According to     1     new study by the World Health Organization (WHO), about 25 percent of adults worldwide do not get enough exercise. Because of this, about 1.4 billion people are       2     greater risk for       3     (dead) diseases such as heart disease and cancer.

When it comes to       4     (exercise) more, experts say that people needn’t go to the gym every day. There are other ways to exercise. For example, we can take the stairs instead of taking an elevator. And standing on one leg for 30 seconds each day       5     (be) also good for our health.

The study also found that women are less active than men because       6     tend to spend more time at home taking care of       7     (child) and doing housework.

Countries with higher incomes showed higher rates of inactivity. For example, people in Kuwait and the United States exercise less       8    people in Uganda and Nepal.

A swing (秋千) could be important for learning, according to one girls’ school. At Brighton Girls, a private school for children     1     (age) 4-18, a swing is to be installed in the sixth-form study center after some of the teenagers asked for one.

After some research, the headmistress, Rosie McColl, said she discovered a swing would be     2     (benefit). She said, “I knew     3     student in a previous school who used to go out and swing in a park between lessons.     4     (current), what we are doing is bringing the swing into the school     5     (help) build a culture. This leads to better results     6     students in terms of both their wellbeing and academic achievement.”

Recent studies show physical activity can improve brain function as well as calming the mind and body, at a time when     7     (anxious) among teenagers is at record levels. So far, McColl’s decision     8     (support) by parents, including Sam Cartwright-Hatton, a psychologist at Sussex University,     9     wrote a letter to the government before schools returned in September calling for new, more creative lessons to help children settle back into class.

McColl advises students     10     (prepare) for exams over the Christmas holiday to find a swing in a local park between revision classes. “No one is ever too old to go on the swings, to play, to think and to dream,” she said.

Over a year ago, before Ke Jie, one of China’s and the world’s best Go(围棋) players, battled with AlphaGo, the artificial intelligence (AI) machine     1    (develop) by Google’s Deepmind team, he was     2    (confidence) that he would win-----even though the program     3    (defeat) top ROK Go player Lee SE-dol only two months before.

But then 19-year-old Ke lost. In an interview with CGTN after the match, he admitted, “AlphaGo can see the whole universe of Go, but I can only see a small pond in my backyard,” Ke said. “So, please, let     4     explore the universe, but let me play in my own backyard.”

His     5    (fail) against the AI program didn’t get him discouraged, but made him a better player. He recognized     6     set human beings and intelligent machines apart was the ability of humans to enjoy the game.

Ke set about     7    (update) his Go skill, and since then he has been unbeatable.

Only a few days before that, Ke had won the 23rd Samsung Cup, becoming the     9    (young) Go player to win six international championships.

Today’s Ke,     10     a Go player, is trying to be the best player he humanly can.

My dad is an enthusiastic(狂热的) runner who     1    (great) influenced me when I was young. So I was very sporty before the age of 14. However, when my family moved, my new school didn’t pay much attention     2    sports and had no after­school activities like football or running. Over the next few years, I stopped exercising apart from during Physical Education lessons at school. I looked like I was     3    (health); however, I was not.

One day, I was late for a bus, tried to run after it and in under a minute was out of breath! This made me realize how unfit I was.     4    (help) myself get in shape again, I made a(n)     5    (decide) that I would take up a kind of sport.

A friend of     6    (I) suggested a swimming pool close to my house     7    she goes to a few times a week. Now, I’m a swimming lover! I find swimming in the pool very     8    (relax). I swim for an hour three times a week. I hope     9    I will soon start to feel the benefits of regular exercise, and will become     10    (fit) than before.
