实验室内设置有四辆脚踏车，每逢下课同学们就会排队来骑脚踏车，因为骑车不仅可以健身，同时还可以发电供学校使用．装在自行车上的发电机工作时把____ 能转化成电能．同学们用如图实验装置探究发电机的工作原理，探究中有同学们提出了问题：“感应电流的大小会跟哪些因素有关呢？”

小明猜想：“可能跟磁场的方向有关．”

小华猜想：“可能跟导体切割磁感线运动的方向有关．”图是小明的实验装置，闭合开关后，铜棒ab、电流表、开关组成闭合电路．小明将实验中观察到的现象记录在表中．

（1）小明分析得出：闭合电路中的部分导体在磁场里做____ 时，导体中就会产生感应电流．

（2）比较实验次数2和3（或6和7）可知：在磁场方向一定时，感应电流的方向与____ 有关．

（3）比较实验次数2和6（或3和7）可知：____ ．

（4）此实验的研究方法有控制变量法和____ 法．

（5）针对这个实验小明进行了进一步的探究，他提出了“感应电流的大小可能与切割磁感线运动的速度有关”的猜想，请你写出验证小明猜想的主要步骤：____ ．

故事分析：材料一 世界著名的发明大王爱迪生，晚年变得骄傲自大，甚至对手下说:“你们不要像我建议什么，任何高明的建议也超越不了我的思维。”这样他就堵塞了智慧的源泉，丧失了前进的动力，也就不再有什么重大发明问世。
材料二 李华是一个性格开朗活泼的同学。在学校的一次单元测验中，她的成绩落在全班最后。这时，李华变成了另外一个人，认为自己太笨，不可能学好了，整天垂头丧气，性格也变得孤僻起来。

Soap operas from South Korea have been popular in China for more than twenty years now. So it is not the first time for the soap operas made in China to feel less popular. But this time, they are facing more difficulties, for The Heirs (继承者) and My Love from the Star (来自星星的你) really made a full success, which even attracted some top officials.

A senior official said he sometimes watched soap operas from South Korea, as well as House of Cards (纸牌屋), an American opera about politics (政治). These operas made both in South Korea and in America have a lot of lovers in China.

Many people agree that China's soap operas can't be much loved by most Chinese, because they are not as interesting and exciting as those operas from South Korea and America, such as My Love from the Star, a Korean love story between a time traveling professor and a famous movie star.

    However，Korean shows not only provide soap operas but also some programmings (综艺节目). Dad, Where Are We Going? is not an original (独创的)Chinese show. We learned it from South Korea although not many in China realize that fact.

Actually, China has a closer culture with South Korea. Shows from this neighbor seem to do better with their exciting stories on the Cinderella theme (灰姑娘主题). Yet they have created many popular shows whose stories tell there's no difference between men and women even though in their country men are certain to play a more important role.
