问答题材料一：在一次偶然的课堂上，我正带领学生复习动能势能之间的相互转化时，忽然间从外面飞进一只黑色的燕子，容不得我半点的思考，顷刻间，教室炸开了锅，立刻沸腾起来，“怎么办？”看着他们的神情，看着燕子不停地上下穿梭，不停地煽动翅膀，我灵机一动，对着这些可爱的学生以及这个不速之客，说：“请同学们仔细观察我们的实验，看看它在运动过程中，有什么能量转化？还有哪些物理知识？”“什么，老师，您？”正在诧异的同时，燕子终于找到了通路，飞向了外面的世界。他们用自己的大脑回顾着刚才眼睛所看到的“实验”，争先恐后地回答：燕子在向上飞时，动能减少，势能增加；在向下飞时，动能增加，势能减少，它不停地煽动翅膀可能跟频率有关，也可能与力的平衡有关……材料二：在“运动的描述”中有几个基本的概念--运动、静止、位置、参照物，对于枯燥的概念，我们可以创设如下问题情境：教师引入“满眼风波多闪烁，看山恰似走来迎。仔细看山山不动--是船行。”营造诗情画意的氛围，从而提出：“是山动还是船行？”诗人为什么会产生如此矛盾的感觉？如果诗人置身于“满眼风波多闪烁”的意境中时，他忘记了自己是在随水流而前进的船上，仿佛看到了对面的山朝他走来；当诗人又感到“山没动，是船行”时，又是什么样的状况呢？根据上述材料，回答下列问题：（1）结合案例，谈谈初中物理教学中创设问题情境的重要性。（2）对第二则材料进行点评。

问答题伍老师在初中二年级上一节教学内容是立定跳远的体育课。刚开始伍老师采用了传统的集体练习模式，可刚练不到3组，就有学生反映："伍老师，太累了……，很没劲的……！"还有的说："……太单调了……！"听到这些话伍老师立刻想到：对呀！这又不是运动队训练，应该改变一下方法。然后就对学生说："那么，我们改变一下方法好吗？"听到伍老师的话，绝大多数学生都表示赞成。之后，伍老师就把学生分成了五组（异质分组），每组安排水平较高的学生任组长，而且要求各小组在组长的带领下通过尝试性练习一讨论-练习，一定要发挥小组团结协作的精神。通过练习，效果确实不同，气氛很热烈，许多原来成绩较差的学生最后都能有8~15cm不同层次的提高。而且，技术水平也有了明显提高。课后，还有学生问："伍老师，下次课我们还可以这样上吗？"（1）伍老师一开始采用的教学方法，为什么不受学生欢迎？（2）改变教学方法后教学效果显著提高，这是为什么？

单选题Passage 2For Chen Hua，28，an automobile engineer in Shanghai，reading out English text aloud after taking pronunciation lessons on a mobile app has become an evening routine. Chen might skip dinner，but wouldn't trade even one language class delivered by the app for anything.Not having been using English much since leaving college，Chen feels the pressure to pick it up using spare time. Thepressurearises from a constant fear of being left behind as English-proficient peers appear to get ahead. Academic circles refer to this as middle-class anxiety，which is grasping some sections of China's population.In a report released by leading online recruiter Zhaopin in January，one-fourth of surveyed white-collar workers said they feel more stressed than inspired，citing reasons from unstable paychecks to gloomy career prospects. Most important of all many people worry that the worth and utility of their knowledge and qualifications could erode due to thriving technological progress，globalism and entrepreneurship.Intensified peer pressure, especially at workplaces, is one factor that fuels our business,said Wang Yi, CEO of Liulishuo, an English-learning app that Chen uses every day. Wang,a Princeton computer science graduate and former product manager at Google Inc, launched the app over five years ago with the intention to disrupt China's hidebound brick-and-mortar language schools.Liulishuo-it is Chinese forspeaking fluently-brings social media and gaming elements to the genre. Wang said that unlike pre-school or K12 education, the adult-learning market is characterized by an inherent desire for self-improvement. Students of online adult education courses feel the fee is money well spent.To personalize offerings, Liulishuo has introduced big data and algorithms to quantify multiple dimensions of speech, as well as automatically tailor courses so that the courses could walk a fine line between challenging the students and discouraging them to the extent that they quit learning.Actually, this is not just confined to language courses. China's growing learners have shown they will spend time on the right educational programs.What does the underlined wordmiddle-class anxietyin Paragraph 2 referto?AUsing mobile apps constantly.BBeing unable to use English frequently.CFeeling the pressure to pick up English.DWorrying about being surpassed by English-proficient peers.
