【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 共用题干 A Minor Microsurgery Last year,Sean Martinovich,from Whitianga,had life-saving surgery when a golf-sized tumor was removed from his brain stem.But the operation left half his face paralysed.He talked with a slur,sometimes dribbled(流 口水)out of the side of his mouth and could not close his eye properly.Although he could run around with the other boys in the playground,when they laughed he could not laugh with them.Without a smile,he could suffer psychologically and emotionally. Last week,6-year-old Sean had seven hours of microsurgery that should give him back his smile.Doctor Bartlett removed a nerve from the back of one of Sean's legs and transplanted it into his face.On the normal side of his face the nerve divides into lots of little branches."We'll cut those nerve branches and then we'll take a nerve graft from one leg and tunnel it across his face from one side to the other and join that on to the nerve that' s been cut on the good side of his face."Doctor Bartlett said before the operation."If this was not fixed he conld face physical and emotional problems as he got older,"Doctor Bartlett said."Socially people can become quite withdrawn because of the face paralysis.It's easy for people,especially children,to become rather emotionless because they prefer the flatness of no movement on either side to the weirdness of an asymmetry of smiling on one side and having this twisted face." Sean is not smiling yet.Over the next six months the nerves will grow across the face to the damaged side and after that movement will hopefully come back.Sean's parents,Steve and Wendy Martinovich,said they had been through a year of hell.But their son was a determined boy who just got on with it,said Mrs Martinovich.They are amazed at the technology that they hope will restore the cheeky smile they love so much.For Doctor Bartlett the microsurgery is almost routine.For Sean's parents,it is a miracle.According to the passage,which of the following is true?A:Sean Martinovich couldn't run around with the other boys in the playground now.B:Hopefully,Sean Martinovich can smile over the next three months.C:Sean's parents,Steve and Wendy Martinovich don't believe the technology will restore the cheeky smile.D:For Doctor Bartlett the microsurgery is just a minor and easy case.答案:D解析:第一段第一句表明,Sean是在去年做的手术;第二段第一句表明,上周Sean的年龄为6岁。所以去年手术时、Sean的年龄应为5岁。第一段第三句表明,Sean谈吐不清,有时会流口水,还不能正常地闭眼睛;第一段最后一句说明他不能微笑。综合这些可推知," paralysed"、的意思为“瘫痪的”,也就是失去了感觉和对肌肉的控制。根据第二段第四句引用的Bartlett医生的话语可知,移植到Sean脸上的神经来自于他的腿上。由第二段最后两句引用Bartlett医生的话语可知,由于面部瘫痪,人们会变得很内向。特别是孩子,宁愿与面无表情的人接触,也会远离只有半边脸微笑的不对称表情。由此推测,Sean可能为了避免让别人发现他那不对称的微笑而采取躲避的方法,这会引起一系列生理问题和心理问题。第三段倒数第二句说明,对于Bartlett医生来说,微创手术是“routine"(日常工作),可见微创手术对Bartlett医生来说是一件很容易的事。

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. He wasn't a great actor or a great speaker. He was just Joe Everybody.What do we know about his childhood?A He lived a poor life.B He had caring parents.C He stayed in one place.D He didn't go to school.正确答案:C解析:
