72-year-old Darlene Mullins recently graduated from Tennessee State University in Nashville, Tennessee. Darlene left school nearly 55 years ago in the name of love. She was studying at the college and met her husband-to-be, John Mullins, in 1962. The two knew they would marry each other the moment they met. She finished her freshman year with 25 credits and married John in 1963. Her husband graduated in 1964 and began working.

    Darlene took care of the household and was a stay-at-home mother to their son and daughter. The family lived in six states over the years, due to John's successful career in business. Darlene eventually began a career in retail as their children grew older. Though she remained busy, she always longed to finish school. She always told her children to make sure they finish what they started and she kind of felt it was time to live up to her own dream.

    John was very supportive when she told him she was going back to school. He knew the day would come when she decided to finish her degree. He told her whenever she was ready they would go. The couple moved back to Nashville in 2013 when Darlene re-enrolled. She had to adjust to the technological advances in the classroom, saying that she was determined to finish no matter how long it took. After completing four years, Darlene graduated with a degree, “I feel like God has given me a second chance.” she said' She hopes that her story can inspire others to pursue a degree.

    In the kitchen of my mother's houses there has always been a wooden stand (木架)with a small notepad(记事本)and a hole for a pencil.

    I'm looking for paper on which to note down the name of a book I am recommending to my mother. Over forty years since my earliest memories of the kitchen pad and pencil, five houses later, the current paper and pencil look the same as they always did. Surely it can't be the same pencil. The pad is more modern, but the wooden stand is definitely the original one.

    "I'm just amazed you still have the same stand for holding the pad and pencil after all these year." I say to her, walking back into the living-room with a sheet of paper and the pencil. "You still use a pencil. Can't you afford a pen?"

    My mother replies a little sharply. "It works perfectly well. I've always kept the stand in the kitchen. I never knew when I might want to note down an idea, and I was always in the kitchen in those days."

    Immediately I can picture her, hair wild, blue housecoat covered in flour, a wooden spoon in one hand, the pencil in the other, her mouth moving silently. My mother smiles and says, "One day I was cooking and watching baby Pauline, and I had a brilliant thought, but the stand was empty. One of the children must have taken the paper. So I just picked up the breadboard and wrote it all down on the back. It turned out to be a real breakthrough for solving the mathematical problem I was working on."

    This story—which happened before I was born—reminds me how extraordinary my mother was, and is, as a gifted mathematician. I feel embarrassed that I complain about not having enough child-free time to work. Later, when my mother is in the bathroom, I go into her kitchen and turn over the breadboards. Sure enough, on the back of the smallest one, are some penciled marks I recognize as mathematics. Those symbols have traveled unaffected through fifty years, rooted in the soil of a cheap wooden breadboard, invisible(看不到的)exhibits at every meal.

    When your dream is to become a footballer, nothing should get in your way—even if you have no feet.

    Gabriel Muniz, an 11-year-old Brazil kid, was born without feet. Although his family thought he would have serious difficulties living a normal life, he started walking before he was one year old. His mother would go after him, expecting him to keep falling, but he never fell. It took him a while to make the jump from walking to playing football, but he did make it. And, in fact, there's nothing he loves more than playing football. In his school, the skillful youngster (年轻人) is not only the best player in his school team but also the captain of his gym team.

    He knows that his disability means he'll never be able to play for a professional (专业的) football team. So Gabriel is hoping that football will one day become a Paralympics (残疾人奥运会的) sport. He proved to everyone there he could go head to head with any other boy. Watching him play is unbelievable. He's fast and he's got a big bag of tricks—he's very skilled and he does everything he can to copy his hero, Messi so much that he is invited to go to Spain to meet his hero Messi and show his talent in the Barcelona Football Club.

    His coach says he is proving the disability only exists (存在) inside our heads.

    I came to the United States ten years ago. I would always say that I was trying to study, but there were always things like work and my kids that would not allow me to start.

    Now I realized that those were only excuses. What stopped me was that I was afraid to start studying again. I always believed I would learn by myself.

    One day, however, my son told me that he was sad because his friends would come over and I didn't understand them because I didn't speak English. He was also sad because I could never help him with his homework. That same day, I told myself, "Rocio, you have to start believing in yourself and you will see you can make it."

    The next day, I went downtown to look for a big banner (横幅) in front of the school which said that they offered classes for adults. I came in to see if I could join, but the classes were closed already. That night I took the kids to the movies, and on the way back, I told them we would take a new route. I ended up getting lost. That's the way I found Chaffey College. The following Monday, I went to ask for information. They told me that summer school was starting that week.

    That's how I started studying English last summer. It is difficult, but I have had great rewards. My daughter had written a story for school. It was about the female they most admired and why. She wrote that I was the person she most admired because I had started going to college. I will never forget this.

    Are you interested in country music? I like it very much! It will take me away for a while after I am tired. The guitars and songs will take me to mountains and fields. Country music usually talks of everyday life and feelings. It's the spirit of America, easy to understand, slow and simple. Country music developed in the Southern United States. It was the folk music of American countryside. Many of songs tell about the lives of farmers. They talk about love, crops or death.

    The life of the countryside can be hard, so the words in country music are often sad. At first, people played the music only at family parties. But it became more popular later. In the 1920s, people played country songs on the radio, and they made them into records. When people in the countryside moved to towns and cities to look for work, they took their music with them. Country music continued to change and became popular across America. John Denver was one of America's most famous country singers in the 1970s. His song "Take Me home, Country Roads" is well-known and people still play it today.

Where does the meat on our table come from? It usually comes from livestock like chickens and cows. But did you know that meat can also be made in a lab? US company JUST has announced that lab-grown meat could be on some restaurant menus in the United States and Asia by the end of 2018, The Independent reported. 

"These meats include chicken nuggets (鸡块), sausage and foie gras (鹅肝酱), " Josh Tetrick, CEO of JUST, told The Independent. Lab meat is sometimes referred to as "clean meat". It is made using the stem cells (干细胞) of living livestock. The cells need to be grown in a lab for a few weeks. For example, making a hamburger patty (肉饼) takes about nine weeks, CNN reported. This is faster than raising a cow, which usually takes over 20 weeks. 

The first clean meat was a beef burger that was produced in 2013, but it was said to taste quite dry. How does clean meat taste now? Clean meat supporters told CNN that they think it tastes just like traditional meat. 

Clean meat has other advantages. It is healthier than traditional meat. Meat producers can control what type of fat goes into the meat. They can produce clean meat that contains healthy fats, such as omega-3 fatty acids (脂肪酸). This kind of fat is good for people's hearts. 

Clean meat can also help to solve global warming. According to The Washington Post, about 14. 5 percent of the planet's greenhouse gas emissions (排放) come from raising livestock. That's more than the emissions from every car, train, ship and airplane in the world combined. It is predicted that switching to clean meat could lower greenhouse gas emissions by 96 percent, The Independent reported.
