岳麓版实验教科书必修(I)第1课夏商制度与西周封建山东省实验中学任杰【教学目标】1、课标要求:了解宗法制和分封制的基本内容,认识中国早期政治制度的特点。
2、三维目标:【教材分析】中国的历史是世界上唯一没有间断过的历史。
我们的祖国拥有五千年的灿烂文化。
早在夏商时期,我们的祖先就创立了一系列有利于国家统一的政策,建立了中国历史上最早的政权。
到了周朝,中华民族的先民们,创立了宗法分封制度等近乎理性科学的有利于国家统一的制度,并且将“国”和“家”结合在一起,成为中华民族政治统一和国民性组成的一部分。
本节课分为三部分内容“夏商政治制度”、“封邦建国”和“以嫡长子继承为核心的宗法制度”。
第一目重点在于让学生了解中华政治文明的源头——夏商政治制度。
第二目则介绍了西周的分封制,让学生明确先秦中国就有了较为科学的巩固国家统一的制度,在分析此目的时候可以初步培养学生的读图能力和材料分析能力。
第三目则阐明了宗法制,这一目学生掌握起来较有难度,里面涉及到很多新的概念“嫡长子继承”、“大宗小宗”和“贵族等级序列”等概念。
这一目应该作为难点进行处理。
【学情分析】本课的教学对象是刚进入高中的学生,他们依然是感性思维占主体,这部分内容学生多在平时生活和初中学习中几乎没有接触,因此需要让学生在掌握具体知识的基础上,更多地去理解先秦的政治制度。
本课能搜集的史料相对较多,也更为生动。
因此,可以多元化的开发各种立体的教学方法,以提高学生的分析、归纳和整理的能力。
【教学重点、难点】重点:西周分封制和宗法制度。
处理方法:通过多媒体创设情境,辅以文字资料、图片材料、视频资料等,运用史料分析,回顾历史等方法让学生分析分封制和宗法制。
以此让学生认识到祖国统一是有着历史的渊源的,从而增加学生对祖国统一的自信心。
难点:理解宗法制中的嫡长子继承制和大宗小宗的相对关系,以及宗法制对历史的影响。
处理方法:运动角色扮演、实例体会的方式,让学生亲身体会宗法制的运用和在现实生活中的体现。

While it’s painful to accept this, the new reality becomes normal for most of us as we face new academic, adult and job responsibilities.I’ve been dancing since I was four and I plan to continue dancing in college. However, I’ve always feared that dancing will affect my study and eventually become a brilliant memory of my childhood. After learning about Sommer Gentry’s story, I had an answer.Sommer Gentry, previously a professor of mathematics at the United States Naval Academy and a coach at the Naval Academy’s Swing Dance Club, is currently a teacher at NYU Grossman School of Medicine. Gentry and her husband also started a swing dance community to introduce non-dancers to swing dance.Through teaching, Gentry was inspired to view dancing from an engineering point of view. She said, “I realized it is an engineering question: how do you dance well with someone? It’d be great to give people mathematical and engineering proofs that they have to dance the way I say.” Gentry investigated the complex haptic (触觉的) communication behind the moves in swing dance and showed that two persons could move in coordination (协调) with pure haptic communication, She entered an exciting area of research which is about engineering, psychology and human motor control.It’s incredibly inspiring that Gentry was able to intertwine her academic work with her passion for dancing. Gentry said, “It means that even when I’m dancing outside, I’m thinking about my research project.”Gentry found that digging into her academic interest does not mean letting go of her other non-academic ones. Instead, she found a way to include both in her professional life.Just like me, Gentry is a mathematician and dancer, thus, her story resonates (引起共鸣) strongly with me, and I want to be like her in the future.54.What did the author think of dancing before learning of Gentry’s story?A.It was too challenging for her B.It’d gradually disappear from her life.C.It’d help develop her sense of responsibility.D.It brought her an unpleasantchildhood memory.55.What contributed to Gentry’s studying dancing from the angle of engineering?A.Her interest in exploring engineering proofs.B.Her husband’s need to promote his dance club.C.Her desire to be an expert in medicine and health.D.Her experience in teaching math and swing dance.56.What does the underlined word “intertwine” in Paragraph 5 probably mean?A.Hardly balance B.Carefully compare.C.Closely combine.D.Successfully challenge.57.What does the last paragraph imply about the author?A.She has decided to change her major.B.She will continue to pursue her hobby.C.She used to be Sommer Gentry’s student.D.She originally had little interest in engineering.When Malaika V az was a kid, living in Goa, India, she was constantly surrounded by nature. Among her childhood experiences, she recalls journeys to the Arctic and Antarctic, climbing mountains, diving, and windsurfing.At some point in her late teens, Vaz realized adventure didn’t really mean anything if there wasn’t an intention to protect the natural spaces we were exploring in. Motivated by her passion for filmmaking, she began to seek a way that would both satisfy her appetite for adventure and allow her to advocate the protection of the species and ecosystems she interacted with.Today Vaz wears many hats in the filmmaking world, as a documentary director, producer, and presenter. After falling in love with manta rays (蝠鲼), she discovered they were being hunted illegally and started to dress herself as a seafood trader to get as close as possible to the issue. She traced sellers to figure out why the threatened species were being killed. She shared the shocking details in Peng Yu Sai, her Green Oscar-nominated film on thematter.The subjects that grab her attention, Vaz admits, run the gamut. When she was asked to define her focus, she replied that she preferred variety. She always argues that the issues she looks into are more interrelated than they may initially appear. “I think that it’s exciting to dive into the different aspects of environmental stories,” she says.Her work doesn’t stop at recording important stories; she also ensures the message is heard. From Vaz’s viewpoint, real improvement in planetary protection lies in the hands of each of us rather than just those of several environmentalists. “If you’re an engineer and you care about the natural world, you can change the kind of construction materials you use. If you’re a teacher loving nature, you can bring that into the learning for your class.” she says.As a filmmaker, Vaz believes it’s important to figure out ways that attract the audience who can push for the protection of the natural world.58.What did Malaika V az decide to do in her late teens?A.Motivate children to get close to nature.B.Make a film about her childhood experiences.C.Develop a passion for an adventurous lifestyle.D.Combine nature exploration with nature conservation.59.What is the film Peng Y u Sai mainly about?A.The role of manta rays in the local economy.B.Vaz’s personal life as a seafood trader.C.The threatened species in India.D.The illegal trade in manta rays. 60.What does the underlined part “run the gamut” in Paragraph 4 probably mean?A.Are quite popular.B.Cover a wide range.C.Make little progress.D.Are hard to deal with.61.What message does the author convey in Paragraph 5?A.Human beings are closely linked to nature.B.Stories are effective in changing people’s behavior.C.Everyone can make a difference to the environment.D.Environmentalists play a big part in solving environmental issues.。

(1)求f (x )解析式;(2)判断并证明函数f (x )在区间(1,+∞)的单调性.解:(1)根据题意,函数f(x)=ax 2−b x,且f (﹣1)=﹣1,f (1)=3, 则有{a +b =−1a −b =3,解可得a =1,b =﹣2,则f (x )=x 2+2x ;(2)f (x )在区间(1,+∞)上递增,证明:设1<x 1<x 2,则f (x 1)﹣f (x 2)=(x 12+2x 1)﹣(x 22+2x 2)=(x 1﹣x 2)(x 1+x 2−2x 1x 2), 由于1<x 1<x 2,则x 1﹣x 2<0,x 1+x 2>2,x 1x 2>1,2x 1x 2<2, 则有f (x 1)﹣f (x 2)<0,故f (x )在区间(1,+∞)上递增.20.(12分)一家商店使用一架两臂不等长的天平称黄金,其中左臂长和右臂长之比为λ.一位顾客到店里购买10克黄金,售货员先将5g 的砝码放在天平左盘中,取出一些黄金放在天平右盘中使天平平衡;再将5g 砝码放在天平右盘中,然后取出一些黄金放在天平左盘中使天平平衡.最后将两次称得的黄金交给顾客,(1)试分析顾客购得的黄金是小于10g ,等于10g ,还是大于10g ?为什么?(2)如果售货员又将5g 的砝码放在天平左盘中,然后取出一些黄金放在天平右盘中使天平平衡,请问要使得三次黄金质量总和最小,商家应该将左臂长和右臂长之比λ设置为多少?请说明理由. 解:(1)由于天平两臂不等长,设天平左臂长为a ,右臂长为b ,且a ≠b ,先称得黄金为xg ,后称得黄金为yg ,则bx =5a ,ay =5b ,则x =5a b ,y =5b a ,所以x +y =5a b +5b a ≥2√5a b ⋅5b a =10, 当且仅当5a b =5b a ,即a =b 时取等号,由a ≠b ,所以x +y >10,顾客购得的黄金是大于10g ;(2)由(1)再一次将5g 的砝码放在天平左盘,再取黄金mg 放在右盘使之平衡,则此时有5a =bm ,此时有m =5a b , 所以三次黄金质量总和为:x +y +m =5a b +5b a +5a b =10a b +5b a ≥2√10a b ⋅5b a =10√2,当且仅当10a b =5b a ,即b =√2a 时取等号, ∴a b =√22=λ,所以三次黄金质量总和要最小,则左臂长和右臂长之比λ=√22.21.(12分)已知命题:“∀x ∈[﹣1,3],都有不等式x 2﹣4x ﹣m <0成立”是真命题.(1)求实数m 的取值集合A ;(2)设不等式x 2﹣3ax +2a 2≥0(a ≠0)的解集为B ,若x ∈A 是x ∈B 的充分条件,求实数a 的取值范围. 解:(1)由∀x ∈[﹣1,3],都有不等式x 2﹣4x ﹣m <0成立,得x 2﹣4x ﹣m <0在x ∈[﹣1,3]时恒成立,所以m >(x 2﹣4x )max ,因为二次函数y =x 2﹣4x 在[﹣1,2]上单调递减,在[2,3]上单调递增,且f (﹣1)=5,f (3)=﹣3,当x ∈[﹣1,3]时,y max =5,可得m >5,所以A ={m |m >5}.(2)由x 2﹣3ax +2a 2≥0可得(x ﹣a )(x ﹣2a )≥0.①当a <0时,可得B ={x |x ≤2a 或x ≥a },因为x ∈A 是x ∈B 的充分条件,则A ⊆B ,则a ≤5,此时,a <0;②当a >0时,可得B ={x |x ≤a 或x ≥2a },因为x ∈A 是x ∈B 的充分条件,则A ⊆B ,则2a ≤5,解得a ≤52,此时0<a ≤52.综上所述,实数a 的取值范围是{a|a <0或0<a ≤52}.22.(12分)已知函数f (x )是定义域在R 上的奇函数,当x ≥0时,f (x )=﹣x 2+ax .(1)当a =1时,求函数f (x )的解析式;(2)若函数f (x )为R 上的单调函数.且对任意的m ∈[1,+∞),f(2mt −4m 2)+f(t m −1m 2)>0恒成立,求实数t 的范围.解:(1)当a =1时,当x ≥0时,f (x )=﹣x 2+x ,设x <0,则﹣x >0,所以f (x )=﹣f (﹣x )=﹣(﹣x 2﹣x )=x 2+x ,所以f (x )={−x 2+x ,(x ≥0)x 2+x ,(x <0). (2)因为函数f (x )为奇函数,所以函数f (x )在关于原点对称的区间上有相同的单调性,①当函数f (x )单调递减时,f (x )=﹣x 2+ax 在[0,+∞)上单调递减,又函数f (x )的对称轴为x =a 2,所以a 2≤0,即a ≤0,因为函数f(x)为奇函数,所以f(2mt﹣4m2)+f(tm −1m2)>0,所以f(2mt﹣4m2)>﹣f(tm−1m2)=f(−tm+1m2),又当a≤0时,函数f(x)单调递减,所以2mt﹣4m2<−tm+1m2,所以(2m+1m)t<4m2+1m2=(2m+1m)2﹣4,又m≥1,所以2m+1m>0,所以t<(2m+1m)−4(2m+1m),令g(x)=2x+1x,x≥1,任取x1,x2∈[1,+∞),且x1<x2,所以g(x1)﹣g(x2)=2x1+1x1−2x2−1x2=2(x1﹣x2)+x2−x1x1x2=(x1﹣x2)(2−1x1x2),因为x1<x2,x1,x2∈[1,+∞),所以x1﹣x2<0,2−1x1x2>0,所以(x1﹣x2)(2−1x1x2)<0,即g(x1)<g(x2),所以g(x)在[1,+∞)上单调递增,所以g(x)≥g(1)=3,又令2m+1m=n,则t<(2m+1m)−4(2m+1m),转化为t<n−4n,其中n≥3,所以只需t<(n−4n)min,又注意到函数y=x与函数y=−4x在[3,+∞)上单调递增,则函数y=x−4x在[3,+∞)上单调递增,所以n −4n ≥3−43=53,所以t <53,所以t 的取值范围为(﹣∞,53), ②当函数f (x )单调递增时,f (x )=﹣x 2+ax 在[0,+∞)上单调递增, 又函数f (x )的对称轴为x =a 2, 所以a 2>0,即a >0, 因为函数f (x )为奇函数,所以f (2mt ﹣4m 2)+f (t m −1m 2)>0, 所以f (2mt ﹣4m 2)>﹣f (t m −1m 2)=f (−t m +1m 2), 又当a >0时,函数f (x )单调递增, 所以2mt ﹣4m 2>−t m +1m 2, 所以(2m +1m )t >4m 2+1m 2=(2m +1m )2﹣4, 又m ≥1,所以2m +1m>0, 所以t >(2m +1m )−4(2m+1m ), 令g (x )=2x +1x ,x ≥1,任取x 1,x 2∈[1,+∞),且x 1<x 2,所以g (x 1)﹣g (x 2)=2x 1+1x 1−2x 2−1x 2=2(x 1﹣x 2)+x 2−x1x 1x 2 =(x 1﹣x 2)(2−1x 1x 2), 因为x 1<x 2,x 1,x 2∈[1,+∞), 所以x 1﹣x 2<0,2−1x 1x 2>0, 所以(x 1﹣x 2)(2−1x 1x 2)<0, 即g (x 1)<g (x 2),所以g (x )在[1,+∞)上单调递增,所以g (x )≥g (1)=3, 又令2m +1m =n ,则t >(2m +1m )−4(2m+1m ),转化为t >n −4n,其中n ≥3, 所以只需t >(n −4n )max ,但是n −4n 无最大值,无解,综上所述,t 的取值范围为(﹣∞,53).。

A.“寒喧”的“喧”应写作“暄”;“抡起”的“抡”应读作lūn;B.“佣金”的“佣”应读作yòng;D.“报歉”的“报”应写作“抱”。
故选C。
2. 下列各项中的加点成语使用有误的一项是()A. 也许是由于刚才骑马狂奔出了阵汗,现在骤然一热,我身不由己地打了一个寒噤。
B. 李广志让他休息一下,他却拿出自己画的图来,一边指点,一边娓娓而谈地告诉李广志。
C. 老人一看见它游过来,就知道这是一条毫无畏惧、肆意妄为的鲨鱼。
D. 我过的同样是苦恼自知的生活,而且也跟从前一样,依旧孑然一身,一切都靠自己。
【答案】B【解析】【详解】本题考查学生正确使用成语的能力。
A.正确。
身不由己:身体不能由自己做主。
指行为不能由自己支配。
本句中指因为身体突然的冷热变化导致不由自主地打寒噤,使用该成语是恰当的。
B.错误。
娓娓而谈:形容谈论不倦或说话动听。
缓慢而详细的讲述。
这里强调的是说话的流畅和热情,而不是缓慢详细(动听)。
因此,用“滔滔不绝”更贴切。
滔滔不绝:像水流一样连续不断,没完没了。
C.正确。
肆意妄为:指不顾一切由着自己的性子胡作非为。
这句话中,用来形容鲨鱼那种毫无顾忌、任意胡来的状态,成语使用恰当。
