You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belvaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created Lampbrella, a lamp post with its own rain sensing umbrella.

    The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp,” he said.

    The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)then ensure that the umbrella offers pedestrians(行人) shelter whenever it starts raining.

    In addition to the rain sensor, there's also a 360° motion sensor on the fiberglass street lamp which detects whether anyone's using the Lampbrella. After three minutes of not being used, the canopy is closed.

    According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded(埋地线) to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being installed(安装) at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

    While there are no plans to take the Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

    While sweet treats can be hard to resist, the World Health Organization(WHO) has set new guidelines for people around the world. The guidelines, released on Wednesday, advise that both adults and children cut back on their sugar intake(摄取量) to stay healthy.

    In a statement, Francesco Branca, director of the WHO's nutrition department, said there is evidence that reducing daily sugar intake reduces the risk of being overweight and tooth decay(腐烂).

    The guidelines do not apply to the sugars in fresh fruit and vegetables or those that are naturally present in milk. According to the WHO, there is no reported evidence of negative effects of consuming those sugars. Instead, the new guidelines focus on “added” or “free” sugars. These include sugars that are added to processed foods and drinks such as candy and soft drinks.

    Added sugars are sometimes described as “ hidden” sugars because they exist in foods we might not think of as sweets, such as honey and ketchup(番茄酱). Health experts advise that consumers look at ingredients on food packages to help make better-informed decisions.

    The WHO recommends that people in the United States, Europe and other Western societies should cut their average sugar intake by about two-thirds, or down to just 10% of their overall calories. For developing countries, where dental care is less advanced, the WHO recommends that sugar intake be reduced to 5%.

    Scientist Kieran Clarke, of the University of Oxford, notes that for those people who can't shake their love for sweets, getting more exercise is a good solution. “If you get enough exercise, you can eat almost anything,” she said “But it's very hard to avoid large amounts of sugar unless all you're eating is fruit and vegetables.”

    Billionaire Bill Gates has offered the many thousands of graduates some career and life advice. Over a series of 14 tweets in his Tweeter posted last Monday, the world's richest man used the words “impact”, “happiness” and “progress”. He did not mention money. Instead, he told the graduates what jobs he would be looking for if he started out today.

“AI (artificial intelligence), energy and bio-sciences are promising fields where you can make a huge influence”, he wrote. Earlier this year, Gates—who famously dropped out of Harvard to found Microsoft—said that artificial intelligence had “ phenomenal” potential, and “anything connected with that would be an exciting lifetime career.” In the same speech at Columbia University, he said there is a huge growing demand in the energy field to develop reliable, cheap and clean energy.

    As well as urging new graduates to surround themselves with people who challenge you, teach you, and push you to be your best self, Gates reminded them to think of others, especially the less fortunate.

    He wrote that it had taken him decades to learn about the world's worst unfairness and described this lack of early understanding as his one big regret. “You know more than I did when I was your age,” he wrote, “ You can start fighting unfairness, whether down the street or around the world sooner.”

    He finished by asking graduates to consider the progress human has already made, saying that he believe the world is getting better. “ That matters because if you think the world is getting better, you want to spread the progress to more people and places.”

    Relieving poverty has been one of our government's top concerns for the past decades. Poverty(贫困) in remote areas in China is virtually a great obstacle for the Chinese to get common progress; thus, it is urgent for us to help the people there to shake off poverty the sooner the better. For this aim, the government has already sent technicians and experts to poverty-stricken areas to help boost local agricultural production and teach the locals new techniques. The Ministry of Labor has also trained many rural laborers through different programs. But all these are not enough. Several other ways have been proposed as follows.

    First of all, the government should encourage a small part of the people in the remote areas to get wealthy ahead of others by equipping them with relevant funds and agricultural technology. These “better-offs” can not only set a good example but give confidence to the poorer in their efforts to get rid of poverty. When all the people get rich, the general level of living standard can be greatly improved. With their living standard improved, they can attach greater importance to environmental protection and are willing to input considerable amount of money to educate their children. Only in this way is a sustainable development guaranteed.

Secondly, we must call upon people in all walks of life throughout the country, especially those wealthy citizens in coastal areas to help those struggling below poverty line in poor remote regions out. We must realize that only after all Chinese people live a comfortable life can we be peacefully enjoying material prosperity in life. Helps can come in various forms—-donating money to the poor family and books to school drop-outs, college graduates volunteering to work in the most needed regions, bringing knowledge to them, etc.

    The last but not the least, the government should raise the rate of tax on the rich. This can shorten the gap between the poor and the rich as well as benefit the country's revenues(财政收入) whose better part is in turn allocated to the poor remote areas.

    Admittedly, it is never easy to cast off the shadow of poverty in the remote areas completely in the short run. But every one of us should go all out to help those in poverty, we are confident that our country will be more powerful and prosperous in the process of relieving poverty.

    The saying, "Don't judge a book by its cover, means you should not guess the worth or value of something based on how it looks. That message was clear at a recent event called the Human Library Project. The event took place at the Northern Virginia, or NoVa, Community College, outside of Washington. D. C.

    The Human Library began 19 years ago in Denmark. It grew from a youth organization called "Stop the Violence". Today, it is a worldwide movement. At the NoVa event, students got the chance to learn from a person—a "human book"—instead of a library book.

    Patricia Cooper organized the event. She said that human books celebrate variety by telling their life stories in an easy-going setting. "The goal of the human library is to talk to people in your community who you may otherwise not speak to because you have your own prejudices (偏见) and hopefully to break down some of these barriers."

    This is the third year that NoVa has held such an event. The collection of human books included a civil rights activist, a scientist from the American space agency NASA, and an opera singer.

    Artist Brian Dailey was a human book. He spoke about his travels to 113 countries in seven years. Dailey said that, during his travels, he asked people whom he took pictures of for a one-word answer to a series of other words—such as love, freedom and war. He discovered that people in different countries often had very different reactions to the same word.

    When Dailey asked people in Africa about the word "war" they used words like justice, liberation and peace. When he asked the same question to people in Syrian refugee camps, the answer was: "tears, hunger, fear, destruction".

Throughout human history, there is a bottomless well of people who made great contributions so that we can now enjoy a better life. The following are, just four of those great minds.

Joseph Lister(1827—1912)

English surgeon(外科医生) Lister pioneered the use of antiseptic(防腐的)and antiseptic surgery which greatly improved survival rates from major surgery. For this, he is often referred to as the father of modern surgery as his use of antiseptic greatly increased the kinds of operations that could be carried out.

Maximilian Bircher-Benner(1867—1939)

Bircher-Benner was a pioneering Swiss physician and nutritionist. He advocated the eating of raw fruit and vegetables and discouraged eating meat and heavily processed foods. Although he was questioned by the scientific establishment, his healthy eating ideas took off and helped create a diet of processed bread, meat and carbs (碳水化合物). The healthy eating trends he established have continued to grow in popularity with more scientific research showing the health benefits of such a diet.

Paracelsus(1493—1541)

Swiss-German physician and leading health reformer. Paracelsus founded the discipline of toxicology(毒理学)and pioneered the use of chemicals in treating patients. He emphasized practical experience. He was also one of the first doctors to note illness can be psychological in nature.

Peter Mansfield(1933—2017)

English physicist who with Peter Lauterbur helped to develop magnetic resonance imaging(MRI)which gets doctors to see inside a patient's body without needing to cut it open. With MRI, doctors can see far more than with x-ray, which is limited to bones. He was awarded the Nobel Prize in Medicine in 2003.
