Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

    Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

    There are many environment-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

    Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements（代替物）for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

    A walk through the galleries of Quebec's Montreal Museum of Fine Arts (MMFA) places individuals face-to-face with some 43,000 artworks ranging from Chinese ceramics(陶瓷制品) to Inuit sculpture.

    While the visiting is an incredible cultural experience, a group of local physicians will soon be able to prescribe(开处方) museum visits as treatment for some illnesses.

"We know that art contributes to neural(神经的) activity," said MMFA director Nathalie Bondil. "What we see is that being in contact with art can really help your well-being."

Hélène Boyer, vice president of a Montreal-based medical association, explains that museum visits have been shown to increase levels of serotonin, a neurotransmitter(神经传导物质) known as the "happy chemical" which helps to lift mood.

    According to Boyer, the small increase in hormones(荷尔蒙)associated with enjoying an afternoon of art is similar to that offered by exercise, making museum prescriptions ideal for the elderly experiencing pain that prevents them from regularly joining in physical activity.

    The museum visits are designed to improve traditional methods. As Bondil notes, spending time in a peaceful environment can provide a welcome distraction. "What is most important is this experience can help them escape from their own pain," she says. "When you enter the museum, you escape from the speed of our daily life."

    "I am convinced that in the 21st century, culture will be what physical activity was for health in the 20th century," said Bondil. "Some people would do well to recall that just in the 19^th century, sports were believed to do harm to the body. Just as doctors now prescribe exercise, they will be able to prescribe a visit to the MMFA."

    30 November 2017,Serbian tennis player Novak Djokovic defeated Scottish Andy Murray 6-1,7-5,7-6 in the Australian Open 2017 final to win the Grand Slam event (大满贯)for the sixth time. Murray has lost five Australian Open finals, facing Djokovic in all but one of them.

I'm sure you'll have more opportunities to fight for this trophy”.Murray congratulated Djokovic, saying “I feel like I've been here before. Congratulations, Novak. Six Australian Opens is an incredible feat (业绩).The last year has been incredible. Good job.” He also left a message for his wife Kim Sears,“I'll be on the next flight home.” The couple is expecting a baby.

    Yesterday, Jamie Murray, Andy Murray's elder brother, won the Australian Open Men's doubles with Bruno Soares. Andy Murray was there in the audience, recording his brother's speech, to which Jamie said,“Andy, you should be in bed!”

    Television in the United States is free. To pay for programs, there are many advertisements. Often these advertisements are short plays with actors. The following television advertisement is like many others that Americans see daily.

    We see a man and his wife at the breakfast table. They have been married for a long time. They are not speaking to each other. They haven't spoken to each other at the breakfast table for years. The husband is reading his newspaper. We can't see his face. The wife looks very bored as she pours a cup of coffee for him. Today, she is using a new kind of coffee for the first time. The husband picks up his cup. He isn't very interested. He tastes his coffee. Suddenly he puts down his newspaper. Something is different. Can it be the coffer? He takes another taste. It's wonderful. He smiles. He looks at his wife and says in amazement, “Doris, when did you cut your hair?” Doris is pleased. She answers, “Two months ago.” Doris asks, “Herbie, when did your hair begin to turn grey?” He replies, “A long time ago.” Doues says, “Oh, very handsome.” Now they aren't bored anymore. Breakfast is different. Having a new kind of coffee changed their lives.

    What's best to read this year?

    Secrets I Know (Random House Children's Books, ages 3-7)

    This tale written by Kallie George and pictured by Paola Zakimi follows a young girl and her little friend as they move from rain to sunshine, from pleasant loneliness to sweet friendship, and finally from adventures on earth to an exploration of the sky above. The colors of Zakimi's pencildrawings are calming and George's poetic text tells her story with simple language.

    Pandora (Clarion Books, ages 3-7)

    The award-winning author Victoria Turnbull tells the story of a little fox Pandora. Pandora lives alone. She makes herself a handsome home, but no one ever comes to visit. Then one day something falls from the sky -- a bird with a broken wing. Little by little, the bird helps Pandora feel less lonely. Turnbull's watercolor and colored pencil drawings make this story of friendship and growth an atmospheric delight.

    Prince and Pirate (G.P. Putnam's Sons Books for Younger Readers, ages 5-8)

    A different kind of friendship is described in this book, by Charlotte Gunnufson with pictures by Mike Lowery. Prince and Pirate are a pair of mismatched fish put into the same aquarium（水族馆). At first it seems that they'll never learn to be friends. It's only when both take pity on a frightened dogfish that they learn the benefits of cooperation, and soon all three fish become good friends.

    The Giant Jumperee (Dinal Books, ages 3-5)

    The story was written by the award-winning British author Julia Donaldson. When Rabbit hears a loud voice bellowing（吼叫）threateningly from inside a cave, he gathers Cat, Bear and Elephant to help him decide what to do. But it's Mama Frog who fearlessly confronts（面对）the unknown creature. Helen Oxenbury's soft watercolors creat a beautiful countryside and her characterizations of the animals are impressive.

The outbreak of locusts, an insect that mainly lives in Africa and Asia, is the worst experienced by Kenya in 70 years. The crowds are some three times the size of New York City, eating their way through thousands of acres of crops and animal grassland and destroying livelihoods in the process.

"These hungry things are alarming," says Keith Cressman, the UN Food and Agriculture Organization's senior locust forecasting officer. "A crowd the size of Manhattan can, in a single day, eat the same amount of food as everyone in New York and California combined."

Desert locusts are infamous for their ability to breed(繁育)rapidly in large numbers every three months. And with some help from the wind, they can travel as much as 80 miles a day. Most years, the insects stay in African deserts. However, under the right environmental conditions, they can multiply quickly, spread as much as 400 times every six months and cause extensive destruction if left unchecked.

"The insect has the ability to take advantage of good conditions." Cressman says.

The "good conditions" the scientist is referring to began in mid-2018 when a rainstorm from the Indian Ocean struck a remote area of the Arabian Peninsula known as the "Empty Quarter". Normally, it would dry out within a short period, killing most of the locust population, which depends on green plants for food. However, in late 2018, a second rainstorm struck the same region. The huge sandy area got wet, which is exactly what desert locusts need to lay their eggs and breed. The extra food supply caused the population to explode for the second time in six months.

Luckily, the locusts, experts say, are easy to control with chemicals. Kenya badly needs equipment and a steady supply of chemicals to effectively wipe out the massive insects. Hopefully, leaders worldwide will recognize the tough situation and contribute generously to control the locust outbreak.
