Dolphins (海豚) are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this way they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brain is nearly the same size as our own, and they live a long time — at least twenty or thirty years.
Like some animals, dolphins use sound to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.
Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.
There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903 Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered (恢复) and for nine years more continued to guide all ships through the area — except for The Penguin.
Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

【推荐1】In the U. S. state of Washington, a road called Interstate 90 cuts through a wild mountainous area to reach the city of Seattle. For the area's many kinds of animals, the busy highway greatly limits their movements. Animals need to move to find food, to find mates and to find new places to live. Crossing I-90 as the road is called is a risky but sometimes necessary act. But soon, animals will have a safer choice.
To help the animals, the state is finishing work on its largest-ever wildlife bridge. The 11-meter-tall, 20-meter-wide bridge begins in the forest. Workers are adding fencing anti-plants to help guide the animals across the bridge. The I-90 bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges, and some are underpasses. They all aim to keep drivers and animals away from each other.
A U.S. Transportation Department study found crashes between animals and humans rose year by year. The accidents made up about 5 percent of all crashes nationally, and cost the economy about $8 billion. Such costs come from car repaid, emergency room visits and removal of the dead animals on roads. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. The study also found that 21 endangered or threatened species in the U.S. are affected by vehicle hits.
Patty Garvey Darda of the U. S. Forest Service says the $6-million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. “If you shut down Interstate 90, you shut down interstate trade.” she adds.

【推荐2】The quiet residential street in Glendale, Calif, has become a battleground in California’s annual fight against wildfires, with about 300 goats deployed to combat the threat. These goats are strategically spread across the foothills and steep ridges of the Verdugo Mountains, where they eat dried-out vegetation that flourished after recent rains.
Despite the hot 94°F heat, these goats tirelessly munch on (咀嚼) dead grass, scrubby bushes, cactus, and even invasive plants like star thistle and black mustard. Michael Choi, the owner of Fire Grazers Inc, is amazed at their ability to consume even thorny (带刺的) plants.
Fire Grazers Inc. is a family-owned business that uses goats to clear brush from challenging terrain (地势). This year, the company is busier than ever due to increased demand following a rainy winter that led to more vegetation growth. Choi has extended the grazing season by a couple of months, and he’s added more goats to keep up with the workload, bringing the total to about 900.
The goats clear about 1 acre of vegetation each day. They are transported to various sites, including wealthy areas with challenging terrain, where they help reduce the risk of wildfires. Targeted grazing (放牧), an age-old practice, is important in California’s wildfire risk reduction strategy, especially after years of devastating wildfires.
Patty Mundo, vegetation management inspector for the Glendale Fire Department, said it was local residents who suggested the idea of the goats two years ago. Since then, she’s brought Choi and his goats back for an annual “Bleat and Greet” event, where the community is invited to get to know the fire-fighting heroes. It’s a great way to raise awareness about the importance of proper land management, Mundo said.
Compared to traditional brush crews that rely on power tools and equipment, goats are cost-effective and environmentally friendly. They only require water, minerals and the protection of an Anatolian shepherd dog.
Choi takes pride in contributing to the safety of California’s communities. As the goats graze, he reflects on the potential of these animals to create firebreaks that could save homes and lives, giving firefighters crucial time to respond to emergencies.

【推荐3】Pangolins are the most trafficked(非法交易)mammals in the world and are facing extinction. To draw attention to these scaly(有鳞片的), anteater-like animals, a new wildlife documentary, Eye of the Pangolin, is attempting a unique way to inspire action and conservation: access. Partnering with the non-profit organization Pangolin. Africa, the documentary was made available on YouTube in May 2019. The intention is to reach communities wherever the Internet is available, especially African communities, who live near the animal’s habitats.
Over two years,the documentary crew traveled to South Africa, Ghana, Central African Republic and Gabon in search of the four unique species of pangolin, which has never been achieved before. Filmmakers Bruce Young and Johan Vermeulen say that they went into the shoot knowing relatively little about pangolins, but grew to respect and appreciate the animals. Getting close to the creatures over two years was a crash course in these secretive creatures. Johan Vermeulen said, “One thing however that might seem unimportant is that they are actually quite fussy eaters. You would think they would eat any type of ant, but they all prefer a specific type ant.”
Pangolins are hunted illegally across Africa for their scales, which are used for traditional medicine, and their meat. In April 2019, Singaporean customs officials conducted two separate seizures of 24 tons of pangolin scales, which equals to the death of 69,000 pangolins.
Though the documentary focuses less on the trafficking of pangolins, and more on the animals in their natural habitat, the aim of the documentary is to inspire viewers around the world to call for action to end trafficking and protect these unique creatures.
Filmed on location in South Africa, Ghana, Central African Republic, and Gabon, this powerful documentary is the story of two men a mission to get all four species of African pangolin camera for the very first time.

【推荐1】Getting hit on the head can cause a serious injury. Sometimes, even if a person feels okay, they may have a brain injury called a concussion (脑震荡). Even a good doctor can have trouble telling if a person has a concussion or not. And if a person is not careful and gets hurt again while they have a concussion, the problems can be even worse. Now Neurology researchers at the University of Pennsylvania think they may have found a solution—an easy-to-use two-minute reading test that can assess (评估) the possibility that a concussion has occurred.
The test was originally designed to test reading skills in children, but it also catches problems with vision and eye movements, which makes it useful for studying concussions. The test consists of a series of numbers arranged in zigzagging (锯齿) patterns on cards, which children read from left to right as quickly as possible. The Pennsylvania researchers tried out the test on boxers and martial (武术) arts fighters in a study earlier this year and found it worked well as a predictor of head injury.
The researchers gave the fighters the test before and after a match. Typically people can complete the test faster the more times they take it, says Laura Balcer, a lead author of the study. But the athletes who had experienced head injury during their fights read the cards more than 11 seconds slower when they took the test a second time. Fighters who had a concussion read the cards especially poorly, worsening by 18 seconds on average.
Now Balcer and her colleagues are studying the test’s ability to predict concussions in athletes who play football and other rough sports. Their goal is to create an evaluation tool that could serve as an early warning sign for coaches, who would need only the cards and their stopwatch to determine whether a player needs to be sent to a doctor.

【推荐3】In the past ten years, many scientists have studied the differences between men and women. And they all got the same answer: The sexes (性别) are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways.
Boys, for example, generally are better than girls at mathematical ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally see better in the dark than boys and are better at learning foreign languages.
What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve (神经) tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation (创造) and the expression for emotions (情感). In men and women, different areas in each side of the brain develop differently. In boys, for example, it’s the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man’s brain are connected by a smaller number of nerves than the two sides of a woman’s brain are.

【推荐1】Polar bears have captivated(迷住) humans since the beginning of recorded time. Writings dating back to 57 C. E. in ancient Rome describe flooded amphitheatres where polar bears and seals competed against each other ( not much of a fight, as it turns out). Kings of ancient Egypt and early Norway were the first to keep polar bears captive, and the fascination with them has held through the centuries. Ad campaigns all over the world feature polar bears to sell everything from bottled water to transportation systems to soda.
A Coca-Cola ad campaign in the 1990s added "adorable" to the polar bear's image. The ads featured a clumsy, animated cub that bridged the natural wariness between polar bears and penguins to share a nice, cold bottle of Coke. Polar bears don't actually have a natural affinity for penguins, as the two don't live in any of the same regions and never see each other. But still, cute is cute.
Polar bears' shocking whiteness, ferocity and sheer size make them icons of purity and power. Males can grow up to 10 feet tall (3 meters) and weigh up to 1,500 pounds (680 kilograms). A single bear can take on a 2,500-pound walrus, and hang on to the massive catch with 2-inch claws (5 centimeters). They walk hundreds of miles across ice sheets every winter, following their prey.
In the Arctic, polar bears are at the top of the food chain, and it’s not just because of their size. They're so well-adapted to their environment that they experience no change in body temperature at minus 34 degrees Fahrenheit ( minus 37 Celsius). However, the incredible survival mechanisms that let them thrive in frigid winters may prove to be their undoing. Because of global warming, winters are getting less cold and polar bears are dying. Some scientists project that if climate trends continue, 30 percent of the current polar bear population will be wiped out by 2050. What’s life like for an animal that needs such extreme cold to survive? Let's head to the Arctic and see how polar bears live on the ice.

【推荐2】Do you fancy seeing some sights that aren’t heaving with other visitors? You might have to travel a bit off the beaten path while you’re in Italy. We’ll take you through four of the best hidden gems that you can find in the country.
Chioggia, Venetian Lagoon
Arranged across five islands, Chioggia is enchantingly spliced by beautiful canals. The adjoined town of Sottomarina throws in a six-mile sandy beach. Further south are more beaches plus empty riversides lovely for cycling—which, unlike Venice, one can also do in Chioggia.
San Nicolò dei Mendicoli, Venice
San Nicolò dei Mendicoli church was a key filming location in the 1963 film Don’t Look Now. “Mendicoli” is translated as “beggars” in Venetian language; this area once housed poor fishermen and the church used to shelter the homeless. Beyond set-jetting (电影主题旅游), further incentive to visit is provided by some superb Renaissance ceiling frescos and the celebrated Resurrection of Christ oil painting.
Borromini’s Perspective, Rome
There’s a beguiling reason to visit this impressive Centro Storico palace. On its first floor, find a peaceful orange tree courtyard and look down the colonnaded (柱廊式的) gallery whose distant statue of Mars is about 35 metres away. In fact, the passage is actually only eight metres long, and its god of war merely 60 centimetres high. Not that you’ll believe it until stepping forward.
Santa Maria Novella Pharmacy, Florence
In Florence, visiting one particular apothecary (药商) is a must, partly because the Santa Maria Novella is thought to be the world’s oldest pharmacy. Today, while admission to the neighbouring, tremendous Basilica (大教堂) costs €7.50, pharmacy entry is free. Friendly staff will guide you through handmade soaps, lotions, potpourri (精油) and fragrances made according to centuries-old recipes.

【推荐3】Saddle attached. Mount up. Reins in hand. Racing with the wind and jumping to the sky, freshmen Natalle Gordon and Lauren Tate become one with their horses. Gordon and Tate participate in equestrian (马术) jumping and hunting with the Texas Rose Horse Park and King’s Equestrian organizations. They will be competing in jumping and hunting events during October.
“My favorite part about riding and jumping is the high speed,” Gordon said. “I’ve had a lot of exciting and crazy moments.” Gordon has been riding for 4 years and participates in hunting events, a slow and complicated variation of jumping. Hunting events are subjectively judged based on how well the horse performs over fences. The pair of rider and horse is judged on style, pace, and manners as well.
Gordon’s horse, Casino, is a Welsh pony. Together the two have achieved impressive results including first place in a Derby, a large competition in the equestrian world, which was a big accomplishment.
Tate, on the other hand, participates in jumping events and has been riding since childhood. Jumping is a fast paced and less formal event. Jumping is scored objectively. The horse and rider’s goal is to clear all the fences in the course as quickly as possible without making any mistakes by knocking over the bars of the fence.
“It’s a speed round,” Tate said. “You just have to be the fastest person and get to the jump and win.” Tate’ horse, Chief, is a Chestnut Appendix. Together they have gotten champion awards in jumpers. “I love Chief,” Tate said. “I’m really proud of the work we’ve done together.”
Both Tate and Gordon have bonded through horse riding. Along with bonding with each other, they have established a deep love of their horses. “It’s you and your horse out there,” Tate said. “You are never alone. You’re partners through it all.”
