生1:加强对绿色食品的宣传和扶持力度。当前的形势迫切要求我们发展绿色食品,因为绿色食品是真正实现可持续发展的,做到了发展经济和环境保护相结合,而且有利于增进人民身体健康。但目前绿色食品在市场上难成气候,主要是宣传和扶持不够。生2:绿色食品对环境、生长过程、加工过程以及运输等过程都有很严格的要求,很多环境相对优良的地区都是边远落后地区,必须给予政策上的扶持和优惠,才能降低成本,市场发展前景才会更加广阔。活动与探究对当地绿色食品市场情况作调查并初步分析。活动的实施过程:1.确定调查研究的目标并制定调查研究的计划。市场调查要深入广大消费者,可以去市场上做调查,‘对象包括消费者和经营者。形式可以是问卷,也可以是现场采访。弄清楚被调查者对绿色食品的态度,是否了解食用绿色食品的意义,是否懂得鉴别绿色食品等。对象力求涉及各个年龄段,多种职业。2.对问卷调查进行整理、分析,得出结论。
3.作者为什么不直接描写人们看见东西呢?请同学们找出其中的细节描写,并说明有什么表达效果。答:侧面烘托,正是作者高明之处,这也是许多佳作常用之法。细节描写往往会成为事情的切入点和突破口,一篇佳作往往离不开一些细节描写,本文也不例外,有些细节描写耐人寻味,如:“德国人撤退时炸毁的布热金卡毒气室和焚尸炉废墟上,雏菊花在怒放。”“这是一个二十多岁的姑娘,长得丰满,可爱,皮肤细白,金发碧眼。她在温和地微笑着,似乎是为着一个美好而又隐秘的梦想而微笑。”4.句子赏析:“对另外一些人来说,这样一个事实使他们终生难忘:在德国人撤退时炸毁的布热金卡毒气室和焚尸炉废墟上,雏菊花在怒放。”明确:一边是戕害生命的毒气室和焚尸炉,一边是生机勃勃的生命,两种反差极大的事物摆在一起。表达了作者对纳粹的讽刺:纳粹的残暴终归阻止不了生命的进程。同时也表达了作者的控诉:生命的绽放是人世间最美好的事情,对生命的戕害是最恶劣的罪行。
《贫寒是福天道酬勤石智勇从挫折中奋起》也许是自幼的贫寒生活塑造了石智勇内向的性格,即使是胸挂金灿灿的奖牌接受全场观众欢呼,他的表情也是略显羞涩的。小时候吃不饱肚皮的经历让他至今在“最喜欢的东西”一栏还填写着“食物”二字,而“穷人的孩子早当家”的坚韧,却又是促成他今日辉煌的动力。中国举重队副总教练陈文斌赛后说道:“智勇这几年练得很苦,今天终于有了这样的成绩,这是天道酬勤的结果。石智勇的奥运会金牌是中国男举的一次突破,我们非常激动。”在希腊神话里,命运女神总是让英雄历经磨难。石智勇也不例外。四年前的悉尼奥运会前夕,他在一次训练中扭伤脚踝,失去了参赛机会。“当时我伤心极了,不敢看电视直播,我怕参赛的选手成绩太低了。高点我还好一点,自欺欺人一下说,哎呀好高,自己去了也拿不了冠军,要是低了,自己没去,失去冠军机会,心里痛啊。后来结果出来,也不怎么高,心里真难受。”
4、主旨 哪一联明确地点明全诗题旨?表达了作者的什么感情?试做分析 颈联。 菊花开在秋天,所以这 “ 丛菊 ” 回应了诗题中那个 “ 秋 ” 字。 “ 他日 ” 可以指过去也可以指未来,在这里是指过去。“丛菊两开”,指诗人于 765 年离开成都,原打算很快出峡,但这年留居云安,次年又留居夔州,见到丛菊开了两次,还未出峡,故对菊掉泪。秋菊两度盛开,使诗人再次洒下往日流过的眼泪。“开”字双关,一谓菊花开,又言泪眼随之开。此时他仍然滞留在他乡,他始终没有放弃回乡的打算。孤舟可以系住,使其不能泛诸中流,但诗人的心是系不住的。他的心早已越过江河,越过关山,飞到了长安。所以,一叶靠岸系绳的孤舟,始终都牵动着诗人的故园之思。这一联是全篇诗意所在。孤舟本来只能系住自己的行踪,却把诗人的思乡之心也牢牢地系住了,故见舟伤心,引出故园之思,表现出思乡之情的深沉浓烈和欲归不得的无奈与凄伤,为文章的主旨句。
5、弊端:(1)经济发展不均衡,片面发展重工业,使轻工业和农业长期处于落后状态;(2)对农民的剥夺太重,挫伤了农民的生产积极性;(3)长期执行指令性计划严重削弱了企业的生产自主权,不利于发挥企业的生产积极性,制约了苏联经济的可持续发展。(4)计划经济体制确立后,没有随着社会的变化进行调整,二战后逐渐僵化,丧失了自我完善的功能,成为苏联解体的重要因素。【合作探究】斯大林模式的评价及经验教训:积极:①使苏联迅速实现了 工业化②苏联经济实力的迅速增长,为反法西斯战争的胜利奠定了 物质基础 。消极:①政治:高度集权,破坏了 民主与法制 ; ②经济:优先发展重工业使 农业和轻工业长期处于落后状态,农民生产积极性不高;计划指令,压制了地方和企业的积极性,阻碍苏联经济的发展高度集中的计划经济体制,成为东欧剧变和苏联解体的重要原因。
Finally, after finishing the task above, the teacher is expected to instruct students to work in groups to finish the following project:Speaking ProjectWhat event or activity would you like to invite your friend to?

Let’s listen and find out:Play the listening and match each opinion with the right speaker. Who do you agree with? Why?Cao Jing _____________ Lily _____________ Max _____________A. An athlete should do his/her best to win.B. The girl should stop and help the other girl. Good sportsmanship is more important than wining!C. An athlete should think about honor and his/her fans if he/she is competing for his/her country.Listen again and circle the expressions that you hear in the conversation.
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

How do you know?From their wearings, we can know they are from ethnic minority of China--- Miao and Dong.Picture 1, they are playing their traditional instrument lusheng in their traditional costumes.Picture 2. the girls are Miao because they wear their traditional costumes and silver accessory.2. In Picture 3, can you find which village it is? What time is it in the picture?It is Dong village. It is at night. Step 2 While-listeningJustin met a new friend while traveling in Guizhou. Listen to their conversation and complete the summaries below.Part 1Justin and Wu Yue watched some Miao people play the lusheng. The instrument has a history of over 3,000 years and it is even mentioned in the oldest collection of Chinese poetry. Then they watched the lusheng dance. Justin wanted to buy some hand-made silver/traditional accessories as souvenirs. He was told that the price will depend on the percentage of silver. Part 2They will go to a pretty Dong minority village called Zhaoxing. they will see the drum towers and the wind and rain bridges. They may also see a performance of the Grand Song of the Dong people.Step 3 Post-listening---TalkingWork in groups. Imagine Justin is telling some friends about his trip to Guizhou. One of you is Justin and the rest of you are his friends. Ask Justin questions about his trip and experience. The following expressions may help you.
4.They were going to find someone to take part in their bet when they saw Henry walking on the street outside.[归纳]1.过去将来时的基本构成和用法过去将来时由“would+动词原形”构成,主要表示从过去某一时间来看将要发生的动作(尤其用于宾语从句中),还可以表示过去的动作习惯或倾向。Jeff knew he would be tired the next day.He promised that he would not open the letter until 2 o'clock.She said that she wouldn't do that again.2.表示过去将来时的其他表达法(1)was/were going to+动词原形:该结构有两个主要用法,一是表示过去的打算,二是表示在过去看来有迹象表明将要发生某事。I thought it was going to rain.(2)was/were to+动词原形:主要表示过去按计划或安排要做的事情。She said she was to get married next month.(3)was/were about to+动词原形:表示在过去看来即将要发生的动作,由于本身已含有“即将”的意味,所以不再与表示具体的将来时间状语连用。I was about to go to bed when the phone rang.(4)was/were+现在分词:表示在过去看来即将发生的动作,通常可用于该结构中的动词是come,go,leave,arrive,begin,start,stop,close,open,die,join,borrow,buy等瞬间动词。Jack said he was leaving tomorrow.

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。
答案:铜车马的辉煌,来自原料的精挑细选、工艺的精巧极致和工匠的精心雕琢。可以说,是精益求精的工匠精神锻造出了“青铜之冠”的铜车马。2.“工匠精神”如此重要,那么,你认为“工匠精神”有着怎样的现实意义?观点一:工匠精神在企业层面,可以认为是企业精神。具体而言,表现在以下几个方面。第一,创新是企业不断发展的精神内核。第二,敬业是企业领导者精神的动力。第三,执着是企业走得长久的底气。改革开放40 多年来,我国涌现出大批有工匠精神的企业,但也有一些企业缺乏企业精神,只追求“短平快”的经济效益。这正是经济发展的隐忧所在。观点二:工匠精神在员工层面,就是一-种认真精神、敬业精神。其核心是: 不仅仅把工作当作赚钱养家糊口的工具,而是树立起对职业敬畏、对工作执着、对产品负责的态度,极度注重细节,不断追求完美和极致,给客户无可挑剔的体验。我国制造业存在大而不强、产品档次整体不高、自主创新能力较弱等现象,多少与工匠精神稀缺、“差不多精神”有关。

一、情境导学我国著名数学家吴文俊先生在《数学教育现代化问题》中指出:“数学研究数量关系与空间形式,简单讲就是形与数,欧几里得几何体系的特点是排除了数量关系,对于研究空间形式,你要真正的‘腾飞’,不通过数量关系,我想不出有什么好的办法…….”吴文俊先生明确地指出中学几何的“腾飞”是“数量化”,也就是坐标系的引入,使得几何问题“代数化”,为了使得空间几何“代数化”,我们引入了坐标及其运算.二、探究新知一、空间直角坐标系与坐标表示1.空间直角坐标系在空间选定一点O和一个单位正交基底{i,j,k},以点O为原点,分别以i,j,k的方向为正方向、以它们的长为单位长度建立三条数轴:x轴、y轴、z轴,它们都叫做坐标轴.这时我们就建立了一个空间直角坐标系Oxyz,O叫做原点,i,j,k都叫做坐标向量,通过每两个坐标轴的平面叫做坐标平面,分别称为Oxy平面,Oyz平面,Ozx平面.

本节课选自《2019人教A版高中数学选择性必修第一册》第二章《直线和圆的方程》,本节课主要学习抛物线及其标准方程在经历了椭圆和双曲线的学习后再学习抛物线,是在学生原有认知的基础上从几何与代数两 个角度去认识抛物线.教材在抛物线的定义这个内容的安排上是:先从直观上认识抛物线,再从画法中提炼出抛物线的几何特征,由此抽象概括出抛物线的定义,最后是抛物线定义的简单应用.这样的安排不仅体现出《课程标准》中要求通过丰富的实例展开教学的理念,而且符合学生从具体到抽象的认知规律,有利于学生对概念的学习和理解.坐标法的教学贯穿了整个“圆锥曲线方程”一章,是学生应重点掌握的基本数学方法 运动变化和对立统一的思想观点在这节知识中得到了突出体现,我们必须充分利用好这部分教材进行教学
