It was Dragonboat Day. Shiny white tents lined the waterfront,     1     (provide) shade and refreshments for Dragon Boat paddlers(桨手)from all over California,     2     gathered around the Castaic Lake for a festive competition.

Giggling kids raced cheerfully along the lakeside beach,     3     their parents enjoying the shady picnic areas under the trees along the shore. “It’s a great day out,” said Paul Lin, co-founder for Castaic’s own Dragon Eyes team.

Dragonboat racing has been going on for thousands of years in China,     4     (initial) in honor of the Chinese water dragon deity(神)in an effort to call down rain and avoid     5     (fortune) and disaster.

In the race, a drummer     6     (use) a large traditional wooden drum to keep the paddlers on beat, while a steersman in the back keeps them in their lane.

Lin said a friend got him    7     (involve) in dragon boat racing over a decade ago. In 2018, they decided to host their own festival. “There’s     8     really special to be learned from our dragon boat motto: ‘One Boat, One Beat ’,” he said. “Paddlers come from all walks of life and that kind of     9     (close) with people is nowhere else to be seen.”

“We really want to help expand awareness and grow the sport,” Lin said. “We’re hoping one day it’ll become     10     Olympic sport.”

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.

There is a growing interest in rock climbing. Recently there    1    (be) an improvement in technology and techniques to perform it. The sport is getting more    2    (attract) to many people. Although rock climbing has risks and physical challenges, people still have several reasons to take it up.

Some sportsmen feel that rock climbing can never become boring. This is because you have different places to go climbing. Additionally, there are several challenging routes to climb. If you are tired    3    walls at your location, you may visit elsewhere    4    (experience) other challenging walls.

    5    (obvious), it offers great fun and adventure to people when they go high up on walls. When they push themselves beyond the expected limits, they get    6    sense of achievement. Many people feel that rock climbing also gives them a feeling of    7    (free), as they can go wherever they want.

There are many sportsmen    8    also lake rock climbing as a physical challenge where they always move up the levels. After    9    (cross) a set level, they move to the next and then to the next. And they can always give a fight to their previously achieved    10    (goal). It all depends on their physical fitness and skill levels.

Up to 82 percent of children with healthy mothers are not easy to be obese（肥胖的）, according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only     2    (drink) wine in moderation, is significantly less likely     3    (have)a fat child, scientists say.

And research suggests it could be more to do with nurture(养育)    4     nature, as a mother's lifestyle appears     5    (direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity     6    (reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine     7     fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child     8    (be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical     9    (active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.

According to a review of evidence in a medical journal, runners live three years     1    (long) than non-runners. You don't have to run fast or for long    2    (see)the benefit. You may drink, smoke, be overweight and still reduce your risk of     3     (die) early by running. While running regularly can't make you live forever, the review says it     4     (be) more effective at lengthening life    5     walking, cycling or swimming. Two of the authors of the review also made a study published in 2014    6    showed a mere five to 10 minutes A day of running reduced the risk of heart disease and early deaths from all     7    (cause).

The best exercise is one that you enjoy and will do. But otherwise…   it's probably running. To avoid knee pain, you can run on soft surfaces, do exercises to    8    (strength)your leg muscles(肌肉),avoid hills and get good running shoes. Running is cheap, easy and it's always    9    (energy).If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give    10    a try.
