    Experts say there are about 6, 500 languages spoken throughout the world. But the United Nations estimates that about half of these languages are in danger of disappearing.

    One non-profit organization seeking to save world languages is a New York-based group called Wikitongues. Officials from Wikitongues say the organization has a simple goal: to provide the tools and support that people need to save their languages.

    Udell is the co-founder of Wikitongues. He said when a language disappears, many other things can go away as well. For example, parts of a community's culture, knowledge and identity can also be lost. Because of this. Udell believes the process of bringing languages back must be done by community members themselves, “from the ground up,” he said.

    “There is no way an outside organization can save someone's language for them.”

    Wikitongues was launched in 2016 as an open internet collection of world languages. The self-described “community” is operated by volunteers from around the world. The collection is in the form of language videos that people add to the Wikitongues website.

    There are currently more than 400 languages and dialects represented on Wikitongues' YouTube channel. Udell says more than 1,500 people from 70 different countries have added videos to the system.

    “We have people from India who record dozens of languages, which is beyond their own.” he said.

    One of Wikitongues'volunteers is Kolokwe, who lives in Namibia. His native language is Subiya, however, he does not get the chance to speak his native language every day. Like many other educated people from his area, he speaks a lot of English and Afrikaans.

    Kolokwe is hoping his involvement with Wikitongues call help keep Subiya and other African languages from going extinct. He wants the world to know about his language. But his goal goes beyond just sharing his language with others through video. He is also working to create a dictionary and language teaching materials that can be used in schools.

Is Fresh Air Really Good for You?

    We all grew up hearing people tell us to "go out and get some fresh air." {#blank#}1{#/blank#} According to recent studies, the answer is a big YES, if the air quality in your camping area is good.

    {#blank#}2{#/blank#} If the air you're breathing is clean-which it would be if you're away from the smog of cities-then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉)and your brain.

    Recently, people have begun studying the connection between the natural world and healing(治愈). {#blank#}3{#/blank#} In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood(情绪).Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. {#blank#}4{#/blank#} It gives us a great feeling of peace.

    {#blank#}5{#/blank#}While the sun's rays can age and harm our skin, they also give is beneficial Vitamin D. To make sure you get enough Vitamin D—but still protect your skin— put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that's plenty of time for your skin to absorb a day's worth of Vitamin D.

A. Fresh air cleans our lungs.

B. So what are you waiting for?

C. Being in nature refreshes us.

D. Another side benefit of getting fresh air is sunlight.

E. But is fresh air really as good for you as your mother always said?

F. Just as importantly, we tend to associate air with health care.

G. All across the country, recovery centers have begun building Healing Gardens.

    It is a question people have been asking for ages—is there a way to turn back the aging process?

    For centuries, people have been looking for a "fountain of youth." The idea is that if you find a magical fountain, and drink from its waters, you will not become old. Spanish explorer Juan Ponce de León searched for waters with magical powers in the early 1500s. But what he found instead is the American State of Florida.

    Researchers in New York did not find a fountain of youth in fact, but they may have found a way to turn back the aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus (丘脑下部).The hypothalamus is part of your brain. It controls important activities within the body, including growth, reproduction and the way we process food.

    Researchers at New York's Albert Einstein College of Medicine found that hypothalamus stem cells also influence how fast aging takes place in the body. What are stem cells? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged parts in the body.

    Professor Dongsheng Cai was the lead researcher in a study on aging in mice. Cai explains in the Journal Nature what they found. "Aging speed can be controlled by a particular place in the body, which is the hypothalamus. And it can be controlled by a particular type of cells, which are hypothalamus stem cells. I think these findings are quite interesting."

    He adds that when the hypothalamus starts aging, so does the body. "So when hypothalamus function is decreasing, particularly the loss of hypothalamus stem cells, this protection against the aging development is lost. It finally leads to aging."

    Using this information, the researchers began trying to activate (激活) the hypothalamus in mice. They did this by putting stem cells from younger mice into middle-aged animals. Later, the researchers examined mice and tested for changes in behavior. They also looked for changes in the strength of the animals' muscles and the way they worked. The researchers say the results show that the treatment slowed aging in the animals.

    Cai says when hypothalamus stem cells, which were derived from young mice was put into middle-aged mice, the mice aged slowly and they also have increased the length of their lives.

    But these results were just from studying mice in a lab. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings.

    Doctors say you had better use it before you lose it. The more you sit each day, the more chance you have of getting sick.

    Richard Rosenkranz of Kansas State University was among the researchers. He said people who sat for long periods were at great risk of diseases when compared with those who sat less. He said that was especially true for some chronic (慢性的) diseases.

    Richard Rosenkranz studied the relationship between sitting and chronic diseases in middle-aged Australian men. He worked with researchers from the University of Western Sydney. They examined the health records of more than 63,000 men from New South Wales. The men were between the ages of 45 and 65. The men reported about what diseases they had, or did not have. And they kept record of the amount of time each day that they sat.

    The study also showed that exercising every morning for 30minutes did not reduce the health risk if you spend the next eight hours sitting at the desk. Mr. Rosenkranz said it was important to make sure you exercise. But he said it was also important to find ways not to sit so much during the day.

    Many jobs today require sitting and working at the desk all day. James Levine works at the Mayo Clinic in the United Sates. He suggests working while standing at high table some of the time instead of sitting at a desk. Dr. Levine also suggests standing while using the telephone or eating. Or he advises walking with the people you work with for an on-foot meeting. And he notes that if you spend more time on your feet, you may have muscle activity that helps burn fats and sugars in your body.

Poetry{#blank#}1{#/blank#} (communicate) in words. To do that{#blank#}2{#/blank#} (successful), it must have something important to say, expressing it in a unique way. Whether you are writing poetry yourself or analysing (分析) poems {#blank#}3{#/blank#} (write) by someone else, you should be thinking about these two broad categories: what is being said, and how it is being expressed.
