Ways to Keep Your Brain Sharp
Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit- -and that can be a very annoying thing.
1.
People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer’s disease (早老性痴呆症)，according to a recent study.
2. Go for a walk.
Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain.
3. Learn something new.
Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time.
| A．Focus on the future. |
| B．This can be especially harmful to the aged. |
| C．It should be something like learning gardening. |
| D．So take a few minutes each day to do some reading. |
| E．But don’t worry if your schedule isn’t filled with life changing events. |
| F．Luckily, research shows there is a lot you can do to avoid those moments |
| G．In other words, when you take care of your body, you take care of your brain. |
