Mickey Mouse and Shrek are just a couple of the American animated (动画的) characters loved the world over. And they are examples of the evolution of animation, which has brought unique new life to the film industry.
Among the first American animated films was Light of the Moon, a silent movie produced in 1911 using silhouette (剪影) animation, where the characters are represented only as black silhouettes.
The real breakthrough for American animation came with Steamboat Willie, created by Walt Disney and released in 1928. It was the first animated film to be accompanied by sound, and its main star, Mickey Mouse, became one of the most loveable and enduring animated characters ever created. Disney also created the first American full-length animated film, Snow White and the Seven Dwarfs. Released in 1937, it enjoyed worldwide box-office success.
Disney’s extremely careful attention to high-quality detail in the thousands of hand-painted drawings required at that time to make an animated film elevated this film technique to the level of a serious art form.
Clay animation is a type of stop-motion animation using forms made of clay. Clay animation films have been produced in the United States since 1908. But this form of animation only won wide popular appeal in 1955 with a short film called Gumbasia, created by Art Clokey.
Computer-generated imagery, or CGI, brought animation to a new level of artistry and realism. Used in film since the 1960s, CGI animation began to develop rapidly in the mid-1990s. Toy Story, released in 1995 and created by Pixar and Disney Studios, was the first completely computer-generated animated feature film.
In 2001, DreamWorks and Pacific Data Images released Shrek, the first computer-animated feature film to win an Oscar. Shrek returned in 2004 with his talking donkey, his princess bride Fiona and an army of fairy-tale characters in Shrek 2. Hugely popular, that film became the highest-grossing (票房最高的) animated film of all time.
In addition to strictly animated movies, animation has been mixed into films showing live actors as well. Who can forget the terrifyingly real dinosaurs thundering through Steven Spielberg’s Jurassic Park movies and the actors they chased? Thanks to the powerful capabilities of today’s computers and the unlimited imagination of American filmmakers, animation will be entertaining audiences worldwide for a long time to come.

【推荐1】Lady Gaga’s latest film became an instant hit over the weekend, helping push theaters to an October ticket-selling record.
A Star Is Born, actor-turned-director Bradley Cooper’s remake of a Hollywood classic in the late 1930s, went beyond the previous expectations of movie analysts by roughly 30 percent.
The original production is such a great Hollywood myth that it’s no wonder Hollywood keeps telling it. Whatever the era, the director or the headliners, it tells the story of two lovers on dramatically different paths: a famous man who’s racing to the bottom and a woman who’s soaring to reach the top.
Mr Cooper does a lot right in this movie AStarLsBorn, beginning with the casting of Lady Gaga, whose relaxing, naturalistic performance is the key to the movie’s force.
A post-Madonna pop artist was known for her elaborate (精心制作的)makeup and costumes, which she adopted no more here.
This unmasking of Lady Gaga makes her character seem genuine or say natural, a quality that the movie is in favor of and that serves as a kind of everlasting first principle.

【推荐1】Horseshoe crabs are often called living fossils. These primitive arthropods have lived on earth for 360 million years, largely in the same form as they appear today. Despite their long history, the horseshoe crab’s existence is now threatened by human activities, including harvesting for medical research.
Any time a foreign object or substance enters the human body, there’s a risk of introducing infection. If you’ve had a vaccination, a surgery of any kind, or had a medical device implanted in your body, you owe your very survival to the horseshoe crab.
Horseshoe crabs have copper-rich blood that appears to be striking blue in color. Proteins in the horseshoe crab’s blood cells are released in response to even the smallest amount of bacterial endotoxin (内毒素), such as E. coli. The presence of bacteria causes horseshoe crab blood to clot or gel, part of its hypersensitive immune response system.
In the 1960s, two researchers, Frederick Bang and Jack Levin, developed a method of using these coagulation (凝固) factors to test for contamination (污染) of medical devices. By the 1970s, their Limulus amebocyte lysate (LAL) test was being used commercially to make sure everything from scalpels (手术刀) to artificial hips (髋关节) is safe for introduction in the human body.
While such testing is crucial to safe medical treatments, the practice takes a toll on horseshoe crab populations. Horseshoe crab blood is in high demand, and the medical testing industry catches as many as 500,000 horseshoe crabs each year to drain them of their blood. The crabs aren’t killed outright in the process; they’re caught, bled, and released. But biologists suspect the stress results in a percentage of the released horseshoe crabs dying once back in the water. Fortunately, management practices are in place now to protect the species.
In addition to their value in medical research, horseshoe crabs fill important ecological roles. Their smooth, wide shells provide the perfect substrate (基质) for many other marine organisms to live on. As it moves along the ocean’s bottom, a horseshoe crab may be carrying mussels, barnacles, tube worms, sea lettuce, sponges, and even oysters. Horseshoe crabs deposit their eggs by the thousands along sandy shorelines, and many migratory shorebirds, including red knots, rely on these eggs as a source of fuel during their long flights.

【推荐2】The Yellow River is the cradle of China’s civilization. And flood control and prevention have always been key to the well-being of the people living along it. Now, scientists can better work on these issues by giving the river a digital twin.
The digital twin of the Yellow River uses various technologies, including big data, artificial intelligence, and the internet of things. Devices (设备) set up along the river collect and transmit information to the center. Based on the information, a 3D model of the river is presented on the computer screen. It’s like the Yellow River has a twin that reflects its real conditions.
One big breakthrough in the river’s digital governance (治理) is “smart stones”. According to Wang Qin, a lead researcher at the Information Center of Yellow River Henan Bureau, a smart stone is a water-proof stone-shaped device with chips, a battery, and a signal transmitter. They are buried in important dike (堤坝) locations to record and report the movement of dike stones. “Upon feeling movement of the dike stones, the smart stone sends an alarm to the center for quick response,” Wang said.
“In the past, researchers had to learn the conditions of the dike on the spot by themselves, putting their lives at risk,” said Zhao Xiao from the bureau. “Now the smart stones can do this for us, more safely, quickly, and accurately.”
And in the sky, drones (无人机) are flying. On the routes designed by engineers, the drones become expert patrollers (巡逻员) of the river, looking at its dikes and flood prevention projects. According to Shen Lin from the Yellow River Conservancy Commission, thanks to the drones, researchers at the command center can get first-hand photos and information. “Researchers then update the 3D model according to the changes the drones reported. The newly updated model helps us test our floodwater release plans in case we ever need to batten down the hatches (未雨绸缪), ”said Shen.
Under the water and up in the sky, intelligence systems are helping to protect the Yellow River Basin on all fronts. According to the Ministry of Water Resources, in the future, we can expect to see the construction of an even more comprehensive digital system for this important river.

【推荐3】The northernmost part of Earth is warming two to three times faster than the rest of the planet. The melting (融化的) ice has cleared space through the historically dangerous Northwest Passage. This means the melting sea ice is opening new routes for shipping.
Donna Hauser is a marine biologist with the University of Alaska Fairbanks. Hauser says she was interested in studying the possible threat (威胁) to Arctic marine mammals from shipping.
Hauser says her hope was to protect both these animals and the people who depend on them. “All of these species (物种) are really important for local communities throughout the Arctic as well as in Alaska.”
Hauser and other researchers looked at seven Arctic species. They limited their study to the month of September. This is when sea ice is at its lowest point and most ships pass through Arctic waters. The study found that narwhals and other whales were most at risk to ship traffic during the late summer. Polar bears were the least at risk, with walruses and seals in between.
The noise of ice-breaking boats and other ships is extremely unsettling to marine mammals, notes Kristin Laidre of the Polar Ice Center. “That underwater noise is a disturbance for marine mammals, especially different whale species that rely on sound to do everything.”
This is the first study to compare effects of increased ship traffic on major Arctic marine mammal species, and identify which animals might be most in need of protection. “We’re no longer in an Arctic state that was experienced by British Captain Sir John Franklin in 1845 or some of those early Western explorers,” noted Hauser.
In order to help protect marine animals, the researchers suggest requiring ships to move at slower speeds to reduce the chance of striking. They also suggest a limit on the amount of noise ships can make.
Kristin Laidre says that it is unrealistic to try and stop people from using Arctic passageways. However, by understanding which animals are at risk, researchers can help plan for the future.

【推荐2】One of the key tasks for leaders at GE (General Electric) is to look after the company’s resources. We watch how money is spent and protect the company’s assets(资产) .We make efficiencies(效率) and fight to find funding for new ideas. We care about the health and welfare of our employees,and work to keep them safe all over the world.
Where we sometimes fall short-I am sure this is true of most organizations-is with time.I don’t think we manage time as well as we could. We have meetings that include too many participants,some of whom don’t need (or want) to be there. Too much time is spent at the start of meetings passing around information that could be shared in advance. Some meetings go on longer than they need to, and don’t always result in real actions, or decisions.
Leaders make personal decisions about how to distribute their own time,and this affects how others and particularly their teams have to spend their time. I’ve asked people in my organization to think ahead-what can be done individually or beforehand. We need to think about the impact every time we occupy time, or create work, for others.
Wasting time contributes to a competitive disadvantage. It keeps us from doing things that matter and meeting deadlines. One solution we’re working on at GE is adopting a “FastWorks” mindset. This is a lean start-up concept we developed to better understand pain points, quickly test product or service hypotheses(假设) and to understand if a proposed solution is right. We used this approach to develop our GuardEon circuit breaker in less than half the time it would previously have taken and went to market 3 years sooner.
If you are like me, you have your best days when you accomplish things. The worst days are when we spend time doing things without results, and you come away feeling you have wasted time. We don’t mind working hard, but we want to get things done. The old saying went something like “time is money,”In today’s world, it’s more like “time is speed and focus, and speed and focus is money.”We are more successful if we are focused and spend our time doing the things that matter.

【推荐3】Laughter fills the room as Claire Conza distributes balls of wool to a bunch of women gathered in a Birkenhead cafe on a Wednesday morning.
Conza, 34, is the founder of Make Give Live, a social enterprise that’s brought together about 40 women in five groups to knit(编织)hats. Her “makers” meet each week or fortnight. “We swap finished hats for new wool and patterns to keep them busy until the next catch up,” she says.
Since starting up last year, Make Give Live has sold more than 400 woollen hats on a “buy one—give one” model, so another 250 hats have been given to the homeless or elderly people through partnerships with Lifewise and Age Concern, with more donations to come.
But for Conza, the movement is about more than making hats—she sees Make Give Live as a way to connect communities, share good times and improve well-being. “There’s a magical interaction between the generations within our groups. Our older members are enriched by using their knitting skills to teach younger people. Our younger members have new methods to share and get to create something for their community.”
Makers are also enjoying the health benefits of knitting, which Conza says offers many of the same benefits as meditation(冥想). “The rhythmic movements and sense of focus can help keep from symptoms of anxiety, pressure, and stress.”
“I found so many benefits in the mindful process of knitting and the joy of creating something useful and beautiful, at a time when I wasn’t able to do much else. I decided if it worked for me, others would also benefit, and Make Give Live was born,” she says.
“A social enterprise is a hybrid of a charity and a business,” says Conza. “It’s about having the head of a business, the heart of a charity and the hands of the community. The key to its existence is recognizing people for their efforts so they are able to stay involved.

【推荐2】There are usually few things people want to do less than housework. But while washing the dishes and dusting the shelves seem like trouble some things. A new study has found just how important they are to our general health and happiness.
In fact, scientists now believe cleaning the house is more important to mental and physical health than other factors, such as the area you live in or how much you earn. Researchers at Case Western Reserve University say doing housework is helpful because of the exercise it takes to get the daily job done, which in turn affects mental health.
Dr. Kathy Wright and a research team at the university’s Frances Payne Bolton School of Nursing wanted to find out how property (财产), education, environment and health behaviors, like smoking, affect an older person’s health. The study’s 337 participants, from 65 to 94 years old, had to have at least one chronic (慢性的) illness which prevented them from doing at least one basic daily task, such as bathing and dressing.
Dr. Wright said she was surprised to learn that doing housework and keeping their property affected the participants’ mental and physical health more than other factors. “House cleaning kept them up and moving, ” said Dr. Wright. “A clean environment is helpful in treating some illnesses. And poverty (贫穷) did not directly affect mental or physical health. ”
The study proved what Dr. Wright had observed in her visits: people living in a dirty environment seemed less satisfied than those in a place that was neat and tidy. Dr. Wright hopes the study shows how important it is for older people with chronic illnesses to continue physical activities, such as doing reaching exercise while sitting, standing up and sitting down in a chair.

【推荐3】There are two species of crocodile in Australia—the saltwater crocodiles and the freshwater ones.
Saltwater crocodiles are among the world's largest crocodiles, with males often reaching five metres. But some can reach six to eight metres. Females grow up to 2.5 metres long.
Saltwater crocodiles live in rivers, and coastal waters in northern Australia and eat a wide variety of prey. The young ones stick to insects, small reptiles and fish. But adults hunt for bigger prey like snakes, monkeys and cattle. And they have been known to attack humans.
Freshwater crocodiles, however, aren't usually dangerous to people. They live in freshwater streams, rivers and large water holes in northern Australia. Freshwater crocodiles aren't as big as saltwater ones either, reaching a length of three metres at most.
Crocodiles first appeared 200 million years ago and lived originally on land. But they soon evolved into aquatic (水生的) animals.
These reptiles are excellent predators (肉食动物) and have few natural enemies. Crocodiles have about 30 or 40 teeth in each jaw. And it is the jaw that gives a unique feature to them.
A crocodile can close its jaws with such force that it can break the bones of some animals. Yet, once the jaws are shut, they're so weak that they can be held together by a person's hand.
To reproduce, crocodiles, like other reptiles, lay eggs. One female can produce between 20 and 90 eggs at a time. Once laid, female crocodiles bury their eggs in sand or mud, where they are left to hatch. Some females stay in the area to protect the nest and look after the young after they hatch, but often other predators eat the eggs.
