Moksh Jawa, 16, a student at Washington High School in the US, has already become a legend(传奇) among students. “Why not?” might be his favorite question to ask.

As a seventh-grader, he taught himself coding(编程) by studying on the Internet.

As a high school freshman, he passed the AP Computer Science A exam with a 5, the highest score possible.

As a sophomore (高中二年级学生), he developed his own online course and helped his classmates get through it because his high school didn't teach coding.

Everything he did came from his own interest. His father sent him a link to Codeacademy, an online coding training program, in middle school. He learned a programming(编程) language all by himself after signing up to the website.

“I just fell in love with computer science,” Jawa said. Along the way, he lit a fire of curiosity and passion among classmates to learn coding too.

“All of my friends, especially the girls, were really, really afraid of computer science,” he said. But the subject and exam weren't things to be feared, he said, “Computer science is all about logic(逻辑), not about how smart you are. ”

To make his knowledge available online, Jawa set about creating his own online course, with easy-to-follow lessons. He included quizzes and tests too.

The course has so far attracted 3, 200 students across the US and in 120 countries and regions, including China, Ukraine and Algeria.   It shows, Jawa said, the huge need for coding lessons.

When video lecturing, “I deliver it like I'm talking from one high school student to another .” Jawa said.“ It's always great to make it as clear and fun as possible, and to try to keep my voice as energetic as possible. ”

He also does that, when teaching members of the computer science club he founded at his high school.

“His tutorials(辅导) were great, ”said Taj Shaik, the club's co-president, who took the whole course last year. “I'm definitely one of the early adopters(使用者) of Moksh. ”

“He's pretty amazing, ”said Bob Moran, principal of Washington High School, who saw him lead the club. “He was just a fantastic teacher—clear, organized and entertaining. When a student got the right answer, he would throw him a candy. ”

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

Gabriel Muniz, an 1l–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 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 football team. So Gabriel is hoping that football will one day become a Paralympics(残疾人奥运会)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 was 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 and he is challenging the social rules.

Taking five days to complete a half-marathon (马拉松) may not seem impressive. But you change your mind when you learn the woman who did it is paralyzed (瘫痪的) from the chest down and 16 weeks pregnant.

Claire Lomas began the Great North Run, which is called half-marathon, in northeastern England on Wednesday morning. 36-year-old Lomas ran average 3 miles a day. She used a bionic (仿生学的) suit that helped her move and lift her legs during the marathon, according to the BBC. “It’s not just physical work. It’s the concentration with every step,” Claire Lomas said.

Claire Lomas was paralyzed from the chest down after a horseback riding accident in 2007. Despite the challenges she’s faced, Claire Lomas believes people with spinal (脊柱) injuries should stay as active as possible. Running a marathon is good for your health, anyway, whether you are an active person or not, she told the BBC.

Claire Lomas made the walk with the help of a bionic suit. It was purchased (购买) after she raised around $66,000. The suit uses a series of sensors (传感器) so users can control movement with their upper body. Claire Lomas had to use sticks for balance. Her husband Dan Smith helped out as well.

This isn’t the first time Claire Lomas has competed the Great North Run using the robotic exoskeleton (外骨骼). In 2012, she also walked the London marathon and finished in l6 days, according to the BBС.
