There's no doubt that man is the smartest. But do you know what other animals are smart, too?

Dolphins

    Dolphins are very smart. Most of the “tricks” they're taught to do are actually behavior they would engage in on their own. They love to play, race and generally enjoy their life to the fullest. They speak a language we have yet to completely understand and like all civilized creatures, dolphins' mothers always provide their young children with guidance and possibly, love.

Great apes

    The great ape family primarily consists of gorillas, chimpanzees and orangutans. Their brain chemistry is so similar to humans' that NASA once used chimpanzees in place of astronauts during many dangerous missions. Gorillas have been taught sign language and orangutans exist in complex familial relationships.

Elephants

    Everyone has heard the phrase “an elephant never forgets”. Elephants establish long-term friendships, recognizing and remembering their friends years later. If an elephant comes upon a fallen friend, it has even been known to feel sad.

Parrots

    As proved by this list, parrots are very smart. They are also the only animals listed that can actually hold a conversation. Some parrots know hundreds of words by imitating humans. The birds are also capable of remembering words and using them intelligently in response to situations.

    An organization, Eye Care 4 Kids, is bringing much-needed eye care to poor kids. It provides free eye examinations for kids from poor families. Founded by Joseph Carbone in 2001, the organization has helped around 100,000 children in Utah and Nevada.

    Now, Cecil Swyers, a biomedical(生物医学的) engineer who was once a poor child himself, is bringing the charity's(慈善) services to poor students in Arizona, so that vision impairment(视力受损) doesn't stand in the way of their education.

    “Eye Care 4 Kids is bringing eye care and glasses to families that wouldn't have the means to pay for them,” said Mario Ventura from Isaac Elementary School District, the first school district in Arizona to receive its services.

    Good vision is important to a child's learning experience. According to a study, up to 80 percent of learning happens through sight for children between 6 and 18 years old. Without proper eye care, it's difficult for students to learn better and succeed.

    Swyers is hoping that by bringing the organization to Arizona he'll help a lot more students. He teamed up with two other organizations to get doctors to volunteer their time with the group. Using an Eye Care 4 Kids mobile clinic, Swyers visited Alta E. Butler Elementary School and has already helped 40 students.

    The school was grateful to receive the eye care, especially since the services came to them. “It's great for us,” said Assistant Principal Cindy Alonso.

    Swyers is hoping to bring Eye Care 4 Kids' services to other schools in the state. He said that hopefully his work will have a positive effect on students' futures. “If we can help students while they're young, we can make a difference in their futures,” he said.

    Many people discover Roald Dahl through his stories and poems. His books have been translated into several languages. He has also inspired TV and radio shows and movies. With his help, kids all over the world can imagine strange candies, friendly giants, and frightening villains(反派主角). Indeed, Roald Dahl led a life full of adventures (冒险). Yet, we can have a better understanding of him from other things, too.

    More than Just Words: The Roald Dahl Foundation

    Roald Dahl became interested in helping people who had serious injuries and diseases. As a writer, Roald cared about helping children read more. To carry out these goals, his family set up the Roald Dahl Foundation. The foundation helps people, hospitals, and charities by giving money for medical and educational needs. It continues the spirit of giving that Roald expressed throughout his life.

    Stories for All Ages: The Roald Dahl Museum and Story Centre

    Roald Dahl's wife, Felicity Dahl, wanted to set up a central place to protect all of Roald's writings. She helped create the Roald Dahl Museum and Story Centre in Buckinghamshire, England. It holds a collection of Roald's writings and recordings for the public to visit. His personal letters and postcards can be found there, as well as photographs and many of his awards. As you can see, one can get a pretty complete picture of Roald Dahl's life by visiting this library. The museum also encourages people to write creatively.

    Now, people of all ages are learning about Ronald Dahl through his works. Through his stories, the foundation, and the museum, Roald Dahl will continue to have a great effect on readers around the world for years to come.

    A farmer had a cow, and he took very good care of the cow. One day when the cow was ill, he was very worried. He telephoned the vet.

    "What's the problem?" the vet asked the farmer when he arrived.

    "My cow's ill," the farmer said. "I don't know what's the matter with her. She's just lying down and doesn't eat anything. She's making a strange noise."

    The vet examined the cow and said, "She's certainly ill, and she needs to take some very strong medicine."

    He took a bottle out of his box, put two pills into the farmer's hand and said, "The pills should make her feel better."

    "How can she take these pills?" the farmer asked.

    The vet gave him a tube(管子) and said, "Put this tube in her mouth, and then put the pills in the tube and blow(吹气) into the cow's mouth. That will make it."

    The next day the vet came to the farm again. The farmer was sitting outside his house and looked more worried.

    "How is your cow?" the vet asked.

    "Not better," the farmer said, "and I'm feeling very strange myself."

    "Oh?" the vet asked. "Why?"

    "I did what you said," the farmer answered. "I put the tube in the cow's mouth and then put the two pills in the tube."

    "And?" the vet asked.

    "The cow blew first," the farmer said.

    Helen Keller was one of America's best-known women. She was admired for her courage and achievements although she couldn't see or hear. She was also known throughout the world for herself-sacrificing work to improve the condition of the blind, the deaf and the speechless. When she died on June 1, 1968, the newspaper Washington Post wrote: "Her life was truly one of the most remark able phenomena of our time and her death just short of the age of 88 leaves the whole world poorer."

    Helen Keller was born on June 27th, 1880, in Tuscumbia, Alabama. For the first 19 months of her life, she was a pretty and happy baby, normal in every way. Then a sudden illness destroyed her sight and her hearing. Because she could not hear sounds to imitate(模仿), she could not speak. Helen used to say that her real birthday was not June 27th, 1880, but March 3rd, 1887—the day when Anne Sullivan entered her life. It was Anne Sullivan who taught Helen to spell certain words by a special system, Braille, and even to talk.

    Anne Sullivan could not teach Helen Keller to speak until some other important things had been learned. The little girl had to learn to control her actions and feelings. She had to learn that she could not always do what she wanted to do. She had always been able to get what she wanted by using force. The teacher had to change such habits without breaking the child's spirit.

    Miss Sullivan's battle began. Sometimes, there was real fighting between the wild child and the strong young teacher. At last, however, the battle was won by Miss Sullivan, who succeeded in showing Helen that she loved her and wanted to help her. The child and her teacher became friends. They continued to be friends until the teacher's death, fifty years later.

    The day on which Helen finally accepted Miss Sullivan as her friend and teacher was a great day in Helen's life. After that, the teacher could begin to teach the child language.

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability(可持续性)

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.
