Murphys Law suggests, If anything can go wrong, it will. Murphy has motivated numerous pearls of wisdom about projects; machines, people, and why things go wrong. A project is a [temporary] sequence of unique, complex, and connected（ ）having one goal or purpose and that must be completed by a specific time, within budget, and according to （ ）.Project management is the（ ）of scoping, planning, staffing, organizing, directing, and controlling the development of an acceptable information system at a minimum cost within a specified time frame. Project management is a cross life cycle activity because it overlaps all phases of any systems development methodology. For any systems development project, effective project management is necessary to ensure that the project meets the deadline, is developed within a (an) （ ）budget, and fulfills customer expectations and specifications. Corporate rightsizing has changed the structure and culture of most organizations, and hence, project management. More flexible and temporary interdepartmental(不同部门间）teams that are given greater responsibility and authority for the success of organizations have replaced rigid hierarchical command structures and permanent teams. Contemporary system development methodologies depend on having teams that include both technical and nontechnical users, managers, and information technologists all directed to the project goal. These（ ）teams require leadership and project management.A.activities B.tasks C.services D.softwareA.document B.order C.specification D.authorityA.process B.activity C.step D.taskA.predefined B.acceptable C.rigid D.StrictA.invariable B.fixed C.permanent D.dynamic
材料：The field current supply in older machines comes from a lower voltage direct current generator or exciter on the same shaft as the alternator. Modern machines however are either statically excited or of the high-speed brush-less type. The exciter is required to operate to counter the effects of power factor for a given load. The power factor is a measure of the phase difference between voltage and current and is expressed as the cosine of the phase angle. With a purely resistance load the voltage and the current are in phase, giving a power factor of one. The power consumed is therefore the product of voltage and current. Inductive or capacitive loads, combined with resistance loads, produce lagging or leading power factors which have a value less than one.The power consumed is therefore the product of current, voltage and power factor. The alternating current generator supplying a load has a voltage drop resulting from the load. When the load has a lagging power factor this voltage drop is considerable. Therefore the exciter, in maintaining the alternator voltage, must vary with load current and also the power factor. The speed change of the prime mover must also be taken into account.问题： The word “machines” in the passage refers to _____.A.the direct current generatorB.the alternating current generatorC.the exciterD.the prime moverWhich of the following statements is true according to the passage ?A.With a purely resistance load, the power factor is zeroB.Inductive loads combined with resistance loads produces leading power factorsC.Capacitive loads combined with resistance loads produces lagging power factorsD.With a purely resistance load, the phase angle is zeroWhen the load has a lagging power factor this voltage drop is considerable. This sentence means that _____.A.with a purely resistance load, the voltage drops too muchB.there is a considerable voltage drop in the capacitive load combined with resistance loadC.when the load is the capacitive load combined with resistance load, the voltage drops to zeroD.when the load is the inductive load combined with resistance load, the voltage drop is fairly largeThe exciter must vary with: ① load current ② the power factor, ③ speed change of the prime mover.A.①B.②C.①②D.①②③请帮忙给出每个问题的正确答案和分析，谢谢！
共用题干第二篇The next big breakthrough in artificial intelligence could come from giving machines not just more logical capacity,but emotional capacity as well.Feeling aren't usually associated with inanimate（无生命的）machines, but Posalind Picard, a professor of computer technology at MIT,believes emotion may be just the thing computes need to work effectively.Computers need artificial emotion both to understand their human users better and to achieve self-analysis and self-improvement,says Picard."If we want computers to be genuinely intelligent,to adapt to us,and to interact naturally with us,then they will need the ability to recognize and express emotions,to have emotions,and to have what has come to be called emotional intelligence,"Picard says.One way that emotions can help computers,she suggests,is by helping keep them from crashing. Today's computers produce error messages,but they do not have a "gut feeling" of knowing when something is wrong or doesn't make sense.A healthy fear of death could motivate a computer to stop trouble as soon as it starts.On the other hand, self-preservation would need to be subordinate to service to humans.It was fear of its own death that promoted RAL,the fictional computer in the film 2002 :A Space Odyssey, to extermine（消灭）most of its human associates.Similarly,computers that could"read"their users would accumulate a store of highly personal information about us一not just what we said and did,but what we likely thought and felt."Emotion not only contribute to a richer quality of interaction,but they directly impact a person's ability to interact in an intelligent way,"Picard says."Emotional skills,especially the ability to recognize and express emotions,are essential for natural communication with humans." According to Picard,emotion intelligence is necessary to computers because_________.A:it can make computers analyze the information more efficientlyB:it can help to eliminate the computrs' innate problemsC:it can improve the mechanic capacity of computersD:it can make computers achieve a better understanding of human users
