Fitness trackers are designed to record your physical activity. They are usually worn around the wrist, where they measure a person's heart rate. Many people wear them in the hope of losing weight. But a new study finds the electronic device probably does not help with weight loss, according to the researchers from the University of Pittsburgh in the US.

    The University of Pittsburgh research team watched two groups of individuals. The first group wore a fitness tracker and took part in health counseling. The researchers compared this group with people who only took part in health counseling. The study found that those who simply had health counseling lost more weight than those who had counseling and wore a fitness tracker. In fact, those who only spoke with the health experts lost nearly six kilograms. Those who used a fitness tracker lost only three and a half kilograms.

    John Jakicic is the lead researcher. He is also chairman of the university's Department of Health and Physical Activity. He questioned the use of electronic devices as tools for weight control and conducted a study which involved 470 people between the ages of 18 and 35. Some of them were overweight, while others were heavier and considered obese. Over three fourths of the people were women. All people were told to have their weight measured once every six months over the two-year study. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a wearable fitness tracker. Eighteen months later, both groups showed significant improvements in body fitness. However, when it came to losing weight, the people who only spoke with the health experts lost nearly twice as much weight.

    As an athlete, Kylie Graves has turned many teammates into friends. She knows how fortunate she is, but also recognizes some of her peers aren't as fortunate. As the leader of a defense at sweeper(自由中卫), kylie possesses strength as well as good leadership ability, and a drive to win.

    Kylie and her sister Emily founded a Best Buddies chapter to help build one-to-one friendships between students with and without intellectual and developmental disabilities. These relationships help erase( 消除 )the invisible line that often separates students with such disabilities.

    The sisters were inspired by their brother Braden, Emily's twin brother, who has Down syndrome(唐氏综合征) but doesn't, tallow it to prevent him from being involved in athletics and activities at school. He serves as the manager for the girls basketball and girls soccer teams.

    "We realized that Braden's fully involved in teams at school, but other kids aren't getting that same experience," Kylie said. "With Best Buddies we're able to get more kids involved, to go to school events and to meet more people. "Off the field, Kylie hopes to become a neuroscientist who helps improve the lives of those with Down syndrome and other disabilities.

    "I've spent the most time in soccer so it's my favorite, "she said." I have to make sure it doesn't get to the goalie(守门员), so I' m responsible for backing everybody up. I like that role and I talk a lot on the field.”

    While she might be in back, she's at the forefront of motivating her teammates. As a freshman, Kylie expected to be a midfielder, but her coach desperately needed a sweeper. "I trained her a bit, "her coach said." She always puts the team first. We knew she could be successful in this role.

    "I've been in those situations so many times that it doesn't bother me anymore, "Kylie said. It's my job to stay calm and keep my teammates calm. I kind of feel like I'm doing my job like I'm supposed to do."

    You can often see a square dance team swing with the music in China.

Square dancing in open squares or other public areas is one of the favourite sports to kill time "Chinese Dama," who usually enjoy it in the evening, or sometimes much later until the night ? The aged dancers usually have at least two things in common: almost none of them is well under the age of 45, and in most cases the music they dance to could be extremely loud. They are called the Dancing Dama, and their hobby called guangchangwu can be literally translated as the "Public Square Dancing".

    When the Chinese Dancing Damas danced in New York City, some of them danced since early hours, making great noise. Some of the public couldn't stand such loud noise and were completely against the performance. They even called the police to restrain( 阻止)them.

    On average, other countries have a more positive attitude than the United States. For example, in the capital of Romania-Bucharest, a group which is called" Red Dragon" would start dancing every evening at 6: 30 in the north-east suburb of the city. They not only brought joy to the surrounding area, but also attracted numerous natives to engage in the dancing.

    Chinese square dancing is considered difficult to survive outside China. "Dancing in the square" should be appreciated as an element of contemporary Chinese culture rather than an independent culture.

G. Such dancing, though not against any laws or regulations, can disturb the public serenity (宁静)

    Who will you ask for help when you want to learn something? A friend? A tutor? These are all 1ways of learning. But it may well be that the learning you really want2 somewhere else, I had the3 of seeing this first-hand on a4.

    My daughter played on a recreational football team. Her team did very well this season and so 5a tournament, which normally was only for more skilled club teams.
