While most states have laws that prohibit relocating wild pigs, the practice still happens, and is one of the main factors contributing to the recent increase in pig numbers across the United States. “That’s why we did the study. All these pigs are being moved around and we really have no idea what’s happening with them,” said James Beasley, senior author of a new study.
Researchers made the study at the Savannah River Site outside Aiken, South Carolina. Because the area covers more than 310 square miles, Beasley said the researchers could move pigs to new locations within the area and still feel confident they were in an unfamiliar place. South Carolina law prohibits moving wild pigs unless they remain in the same area.
After catching a pig and fitting it with a GPS tracker, the researchers moved it to another location, usually at least 10 miles away, and tracked its movements over several months. The trackers showed the pigs were able to cover a lot of ground within a short time. Over a seven-day period, on average, the wild pigs would make sweeping paths across the landscape, seldom returning to their original drop-off point and often finally ending up several miles away.
The researchers also found that not long after being released, the wild pigs hooked up with other pigs in the area—sometimes joining an existing social group of pigs and other times creating new groups of relocated individuals.
In one example, two pigs from the same group were released more than a mile apart. “They started moving in different directions. Then, one seemed to cross the path of the other one and found that pig,” Beasley said. “They have this really extraordinary social bond.” More study is needed to understand how these social bonds form, but it’s clear that wild pigs are willing to accept unrelated individuals within their social group.
Infamous for the damage they cause to crops and landscapes, the research shows the potential for problems when wild pigs are relocated and the potential risks of them spreading diseases such as African swine fever when they are moved around the landscape. Beasley said, “This type of information is important to developing management plans for responding to new introductions of pig populations.”

Many fishermen complain that dolphins,also a kind of whale,steal their fish.Therefore,they kill thousands of them.In fact,this is not the truth.In reality there are so many fishermen who steal the fish from each other.Some whale hunters say that they catch the animals for scientists.They have to research what whales are eating.For that, they kill them and look into their stomach.The truth is that they only want to sell the meat.Today scientists want to observe live whales for their research.
Many whale families are not protected and thousands of them are killed.Nobody knows if all whale families would survive,even if humans end all whale hunting today.The pollution of the oceans increases fast and the poison gets into the bodies of the animals.Many of them get sick and die.The human being has killed 90%-95% of many whale families.Others are already extinct.
Today some international organizations try to protect whales.They make reports to explain how important and endangered whales are.Now people are becoming more interested in whales and a complete new industry has developed,whale watching,which you may want to learn about.

【推荐2】Port Lympne Reserve, which runs a breeding (繁育) programme, has welcomed the arrival of a rare black rhino calf (犀牛幼崽). When the tiny creature arrived on January 31, she became the 40th black rhino to be born at the reserve. And officials at Port Lympne were delighted with the new arrival, especially as black rhinos are known for being difficult to breed in captivity (圈养).
Paul Beer, head of rhino section at Port Lympne, said: “Obviously we’re all absolutely delighted to welcome another calf to our black rhino family. She’s healthy, strong and already eager to play and explore. Her mother, Solio, is a first-time mum and she is doing a fantastic job. It’s still a little too cold for them to go out into the open, but as soon as the weather warms up, I have no doubt that the little one will be out and about exploring and playing every day.”
The adorable female calf is the second black rhino born this year at the reserve, but it is too early to tell if the calves will make good candidates to be returned to protected areas of the wild. The first rhino to be born at Port Lympne arrived on January 5 to first-time mother Kisima and weighed about 32kg. His mother, grandmother and great grandmother were all born at the reserve and still live there.
According to the World Wildlife Fund, the global black rhino population has dropped as low as 5500, giving the rhinos a “critically endangered” status.

【推荐3】Arens, a driver of a delivery company, was making his rounds near a pond in Bozeman, Montana, when he heard an unearthly sound.
It was December 2018, and about 15 feet from the frozen banks was the source of that cry — a half-submerged brown-and-white wirehaired dog, struggling to hold on to a thin layer of ice.
How she got there no one knows, but an elderly man was already on the scene, determined to save her. The elderly man had entered the pond in a rowboat and was hacking away at the ice with a rock to create a path to the dog. It was slow going, and Arens, 44, thought he stood a better chance. He took off his clothes, even though the temperature was -30℃, and jumped into the rowboat.
His heart beating fast, Arens slid closer to the dog and used the other man’s rock to smash away at the ice. He gave himself a strong pull and slipped off the boat, crashing into 16 feet of freezing water. He resurfaced in time to see the dog going under. Using nervous energy to keep warm, he swam about five feet toward her, grabbed hold of her collar, and pulled her to the ice. He then boosted the dog into the boat and slid it back to the shore, where anxious bystanders carried the dog to the home of the rowboat owner.
Once in the house himself, Arens jumped into a warm shower with the dog until they both felt warmer.
A few more minutes in the pond, the vet (兽医) told Arens, and she would have likely suffered heart failure.
The next day, Arens was back working in the same neighborhood when the dog’s owner came over to thank him for saving Sadie.
Arens says, “That special delivery was the highlight of my career.”

【推荐3】One reason disorganization is so often tied to mental health is that it can have a negative impact on the way we see ourselves and the lives we lead. The studied downsides of living in a disorganized environment include a memory impediment (障碍), poor eating habits, and an increased chance of developing mood disorders. There’s also a link between the stress hormone and living in a disorganized space and disorganization can lead to anxiety disorders.
Nearly every mental health downside that comes from disorganization can be improved by getting organized. You’ll feel less exhaustion, enhance your productivity at the office, and greatly improve the quality of your life if you can learn how to become organized.
Though many people recognize and desire the mental and physical health benefits that come from becoming more organized, some don’t know where to begin.
“I advise starting small,” says Natalie Christine Dattilo, a psychologist. “It’s easy to become overwhelmed if you try to tackle an entire room, so you can set yourself up for success by starting with a single drawer, bookshelf, or kitchen closet.” She also suggests making organization more enjoyable by listening to music or an audio-book while you’re at it and “spending time in your newly organized space to let yourself enjoy it.”
When it comes to the process of organizing, Julie Morgenstern, a professional organizer, advises sorting items into categories such as keep, throw, and relocate. She suggests having a place for every item you want to keep, removing items you won’t use, and storing elsewhere seasonal items o decoration you don’t need to access often.
It’s also important to remember that becoming organized includes digital organizing as well. Unsubscribe from things you don’t read, delete emails, make a new folder and move just a few emails or documents a day. Just giving yourself five minutes a day to get organized will get a lot done over the course of a few weeks and will help build habits to stay organized.
1. What effect may disorganization have on us according to paragraph 1?| A．Training our memory. | B．Causing digestive disorders. |
| C．Relieving anxiety and exhaustion. | D．Increasing chances of adjusting our mood. |
| A．Start by cleaning the kitchen. | B．Thoroughly clean the entire house. |
| C．Begin with cleaning up a little item. | D．Listen to the music before you clean up. |
