Writing 1 With the start of new school, freshmen of Hendersonville High School in Nashville were excited to meet new classmates and teachers. Among them, however,15-year-old Sergio Peralta was feeling very nervous because his right hand had never fully formed since he was born. Going to a new school and being "different" were always scary. Sergio was particularly concerned with what his classmates would think of him. Sergio's parents had trained him to use his left hand from an early age. As he grew up, he was used to not using his right hand. He could write with his left one and do some things with special tricks or techniques. Despite this, on the first days of new school, Sergio always felt like hiding his underdeveloped right hand in his sleeve as if nobody would ever find out if he did so. It didn't take long for someone to learn Sergio's secret. Jeff Wilkins, the teacher of Sergio's engineering class, figured out that Sergio was missing part of his hand and decided to do something for the new student. Jeff had been leading a robotics project in the school and expert in 3D printing technology. Besides, he hoped to take advantage of this hands-on chance to help his robotics students learn more about engineering and how a robotic hand worked. So in his class, Jeff announced with great enthusiasm, "You're supposed to come up with new ideas and solve issues. Now Sergio needs a new hand, so we'll work together to build Sergio a robotic hand." His words fueled everyone's curiosity and creativity. For the next four weeks, Jeff and his class including Sergio worked on the project. After some precise measurements and researches, the class put forward a design draft. Jeff made a few adjustments and gave them some practical suggestions. With access to online models and a 3D printer, they eventually created a robotic hand, which was intended to look good and work well, like catching something. 注意:1.续写词数应为150左右; 2.请按如下格式作答。 Then came the final testing day. The life-changing gift for Sergio drew huge attention. Writing 2 Melati and Isabel deeply love their home on the island, surrounded by tropical rain forests, green fields, and a vast ocean. Enjoying a swim in the waters was once a daily pleasure for them. But when Melati was fifteen, and Isabel just ten, the sisters started to lose their enthusiasm for swimming in the waters near their home. More often than not, plastic bags would be around them as they swam and some were scattered on the beach. They got really upset about that. Melati didn't think much about it until one day her teacher gave a lesson on some world heroes. Each of those people had sparked movements of positive changes in the world. They believed in the impact they could have and they did inspire more people to do something meaningful. After school, Melati walked home slowly in silence, concerned about the vast amount of plastic rubbish on the beach. The heroes crossed her mind. "If they could do it, we could ... ...
