B
Flow State
People enter a flow state when deeply focused on an activity that matches their skills in terms of difficulty. This state helps improve skills and boost enjoyment.
In the 1960s, psychologist Mihaly Csikszentmihalyi found artists often fell into this state when creating. His research showed flow happens during chess, surfing, surgery, writing and more—time feels faster in this state. He named it "flow state" because people said it felt like "being in flow".
Csikszentmihalyi explained flow comes from full participation in any activity, work or play. It is key to excellence and skill development. Challenges should be slightly beyond one's skills to keep the flow going.
Flow boosts performance and happiness, but it varies by person—some find it gardening, others drawing or running. The key is a beloved, enjoyable activity.
Also, the activity must be challenging enough to push skills. High challenges and high skills create flow, but the balance must be optimal. Too hard causes anxiety; too easy leads to boredom.
Noise breaks flow, so turning off phones helps achieve this state.

【分析】
本题为围绕“心流状态”的英语阅读理解题，包含细节理解、段落主旨、词义猜测、推理判断四类核心题型。解题时需先通读原文把握核心内容，再针对每道题的问题关键词回原文定位对应语句，将选项与原文信息逐一比对，排除矛盾、无中生有的错误选项，最终确定正确答案。
【解析】
19. 细节理解题：定位原文第一段“People enter a flow state when deeply focused on an activity...”，可知心流状态是深度专注于匹配自身技能难度的活动时进入的状态。
A项：原文提到“Noise breaks flow”，说明噪音会破坏心流，而非处于心流时吵闹，错误；
B项：原文第二段“time feels faster in this state”，说明时间感觉更快而非更慢，错误；
C项：与原文“deeply focused on an activity”表述一致，正确；
D项：原文未提及保护环境，属于无中生有，错误。
20. 段落主旨题：第三段核心内容为“Flow boosts performance and happiness...”，即心流状态的好处。
A项：研究历史在第二段提及，并非第三段内容，错误；
B项：第三段围绕心流的益处展开，正确；
C项：新挑战并非第三段主旨，错误；
D项：学习新技能的困难与第三段无关，错误。
21. 词义猜测题：定位第五段“High challenges and high skills create flow, but the balance must be optimal. Too hard causes anxiety; too easy leads to boredom.”，可知挑战与技能的平衡需处于合适状态，太硬焦虑、太易无聊，故“optimal”意为“最佳的”。
A项：“The best possible”（最佳的）符合语境，正确；
B、C、D项均不符合语境，错误。
22. 推理判断题：定位第五段“High challenges and high skills create flow”，结合原文信息判断作者观点。
A项：原文提到“Too hard causes anxiety”，焦虑是挑战过高的结果，并非有助于进入心流，错误；
B项：原文“too easy leads to boredom”，是挑战太易时无聊，而非太高，错误；
C项：原文“Noise breaks flow”，说明噪音环境无法进入心流，并非所有环境，错误；
D项：与第五段“High challenges and high skills create flow”表述一致，正确。
