媒介素养的三个环节是什么

D

本小题考查的是货币。没有难度，只是对基础知识的再现。货币具有价值尺度、流通手段两种基本职能，其根本原因在于货币是一般等价物，可以同一切商品相交换，D符合题意，A、B不是根本原因，能表现其他一切商品的价值是价值尺度，C的说法不符合题意。

In twenty-first Century the mass media as a result of all sorts of media increasingly fierce competition, will inevitably lead to the needs of the audience segmentation and propagators of specialization. In the change and development trend," science and education, health, law, economy is almost everything is contained therein." and be arranged educational programs, the professional characteristic is more obviously. Life services programs as educational programs in a class, the host program form, as the entire program is a host to lead, therefore require the host to have more extensive and professional quality. For the show, the audience tend to favor the authoritative, high credibility of the host, hope they about the knowledge have a greater degree of information share and a more thorough understanding of. At the same time require the host to have rich experience of life, rich life experiences can give host observe things sharp eyes, there will always be some unique and profound insights. Life service show host for the dissemination of the contents of the different focus, the quality of form also has a more strict and specific requirements.

解题思路：根据光的偏折程度比较出两束光的折射率，根据波长的长短，判断谁的衍射现象更明显．根据v=cn比较出在介质中传播速度的大小，根据sinC=1n比较出临界角的大小．

A、①光的偏折程度较大，则其折射率较大，因为蓝光的折射率大于红光的折射率，所以①光是蓝光，②是红光．故A正确；
B、②光的折射率较小，频度较小，波长较长，波动性较强，所以②光衍射更明显．故B错误；
C、根据v=[c/n]知，蓝光的折射率大，在介质中的速度小，则光束①比光束②传播速度更慢．故C错误；
D、根据sinC=[1/n]知，蓝光的折射率大，临界角小，增大入射角，蓝光先发生全发射．即①先发生全反射．故D错误．
故选：A．

点评：
本题考点： 光的折射定律．

考点点评： 解决本题的突破口是比较出两束光的折射率大小，再比较出频率、波长、在介质中的速度、临界角的大小．

解题思路：（1）声音是由物体的振动产生的，声音的传播需要介质，真空不能传声；（2）声音在不同介质中的传播速度不同，固体传声最快，液体次之，气体最慢．

声音是由发声体的振动产生的，声音在不同介质中的传播速度不同，一般情况下，声音在空气中的传播速度小于其在液体中的传播速度，在液体中的速度小于在固体中的传播速度，在真空中不能传播．
故答案为：振动；不同；小于；小于；不能．

点评：
本题考点： 声音的产生；声音的传播条件．

考点点评： 本题考查了声音的产生和传播，属于声学基础知识的考查，比较简单．

解题思路：熟悉记忆血红蛋白提取和鉴定实验的原理，操作步骤．注意事项．

（1）生理盐水保持红细胞渗透压的稳定而不破碎在未洗净血浆中杂质蛋白前，红细胞如果破裂了，就可能是血红蛋白和杂质蛋白混在一起，加大分离难度． 故答案为：防止红细胞吸水破裂（2）加蒸馏水是让细胞吸水膨胀破裂．细胞膜主要成分是磷脂，易溶于甲苯等有机溶剂，加入甲苯能加快红细胞破碎并释放出红细胞． 故答案为：蒸馏水和甲苯
（3）凝胶色谱法，根据相对分子量大小分离物质，分子量大的先分离出来，分子量小的之后分离出来． 故答案为：相对分子质量大小
①相对分子质量大的物质，无法进入凝胶珠中的通道孔，只能留在凝胶珠之间的空隙中． 故答案为：aa相对分子质量大，无法进入凝胶内部的通道，只能在凝胶外部移动，路程较短，移速较快②装填凝胶色谱柱时，色谱柱内不能有气泡存在，因为气泡会扰乱洗脱液中蛋白质的洗脱次序，降低分离效果． 故答案为气泡会扰乱洗脱液中蛋白质的洗脱次序，降低分离效果．（4）血红蛋白提取和分离的程序为：样品处理（红细胞洗涤、血红蛋白的释放）、粗分离（分离血红蛋白溶液、透析）、纯化和纯度鉴定． 故答案为：样品处理、粗分离、纯化

点评：
本题考点： 酶活力测定的一般原理和方法．

本题考查旅游业。旅游业是旅游活动三要素之一，旅游业是旅游活动的媒介，主要包括旅游交通、食宿、通信、购物、娱乐场所等方面的服务。旅游业是第三产业中的支柱产业。旅游活动中会出现各种环境问题，因此旅游业并不是“无烟工业”。

①没有细胞与细胞间进行物质交换的说法,只有细胞与外界环境之间进行物质交换.因为细胞是浸在组织液中的,隔着组织液呢.嗯嗯,细胞应该是与细胞外液中进行物质交换.
②细胞外液又叫内环境.内环境即细胞外液是细胞与外界环境进行物质交换的媒介

我们以前也有这种形式的.大多数同学都是以做ppt为主,内容比较多,包括旅游,书籍,人生,哲学,健康,或者文学.快要该你的话,可以切合时间,比如即将到来的圣诞节.
我们以前也有人讲《狼图腾》,《悲伤逆流成河》,都有很好的反响.不需过于注重形式的新颖,只要内容有新意,或有深度,不失为很好的选择.

解题思路：地震波分为横波和纵波，横波速度慢只能在固体中传播，纵波速度快可以在固、液和气体中传播．根据这一特点，如果海底储有石油，横波无法通过液体会消失．

横波无法通过液体，所以如果海底储有石油的话，那横波会消失，根据这一原理可直接选出答案．
故选：A

点评：
本题考点： 地球的圈层结构．

考点点评： 本题考查了横波和纵波的特点，学生只要对横波的特点有所了解解题就不难．

American global culture is controlled by the mass media control to achieve,and mass media itself has also become a kind of hegemonic form,this is the so-called "media hegemony".
Hollywood movies,TV and radio broadcast all over the world,formed the media hegemony.The brunt of the Star Wars,is forrest gump,Jurassic park ","saving private Ryan,mission,etc,especially those who invest in Hollywood blockbuster film giant entertainment at the most of the global box-office.
American culture industry to create a special kind of "American image".Most of the people,and is often through mass media publicity.However,the mass media is American,led by the modern science and technology can they make their way to the image and make America has become a symbol of freedom,equality,democracy.
Indeed,in the Hollywood film,often preached is an American humanitarian concern,such as the field row (war) performance distortion of humanity,war gladiator (history) performance history,the concept of justice crystallized (science subject to external pressure) performance of mankind,"American beauty" (romantic theme) performance of love,the middle class.
Relying on powerful strength,Hollywood has made another legend,they first box of other countries eye on lies in history,history,easier to incur the possibility of fierce reaction is lesser also.Its purpose is still the implementation of "cultural aggression".Hollywood can use American values and cultural standard to conjecture and transformation of the foreign country,a history,ethnic,traditional historical themes processing of American,into a Hollywood movie text and postmodernism.Proficient in their business logic to operate,and around the world.

解题思路：（1）把图表数据求出平均数，然后根据绝对值的性质进行计算即可得解；
（2）把x、y的值代入进行计算，然后进行判定即可．

（1）A₁=[1/6]（1.78+1.86+1.96+2.00+2.00+1.86）=[1/6]×11.46=1.91，
A₂=-[1/6]（1.14+1.20+1.18+1.26+1.28+1.29）=[1/6]×7.35=1.225；
B₁=[1/6]（1.72+1.74+1.70+1.82+1.82+1.82）=[1/6]×10.62=1.77，
B₂=[1/6]（1.24+1.36+1.41+1.38+1.48+1.50）=[1/6]×8.37=1.395，
所以，|A₁-B₁|+|A₂-B₂|=|1.91-1.77|+|1.225-1.395|=0.14+0.17=0.31；
（2）x=1.80，y=1.24时，|x-A₁|+|y-A₂|=|1.80-1.91|+|1.24-1.225|=0.11+0.015=0.125，
|x-B₁|+|y-B₂|=|1.80-1.77|+|1.24-1.395|=0.03+0.155=0.185，
∵0.125＜0.185，
∴该蠓虫是B种蠓虫．

①从上表可以得出
A1= 1.91
A2= 1.23
B1= 1.77
B2= 1.40
∴|A1-B1|+|A2-B2|=0.14+0.17=0.31．
②将x=1.80,y=1.24代入|x-A1|+|y-A2|
|x-A1|+|y-A2|=0.11+0.01=0.12
将x=1.80,y=1.24代入|x-B1|+|x-B2|
|x-B1|+|x-B2|=0.03+0.16=0.19
∵0.12＜0.19

其中我不太确定招标和竞标的英语表达,因为在很多情况下都是用bidding.所以我就用inviting bidding来表示招标,competing bidding表示竞标.如果你知道确切表达的话,可以自己改一下.其他的专业词汇基本查实.

流通手段强调的是货币在商品交换中的作用，而商品流通强调的是商品如何进行交换，强调交换的形式。

解题思路：根据折射定律n=[sini/sinr]求折射率．不同颜色的激光在透明介质层中的折射率不同，根据v=[c/n]分析光在介质中传播速度．产生全反射的条件是光从光密介质进入光疏介质，入射角大于临界角．光的频率与介质无关．

A、由图知，激光束斜射到盘面上，入射角i=90°-α，折射角r=90°-β，则透明介质的折射率n=[sini/sinr]=
sin(90°−α)
sin(90°−β)=[cosα/cosβ]，故A错误．
B、透明介质对不同颜色的激光折射率n不同，根据v=[c/n]分析可知，光在介质中传播速度不同，故B正确．
C、因为光从空气射入介质时，折射角小于入射角，不可能发生全反射，故C错误．
D、激光束进入透明介质层后频率不变，因为光的频率由光源决定，与介质无关，故D错误．
故选：B．

点评：
本题考点： 光的折射定律．

考点点评： 本题考查折射定律、光速与折射率的关系式、全反射条件等等基础知识，要正确理解折射定律n=[sini/sinr]中i和r的含义，这两个角都是指与法线的夹角，不是与界面的夹角．
