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 engineer who was once a poor child himself,is bringing the charity's 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 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 is great for us,” said Assistant Pricipal 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.

    French writer Frantz Fanon once said: “To speak a language is to take on a world, a culture.” Since the world changes every day, so does our language.

     More than 300 new words and phrases have recently made it into the online Oxford Dictionary, and in one way or another they are all reflections of today's changing world.

    After a year that was politically unstable, it's not hard to understand the fact that people's political views are one of the main drives of our expanding vocabulary. One example is “clicktivism”, a compound of “click” and “activism”. It refers to “armchair activists” — people who support a political or social cause, but only show their support from behind a computer or smartphone. And “otherize” is a verb for “other” that means to alienate (使疏远) people who are different from ourselves — whether that be different skin color, religious belief or sexuality.

    Lifestyle is also changing our language. For example, “fitspiration” — a compound of fit and inspiration — refers to a person or thing that encourages one to exercise and stay fit and healthy.

    The phrase “climate refugee” — someone who is forced to leave their home due to climate change — reflects people's concern for the environment.

    According to Stevenson, social media was the main source for the new expressions. “People feel much freer to coin their own words these days,” he said.

    But still, not all newly-invented words get the chance to make their way into a mainstream (主流的) dictionary. If you want to create your own hit words, Angus Stevenson, Oxford Dictionaries head of content development, suggests that you should not only make sure that they are expressive (有表现力的) and meaningful, but also have an attractive sound so that people will enjoy saying them out loud.

    To be honest, I do not know Sybrina Fulton. Nor can I claim to understand the depth of her pain. Yet, we share a deep connection. A common feature experienced by those women who face the challenge of raising a Black male child in a nation that far too often views Black male bodies through fear. You see, Ms. Fulton is living my nightmare (噩梦). A constant worry that has stayed in the back of my mind since the birth of my eldest son, some sixteen years ago.

    Through the years, I have witnessed the world's reaction to my son evolve as he has grown from a small boy to a young man. In his early years, his easy smile and lovable character were nothing less than magnetic (有磁性的). Complete strangers would approach him in the street, draw him into conversation, and find themselves easily struck by his lively spirit. Even at that time I worried, how would my son react when in the years to come some of those who found themselves so impressed by this cute, intelligent boy, might grasp their purse tighter as he walked by.

    Over the years I have sought to protect his spirit from the hurt that comes from undeserved hatred. I have also sought to arm him with the knowledge that could one day save his life. He knows, for example, that if he is ever pulled over by the police, that he is to keep both hands on the wheel at all times and only reach for his license when the officer is specifically observing his actions. He knows, even in less threatening situations, that rough play and loud interactions with his buddies of any color will be viewed very differently when he does it, than when his white friends display the very same behavior. Still, the truth of the matter is, no amount of advice or voiceless behavior overcomes the physical, immovable fact of the color of his skin. His intelligence, easy smile, and lovable character won't protect him from unfounded assumptions of criminality.

    What makes the Trayvon Martin travesty (歪曲) of justice so painful to me, personally, is the knowledge that Trayvon's mother loved her baby no less than I love mine. The various pictures of moments throughout a happy childhood that have now found a home on nationwide newscasts provides clear evidence of that. Yet no amount of love and care, and no words of advice could have saved her son from the cruel killing he faced at the hands of a self-appointed neighborhood watch-dog. And perhaps even worse, nothing could have prepared her for the inhuman way her son has been treated by officials even in death. To think for three long days, his parents searched for him while officials failed to inform them of his fate and instead, performed drug and alcohol tests on his lifeless body, while failing to do the same for his attacker—the only one of the two who indeed had a criminal past is frankly, unforgivable. To know that the words of her son's killer were given more weight than eye-witnesses and taped evidence of her child's screams and eventual death must be heartbreaking. But to also have to live with the fact that his attacker still breathes free while her son lays buried underground is certainly more than any sorrowful parent should have to endure (忍受).

    It is this type of pain that is not unfamiliar to the Black experience in America, for this is the Black mothers' burden. A burden we have endured for centuries. Yet, there is still the rightful expectation, that in modern-day America, the wheels of justice would not be stopped.

    So today, it is my hope that Trayvon's mother, father, family and friends can take some comfort in the fact that millions of Americans of every color stand with them in their fight for justice. This is a burden no family should have to endure alone.

    We will not give up. We will not forget. We will continue the fight until justice is done.

    I've come back to check on a baby. Just after dusk I'm in a car down a muddy road in the rain, past rows of shackled(戴镣的) elephants, their trunks swinging. I was here five hours before， when the sun was high and hot and tourists were on elephants' backs.

    Walking now, I can barely see the path in the glow of my phone's flashlight. When the wooden fence post stops me short, I point my light down and follow a current of rainwater across the concrete floor until it washes up against three large, gray feet. A fourth foot twisted above the surface, tied tightly by a short chain and choked by ring of metal spikes(尖刺) When the elephant tires and puts her foot down， the spikes press deeper into her ankle.

    Meena is four years and two months old, still a child as elephants go. Khammon Kongkhaw, her caretaker, told me earlier that Meena wears the spiked chain because she tends to kick. Kongkhaw has been responsible for Meena here at Maetaman Elephant Adventure, near Chiang Mai, in northern Thailand, since she was 11 months old. He said he keeps her on the spiked chain only during the day and takes it off at night. But it's night now.

    I ask Jin Laoshen, the Maetaman worker accompany in me on this nighttime visit, why her chain is still on. He says he doesn't know.

    Mactaman is one of many animal attractions in and around tourist-crowded Chiang Mai. Meena's life is set to follow the same track as many of the roughly 3, 800 captive(被捕获的) elephants in Thailand. When Meena is too old or sick to give rides-maybe at 55, maybe at 75she'll die. If she's lucky, she'll get a few years of retirement. She'll spend most of her life on a chain.
