新知讲授(一)——随机试验 我们把对随机现象的实现和对它的观察称为随机试验,简称试验,常用字母E表示。我们通常研究以下特点的随机试验:(1)试验可以在相同条件下重复进行;(2)试验的所有可能结果是明确可知的,并且不止一个;(3)每次试验总是恰好出现这些可能结果中的一个,但事先不确定出现哪个结果。新知讲授(二)——样本空间思考一:体育彩票摇奖时,将10个质地和大小完全相同、分别标号0,1,2,...,9的球放入摇奖器中,经过充分搅拌后摇出一个球,观察这个球的号码。这个随机试验共有多少个可能结果?如何表示这些结果?根据球的号码,共有10种可能结果。如果用m表示“摇出的球的号码为m”这一结果,那么所有可能结果可用集合表示{0,1,2,3,4,5,6,7,8,9}.我们把随机试验E的每个可能的基本结果称为样本点,全体样本点的集合称为试验E的样本空间。

一、指导思想:有信心、有耐心、有爱心 在德育工作中,班主任要尊重并相信学生的力量,要相信学生都有积极的一面。如果班主任不负责任地去埋怨或者是批评或者是惩罚一个学生,就是对他人格的极度不尊重和不信任,那样的结果是换来学生对你的不尊重和不理解,结果是班主任工作的极难开展。只有在了解的基础上充分的尊重和信任,才能限度的发挥学生的潜能。关爱学生是班主任开展工作的前提,只有关注学生才能了解学生,才能顺利、有效地开展德育工作。
鲜艳的五星红旗伴着雄壮的义勇军进行曲,在我们眼前冉冉升起,这预示着又一个充满希望的新学年开始了。借此机会,我代表学校向全体师生致以亲切的问候和美好的祝愿!下面是小编整理的关于高中校长国旗下讲话稿的内容,欢迎阅读借鉴。高中校长国旗下讲话稿范文1 同学们,老师们,大家上午好。20学习年就这样悄无声息地过去了,XX年也就这样悄无声息地来了。对于20XX年,我们xx在高考中取得了辉煌的成绩,让我们找回了xx昔日的雄心;对于20XX年,我们在新高一的招生中,取得了难得的好成绩,让我们找回了xx昔日的自信。对于20XX年,我想利用这次国旗下的讲话,和大家聊聊,对于我们xx的学子,应该以什么样的形象来面对20XX年,因为这一年是特殊的一年。同学们,今年是原xx一中高中部迁校重建二十周年,是xx市高级中学挂牌成立二十周年,你们准备以什么样的形象,来回报我们的学校,来回报我们的线校,来回报我们的大xx?你们为此又准备好了吗?
同学们:逢年过节,亲朋好友们总要祝福我心想事成。大多数人都认为这只是一个美好的祝愿,然而在我看来,这却是一个真理。因为,这并非无稽之谈。心想了才能够事成,前者是后者的必要条件,好比一座楼房如果事成是它的高度,那么心想便是它的地基,楼房的高度取决于心想的质量。我曾经看过这样一个故事,说有一位学生整天忙忙碌碌,读书做作业几乎达到废寝忘食,但一直不见任何成果。学生自己也很奇怪,于是请教一位德高望重的大师。看到大师正在悠闲的闭目养神,便问大师成功的奥秘到底是什么。大师开口问道:你每天在干什么?学生回答:我在学习。大师又问道除了学习还干什么?学生回答:还是学习。大师沉思片刻:那你什么时候思考呢?学生点了点头,似乎明白了其中的道理。
为大家收集整理了《高中升旗仪式国旗下讲话》供大家参考,希望对大家有所帮助!!!老师们、同学们:大家早上好!秋风送爽,桃李芬芳,在收获的金秋时节,今天我们迎来了第二十八个教师节,在此,让我以最简单却最温馨的方式道一声:老师们,教师节快乐!您辛苦了!多年来,通过高中一部全体教师的艰辛努力,高中一部传承了学生“勤奋、多思、 勇于探索”、教师“严谨、博学、敬业”的优良传统。先后培养出陈灿宇诸暨市文科状元、罗毅自主招生人被复旦大学提前录取优异成绩。 XX学年,在全体师生的共同努力下,在各级领导和社会各界的关心和支持下,高中一部的各项工作开展有序,成绩显著。高考喜获丰收、竞赛成绩喜人、高一、二会考成绩再创新高。XX年高考取得了优异的成绩,本届高三同学表现出色,一本上线人数22人,圆满完成学校下达的重点指标;本科上线190人,超额完成学校下达的本科指标,超指标35人。
步骤二 看图学单词我把本单元有关的单词制成图片显示在屏幕上。目的在于通过直观的画面效果和有意义的情景,便于学生更快地把单词的声、形和意联系起来。使学生轻松地掌握这些单词的音、形、义,且充分调动了学生的学习热情,让学生在思考中理解所学的生词。如 sitcom( situation comedy)1.猜。点击屏幕上一副有关情景喜剧的图片。说This is s kind of funny show. We call it sitcom. The people in sitcoms do or say things that make Tv watchers laugh.让学生根据图片和教师的提示猜出单词的意思。这时再告诉学生们sitcom=situation comedy.一定会有很多同学争先恐后地抢答,我们可以挑三个不同层次的学生起来回答,这样做既发挥了优等生的带头作用,同时为待优生树立起学好英语的信心,又增强了其他同学的竞争意识(他会我也会),也融入了教师的情感价值观之中。
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.
