Roger Federer, a world-famous sports star, quit (放弃) the 2020 Olympic Games to deal with his knee problem. It was a hard decision because no one wanted to be a quitter. But finding the courage to let go can be good for you.
Nothing is fun all the time. Sticking at something difficult teaches us important skills like perseverance (毅力). However, learning to let go when things aren’t right is important too. Maybe your heart isn’t in playing the piano any more, or you only play football because your friends do and you want to try a different sport instead. Making the decision to walk away can free up time and energy to spend on something you really enjoy. In fact, studies show that letting go of goals you can’t reach, or don’t really want, can build up your confidence and help you lead a happier and healthier life.
But how can you know it’s time to stop and move on Eric Bean is an expert in sports psychology (心理学) who helps athletes and teams understand their feelings. He says, “Quitting is never a matter of black and white.” He suggests thinking carefully about why you aren’t enjoying something any more. Is it because you’ve argued with a teammate or can’t get on with a new art teacher Talk about this with a trusted adult or friend. That can help you decide whether you should stay and stick, or quit and move on.
Quitting doesn’t have to mean totally giving up, though. For example, playing an instrument might be more fun if you take away the pressure of exams. If you do decide to give up an activity, Bean suggests picking up another where you can still enjoy things like teamwork, creativity, and exercise.
( ) 1. The writer mentions “Roger Federer” in Paragraph 1 to show that ________.
A. we should never give up B. we should get away from trouble
C. it’s all right to stop and quit D. it’s difficult to win Olympic medals

专题3 从海水中获得的化学物质
第一单元 氯气及氯的化合物
课时1 氯气的发现与制备
1．实验室制备氯气时用如下操作，操作顺序正确的是(　　)
①连接好装置，检查装置的气密性
②缓慢加热，使气体均匀逸出
③在烧瓶中加入二氧化锰粉末


【小问2详解】
①高锰酸钾加热生成锰酸钾、二氧化锰和氧气，该反应的文字表达式为：；
高锰酸钾制氧气，根据文字表达式，符合“一变多”，所以是分解反应；
反应物为固体，反应条件需要加热，则发生装置为固体加热型，即选择装置A；氧气不易溶于水且不与水发生反应，因此收集较纯净的氧气用排水法，即用C装置，综上所述应选用的装置组合是AC；
②若用F装置(向上排空气法)收集氧气，氧气密度比空气略大，则气体应从a端进入
15. 分离空气可以获得稀有气体、纯度较高的氮气和液氧。分离空气的简易流程如图：
请根据流程图回答下列问题。
