Larry Ritsema was out for an early morning jog around his neighborhood one day. On a quiet street, he began to feel weak. Suddenly, everything went black. Larry fell to the ground.

    Less than a minute later, Tom Alguire passed by on his bicycle. He caught sight of a man lying on the roadside, so he jumped off his bike and ran over. He recognized Larry immediately, because he had been Larry's doctor for nearly 20 years.

    Dr. Tom felt for a pulse (脉搏) at first. Finding none, he began to give Larry first aid. It wouldn't restart Larry's heart, but it would keep the blood flowing until someone else arrive d. Tom could only hope someone would come by soon, at around six o'clock in the morning on a holiday weekend. Tom couldn't stop pressing Larry's chest to run for help — Larry's brain cells would die without the blood. And Tom didn't have a cell phone with him.

    Soon, a car did drive by. But the driver ignored Tom's appeal for help. What was he going to do? Tom was very worried. Finally, another car came down the road, driven by Michael Saliot, a U.S. Coast Guard Officer. Michael wasn't one to pass up a chance to help a person in need. He quickly dialed 911.

   Doctors then found that Larry had suffered a heart attack and there were severe blockages in two of Larry's major arteries (动脉). Only the timely arrival of Dr. Tom saved his life.

   How did Dr. Tom happen to be bicycling that morning, down that quiet street? It turned out that as Tom rode, his bike chain fell off. He spent about eight minutes fitting it back; otherwise, he would have seen nothing of Larry's problem.

    People who are confident really seem to be naturally outstanding and just seem to do everything with more styles than others. {#blank#}1{#/blank#} It is a habit that everyone can develop in life. Try these simple tips to drill and build up your confidence:

1). Admit your shortcomings calmly.

    Do not try to flee from them or cover them. Face them bravely. {#blank#}2{#/blank#} Fight against them every day until the day when you could break away and conquer them.

2). Dress for self-confidence.

    {#blank#}3{#/blank#} And therefore pay attention to your dress, display your unique physical advantages and exhibit your best image. In addition, on formal occasions such as a business conference or a wedding ceremony, elegant dressing contributes to building your confidence.

3). {#blank#}4{#/blank#}

    You should break your routine that deals with the work passively. Concentrate your efforts immediately on overcoming it, because it will make your restless mind at ease and build your self-confidence.

4). Be positive.

    Feel pity neither on yourself nor on others. If you are used to hating and accusing yourself, others would tend to do that and believe it. Instead, you should speak positively about yourself, your progress, and your bright future. {#blank#}5{#/blank#}

    Susan was born as the ninth child in a Catholic family. She suffered from learning disabilities ever since her birth because of her mother's poor health.

    School was difficult for Susan and she was bullied because of her different behaviors. Her siblings, who were much older, had life experiences that were unknown to their little sister. From the time of her birth, Susan was a screamer. The only really safe place that she would use as a repeat was her bedroom. There she would hang posters of her musical idols on the wall and sing popular music into a hairbrush that she pretended was a microphone.

    One by one the siblings moved away from home and then Susan's father died. This left her alone with an aging mother and a cat. The siblings accused her mother of not expecting more out of Susan. She had seen many professionals and remembered hearing the word “borderline” but didn't know what it meant. She tried volunteer work. Her best state of mind, however, was found when she was singing and so she would regularly join others in karaoke or pubs where she could show her skills and receive appreciation from the crowd.

    When Susan announced at Christmas that she was planning to compete in the Britain's Got Talent contest, her siblings tried to discourage her. It was a wonder that she was even able to do the audition considering the troubles she faced just physically getting to the right place.

    “The Woman I Was Born to Be” is a beautiful story written in the simple but humorous voice of the author, Susan Boyle. She tells her story from birth to the present in an interesting and educational manner. The writing is supplemented by photos from her albums.

    I love this book! In fact, I read the whole thing in one day!

There is something in the stories that not only teaches the reader but also inspires us to reach for our dreams — no matter how impossible they may seem to be!

    Getting stitched(缝合)up by Dr. Robot may one day be reality. Scientists have created a robotic system which did just that in living animals without a real doctor pulling the strings. Much like engineers are designing self-driving cars, the medical research is part of a move toward autonomous surgical robots, removing the surgeon's hands from certain tasks that a machine might perform all by itself.

    Doctors wouldn't leave the bedside they're supposed to watch, plus they'd handle the rest of the surgery. In small tests using pigs, the robotic arm performed at least as well, and in some cases a bit better, as some competing surgeons in stitching together intestinal(肠的)tissue. “The purpose wasn't to replace surgeons,” said Dr. Kim who led the project. “If you have all intelligent tool that works with a surgeon, can it improve the outcome? That's what we have done.”

    If you've heard about machines like the popular Da Vinci system, you might think robots already are operating. Not really. Today many hospitals offer robot-assisted surgery, where surgeons use the machinery as tools that they control by hand, typically,to operate through tiny openings in the body. But robot-assisted surgery has been controversial, as some studies have shown it can bring higher costs without better outcomes.

    Kim's team at Children's Sheikh Zayed Institute invented the new STAR system—it stands for Smart Tissue Autonomous Robot—works sort of like a programmable sewing machine. They added sensors to help guide each stitch and tell how tightly to pull. But the approach wasn't perfect. In the living animals, the robot took much longer and made a few stitching mistakes while the surgeon sewing by hand made none. Kim said the robot can be sped up. Fie hopes to begin human studies in two or three years.

    Students in a college French class have helped fill the empty bookshelves of a very poor Haitian(海地的) school by writing 90 books. Although many children in Haiti speak Creole(克里奥尔语) at home, French is taught in classrooms and used by the government , and students are asked to know the language in order to get further education. Therefore, the class hoped to provide resources to help the young students learn French well.

    The project, called Little French Books, was headed up by Jennifer Shotwell, a French professor at Randolph-Macon College in Ashland, Virginia. Shotwell had visited Haiti with a group of students in 2013 to support a Haitian student and give books to a new library. Following the trip, Shotwell brought the experience back to her classroom.

    "My students have a chance to use the French language in a special way by writing children's books," Shotwell said. "Though some learners don't think they can produce much with a new language, my students are learning to express themselves and create entertaining stories that we finally share with disadvantaged children who are also learning French."

    Shotwell had sent French books to Haitian schools, but they were printed on cheap paper that could be easily broken. So she started a Kickstarter, which collected more than $1,000 to make books with durable covers.

    The books, which included stories about princesses, dinosaurs and exciting experiences, were given to the St.Gabriel's school in Lascahobas.

    "Each time a child gets into a new book, he will no doubt get new knowledge and new understanding. The Little French Books means a lot to our students, said Gardy Myrtil, a teacher at the school.

    Plastic sludge(污泥)and garbage is a disaster for the world's oceans. A film crew traveled the globe to document the rubbish. And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem. “Half of the waste actually sinks to the bottom, and that remains on the surface actually breaks down. ”

    The filmmakers found rubbish in ocean gyres, the circulating currents that trap large concentrations of pollution in the Atlantic, Indian, and Pacifc Oceans, home of what some have plastic. What we found was a plastic smog that spread throughout all the water. And in some parts of the oceans, scientists have found more plastic than plant. ”

    The pieces of the plastic garbage infect the food chain, sometimes visibly, and more so at the microscopic level, where the plastic particles interact with other pollutants. “There are heavy metals, medicines, industrial waste in the sea, while it acts like magnets(磁铁). These poisonous substances absorb on the plastic, and then when seafood absorbs the plastics, those poisonous substances enter the fatty tissues. ”To be consumed by other sea life and by people at last.

    China, Indonesia, the Philippines, Thailand and Vietnam are the worst plastic polluters. The United States, although a leader in recycling, is one of the world's 20 since it produces and consumes so much plastic. There are efforts around the world to address the problem, including at this newly opened recycling center in Lebanon(黎巴嫩). But Andersen says there is more that people can do. “Cut back on single-use plastics, straws, plastic cups, plastic water bottles, plastic bags and find alternatives like reusable materials.” She says healthy oceans are essential to our survival.
