Hadi Partovi，founder of Code.org believes every student should learn the basics of computer science just like they do math，physics，or biology，regardless of what they want to do in the future.The expert says knowledge about the subject is important to understand how the world around us works and compares it to learning about photosynthesis(光合作用)，even though not every student is going to be a botanist.To spark students’interest，he created the“Hour of Code，”which introduces the world of computing to anyone，from ages 14 to 104，in a fun，interactive manner.Observed annually during Computer Science Week，the event now draws tens of millions of kids from over 180 countries.
The“Hour of Code”，which can be scheduled anytime during Computer Science Week，begins with an introductory video on computer science.Participants can then select from hundreds of fun assignments that are sorted by both grade level and coding experience.Though each project is designed to last just sixty minutes，beginners can deal with as many challenges as they desire.
To help introduce computer science in classrooms on a more regular basis，Code.org has also developed a catalog of online courses that can be incorporated(纳入)in a school’s regular curriculum.Since the nonprofit began offering the courses in 2013，over 704，000 teachers have signed up to teach introductory computer science to over 22 million students worldwide.
Thanks to the efforts of the pioneer，about 40 percent of US schools now offer computer science as a subject.The numbers are even higher—an impressive 70 percent—if after-school offerings such as robotics clubs are included.Even more encouraging，eight years ago，just 19，390 students took an Advanced Placement Computer Science exam.By the spring of 2017，the number had jumped 415 percent to 99，868.

A crew of six teenage girls completed a nine-day sailing trip in the US recently，after braving seasickness and strong winds.
For the past three years，the Sea Cadet teenagers who set sail were all male.Roger Noakes，who captained the boat，said this was the first time he’d taken out an all-female crew.
The girls asked for an a11-girls trip in August this year.The crew set sail along with three adults，Noakes and two Sea Cadet representatives.The original plan was for the girls to sail 24 hours a day in rotating shifts(轮流换班)along the coast and then return.Things turned out differently，however. “The first night was rough because the wind was really hard.The waves were going up and down，”said Abby Fairchild，16.“Everybody got seasick.”Noakes gave the girls the option of just sailing in the bay and not going into open water.“But they decided they were going.”
The teenagers then sailed a long way overnight and slept in shifts.“We’ve learned everything from steering(掌舵)the boat itself to putting up the sails to cooking while we have rough seas，”said 15-year-old Olivia Wilcox.
The teenagers stopped on land in Massachusetts.They didn’t make it to their original destination in Maine，where they were supposed to have a celebratory dinner，due to the weather and winds.They said they weren’t disappointed，however，as they’d learned a lot.“They learned about boating，and above all，they built confidence and character，”said Noakes.
