因为x3表示手机部数,只能为正整数,所以这种情况不合题意,应舍去.综上所述,商场共有两种进货方案.方案1:购甲型号手机30部,乙型号手机10部;方案2:购甲型号手机20部,丙型号手机20部.(2)方案1获利:120×30+80×10=4400(元);方案2获利:120×20+120×20=4800(元).所以,第二种进货方案获利最多.方法总结:仔细读题,找出相等关系.当用含未知数的式子表示相等关系的两边时,要注意不同型号的手机数量和单价要对应.三、板书设计增收节支问题分析解决列二元一次方程,组解决实际问题)增长率问题利润问题利用图表分析等量关系方案选择通过问题的解决使学生进一步认识数学与现实世界的密切联系,乐于接触生活环境中的数学信息,愿意参与数学话题的研讨,从中懂得数学的价值,逐步形成运用数学的意识;并且通过对问题的解决,培养学生合理优化的经济意识,增强他们的节约和有效合理利用资源的意识.

答:书包单价92元,随身听单价360元。最优化决策:聪明的Mike想了想回答正确后便同爸爸去买礼物,恰好赶上商家促销,人民商场所有商品打八折销售,家乐福全场购物满100元返购物券30元销售(不足100元不返券,购物券全场通用),但他只带了400元钱,如果他只在一家购买看中的这两样物品,你能帮助他选择在哪一家购买吗?若两家都可以选择,在哪一家购买更省钱?提示:书包单价92元,随身听单价360元。2)在人民商场购买随声听与书包各一样需花费现金452× =361.6(元)∵ 361.6<400 ∴可以选择在人民商场购买。在家乐福可先花现金360元购买随身听,再利用得到的90元返券,加上2元现金购买书包,共花现金360+2=362(元)。因为362<400,所以也可以选择在家乐福购买。因为362>361.6,所以在人民商场购买更省钱。第五环节:学习反思;(5分钟,学生思考回答,不足的地方教师补充和强调。)

1.根据课程标准的要求。本单元的主题是“生活智慧与时代精神”,课程标准的要求主要是引导学生“思考日常生活富有哲理的事例,感悟哲学是世界观的学问,能够开启人的智慧”,“解释哲学的基本问题”,“分析实例,说明真正的哲学是时代精神的精华,明确马克思主义哲学在人类认识史上的重要地位”。这些问题,综合起来就是使学生明确哲学与我们生活的关系,认识学习哲学特别是马克思主义哲学对我们人生的作用。因此,探究本问题有助于学生更好地理解本单元的内容,完成本单元的教学目标。2.根据学生的实际需要。学习哲学特别是马克思主义哲学,可以帮助学生树立正确的世界观、人生观和价值观,这也是学习哲学的主要目的。但在学生中还不同程度地存在着“哲学与我们的生活很远”、“哲学与我无关”、“哲学对我将来从事自然科学的研究没有什么用处”等认识,这些都影响着学生对哲学学习的态度和哲学作用的发挥。设置本探究问题,有助于帮助学生澄清这些模糊认识。

7.我国人力资源开发利用面临四大挑战在全面建设小康社会进程中,我国人力资源开发与利用面临着以下四个方面严峻挑战。(1)劳动力供给高峰的到来加剧了劳动力供求总量矛盾。持续的经济增长和人口计划生育控制,使得我国人口再生产在不到30年的时间内完成了从“高出生率、低死亡率、高自然增长率”的类型到“低出生率、低死亡率、低自然增长率”类型的转变,人口在日增长率已经连续数年低于千分之十。然而,庞大的人口基数及其低速增长仍对中国未来经济增长和社会发展带来巨大的就业压力,大量预测表明,未来20年是中国人口数量增长和劳动力供给的高峰时期。20世纪90年代以来,中国劳动年龄人口比重(16—59岁年龄组)由1990—1996年期间的61%~62%上升到1999年的63.2%。这种趋势将会持续到2020年左右达到峰值,直到老龄化进程抵消了数量增长效应,劳动年龄人口的比重才会趋于下降。到2020年,中国劳动年龄人口将由2000年的8.61亿上升到10.04亿,平均每年新增劳动力715万人。

一、教材分析人教版高中思想政治必修4生活与哲学第一单元第三课第二框题《哲学史上的伟大变革》。本框主要内容有马克思主义哲学的产生和它的基本特征、马克思主义的中国化的三大理论成果。学习本框内容对学生来讲,将有助于他们正确认识马克思主义,运用马克思主义中国化的理论成果,分析解决遇到的社会问题。具有很强的现实指导意义。二、学情分析高二学生已经具备了一定的历史知识,思维能力有一定提高,思想活跃,处于世界观、人生观形成时期,对一些社会现象能主动思考,但尚需正确加以引导,激发学生学习马克思主义哲学的兴趣。三、教学目标1.马克思主义哲学产生的阶级基础、自然科学基础和理论来源,马克思主义哲学的基本特征。2.通过对马克思主义哲学的产生和基本特征的学习,培养学生鉴别理论是非的能力,进而运用马克思主义哲学的基本观点分析和解决生活实践中的问题。3.实践的观点是马克思主义哲学的首要和基本的观点,培养学生在实践中分析问题和解决问题的能力,进而培养学生在实践活动中的科学探索精神和革命批判精神。

(2)这样的例子很多,如,有的同学利用自己掌握的计算机知识制造黑客程序,破坏校园网的正常运行;有的生产者和经营者制假售假,坑蒙拐骗;有的人身上存在着拜金主义倾向;等等。从上面的课堂探究中,我们认识到:(1)出现道德冲突的原因:生活变化很快,不断加快的城镇化进程;新型产业的崛起与传统产业的衰落,使众多劳动者不得不面对新的择业问题;网络的普及,使越来越多的人进入社会交行的新天地;等等。在急剧变化的社会生活中,人们在告别传统牛活方式的同时,也常常遭遇思想道德下的“两难选择”。(2)解决道德冲突的重要途径解决道德冲突的一个重要的途径,就是在社会主义精神文明建设的实践中,加强自身知识文化修养和思想道德修养,不断追求更高的思想道德目标。◇课堂练习:道德冲突()①是经济生活日益发展的反映②不存在于现实生活中③是一个永远无法解决的问题④是社会生活急剧变化的产物

三、宗教改革:1、背景:(1)文艺复兴的影响。文艺复兴中,人文主义学者尽管对宗教保持较为温和的态度,但其以人为中心的思想极大地冲击了天主教的精神独裁,天主教的权威日益受到人们的怀疑。(2)天主教会对欧洲尤其是德意志的压榨。中世纪的天主教会对人民进行严密的精神统治,基督教信仰的核心是“原罪”和“灵魂救赎”,即人生下来就有罪,只有信仰上帝,跟随耶稣才能得救。就“灵魂救赎”而言,最初强调的是个人信仰的作用,后来,神学家们又加上了种种繁杂的宗教礼仪,而且必须得到神职人员的帮助,灵魂才能得救。在经济上,天主教会还是最大的封建主,占有大量的土地,并征收什一税,对各国人民大肆搜刮。罗马教廷每年从德意志搜刮的财富达30万古尔登(货币单位),相当于“神圣罗马帝国”皇帝每年税收额的20倍。德意志也成了被教会榨取最严重的地区,素有“教皇的乳牛”之称。

The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2. Students can understand the past, the present situation of some festival around the world and why there are some changes about them.Step 1 Lead in---Small talkWhat festival do you like best ? Why ?I like the Spring Festivals because I can set off the fireworks, receive the lucky money and enjoy the Gala with my families.Step 2 Before reading---Pair workWhy do people celebrate different festivals ?The Spring Festivals is to celebrate the end of winter and the coming of spring and new life.The Mid-autumn Day is to celebrate the harvest and admire the moon.

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.
