活动准备:1.了解随地吐痰不仅会污染生活环境,而且还会危害身体健康。 图片(小朋友随地吐痰) 2.请小朋友回家向爸爸、妈妈咨询有关痰和病菌传播的危害。 活动过程:1.出示图片,引导幼儿观察: ▲图上的小朋友在干什么?这样做对吗?为什么? ▲使幼儿明白:我们不能随地吐痰,随地吐痰是不文明、不卫生的行为。 2.教师引导幼儿参与讨论: ▲在我们的痰里面,有什么? ▲你知道痰里面的病菌是怎样传播的? 鼓励幼儿大胆地谈谈痰传播疾病的途径。 3.教师小结:生病的病人身体内有很多的病菌,吐出的痰里也村有许多的病菌,这些闼如果被人踩了,就把细菌带到了各个地方;这些痰被太阳晒干了,痰里的病菌会跑道空气中,就会被吸入我们的身体内,传播各种病菌,危害人体的健康。
1.让幼儿在认识圆的基础上,通过做做、玩玩,让幼儿知道圆形的物体会滚动。2.知道用轮子能省力。3.发展幼儿的发散性思维。【活动准备】1.室外:(1)装有圆形轮胎的小三轮车、四轮车、小推车;(2)装有除圆形以外的各种形状轮胎的小三轮车、四轮车、小推车。2.室内:各种形状的小积木,幼儿人手一套;装有书籍的箱子一只,圆形的轮子两个,小推车一辆,大积木一块,每组一只盒子(装有橡皮泥、硬卡纸、彩色纸、剪刀、牙签、胶水、蜡笔)。【活动过程】一、第一次尝试:滚动圆形和其他形状构成的物体在室外供给幼儿装有圆形轮胎的小三轮车、四轮车、小推车以及装着除圆形以外的各种形状轮胎的小三轮车、四轮车、小推车。教师:“这里有许多车子,我们一起来玩一玩、想一想,哪些车子的轮子会滚动?”二、第二次尝试:圆形的东西会滚动1.在室内供给每位幼儿各种形状的积木玩。①你们的桌子上有什么形状的积木?②请你推动各种积木,你发现了什么?③为什么圆形的积木轻轻一推会滚,而梯形、正方形、长方形、三角形等的积木不会滚动呢?小结:圆形的东西会滚动,因为它没有角。
二、说活动家目标及重点难点1、理解故事情节,感受作品中清新的大自然画面。2、感受象声词,用语言正确地描述生活与自然的各种声音。3、丰富词汇,发展幼儿的观察力,思维能力和口语表达能力。本节课的重点是理解故事情节,难点是学习词语“手舞足蹈、惭愧、驮。”三、说活动准备1、课件制作2、场景布置:大树底下、山脚下、大海边、草原上。四、说教法:根据幼儿好奇、好问、好动、好模仿及具体形象思维占优势的特点,本次活动我主要采取以下几种教法。1、启发引导法:通过引导幼儿直观的观察,感知故事内容,并用递进式的提问,帮助幼儿理解故事。2、创设多媒体情景直观法:在活动中运用多媒体教学,符合幼儿爱看动画的特点。多媒体的声音,清晰美丽的画面,让孩子直接感知,从而更好的理解故事。五、说学法1、学观察:通过观看课件,把幼儿带入美丽、清新的大自然中,视觉与听觉的结合,使幼儿理解故事中的意境,感知自然界中的各种声响,调动幼儿的积极性,也激发了他们热爱大自然,热爱生活的情感。2、学思考:通过教师适当地提问,激发孩子们想象、思考、感受,发展幼儿的想象力。六、说活动过程:本次活动由三个环节构成,即“动――静――动”,这拉,有利于突破重难点,我是这样掌开教学思路的。1、激发兴趣(第一环节)活动开始,教师扮演松鼠妈妈,幼儿扮小松鼠,在欢快的音乐声中,“妈妈”带着孩子们在草地上玩片刻后回到房子里休息,妈妈问:“孩子们,我们住的房子会动吗?你见过会动的房子吗?可是,有一只松鼠宝宝却建造了一座会动的房子,这到底是怎么一回事呢?”我以这样的形式导入,目的是激发幼儿兴趣,带着疑问听故事。

你校英语报计划出版一期急救常识专刊,现面向全校学生公开征集稿件,你有意参加。请你根据下面提示内容,用英语写一篇短文,介绍在车祸现场对伤者进行急救的方法和步骤。1.确保现场的安全;2.询问伤者,确保其呼吸正常;3.检查伤口,如流血则应采取止血措施;4.如需急救,确保其处于康复位置。注意:1.词数80左右;2.可以适当增加细节,以使行文连贯。参考词汇:康复位置 recovery positionAs we all know, having a knowledge of first aid can make a great difference in our daily life. If a traffic accident happens and someone is injured, the following steps can be used to treat the injured.In the first place, we should make sure that the accident scene is safe so that we won’t get hurt. We should ask the injured person if he is OK, and see if he is breathing. What’s more, we should check for cuts and wounds. If he is bleeding badly, it is vital that we should try to stop the bleeding by applying pressure to the injury. This is because if a person loses too much blood, he may die. If necessary, take the injured person to the hospital as soon as possible.Do remember: when giving first aid, please be sure to place the person in a recovery position.
