《典范英语》(8_03)教学参考The Ultimate Trainers教学参考的目的在于为实验课提供一个基本的思路和框架,帮助实验教师更好地把握课题理念。

课题组鼓励实验教师结合学生的实际情况适当做出调整,将实验课上出特色。

一、教学目标1.语言目标:学生能够听懂并理解故事的内容;能够有感情地朗读;能够复述故事的主要情节;能够完成与故事相关的写作任务。

2.非语言目标:引导学生用平常心看待输赢和得失;启发学生思考比赛的真正意义(如重在参与,全力以赴),勇于挑战自我,展现体育精神(Swifter, Higher, Stronger)。

说明:语言目标由教师负责检查,确保学生完成任务,达到要求。

非语言目标具有开放性,需要教师围绕有意义的话题与学生进行真诚交流,激发学生的学习兴趣和参与热情,让学生在有思想、有内容的开放性语言实践活动中习得语言,树立正确的价值观。

Does it matter what kind of trainers you wear?If you found a pair of magic trainers, what would you do?教师简要总结后,引导学生进入故事情景:In this story, who would take part in a running race? What did he find before the race? Did he win at last? Why? Let's find the answers from the story.2. 情节分析及复述(Plot Analysis and Retelling ):启发学生思考;关注内容与语言表达的准确性,锻炼学生连贯表达思想的能力教师在黑板上板书每章的标题,然后请学生将各章纳入“introduction — build-up — climax — resolution ”的结构中去,可参考以下: Chapter 1 The perfect trainers (P3) IntroductionChapter 2 Kevin Beadle (P9)Build-upChapter 3 Jake tries them out (P12)Chapter 4 Anna works it out (P17)Chapter 5 ‘It won’t prove anything’ (P24)Chapter 6 Jake makes up his mind (P27)Climax Chapter 7 Where are the trainers? (P33)Chapter 8 The big race (P37)Chapter 9 The trainers get their own back (P46)Resolution Chapter 10 Back to whenever (P52) 然后教师针对每个部分进行提问,请学生回答:Introduction:Where did Jake find the trainers?What was Anna’s suggestion?What was Jake’s decision?Build-up:What did Beadle do to Jake when he was waiting for Anna?When Jake tried the trainers out, what happened?What was Anna’s explanation for the magic trainers?

Chapter 6一道题
1.What does it mean for a wireless network to be operating in “infrastructure
mode”? If the network is not in infrastructure mode, what mode of operation is it in, and what is the different between that mode of operation and infrastructure mode?
无线网络是在“基础结构模式”操作是什么意思?如果网络不处于基础设施模式,它的操作模式是什么,并且操作模式和基础设施模之间的不同?
在操作中的基础设施模式中,每个无线主机经由基站(接入点),连接到更大的网络。

如果未处于基础设施模式中,网络工作在ad-hoc模式。

在ad-hoc模式中,无线主机有要连接没有基础设施。

在没有这种基础设施,主机本身必须提供的服务,例如路由,地址分配,DNS状名称翻译,等等。

2. What are the four type of wireless networks? Which of these types of wireless networks have you used?
2.What are the differences between the following types of wireless channel
impairments: path loss, multipath propagation, interference from other sources?
以下类型无线通道损伤之间的差异:路径损耗,多径传播,干扰从其它来源?
路径损失是由于当它穿过物质时电磁信号的衰减。

多径传播的结果,在接收到的信号的接收机处模糊,发生在电磁波的部分反射离开对象和地面,同时考虑发送器和接收器之间的不同长度的路径。

当其它源也发送在相同的频率范围作为所述无线网络从其他源的干扰发生。

3.As a mobile node gets farther and farther away from a base station, what are
two actions that a base station could take to ensure that the loss probability of a transmitted frame does not increase?
作为移动节点,到基站的距离越来越远,基站可以采取哪两个措施以确保发送的帧的丢失概率不会增加?
4.If a node has a wireless connection to the Internet, does that node have to be
mobile? Explain. Suppose that a user with a laptop walks around her house with her laptop, and always accesses the Internet through the same access point. Is this user mobile from a network standpoint? Explain.
如果一个节点具有到因特网的无线连接,该节点是否必须移动?说明。

假设有一台笔记本电脑用户围绕她家走路时她的笔记本电脑,始终接入互联网,通过同一接入点。

从网络的角度来看这个用户移动?说明。

不。

节点可以保持连接到其整个到互联网(因此,不进行移动)连接同一接入点。

移动节点是
随着时间的推移改变其连接点到网络中的之一。

由于用户是通过同一个接入点始终接入互联网,
她是不是手机。

6. What is the difference between a permanent address and a care-of address? Who assigns a care-of address?
永久地址为移动节点的IP地址,当它是在它的归属网络。

转交地址当它访问外部网络获取。

COA
由外地代理(它可以是在外籍网中的边缘路由器或移动节点本身)分配。

7. What are the purposes of the HLR and VLR in GSM networks? What elements of mobile IP are similar to the HLR and VLR?
GSM网络的HLR和VLR的目的是什么?元素的移动IP与HLR和VLR有什么类似?
在GSM中的归属网络维护称为归属位置寄存器(HLR)数据库,其包含关于每个其订户的永久手机号码和订户简档信息。

HLR中还包含关于这些用户的当前位置的信息。

被访问网络维护称为访问者位置寄存器(VLR)的数据库,其中包含每个移动用户当前正在由VLR所服务的网络部分的条目。

VLR条目这样来来去去,因为移动用户进入和离开网络。

在移动IP的家庭网络的边缘路由器是类似于HLR在GSM和在外地网络的边缘路由器是类似于在GSM中的VLR中。

8. In mobile IP, what effect will mobility have on end-to-end delays of datagram between the source and destination?
在移动IP,将移动性对源和目标之间的数据包的终端到终端的延迟什么样的影响
Because datagrams must be first forward to the home agent, and from there to the mobile, the delays will generally be longer than via direct routing. Note that it is possible, however, that the direct delay from the correspondent to the mobile (i.e., if the datagram is not routed through the home agent) could actually be smaller than the sum of the delay
from the correspondent to the home agent and from there to the mobile. It would depend on the delays on these various path segments. Note that indirect routing also adds a home agent processing (e.g., encapsulation) delay.
因为数据报必须先被向前到归属代理,并从那里向移动时,延迟将通常比通过直接路由更长。

需要注意的是它是可能的,然而,该直接延迟从对应向移动(即,如果数据报是通过归属代理不路由)实际上可能比延迟之和较小的
从对应到归属代理,并从那里向移动。

这将取决于这些不同的路径段的延迟。

需要注意的是间接路由还增加了一个本地代理处理(例如,封装)延迟。
