| One day the wind said to the sun, "Look
at that man walking along the road. I can get his coat off more quickly than you
can." "We will see about that," said the sun. "I will let you try first." So the wind tried to make the man take off his coat. He blew and blew, but the man only pulled his coat more closely around himself. "I give up," said the wind at last. "I cannot get his coat off." Then the sun tried. He shone as hard as he could. The man soon became hot and took off his coat. |
| The day was like any other day in his
life, Tom walked past the shop on the street corner. He stopped to look at the
front row of shoes, and he felt happy to see that the pair of shoes he wanted
very much were still there. Looking down, he felt sorry for himself. He really
wanted to have them for his birthday. He sadly walked away and thought how to tell his mother about it. He knew she would give him anything he liked if she could. But he also knew very well she had little money. He decided not to go home at once (立刻) because he didn’t want his mother to be worded about him. So he went to the park and sat on the grass. Then he saw a boy in a wheel chair (轮椅), He noticed (注意到) that the boy moved the wheel with his hands. Tom looked at his own feet, "It’s much better than being without (没有) feet. "He thou [简答题]
阅读下面初中信息技术教学导入片段，回答问题。某初中信息技术教师在讲述计算机的文字处理时，这样导入新课："同学们，上节课，我介绍了Word文档的基本操作，如创建文档、打开文档、保存文档、文字输入等内容，这节课我们要在此基础上，学习根据文档的不同需求进行简单的排版。通过本课的学习，将使我们了解文档调整字体、行距及其他格式等知识，利用这些技能，使得我们的文档变得更规范、更美观。" [简答题]阅读以下材料，回答问题。材料：以下是教师在"通过激素的调节"教学过程片段：师：你还记得我们初中学习过的几种激素吗？这些激素分别是由什么器官分泌的？有什么功能？（投影教材中图2-8，要求学生归纳介绍人体主要的内分泌腺及其分泌的激素。）师：激素对人体的生命活动具有重要的调节作用。激素是怎样调节生命活动的呢？我们先讨论一下生活中熟悉的例子：工厂生产某种产品时对其产量是怎样进行调节和控制的？（师生共同讨论分析，教师归纳。）师：人体中的激素是如何进行反馈调节的呢？我们来分析两个实例，第一个是血糖平衡的调节。（1）在初中我们学习过哪种激素能影响血糖的含量？（2）胰岛素对血糖含量有什么影响？生：除了胰岛素外，胰高血糖素也与血糖的调节密切相关。（师投影胰岛细胞图片，示胰岛A细胞和胰岛B细胞，说明它们所分泌的激素，让学生猜测一下胰高血糖素的作用并作简要归纳。）引入活动：胰岛素和胰高血糖素是如何调节血糖的平衡的呢？先请同学们阅读课本"建立血糖调节的模型"的活动介绍，然后四人为一组，组内讨论交流设计出模型，并共同思考"分析与讨论"里的问题：（1）马拉松运动中，胰岛是怎样进行分泌调节的？饭后胰岛又是怎样进行分泌调节的？（2）当身体不能产生足够的胰岛素时，将会发生什么情况？当身体产生的胰岛素过多时，又会怎么样呢？（3）现在市场上有一种为糖尿病病人设计的人工胰岛素，可以随身携带，用以调节患者体内的血糖浓度。你觉得这种人工胰岛素设计的时候要考虑哪些主要的问题？（分组活动结束后，请各小组代表交流模型构建的过程和结果，在黑板上绘图或用实物投影，展示小组绘制的血糖调节机制示意图。并共同分析交流以上讨论题。）根据材料回答：（1）本材料运用了合作学习的教学策略，谈谈合作学习的含义。（2）简述合作学习的原则。
