Since smartphones were invented, more and more people have been addicted to them. The addiction to phones has spread to running. They’re perfectly used during a run outside. Smart phones can provide music for you and track your route. But experts warn that it’s not a good idea to hold your phone in your hand while you go out for a run because it could cause hip (臀部) and shoulder injuries.
Professional UK Athletics running coach, Alexa, asks runners to carry phones in a fanny pack (腰包) instead.“When you hold something in your hands, there are slightly indirect influences on your pace. It influences the balance of muscles (肌肉), affects the weight of some body parts, and makes you run less fast,” she tells Cosmopolitan UK.“This could be happening every time you train, week after week, month after month.” And as mobile phones get bigger and heavier, the more injuries are likely to happen.
People like to always hold their phones in the same hand. It’s a force of habit. With one arm heavier, your body will try to compensate for the imbalance, by working certain muscles harder than others.
The other risk of running with phones in hand, of course, is damaging the screen of your phones if you fall. It’s very expensive to change a screen. Some of the latest phones can close to $300.

If your children know the basic swimming skills, you can be at peace when your children are near the water. If you are in the process of teaching your children how to swim, then here are some points that you should keep in mind.
♦Help your children pick bathing suits. If your children want to wear a bathing suit and get wet then it is certain that your children will be able to handle the water.
♦If the pool has steps, then it is great. Start from these to help your children gain some confidence. You should make sure that there is one place in the pool where your children can be left safely.
♦The best way to teach your children to swim is to make them join swimming classes. In this way, you will be at peace because there is a professional trainer around your children who can teach them all the tricks of swimming.

【推荐3】When it comes to being fit and healthy, we’re often reminded to aim to walk 10,000 steps per day. This can annoy many, especially when we’re busy with work and other commitments—and yet where did this number actually come from?
The 10,000 steps a day target seems to have come about from a trade name pedometer sold in 1965 by Yamasa Clock in Japan. The device was called ”Manpo-kei“, which translates to ”10,000 steps meter“. This was a marketing tool for the device and has seemed to have stuck across the world as the daily step target. It’s even included in daily activity targets by popular smartwatches, such as Fitbit.
Research has since investigated the 10,000 steps a day target. But while some research has shown health benefits at 10,000 steps, recent research from Harvard Medical School has shown that, on average, around 4,400 steps a day is enough to significantly lower the risk of death in women. This was when compared to only walking around 2,700 steps daily. The more steps people walked, the lower their risk of dying was, before leveling off at around 7,500 steps a day. No additional benefits were seen with more steps. Although it’s uncertain whether similar results would be seen in men, it’s one example of how moving a little bit more daily can improve health and lower risk of death.
Recent research at the University of Texas has also demonstrated that if you’re walking fewer than 5,000 steps a day, your body is less able to metabolize(新陈代谢)fat the following day. A buildup of fat in the body can also increase a person’s likelihood of developing cardiovascular disease and diabetes. This is further supported by previous research which shows people who walked less than 4,000 steps a day could not change this decreased fat metabolism.
If you want to increase how many steps you get daily, or simply want to move more, one easy way includes walking to work if possible, or taking part of an online exercise program if you’re working from home. Meeting with friends for a walk—rather than in a cafe or pub—can also be useful.

| B．It is a rising tendency of mental health. |
| C．It is effective in reducing pressure on work. |

【推荐1】The problem with a catchy name is that sometimes it catches on too well. Take the hygiene hypothesis (卫生说) outlined in 1989 by David Strachan of St George’s, a hospital and medical school in London. It suggests that the rise of allergenic (致敏的) sensitivity observed in rich countries over the course of the 20th century may have been caused by a shift from rural to urban living, so that children are no longer routinely exposed to farm animals.
Dr Strachan’s work still has much to recommend it. What the catchy label has encouraged, however, is a false belief that cleanliness is not necessarily a health benefit. In reality, says Thomas Marrs, an allergist at King’s College, London, hygiene is usually about bacteria (细菌) causing infection—and the bacteria that may be beneficial are different from those which do that. But it is plain to see why alternative descriptions, such as “the high turnover and diversity hypothesis” or the “the microbial deprivation hypothesis (微生物剥夺假说)”, have not caught on, more accurate though they may be.
In an attempt to collect further data on the matter, Hisao Okabe of Fukushima Medical University and his team have looked through the Japan Environment and Children’s Study, which tracked over 100,000 births between 2019 and 2022.
Pursuing the animal connection, they looked for correlations between household pet ownership before and immediately after a child’s birth, and any food allergies found in that child’s first three years.
Of the 66,000 or so children they chose to look at, 22% had been born into households with pets. Children in households with dogs, the researchers found, had lower rates than average of allergies to eggs, milk and nuts. Those cohabiting with cats seemed more tolerant of eggs, wheat and beans. However, children whose parents kept turtles (龟) appeared unaffected. And, curiously, those exposed to hamsters (仓鼠) appeared more likely than average to be allergic to nuts.
Confirming or denying this will need more study. Nevertheless, Dr Okabe’s contribution is an interesting addition to the debate about Dr Strachan’s brainchild.

【推荐2】People have many different ways to relax during break time at work or school. Smartphones are probably the number one choice for a quick mental vacation. Although it might seem like a good time, the result is opposite, according to a recent psychological study from Rutgers University.
For the study, more than 400 students were asked to finish a set of 20 words puzzles. Halfway through the task, the students were divided into three groups. One group was allowed to take a break and use cellphones to buy things online. The second group was asked to have a rest and buy things using a computer. The last group didn’t take any break at all.
Surprisingly, the group that used their cellphones during the break went back to work feeling the most tired and least motivated to continue. They also had the hardest time solving the remaining word puzzles.
Terri Kurtzberg, co-author of the study, explained that they assumed looking at cellphones during a break would be no different from any other break — but instead, the phone may cause increasing levels of distraction that make it difficult to return focused attention to work tasks.
“Cellphones may have this effect because even just seeing your phone activates thoughts of checking messages, connecting with people, and more, in ways that are different from how we use other screens like computers, and laptops,” Kurtzberg said.
This is echoed by a recent study from the US University of Chicago. It found that even if cellphones are turned off or turned face down their mere presence has a bad effect on a person’s cognitive (认知的) function.

According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes（处理） information. It is similar to the way that exercise builds muscles(肌肉).
The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners. Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.“Our findings suggest that the structure（结构）of the brain is changed by the experience of learning a second language,” said the scientists.
It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),” he said. “You are actually going beyond language and have a better understanding of different ideas.”
The findings had the same result in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.

【推荐1】Language is always changing. In a society where life continues year after year with few changes, the language does not change, either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families.
1. The early language had ________.| A．a lot of problems | B．words and easy grammar |
| C．words but no grammar | D．grammar but not many words |

【推荐2】Nowadays robots are taking the world of sports by storm, from the six-legged skier to the ping pong ace and the expert curler.
Four-legged robot goalkeeper
Mini Cheetah, a four-legged robot, was trained up by scientists at the University of California, Berkeley’s Hybrid Robotics Lab.
The robot can handle a range of thrown and kicked shots from humans. It can squat, jump, sidestep and dive to stop shots. It can save 87.5 per cent of shots taken on goal, compared to the average for human keepers of around 69 per cent.
Google’s ping-pong arm
Google’s ping-pong robot arm recently completed an epic 340-shot rally (对打) with a human. The arm plays “cooperatively” to get a good rally going, but according to Google its skills could be built up to match the level of a serious human competitor.
Researchers wanted to train it up in a simulation so it could play with humans in the real world. China’s badminton bot
In China, researchers have created a robot called the Robomintoner that can play badminton against human competitors.
The machine looks a bit like a lawnmower (割草机), but it firmly grips its badminton racket just like any human player would. It also gets sufficient power into the shuttlecock using a swift flicking motion, and zips around the court on four wheels.
Expert skier
Also in China, experts from the Shanghai JiaoTong University created a skiing robot that can control its own descent down a snowy slope. The machine stands with two legs on each ski and grips ski poles with its middle legs, which it can manoeuvre (操纵) to control direction.
The robot can stay upright, turn and avoid crashing to people. It is also capable of skiing at more than 30 feet per second across a 1, 300-foot course on an 18-degree slope.

【推荐3】A letter to my children on their first day of school
Dear Olivia and Evan,
As I opened my eyes this morning, the realization that you will be starting a new school year at a new school today controlled my mind for a moment. As we went about our morning routine (例行事务), I thought of so many things I wanted to say to you.
As I quietly entered your room and softly kissed you awake—I wanted to tell you that I know what it’s like to be the new kid. I understand worrying about finding your way both physically and socially. You’ll spend a lifetime finding your way.
As I stood at the bathroom door while you brushed your teeth—I wanted to tell you to try not to look so nervous.
As we got in the car—I wanted to tell you not everyone will have things in common with you.
As I drove the few blocks to school—I wanted to tell you to listen when the teacher speaks, when someone new talks about themselves, etc.
As you got out of the car I gave you each a kiss and a hug and said — “Just be yourself, and remember how much I love you. I’ll be waiting to hear all about your experiences this afternoon.”
I realized that’s really all you needed to hear.
Love
