The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:?

Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better.

人教版高中地理必修1第三章第一节自然界的水循环教案
浅层地下水是贮存于地表松散堆积物中的潜水。主要受降水、气温、蒸发等气象因素影响，有明显的季节变化与日变化，并与河水有相应补给关系，即河水高于潜水面时，河水补给地下水，反之地下水补给河流；深层地下水是长时间内渗入地下深入储存起来的，它缓慢地流出补给河流，受气象因素影响很小，通常只有年变化，季节变化已不明显。当然，一条河流的河水补给来源往往不是单一的，而是以某一种形式为主的混合补给形式，对流域自然条件复杂的大的河流来说尤其如此。我国长江上游地区除雨水、地下水外，高原高山上冰川、积雪在夏季融化也补给河流；东北地区的河流，由春季融化积雪补给，夏季则由雨水和地下水补给；西北内陆盆地除雨水外，夏季高山冰川、积雪融化成为河流的主要补给形式。我国季风地区，大部分河流以雨水补给为主，而冬季则由地下水补给。

【导入新课】一位在青藏高原上跋涉的旅行者，途中休息时从路边岩层中随手拿起一块小石 头玩赏时受小石子的纹路的吸引，他不禁仔细观瞧，吃惊地发现这竟是一个古代海洋生物化石！近年来，人们在台湾海 峡海底某些地方发现有古代森林的遗迹。这些发现告诉我们什么？ 【学生讨论回答】略。 【教师总结概括】地壳和宇宙间一切物质一样，处在不停的运动变化之中。那么地表千姿百态的形态是如何营造的呢？这就是我们这节课要解决的课题【板书】第四章：地表形态的塑造 第一节：营造地表形态的力量【提问】哪位同学能够例举营造地表形态的力量改变地表面貌的实例？ （学生讨论、回答问题。教师在副板书上一一记录。） 【过渡】营造地表形态的力量具体划分有很多种，但归纳起来看可以划分为两种，即内力作用和外力作用，首先我们来看一下内力作用．【板书】一、内力作用 【指导读书】请大家阅读教材Ｐ74第一段和案例1，思考：
人教版高中地理必修1自然地理环境的整体性教案
1．生产功能：合成有机物的能力2．平衡功能：使自然地理要素的性质保持稳定的能力【教师讲解】生产功能主要依赖于光合作用。在光合作用过程中，植物提供叶绿素，大气提供热量和二氧化碳，土壤及水圈、岩石圈提供水分及无机盐。光合作用通过物质和能量的交换，将生物、大气、水、土壤、岩石等地理要素统一在一起，在一定的条件下，生产出有机物。由此可见，生产功能是自然环境的整体功能而非单个地理要素的功能。大气本身不具有减缓二氧化碳增加的功能，但是，在自然地理环境中，通过各地理要素的相互作用，却能消除部分新增的二氧化碳的能力，既为自然地理环境的平衡功能。请大家阅读教材P94活动，利用平衡功能的原理，解释一定范围内各物种的数量基本恒定这一现象。【学生讨论回答】略。（可参考教参）【转折】自然地理环境各要素每时每刻都在演化，如我们熟知的气候变化、地貌变化等。各个要素的发展演化是统一的，一个要素的演化伴随着其他各个要素的演化。
人教版高中地理必修3地理环境对区域发展的影响教案
(1)下面列出的是我国南北方传统民居的差异，分析形成这些差异的自然原因：——北方民居正南正北的方位观比南方强；——北方民居的墙体严实厚重，南方民居的墙体轻薄；——从北到南，民居的屋顶坡度逐渐增大，房檐逐渐加宽，房屋进深和高度逐渐加大。(2)下面列出的是我国南北方城市住宅搂的差异，分析导致这些差异的自然原因：——如果不考虑地价、建筑材料等因素，建同等面积的住房，北方的建筑成本比南方高 ；——建同样高度的多幢楼房，北方楼房的南北间距比南方大。点拨：本活动要求学生了解由于地理环境的差异造成南北方建筑物特点的不同，并由此认识地理环境 差异对人们生活的影响。（1）比较而言，北方的冬季寒冷而漫长，南方的夏季湿热而漫长。为了在冬季充分利用太阳光照和热量，北方民居正南正北的方位观比南方强。北方民居的墙体严实厚重，利用在冬季保温御寒；南方民居的墙体轻薄，利于在夏季通风透气。从北到南，年降水量逐渐增大，民居的屋顶坡度也逐渐增大（利于排水） ；随着对保温要求的降低和对通风纳凉要求的提高，民居的屋檐逐渐加宽，房屋进深和高度逐渐加大。
