1 . Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:
Schedule yearly exams.
Protect against UV rays .
Long-term stay in the sun creates risk to your eyes. No matter what the season is, it’s extremely important to wear sunglasses.
Two-thirds of Americans spend up to seven hours a day using computers or other digital products.
As part of a healthy diet, eat more fruits and vegetables each day. Vitamins C and E help protect eyesight and promote eye health.
Practice safe wear and care of contact lenses.
Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk.
Otherwise: you may have problems such as red eyes, pain in the eyes, or a more serious condition.
| A．Eat your greens. |
| B．Eye care should begin early in life. |
| C．They can properly protect your eyes. |
| D．Stay in good shape by taking more vitamins. |
| E．Parents usually don’t care about their own eyesight. |
| F．Always follow the doctor’s advice for appropriate wear. |
| G．This frequent eye activity increases the risk for eye tiredness. |
2 . How tall are you? Do you tower over your friends and family - or are they people you literally have to look up to?
Of course, our height is out of our control.
In a recent study scientists have discovered a brain receptor, called MC3R, linked to our growing process.
For those eager to be taller, we need to look at the Dutch, who stand head and shoulders above the rest of us as the tallest people in the world. But, of course tall people have to stoop (俯身) through doorways and struggle to fit in cars and can have joint and cardiovascular problems.
| A．Are you getting as tall as you want to be? |
| B．It’s a biological fact influenced partly by genetics. |
| C．So maybe we should be careful for what we wish for. |
| D．Obviously, we’re not all the same, and size doesn’t really matter. |
| E．It’s thought to be the crucial link between food and sex development and growth. |
| F．There is a ceiling for height, and it’s reached when people achieve their genetic potential. |
| G．If this makes you want to be taller, it’s good to know we are taller than we were 150 years ago. |

4 . 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.

5 . 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. |
6 . Much information can be conveyed, purely through our eyes, so the expression “eyes also talk” is often heard.
Can you recall any experience that further proves this statement? On a bus you may quickly glance at a stranger, but not make eye contact. If he senses that he is being stared at, he may feel uncomfortable.
It is the same in daily life. If you are stared at for more than necessary, you will look at yourself up and down to see if there is anything wrong with you. If nothing goes wrong, you will feel angry about other's staring at you that way. Eyes do convey information, right？
Looking too long at someone may seem to be rude and aggressive. But things are different when it comes to staring at the opposite sex. If a man looks at a woman for more than 10 seconds and refuses to turn away his gaze, his intentions are obvious. That is, he wishes to attract her attention, to make her understand that he is showing affection for her.
However, the normal eye contact for two people engaged in conversation is that the speaker will only look at the listener from time to time, in order to make sure that the listener does pay attention to what the former is speaking, to tell him that he is attentive.
If a speaker looks at you continuously when speaking, as if he tries to control you, you will feel uneasy. A poor liar usually exposes himself by looking too long at the victim, since he believes the false idea that to look straight in the eye is a sign of honest communication.
In fact, continuous eye contact happens between lovers only, who will enjoy looking at each other tenderly for a long time, to show love that words cannot express.
Evidently, eye contact should be done according to the relationship between two people and the specific situation.

7 . As doctors performed surgery on Dagmar Turner’s brain, the sound of a violin filled the operating room. The music came from the patient on the operating table. In a video from the surgery, the violinist was moving her bow (琴弓) up and down as surgeons worked to remove her brain tumor (肿瘤). The King’s College hospital surgeons woke her up in the middle of the operation in order to ensure they did not damage parts of the brain necessary for playing the violin and keep her hand’s functions intact.
Turner, 53, learned that she had a slow-growing tumor. Later doctors found that it had become more aggressive and the violinist decided to have surgery to remove it. “We knew how important the violin is to Turner, so it was vital that we preserved function in the delicate areas of her brain that allowed her to play,” Keyoumars Ashkan, a doctor at King’s College Hospital, said in a press release.
Before Turner’s operation, Ashkan and his colleagues spent two hours carefully mapping her brain to identify areas that were active when she played the violin and those controlling language and movement. Waking her up during surgery then allowed doctors to monitor whether those parts were suffering damage.
Brad Mahon, expert at Carnegie Mellon University, said the basic features of an “awake craniotomy” — the type of brain surgery where patients are awake in order to avoid damage to critical brain areas — have remained largely unchanged for decades. But he said that doctors are now able to map the patient’s brain activity in great detail before the surgery, using an imaging technique called functional MRI. That means surgeons are coming into the operating room with far more information about a specific patient’s brain. That kind of information helps doctors tailor tests to a patient’s particular needs.

8 . Take care of your spine（脊柱）
The spine stands at the center of your health, providing your body with structure and support. It also contains your spine cord, a massive collection of nerves conveying electric signals from the rest of your body to your brain
Maintaining good posture( 姿势) is one of the most important things you can do to keep your spine healthy. Proper posture means standing or sitting while keeping your spine straight, except for its natural curves. Posture comes into play even when you are asleep. Sleeping on your side puts less stress on your spine than most other positions.
Finally, your diet affects the health of your spine because many vitamins are necessary for bones and nerves. In particular, vitamins B and D are essential to keep bones healthy, so you may want to consider taking a supplement.
Many of the actions necessary to keep your spine healthy are identical to those used to preserve your health in other ways.
| A．However, the latter is also absorbed from sunlight. |
| B．Staying still for too long can be hard on your back. |
| C．So protect your back, the rest of the body will benefit. |
| D．Protecting your spine with yoga is also a necessary step. |
| E．Try the following exercises to keep your spine more flexible. |
| F．Exercise is also an important factor in the health of your spine. |
| G．So you should take the following factors into account to have a healthy spine. |

10 . Be at your best!
What does your brain need to work well? Here are some things it needs.
Good food
Experts say that breakfast is much more important than any other meal.
A regular supply of energy
Your brain needs a regular supply of energy, so you need to eat carbohydrates (碳水化合物). They’re found in bread, rice, pasta and beans.
A continuous supply of oxygen (氧气)
Your brain needs oxygen, which it gets from exercise.
Water
Your brain needs several hours’ sleep, so it can ‘update’ itself, just like a computer. Experts say that when you study for a test or an exam, you should get some sleep as quickly as possible after you’ve finished studying. This helps you to remember what you’ve learned.
| A．A short break |
| B．A good night’s sleep |
| C．It works best in the morning. |
| D．Exercise improves your memory too. |
| E．Water is much better than sweet drinks. |
| F．Your brain works better when you have eaten. |
| G．Chocolate, biscuits and sweets are not good for your brain. |
