在计算机中,你既然已经知道彼此间的换算那就好办多了.
1KB=1024B,1MB=1024KB,1GB=1024MB
这样：
8GB=8X1024X1024X1024=8589934592B

解题思路：由容斥原理可知：参加了英语课外小组的有32位同学加上参加了信息技术课外小组的有20位同学，再减去40人就是两个小组都参加的同学．

32+20-40
=52-40
=12（位）
答：两个小组都参加的同学12位．

点评：
本题考点： 容斥原理．

考点点评： 本题为基本的容斥原理题目，其公式为：A类B类元素个数总和=属于A类元素个数+属于B类元素个数-既是A类又是B类的元素个数．

解题思路：通电螺线管的磁场分布相当于条形磁铁，根据磁感线的疏密程度来确定磁感应强度的大小．

通电螺线管的磁场分布相当于条形磁铁，内部磁感线的分布均匀，是匀强磁场，管口磁感线较管内磁感线稀疏，磁感应强度较小，故B正确，ACD错误．
故选：B

点评：
本题考点： 法拉第电磁感应定律．

考点点评： 考查通电螺线管周围和内部磁场的分布，及磁感线的疏密程度来确定磁感应强度的大小，本题较简单但会出错．

The information age, more and more of the information technology is applied to every aspect of life, radically affect the way people live. Tourism is also happening the great change, the traditional travel way is being intelligent tourism way replaced. So, wisdom tourism have to do is to provide the most accurate human intelligence tourism services, let tourists to travel to perceive the relevant information. The current situation of the development of the tourism wisdom to popularity of intelligent tourism manner, and promote the modernization of tourism consumption, carry forward to provide services for tourists of thought, make a kind of tend to perfect the traveling service.
This paper expounds the definition of tourism and wisdom background, this paper analyzes the current situation of the development of the tourism of ningbo wisdom, show that the way to travel the necessity of wisdom. According to the survey of ningbo, including made a survey of the basic situation of the crowd, the understanding of the tourism of wisdom and the analysis of the present situation, the use of Excel in data analyses and summarizes the survey of basic condition, the author puts forward the wisdom tourism, and the problems in view of these questions proposed some Suggestions.

第一步 s=1 a 为3 是Sㄑ10 所以 1*3 =3 回头再来 第二次 S=3 开始 a为5 S仍ㄑ10 所以 3*5=15 注意 这时候 a 为2 但 S 已经 大于10 所以不用 进行 这步 直接输出S 所以 为c 15

你可以代入一些数字进去算,比如令a=1,b=2
然后可以发现,这个程序是使a,b交换数字,便可以得出是C答案

（1）[200×25%×80%+200×40%×85%+200×(1-25%-40%)×90%]/200
=[200×25%×80%+200×40%×85%+200×35%×90%]/200
=(40+68+63)/200
=85.5%
（2）设从甲公司购买x台,则需要从乙公司购买200-150-x=50-x台
则可得
[80%x+85%(50-x)+150×90%]/200=88.5%
则,177.5-5%x=200×88.5%
解得,x=10
则50-x=40

D 其它说的有点道理

答案C
解答本题应懂得发展的实质和判断新旧事物的标准.利用先进的信息技术搞“科学算命”,冠以“新潮”的名字,称之为“时代的发展”,这是没有弄清发展的实质是什么,混淆了判断新旧事物的标准,仅从事物的名称、旗号等表面形式上判断新旧事物,故A、B、D三项是错误的.

现代战争中,信息技术的重要影响：能称得上是第一场高科技局部战争,是在1991年的海湾战争,在海湾战争中,美军及其友军面对的是,陆军号称是“世界第四”的伊拉克,要与伊拉克面对面的人海作战,始终是不太现实的,始终会有很大的伤亡,所以,“信息化条件下的现代战争理论”开始出台,就是利用信息化高科技,迅速打赢局部战争,将己方的伤亡降到最低.这就是信息化战争的开端,在这战场战争中,美军及其盟友的整 个作战过程分是为四个阶段,即1．战略空袭； 2．夺取制空权；3．空袭地面部队；4．地面进攻作战.可见,信息化,贯穿着整场战争,还没开战,美军的特种兵就进入了伊拉克首都巴格达,为美军及其盟友收集情报.美军开始将大量的高科技武器投入这场战争,侦查卫星、机载侦查、地面雷达等等,做到了全天候、全覆盖,为作战指挥中心回收情报,使作战行动向全天候、高速度、全时域发展.做到了,海陆空天,全面协调,协同作战,多维对单维,立体对单面,这场战争的结果是伊军伤亡约10万人(其中2万人死亡),17.5万人被俘,损失了绝大多数的坦克、装甲车和飞机.而美军只有148人阵亡(非战斗死亡138人),458人受伤(非战斗受伤2978人).其他国家阵亡192人,受伤318人.真正做到了,迅速取胜,将伤亡做到到很低.可见,信息技术对现代战争的影响,是非常大的.
发展趋势：海湾战争后,各国开始大量的装备自己部队,向信息化发展,特别是我国,机载警报和控制系统以及卫星通信系统等,有了很大的发展.现代战争的趋势,向着信息化迈进.

High school Chinese elective courses, the method of the study means network
The network information times calls for modern teaching way, with the popularity of information technology and network teaching practice, the launch of the more and more schools and teachers' active committed to network teaching research. Especially since the implementation of the new curriculum high school Chinese elective courses, the use of network means has been cause for concern. This paper makes a study of the high school Chinese elective courses using network means, why and how the present situation of using network means, how to effectively use the network means more strong teaching form operational mode.
This research mainly adopts literature analysis, interviews, questionnaire investigation, observation and experience method, and tried to in the research method of innovation. The literature analysis method presented in this paper to the theoretical basis of the interview, questionnaire description and analysis of the new curriculum reform area high school teachers of Chinese language by means of the network of elective courses and teaching students to understand the present situation of the network teaching. Observation mainly through teachers of Chinese language teaching examples of observation, using network to the understanding of the means of elective course teaching the concrete methods and existing problems. Experience method is mainly based on teaching practice in the process of using network teaching means and proves that high school Chinese elective course teaching how to use network means.
This research gets the following conclusions: high school Chinese elective course Settings required elective course teaching more flexible and expanding, let the students according to their interests choose the course; But school running conditions, teachers and is very limited, and use the network method for the elective course teaching has become the choice of the era, and advantages are also more prominent. Basic education is concerned, for modern teaching equipped with improve a lot, but the hardware are equipped with jagged, software resources construction should strengthen perfect dynamics, the construction of hidden thing cannot be ignored, technical ability training teachers to pay close attention to. According to the actual situation of the teaching comprehensive analysis, project page type reading teaching mode, BBS type writing teaching mode, remote auxiliary type teaching mode is the operational compare strong teaching mode.

针对二年级小朋友的年龄特点,我对二年级第一个学期的教学做出以下的安 排：以 “画图”软件为学习平台.这款软件是一个绘图软件,可以帮助小朋友 们用很简单的步骤画出美丽的图片,在教小朋友们绘制美丽的图画的同时,他们 会更加的熟悉鼠标的使用.还可以培养他们丰富的想象力和创造力.二年级的小朋友活泼好动,他们都非常听话懂事,但是很容易在上课走神或 者忘记老师讲过的话.针对他们这些特点,我在教学上要尽量安排一些吸引小朋 友注意的小环节,在练习课上要常常评比画得最好的小画家,在课堂上展示一些 小朋友画得非常漂亮的图片.在教学中还应该注意到培养学生良好的操作习惯、 安全意识、卫生习惯.让学生们学会用正确的方法开机和关机.教会小朋友不要 接解电脑后面的插座.不能用湿了的手去接触电脑的铁制部分.要讲卫生,讲礼 貌.不能在机房乱扔.不要和其它小朋友争吵等等.
教材分析
二年级上学期教材内容为：画图.这学期的主要任务是教会学生使用软件 “画 图” .通过这个软件的学习,要求学生能够使用电脑绘制出一些简单的图案.其 中也讲解计算机的启动与退出.其次,在每节课中要注意培养学生良好的操作习 惯、安全意识、卫生和行为习惯.小小画家这个教材针对了二年级小学生的特点.教材基本以图画为主.每个 内容课文都给了一个简单的图画做了一个非常详细的步骤图.教师可以在小学生 面前给他们示范一次这些步骤.这个过程主要是让小学生们熟悉软件的工具使用.在步骤图后面的一页里面,有很多使用这些工具可以做出来的图片样本.可以让 学生们自己把这些图片在电脑上面做出来.同时也鼓励小学生有自已的创意和想 法.做出自已创造和设计的图片.
教学总目标
1、教会学生使用软件“画图” .通过这个软件的学习,要求学生能够使用电
脑绘制出一些简单的图案.2、让学生们认识计算机,喜欢计算机.3、在教学中还应该注意到培养学生良好的操作习惯、安全意识、卫生和行 为习惯.
教学措施
学期教学具体措施.根据本学期教学目标及学生学习的年龄特点特做以下计 划：1 、采用任务驱动教学,和各种直观教学方法,注重保持学生的学习兴趣.任务驱动教学是小学信息技术教学中常用的方法,它符合探究式教学模式,适用 于培养学生的创新能力和独立分析问题、解决问题的能力.低段学生的具体形象 思维毕竟占主导地位
