As you focus on your breathing and movements, your mind can clear itself of its worries,     3     does your whole body good,

    4     (influence) by Taoist and Confucian thoughts, and the ideas of traditional Chinese medicine, the practice has developed into several styles,     5     (usual) named after a master, such as Chen-style and Yang-style.

Chen Bin, one of the     6     (master) of the Chen-style tai chi, has been practising the martial art since he     7     (be) six years old. More than two decades of practice has made him a master. “One’s understanding of tai chi can develop when the practice continues. As one’s experience grows, it becomes much     8     (easy) to understand its cultural meaning,” Chen Bing explains.

Tai chi has taught Chen Bing     9     (stay) calm during life’s ups and downs, and to learn about the world with     10     open mind. Moreover, the martial art encourages using gentleness to get over toughness, and making use of weakness to win strength through one’s self-awareness, which shows the wisdom of Taoism.

Plogging     1     (refer) to the act of picking up trash while jogging. Ploggers collect trash, such as plastic bottles, waste paper and cans from parks, beaches, and other outdoor areas when they exercise.

The     2     (found) of plogging was Erik Ahlstrom. He used to live in a small town, but later he moved to Stockholm,     3     capital city of Sweden. He could hardly believe     4     he saw there—garbage filled every corner of the city. So, he decided to do something     5     (change) the situation. Every time he went jogging, he would invite some friends to pick up trash with him. This gradually became a habit and inspired more and more people to join in the activity. Some famous sports brands even began to provide     6     (run) shoes for plogging enthusiasts (爱好者). Since then, plogging     7     (become) increasingly popular around the world.

Now, plogging is widely recognized as an     8     (effect) and eco-friendly way to keep healthy and contribute to the environment. Whether you are a fitness enthusiast     9     simply want to do your part to protect the environment, plogging will be a great choice. So, why not give it a try? You might find a new way to stay connected to nature and make the Earth a     10     (good) place to live on.

We all know that video games can get pretty     1    (addict) and, like everything in life, sometimes people go too far. Here is     2     example where video game addiction became just a little ridiculous.

A pair of brothers in India were so involved in playing video games     3     they failed to notice their house being broken     4    . Not just once though, it happened     5    (two). Over the course of the 18-hour video game marathons each day, the brothers became so addicted to the game that they managed to ignore everything else,     6    (include) bodily functions and any sort of activity around them —like the doorbell or robbers.

The two, 22 and 19     7    (year) old, went without eating, sleeping, bathing, or using the restroom, and it took 2 years for their parents     8    (do) something about it. Though surprisingly the last straw wasn’t the robberies: it was the lack of bathroom breaks and instead just letting out bodily functions     9     they sat. By the time the brothers     10    (receive) rehabilitation, they had become socially and physically dysfunctional.

Smartphones have become an essential part of our daily lives. However,     1     (protect) younger students’ eyesight and make sure they focus on their studies, Beijing Municipal Education Commission     2     (release) a notice that asks all local primary and middle schools to include rules regarding smartphone usage     3     campus management. Students are not allowed to bring their personal phones to school unless their parents submit     4     (write) applications.

Many schools have taken measures to limit students’ phone use on campus. Before the new     5    (regulate), we teachers noticed that many students     6     (attract) to their phones and absorbed in them. Some     7     lacked self-discipline even played games on them during class.

Danny Wang, a student from Chengdu No.7 High School, agrees with the new policy which can be     8     (benefit) to teenagers. Danny believes that regulating phone use at school is     9     only way to put the focus back on academic performance. Kathy Zhou, a parent from Shanghai, allows her daughter to take her phone to school. Zhou says it’s more important to cultivate kids’ ability to self-manage.

In fact, it has long been debated as to whether middle school students should use phones at school. Once a phone     10     (noticeable) causes students to have a sharp drop in academic performance, they had better stay away from it.

Scientists have found that even adding just an additional 500 steps each day brings significant health benefits in later life,     1     (cut) the risk of a stroke and heart problems.

The new study analysed health data for 452 people     2     used an accelerometer device similar to a pedometer, worn at the hip (臀部),     3     (measure) their daily step count.

    4     (compare) to adults who took fewer than 2,000 steps per-day, people who took about 4,500 were 77 per centless likely to experience a cardiovascular (心血管) event in the 3.5 years follow-up. It means that every additional 500     5     (step) lowered the risk of heart issues by 14 per cent.

“We were surprised to find that every additional quarter of a mile, or 500 steps, of walking had such a strong benefit     6     heart health,” said Dr Erin Dooley, an     7     (assist) professor of epidemiology at the University of Alabama at Birmingham School of Public Health.

More up-to-date research     8     (find) that health effects can be steady after 4,500 steps, while others suggest between 6,000 and 8,000 is the sweet spot for fighting chronic illness like heart problems and cancer. “Steps are an easy way to measure physical activity, and more daily steps were associated with a     9     (low) risk of having a cardiovascular disease-related event in older adults,” added Dr Dooley, the lead author of the study. “    10    , most studies have focused on early-to-midlife adults with daily goals of 10,000 or more steps, which may not be available for older individuals.”
