Since 2008, hunters have illegally killed more than 3000 rhinos in South Africa. The International Union for Conservation of Nature warns that rhinos may die out by 2026. People who hunt and kill illegally are called poachers. The most effective way to watch for and prevent illegal hunting is from the air. However, piloted flights are too costly. Fortunately, some Spanish college students have invented a drone (无人机) that can observe more places than a plane.

    Arnau Garcia is an aeronautical (航空学的) engineering student at the Polytechnic Institute of Catalonia, in Spain. He says observers from the air have trouble finding poachers when they hide under the trees. Mr. Garcia and other students have worked with the drone manufacturer HEMAV to help find the hidden poachers. They make it by using the thermal camera, which is especially sensitive to body heat. Even when the poachers keep still, it can also keep track of them.

    The drone can fly in the wind up to 55 kilometers per hour. It has an autopilot system, so it memorizes the flight path. The drone also has a microphone, a video camera and a GPS system. These permit it to report accurately where a picture is taken. After each flight, the drone can bring back detailed information about where rhinos are found, the conditions of water and plants in the area, and the positions of suspected poachers.

    Experts say the drone can fly as far as 70 kilometers from the base. It means that it could quickly observe large areas for poachers. However, the same search operation would take days for human observers. Thanks to the drone, many poachers have been caught and the number of rhinos is on the increase. In addition, HEMAV has received an increasing number of orders for the drone. Even South African national park officials attempt to fill the air with drones.

    San Francisco has its cable cars. Seattle has its Space Needle. And, Longview has its squirrel bridge. The bridge, which has attracted international attention, is now a local landmark.

    The Nutty Narrows Bridge was built in 1963 by a local builder, Amos Peters, to give squirrels a way to cross the busy road without getting flattened by passing cars.

    The original bridge was built over Olympia Way on the west edge of the library grounds. Before the bridge was built, squirrels had to avoid traffic to and from the Park Plaza office building where office staff put out a nutty feast for the squirrels. Many times, Peters and others who worked in and near Park Plaza witnessed squirrels being run over.

    One day Peters found a dead squirrel with a nut still in its mouth, and that day's coffee break discussion turned into squirrel safety. The group of businessmen cooked up the squirrel bridge idea and formed a committee to ask the blessing of the City Council(市政会).The Council approved, and Councilwoman Bess LaRiviere named the bridge “Nutty Narrows.”

    After architects designed the bridge, Amos Peters and Bill Hutch started Construction, They built the 60-foot bridge from aluminum and lengths of fire hose(消防水带). It cost 1,000.

    It didn't take long before reports of squirrels using the bridge started. Squirrels were even seen guiding their young and teaching them the ropes. The story was picked up by the media, and Nutty Narrows became know in newspapers all over the world.

    In 1983, after 20 years of use, Peters took down the worn-out bridge. Repairs were made and crosspieces were replaced. The faded sign was repainted and in July 1983, hundreds of animal lovers attended the completion ceremony of the new bridge.

    Peters died in 1984, and a ten-foot wooden squirrel sculpture was placed near the bridge in memory of its builder and his devotion to the project.

    Judge Frank Caprio is a famous person in the city of Providence, Rhode Island. And, he is starting to get noticed around the world, too. He is an 80-year-old judge in the capital city of Rhode Island, the smallest state in the U. S.. One of his jobs is to take charge of traffic court. That involves talking to people who have gotten traffic tickets for going though red lights or parking illegally. They go to traffic court to question the tickets. Caprio hears what they have to say. Then, he decides whether or not the ticket is legal.

Caprio recently heard the case of a young man who was driving his mother's car. He went through a light after it turned red. After he spoke with the high school student, Caprio decided to let him off with a warning—if he promised to go to college and graduate.

    Another video from the Providence traffic court came out earlier this week. It showed a woman speaking with Judge Caprio about a parking ticket. She went to traffic court after getting a ticket for parking in an area that only permitted parking after 10 a. m. . The ticket was written at 9:59 a. m. . The woman said the clock in her car showed 10 a. m., so she thought it would be OK. After some conversation, the judge decided to dismiss the ticket.

    But Caprio did tell her, “You violated the city laws.” He held up a large book of rules. He smiled and the woman laughed. He said: “Our parking enforcement officers are second to none in the country!” After talking with the court officer, he said “I think 9:59 is close enough. Matter is dismissed.”

    The video was viewed over 1 million times in just two days. One person wrote of the video: “This is so cute. What a great judge. LOVE THIS.” Others wondered if the video was real, because it seemed so funny. But, there actually are judges out there like Frank Caprio. He is as real as they come.

    Read about a normal day in the lives of two children.

    Abbey gets up at 7:00 am, feeds the dog, and has cereal and a glass of juice for breakfast. She walks to school with her friend, Julia. She has a bag of chips for a morning snack, drinks water, and has a chicken and lettuce sandwich with a banana for lunch. She likes to play soccer with her friends at lunch and morning break time. She walks home with Julia, has some crackers with cheese and juice for afternoon snack and plays with the dog for a while. She plays computer games for an hour or two before dinner, then has a shower and does her homework. She watches her favorite television show for an hour, then usually goes to bed at about 9:30 pm.

    Carl gets up at 8:30 am and has two pieces of bread with jam and a glass of milk for breakfast. His mother drives him to school on her way to work. He eats cookies with juice for morning snack and a pot pie ordered from the school lunch room with juice for lunch. He likes to play card games with his friends at lunchtime and climb the fixed equipment at morning break time. He catches the bus home, has a cereal bar and a can of soda for afternoon snack, then watches some television. He has a shower before dinner, then plays the computer for an hour or two. He goes to bed at about 10:30 pm.

    Latrice Brown was excited about starting her junior year. She had volunteered to take part in the Lincoln High School Friendship Program. As an upperclassman, she would be assigned a “freshman(新生) friend”. Her duties would include helping her friend get used to high school life by offering friendship. Latrice thought it was important to have someone with whom to talk and share concerns. She knew that the friendship program was likely to make the freshman year of high school a positive experience. On August 2nd Latrice received a notice in the mail about the schedule of events for the freshman orientation (适应指导).

Freshman Orientation

    Please call your freshman friend and introduce yourself over the telephone.

    Confirm that he or she will be attending the orientation.

    One day, a patient came to see me. He worked as a waiter in a restaurant and his problem was acid reflux (胃酸倒流), a disease that influences as many as 40 percent of Americans, a marked increase in recent years. Reflux can lead to esophageal (食道的) cancer, which has increased by about 500 percent since the 1970s. The drugs we use to treat reflux don't always work and may even increase the risk of developing cancer when used long term.

    What is responsible for these worrying developments? For one, our poor diet, with its huge increases in the intake of sugar, fat, soft drinks, and unhealthy foods. But another important fact has been overlooked: dinnertime. Over the past twenty years, the time of my patients' evening meals has become later and later. Dinner — already pushed back by longer work hours — is often further delayed (推迟) by activities such as shopping and exercise.

    In my experience, the single most important treatment for reflux is to avoid late eating. A patient with reflux came to see me because her father and uncle died of esophageal cancer, and she was afraid of getting it too. Her nightly routine (常规) included a 9 p. m. dinner with at least two bottles of red wine. The reflux was serious, and changes were needed.

    She listened, then did not come back to see me for a year. “For the first two months, I just hated you,” she told me, “and for the next two months, I was having some trouble eating. I guessed I was going to die of esophageal cancer.” Then she added, “You know, we're the reason that it's not so easy to get 6 p.m. reservations (预约) at the good restaurants anymore.”

    To stop the increase in reflux disease, we have to stop eating at least three hours before bed. As for my waiter patient? I told him to eat dinner before 7 p.m. Within six weeks, his reflux was gone.
