【题目描述】

● 一个 B 类网络的子网掩码为 255.255.224.0,则这个网络被划分成了 (66) 个子网。

(66)

A.  2       

B.  4     

C.  6     

D.  8

 


正确答案:D

答案分析:

【我的疑问】(如下,请求专家帮助解答)

被划分了8个子网。 B类地址的默认掩码为255.255.0.0,现在变成了255.255.224.0说明原有的主机位被借走做了网络为,224是二进制数11100000的十进制表示方法,说明有3位主机位被借走,借走3位就会有2的3次方个子网。 共划分八个,但是因为第一个子网的网络位和主类网络的网络位相同,最后一个子网的广播位和主类网络的广播位相同,所以要剪掉两个,即六个。但现在的网络中这两个子网通过设置也是可用的。所以,共8个子网
希望对您有帮助,祝您顺利通过考试
子网掩码的2进制形式为11111111.11111111.11100000.00000000
既子网掩码为三位,2^3=8,(000,001,010,011,100,101,110,111)
则该网络被划分为了8个子网。

考题 单选题Passage1Since 1989, Dave Thomas, who died at age 69, was one of the most recognizable faces on TV. He appeared in more than 800 commercials for the hamburger chain named for his daughter.As long as it works, he said in 1991,I' ll continue to do those commercials.Even though he was successful, Thomas remained troubled by his childhood.He still won't let anyone see his feet, which are out of shape because he never had proper fitting shoes, Wendy said in 1993. Born to a single mother, he was adopted as a baby by Rex and Auleva Thomas of Kalamazoo in Michigan. After Auleva died when he was 5, Thomas spent years on the road as Rex traveled around seeking construction work.He fed me, Thomas said, and if I got out of line, he'd beat me.Moving out on his own at 15, Thomas worked, first as a waiter, in many restaurants. But he had something much better in mind.I thought, if I owned a restaurant, he said, I could eat for free. A 1956 meeting with Harland Sanders led Thomas to a career as the manager of a Kentucky Fried Chicken restaurant that made him a millionaire in 1968.In 1969, after breaking with Sanders, Thomas started the first Wendy's Old Fashioned Hamburgers, in Columbus, Ohio, which set itself apart by serving made-to-order burgers. With 6,000 restaurants worldwide, the chain now makes $6 billion a year in sales.Although troubled by his own experience with adoption, Thomas, married since 1954 to Lorraine,66, and with four grown kids besides Wendy, felt it could offer a future for other children. He started the Dave Thomas Foundation for Adoption in 1992.In 1993, Thomas, who had left school at 15, graduated from Coconut Greek High School in Florida. He even took Lorraine to the graduation dance party. The kids voted him most likely to succeed.The Dave you saw on TV was the real Dave, says friend Pat Williams.

考题 问答题《中国青年报》刊登一篇《我是作者,却答不准文章的“作者原意”》的短评,该文作者提到,自己一篇报道被选用为阅读理解的材料,这道12分的题目,他自己最多只能拿到6分。这让作者感到有些尴尬。知名作家周国平,出了一本书《试卷中的周国平:对标准答案说不》。周国平的文章流传广泛,被作为语文阅读理解题,但作者本人做有关题目,在“标准答案”面前,却被判“错”。对此你怎么看?正确答案:周国平的文章流传广泛,是出阅读理解题的好素材。但他似乎并不觉得高兴,原因是,这些以他的文章为材料的阅读理解题,往往让他本人摸不着头脑。比如有一回,他自己做了一道题,结果按照标准答案只能得69分,比有的学生还低。其实这种现象并不罕见。就像网络上一直流传的一个鲁迅的梗。鲁迅:“晚安”!。语文老师:“晚安”中“晚”字点明了时间,令人联想到天色已暗,象征着当时社会的黑暗。而在这黑色的天空下人们却感到“安”,侧面反映出人民的麻木,而句末的感叹号体现出了鲁迅对人民麻木的“哀其不幸怒其不争”。鲁迅:……。被网友戏称“我终于知道我当年语文为什么不好了”这虽然是一个笑话,但是在笑过之后,留给我们的却是对于目前的语文教育的深深思考。一千个人眼里有一千个哈姆雷特”,说的是对待同样的事物,每个人的理解或有不同。文本具有开放性,往往连作者都没有意识到其中的一些奥秘。这其实不奇怪。语文阅读理解之所以要有标准答案,自然是为了方便打分,避免发生歧义。但是,我们也应该看到阅读理解已经偏离了“阅读”和“理解”的本义。按理说,学生看完一则材料,应当从自己的角度分析文本,只要言之成理,就该得分。依赖于标准答案的阅读理解,却人为限制了学生的理解能力与想象力。这对培养学生的阅读与欣赏能力,无疑是一种极大的破坏。归根结底,这又是应试教育体制导致的弊端。在应试化的思维下,任何考试都以成绩为主,以分数决定高下。这在扼杀学生想象力的同时,也会钳制老师的积极性。既然到最后是分数说了算,老师如果把更多精力放在培养学生真正的阅读理解能力上,就会与应试化教育的模式相悖。所以说,最应该反思的就是教育主管部门,我们能够理解改革是需要魄力的,教育改革牵一发动全身,慎重不草率没有错,但不等于可以止步不前。在全面深化改革的背景下,存在问题的应试教育不能一直拖着不改。本该是生动活泼的语文教育,难道就没有任何改革的空间?死抱标准答案的阅读理解题,在题目设计上就应该开放一些,更加迎合这一题型的本义。身处教学一线的语文老师们,要敢于走得更远一些,放手让学生发挥个人思考与判断,只有真的从自身去阅读去理解,才能回归到我们阅读理解的本质上来。解析:暂无解析

考题 单选题—Has Wendy handed in her application form?—Not sure. She told me that she wanted to check again and ______it in soon.A will handB would handC has handedD had handed正确答案:A解析:句意:——温迪上交申请表了吗?——我不确定。她说她想再检查一下,会及时上交的。本题考查动词时态。当主句是过去时态时,宾语从句通常用过去的某种时态,根据题意可知此题应用过去将来时态。故此题答案为B项。
