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.

The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, __1__ this is largely because, __2__ animals, we stand upright.

In fact, __5__, we are extremely sensitive to smells, __6__ we do not generally realize it. Our noses are capable of __7__ human smells even when these are __8__ to far below one part in one million.Strangely, some people find that they can smell one type of flower but not another, __9__ others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate __10__ smell receptors in the nose. These receptors are the cells which sense smells and send __11__ to the brain. However, it has been found that even people insensitive to a certain smell __12__ can suddenly become sensitive to it when __13__ to it often enough.The explanation for insensitivity to smell seems to be that brain finds it __14__ to keep all smell receptors working all the time but can __15__ new receptors if necessary.

Passage ThreeEducation is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them; our purpose is to prepare them for life. As soon as we realize this fact, we will understand that it is very important to choose a system of education which will really prepare children for life. It is not enough just to choose the first system of education one finds, or to continue with one's old system of education without examining it to see whether it is in fact suitable or not.In many modern countries, it has for some time been fashionable to think that by free education for all—whether rich or poor, clever or stupid—one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider "low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor. We can live without education, but we will die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability, and secondly, we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.44. Education is______.A. a purposeB. a meansC. fashionableD. the first system

共用题干第三篇On the Trail of the Honey BadgerOn a recent field trip to the Kalahari Desert,a team of researchers learnt a lot more about honey badgers（獾）.The team employed a local wildlife expert,Kitso Khama,t& help them locate and follow the badgers across the desert.Their main aim was to study the badgers'movements and behaviour as discreetly （谨慎地）as possible,without frightening them away or causing them to change their natural behaviour. Theyalso planned to trap a few and study them close up before releasing them.In view of the animal's reputation, this was something that even Khama was reluctant to do. "The problem with honey badgers is that they are naturally curious animals, especially when they see something new,"he says. "That, combined with their unpredictable nature,can be a dangerous mixture. If they sense you have food ,for example , they won't be shy about coming right up to you for something to eat. They're actually quite sociable creatures around humans ,but as soon as ther feel they might be in danger, they can become extremely vicious（凶恶的）.Fortunately this is rare ,but it does happen."The research confirmed many things that were already known.As expected , honey badgers ate any crea- tures they could catch and kill. Even poisonous snakes , feared and avoided by most other animals,were not safe from them. The researchers were surprised , however, by the animal' s fondness for local melons , probably because of their high water content. Previously researchers thought that the animal got all of its liquid require- ments from its prey（猎物）.The team also learnt that , contraryto previous research findings, the badgers oc- casionauy formed loose famiiy groups. They were also able to confirm certain results Irom previous research,including the fact that female badgers never socialised with each other.Following some of the male badgers was a challenge,since they can cover large distances in a short space of time. Some hunting territories cover more than 500 square kilometers. Although they seem happy to share these territories with other males,there are occasional fights over an important food source, and male badgers can be as aggressive towards each other as they are towards other species.As the badgers became accustomed to the presence of people , it gave the team the chance to get up close to them without being the subject of the animals'curiosity-or their sudden aggression. The badgers'eating patterns, which had been disrupted,returned to normal. It also allowed the team to observe more closely some of the other creatures that form working associations with the honey badger, as these seemed to adopt the badgers' relaxed attitude when near humans.Why did the wildlife experts visit the Kalahari Desert?A: To find where honey badgers live.B: To catch some honey badgers for food.C: To observe how honey badgers behave.D: To find out why honey badgers have a bad reputation.

As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.People are finding less and less time for relaxing themselves because___D__.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the time d.they are becoming busier with their work

In a world where it seems we already have too much to do，and too many things to think about，it seems the last thing we need is something new that we have to learn.But use cases do solve a problem with requirements:with（ ）declarative equirements it's hard to describle steps and sequences of events.Use cases，stated simply，allow description of sequences of events that，taken together，lead to a system doing something useful.As simple as this sounds，this is important.When confronted only with a pile of requiements，it's often（ ）to make sense of what the authors of the requirements really wanted the system to do.In the preceding example，use cases reduce the ambiguity of the requirements by specifying exactly when and under what conditions certain behavior occurs;as such，the sequence of the behaviors can be regarded as a requirement.Use cases are particularly well suited to capture approaches.Although this may sound simple，the fact is that（ ）equirement capture approaches，with their emphasis on declarative requirements and"shall"statements，completely fail to capture the（ ）of the system's behavior.Use cases are a simple yet powerful way to express the behavior of the system in way that all stakeholders can easily understand.But，like anything，use cases come with their own problems，and as useful as they are，they can be（请作答此空）.the result is something that is as bad，if not worse，that the original problem.Therein it's important to utilize use cases effectively without creating a greater problem than the one you started with.A.misappliedB.appliedC.usedD.powerful
