1) It’s true that high-school coding classes aren’t essential for learning computer science in college. Students without experience can catch up after a few introductory courses, said Tom Cortina, the assistant dean at Carnegie Mellon’s School of Computer Science.
2) However, Cortina said, early exposure is beneficial. When younger kids learn computer science, they learn that it’s not just a confusing, endless string of letters and numbers — but a tool to build apps, or create artwork, or test hypotheses. It’s not as hard for them to transform their thought processes as it is for older students. Breaking down problems into bite-sized chunks and using code to solve them becomes normal. Giving more children this training could increase the number of people interested in the field and help fill the jobs gap, Cortina said.
3) Students also benefit from learning something about coding before they get to college, where introductory computer-science classes are packed to the brim, which can drive the less-experienced or-determined students away.
4) The Flatiron School, where people pay to learn programming, started as one of the many coding bootcamps that’s become popular for adults looking for a career change. The high-schoolers get the same curriculum, but “we try to gear lessons toward things they’re interested in,” said Victoria Friedman, an instructor. For instance, one of the apps the students are developing suggests movies based on your mood.
5) The students in the Flatiron class probably won’t drop out of high school and build the next Facebook. Programming languages have a quick turnover, so the “Ruby on Rails” language they learned may not even be relevant by the time they enter the job market. But the skills they learn — how to think logically through a problem and organize the results — apply to any coding language, said Deborah Seehorn, an education consultant for the state of North Carolina.
6) Indeed, the Flatiron students might not go into IT at all. But creating a future army of coders is not the sole purpose of the classes. These kids are going to be surrounded by computers — in their pockets, in their offices, in their homes — for the rest of their lives. The younger they learn how computers think, how to coax the machine into producing what they want — the earlier they learn that they have the power to do that — the better.
21. Cortina holds that early exposure to computer science makes it easier to____.
[A] complete future job training
[B] remodel the way of thinking
[C] formulate logical hypotheses
[D] perfect artwork production
22. In delivering lessons for high-schoolers, Flatiron has considered their____.
[C] career prospects
[D] academic backgrounds
23. Deborah Seehorn believes that the skills learned at Flatiron will____.
[A] help students learn other computer languages
[B] have to be upgraded when new technologies come
[C] need improving when students look for jobs
[D] enable students to make big quick money
24. According to the last paragraph, Flatiron students are expected to____.
[A] bring forth innovative computer technologies
[B] stay longer in the information technology industry
[C] become better prepared for the digitalized world
[D] compete with a future army of programmers
25. The word “coax” (Para.6) is closest in meaning to____.
根据题干关键同Cortina, early exposure to computer science 定位到第二段，③旬承接②句，继续说明年龄较小的孩子学习计算机的情况他们改变思维过程不会像大龄学生那样难:也就是说，年少时接触计算机科学比成年后才学习计算机更易于改变思维方式，因此[B]正确。
根据关键词“coax"定位到第六段④句。The younger they learn... the better ( 他们越早学习...就越好)重述全文主旨:让青少年提早学习计算机编码知识很有益处;而由全文可知，让青少年学习计算机编码知识的目的在于利用计算机处理实际问题，也即使用编码语言和计算机对话,向其发出命令，从而开发各种应用(如第四段未句所提的app)以满足生活需求，只有[A]符合这一内容。
