【推荐1】For many people, back pain can make it difficult to function in everyday life. It affects how you move, feel and think, leaving you with no choice but to take some kind of action to relieve the pain. But instead of being reactive,     1    

Move more

Our bodies need adequate movement throughout the day to keep joints mobile and blood flowing through our muscles to avoid the inflexibility that contributes to aches and pains.     2    . If the weather is good, don’t hunt for the parking spot nearest to a store; don’t take the elevator when you have the option of one or two flights of stairs. When you need to sit for long periods, set a timer to get up every hour and be active for just a few minutes.

    3    

When we overuse our dominant side, we create muscle patterns of weakness and tension that increase pain and the likelihood of injury — especially in our backs. Consider the actions you take repeatedly throughout the day that shift your weight to one side: opening doors, carrying a bag, holding a leash to walk your dog, etc.

Correct imbalances

Just as you switch sides to balance out your body, you should also be aware of and correct imbalances in movements meant to be symmetrical (对称的).     4     Our bodies are designed to perform these activities in a balanced, alternating and interactive pattern.

If your back hurts at the end of the day, don’t just decide it was a “bad” day.     5    . Taking a proactive, daily-life approach to cultivating a healthy body is the key to keeping back pain at bay.

【推荐2】An Indian man recently shocked the airport staff in Abu Dhabi, because his passport showed he was born in 1896, which would make him 123, the oldest man to have ever lived.

Swami Sivananda’s passport shows him to be a year older than France’s Jeanne Louise Calment, who holds the Guinness World Record for the oldest person in history —122— but the problem is that the only evidence he has comes from an old temple register. Furthermore, he looks decades younger than his alleged age and has good health. He’s been trying to have his name included in the Guinness Book of Records for three years, but he has been having trouble proving his age.

Allegedly born on August 8, 1896, in Behala, then a village, Sivananda says he lost both his parents when he was only four, and his sister, who used to beg for food with him, two years later. His relatives handed him over to a guru (宗教教师), who brought him to the city of Nadadwip. Later, he settled in Varanasi. Sadly, there was no formal record of his age in these places and Swami Sivananda can only rely on a temple register to prove that he really is 123 years old.

“I lead a simple and regular life. I eat very simply — boiled food without oil, rice and boiled soup. I avoid taking milk or meat because I think these are fancy. In my childhood I slept many days on an empty stomach,” said Sivananda. “I believe in eating simply, living modestly and being merciful. I feel good when I have tried my best to help those in need.”

In other words, if someone is already ill or weak in some way, extreme heat can increase the risk of death.

Tony Wolf explained that the most worrying thing about extreme heat is how it affects the cardiovascular(心血管) system. The cardiovascular system helps regulate our body heat by redistributing(重新散发) heat between organs. An overheated person might find that their cardiovascular system is struggling to do that, which results in heat stroke(中暑), making the body unable to control its temperature.

The way that our bodies deal with heat starts with sweating. By sweating, the human body is able to maintain its regular temperature when facing extreme heat. But if a person isn’t sweating, they will lose plasma(血浆) and blood volume(血容量), causing the heart to work even harder. Wolf said this is why heat-related deaths are increasing. They’re “cardiovascular in nature” and often affect older populations or people with heart-related illnesses as they might have weak cardiovascular systems.

Previously, researchers thought the upper limit for the human body was 95 degrees Fahrenheit at 100% humidity(湿度), or 115 degrees Fahrenheit at 50% humidity. But Wolf and his colleague’s research has suggested that the upper limit could be 88 degrees Fahrenheit with 100% humidity, or 100 degrees Fahrenheit at 60% humidity. Wolf said he hopes this research can help drive some policy(政策) change as the world faces more frequent, serious heat waves.

【推荐1】Mobile phones have changed the way we communicate, but people disagree on whether the devices are useful tools for education.     1     Are they listening to the teacher or texting their friends?Are they taking a picture of a quiz to cheat? Maybe they are playing a game or watching a video instead of paying attention.

    2     For example , France passed a law banning the use of mobile phones in schools for students up to age 15 , the age when they go to high school.

Actually , students using their mobile phones in class have been a real problem. 'They are checking their phones, texting or going on social media.     3     Therefore, in order to solve the problem , the administration turn to technology for answers. Some schools now lock up mobile phones during the day in a special container.Each student must put his mobile phone away in a small bag with a magnetic（磁性的）lock.

More than 30 schools in France have put in place some kinds of restrictions during the current or last school year. Districts across the country also have their own versions of phone restrictions.

    4     The teachers in these schools believe that students have grown up with mobile phones.It's their responsibility to teach the students how to use the tools properly within the classroom.Besides , schools are teaching about mobile phones and how to use them with social media and the Internet.     5     In their eye, the technology has already existed , so schools should use it to help students and not fear it.

【推荐3】What is your dream job? If your answer is, “I can only have one?", you might be a slash youth(斜杠青年). The source of the term slash youth is the “/" used when introducing jobs in English. It refers to a group of people who no longer meet the lifestyle of a single occupation, but choose a diverse life with multiple occupations and identities. Those people are also called the slash-generation or slashers.

It is most likely a result of the ample amount of options students have today regarding their education. Since they are able to pick what they want to study, they prefer to continue doing this in their career path as well.

The number of people with slash careers in China has gone beyond 80 million. Many people think it is a trend. They note that multiple sidelines can make them acquire different skills. Xue Zhenni, 34, who has adopted a slash career, says, “My second identity as a tour guide has even promoted my first job——a human resources administrator. She adds that she could build up interpersonal communication skills and adaptability, and improve effectiveness. All of those gild (镀金) her first title.

Some people think if they limit themselves to a certain skill, they may risk going out of date in this changing society. The Chinese economy is transitioning (过渡) from high-speed growth to high-quality development. It requires a higher level of professionalism and more skills for young people in order to adapt to the changes.

Slashers' popularity has also raised concerns from critics, who argue that multiple roles risk weakening the performance of slashers in their full-time jobs. But most people agree with the idea that people can choose to be a slasher as long as their side work won’t affect their full-time one.
