The Importance of Information in the Supply Chain Information is important because it provides the facts that supply chain managers use to make decisions. Without information, a manger will not know what customers want, how much inventory is in stock and when more products should be produced and shipped. In short, without information, a manager can only make decisions blindly. Managers must understand how information is gathered and analyzed. This is where information technology comes into play. Information technology serves as the eyes and ears of management in a supply chain, capturing and delivering the information necessary to make a good decision. For instance, an IT system at a personal computer manufacturer may help a manager analyze the information and recommend an action. The manager can use the remaining chips first, then look at demand forecast, and determine whether to order more chips. There are four reasons why timely and accurate information has become more important for effective logistics system design and operations. First, customers recognize information about order status, product availability, delivery schedule, and shipment tracking as necessary elements of total customer service. Then, managers realize that information can be used to reduce human resource requirements. What’s more, information increases flexibility with regard to how, when, and where resources may be used to gain strategic advantage. And finally, enhanced information transfer and exchange capability using the Internet is changing relationships between buyers and sellers and refining channel relationships.21.

Pharming is a scamming practice in which malicious code is installed on a personal computer or server, misdirecting users to (71)Web sites without their knowledge or consent. Pharming has been called "phishing without a lure".In phishing, the perpetrator sends out legitimate-(72)e-mails, appearing to come from some of the Web's most popular sites, in an effort to obtain personal and financial information from individual recipients. But in pharming, larger numbers of computer users can be(73)because it is not necessary to target individuals one by one and no conscious action is required on the part of the victim. In one form. of pharming attack, code sent in an e-mail modifies local host files on a personal computer. The host files convert URLs into the number strings that the computer uses to access Web sites. A computer with a compromised host file will go to the fake Web site even if a user types in the correct Internet address or clicks on an affected(74)entry. Some spyware removal programs can correct the corruption, but it frequently recurs unless the user changes browsing( 75 ).A．fewB．fraudulentC．normalD．structured
(C)“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.The program allows users to display alerts on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.Owners must report their laptop missing by logging on to a website, which sends a message to the model: a red and yellow “lost or stolen” banner pops up on its screen when it is started. Under the latest version(版本) of the software, users can also send a spoken message.The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, ‘You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.In the latest version, people can add a spoken message. The default through the computer’s speakers is: “Help, this laptop is reported lost or stolen. If you are not my owner, please report me now.”The Retriever software package, which costs $29.95 (￡21) but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password prompt if they fear that the thief has also got hold of the access details.If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.Other security software allows users to erase data remotely or lock down the computer.72. The expression “to give the thief a piece of their mind” can be understood as “_______”.A. to give the thief an alert mind B. to express the owners’ anger to the thiefC. to remind the thief of his conscience D. to make the thief give up his mind

共用题干第一篇Computer LiteracyThere is no denying that students should learn something about how computers work,just as we expect them at least to understand that the internal-combustion engine（内燃机）has something to do with burning fuel, expanding gases and pistons（活塞）being driven. For people should have some basic idea of how the things that they use do what they do.Further,students might be helped by a course that considers the computer's impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy（读写能力）。It is a trade skill that should not be taught as a liberal art.Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers.But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun,and while our society needs some people who are experts at it,the same is true of auto repair and violin-making.Learning how to use a computer is not that difficult,and it gets easier all the time as programs become more"user-friendly".Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen.What does the phrase"learning to use a computer" mean? It sounds like"learning to drive a car",that is,it sounds as if there is some set of definite skills that,once acquired,enable one to use a computer.In fact,"learning to use a computer" is much more like"learning to play a game",but learning the rules of one game may not help you play a second game,whose rules may not be the same.

问答题Practice 4 Read the following text(s) and write an essay to 1) summarize the main points of the text(s), 2) make clear your own viewpoint, and 3) justify your stand. In your essay, make full use of the information provided in the text(s). If you use more than three consecutive words from the text(s), use quotation marks (“ ”). You should write 160—200 words on the ANSWER SHEET. The information and computer technologies have boosted the efficiency and convenience of people’s work and study. Their application in school education has provided teachers and students with new approaches to knowledge and information. There is a heated discussion about whether computers will replace teachers. The following are the supporters’ and opponents’ opinions. Supporters: With the advanced computer and Internet, children can get the learning material whenever they want. Online teaching is becoming more and more popular that students can get planned lessons online. After each class, there is homework for them to do. Both the learning and practice can be done on computers. From computers students can learn something that they are interested in so that they won’t be restricted to the subjects that they are taught at school. Therefore, students will have the opportunity to achieve an all-around development. Opponents: Students need to communicate with teachers and get instructions from them whenever they have troubles in their study. Computers are only cold devices that will affect children’s ability to have face-to-face communication. Education is not only about imparting the knowledge, but also being a useful person. So students need to learn some useful values to be a good person which sometimes cannot be easily learned from computers. Children who use computer will learn to communicate with machines instead of people. There is a risk that they will be a generation of social illiterates.
