If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.

Hair loss can be due to a variety of factors, including a genetic tendency (which is not genetically linked to just one parent—both parents contribute to the tendency to lose hair).
Women who are experiencing hair problems seem to have more limited choices than men. There are some female hair loss treatments that are available such as the Tricomin System which is a topical treatment that is nutrition based. Shen Min for Women is another natural treatment that contains herbs (药草) that are said to stimulate(刺激) hair growth and even restore hair that is graying to its natural color.
The majority of the popular, prove hair loss treatments are only intended for men and are not suitable for women. True, a woman’s hair issue is different from a man’s. The biological makeup is different and the needs are different. Women have different needs and their bodies react in different ways to environmental changes, physical illness and even the treatments that are available. There are many natural treatments such as vitamin and mineral supplements that are said to stimulate hair growth, but, for the most part, these claims are currently unproven.
One of the first and most important factors to effectively treating is to get a diagnosis from a doctor. Talk to your doctor about any symptoms(症状) that you may be experiencing in addition to the thinning hair. Stress, weight loss or gain, illness and depression, all of these can be contributing factors.

【推荐3】Crossing your legs is an extremely common habit; most people don’t even notice that they’re doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won’t feel any immediate effects, but if you sit for long periods of time it’s important that you take note of how long you have your legs crossed for. You shouldn’t have your legs crossed for more than 15 minutes, and it’s important that you get up and walk around at least once every hour.
Crossing your legs can also lead to neck and back pain. Ideally, it’s best for our bodies to sit with our feet planted flat, hip width apart, on the floor, but it’s not easy to maintain perfect posture all day at the office.
You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get tingly(刺痛的) or have the feeling of being asleep. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

【推荐1】Every year, thousands of people gather in Spain’s northeastern city of Pamplona for the opportunity to run for their lives as six fighting bulls are set free to charge through the town.
But the event is of interest not just to adventurous tourists. Daniel Parisi and his team realized that the Pamplona bull runs offered a perfect natural experiment to study the activities of frightened crowds.
That is a useful topic to explore. Architects, civil engineers and urban planners must try to work out how people will behave in the event of a disaster so they can design their creations to avoid potentially deadly crushes. Unfortunately, reliable information is hard to come by. Authorities, after all, are likely to frown on researchers putting volunteers into serious danger simply to study how they might behave.
In July 2022, the researchers set up two cameras on the rooftops and recorded the runners’ behaviors as the animals were charging through the town. Then they brought their recordings back to the lab to calculate the speeds of the runners, the density of the crowd and the probability of a runner tripping and falling. Perhaps unsurprisingly, the researchers found that runners picked up speed when the bulls drew near. Less expected was the finding that the speed of individual runners increased with the density of the crowd. At the crowd’s maximum speed of around four metres per second, density reached roughly one runner per square metre. This finding is contrary to a long-held assumption that people will slow their pace as group density goes up. Their data further suggests that, in the heat of the moment, people pay little attention to the danger of running into each other, and do not slow down.
Their conclusion? The only option for the urban designers is to plan wider stairs, tunnels, bridges and other passages in the future.

【推荐2】La Casa en el Aire (literally “The House in the Air” in Spanish) is a unique hostel located on a cliff face, about 30 meters above the ground, in the Colombian mountains.
Built primarily out of wood and featuring a tin roof, the cheap hotel is attached to a bridge that rises up among the area. It is held in place by several steel wires connected to the cliff and supported by a long wooden pole also placed against the cliff. It stands about 20 meters above the ground, at an altitude of about 2,500 meters above sea level.
La Casa en el Aire is the brainchild of Colombian mountain climber Nilton Lopez, who recently said that building this unusual hostel meant realizing an old dream of his. He is most proud of the fact that his creation is practical, with electricity being produced by solar panels, and all rubbish being collected and transported to Medellin.
Apart from staying and sleeping in a cabin hung on the side of a huge rock, visitors of La Casa en el Aire can also involve in a variety of exciting activities, such as bungee jumping out of the house or spending the night in hammocks(吊床)hung on steel wires above the house.
Because the hostel is located in a faraway area of Abejorral, with no easy access to food and water, visitors are encouraged to bring long-lasting foods (dry bread, cookies, etc.), as well as five-liter bottle of water with them.

【推荐3】We’ve all been there, running for a ls or train on a cold morning only to find that our nose is also running! Grab some tissues and learn the science behind the phenomenon known as “skier’s nose.”
A nose like a running tap in winter is business as usual for many people. People call it “skier’s nose". In a study, researchers found that 96 percent of people surveyed reported experiencing some degree of the condition.
Apparently, getting a runny nose in cold weather is a bodily defense reaction. That' s because the nose has two main purposes: 1) to filter bacteria so they don’t reach our lungs, and 2)to warm and humidify(加湿) the air before it reaches our lungs. Our airways are lined with tiny hairs known as cilia In the nose, these cilia wave back and forth to remove our mucus (黏液)so that bacteria can be blocked out. In cold weather the cilia are slowed. When cilia slow, bacteria remain in place and multiply, and this is why people get sick in winter. Not that the nose isn't trying to keep you healthy. All that running nose experience is the nose working overtime to produce more liquid to help move bacteria along. To help it out, experts say that you can try physically warming your nose: Rub your hands together, and then breathe into cupped hands or draw in steam from hot green tea and drink it, as green tea helps accelerate the growth and functioning of cilia.
Our nose runs in winter for one more purpose, which is to fight against the drier outside (and inside) air. In winter, or when it’s cold outside, the air is much drier than in summer. Our noses respond by producing more liquid to help humidify the air to a level our bodies need, and that’s when it starts to run out of the end of our nose.
1. What does the underlined word “filter” probably mean in the third paragraph?| A．Kill. | B．Prevent. |
| C．Defend. | D．Trap. |
| A．They only exist in the nose. | B．They stop working in winter. |
| C．They can sweep away mucus. | D．They help break down bacteria. |
