正确答案：
(b) Choosing the right combination of styles to manage the desired change will be an interesting challenge to John as the principal
change agent. Education and communication will be vital in getting the police officers to buy in to the need for change. It is
only by changing their perception of the nature and size of the city centre problem that any change in activity will be possible.
Communication will also be important to keep the other stakeholders informed and on board – in this case the mayor is likely
to be a key player.
Having convinced the police officers of the need for and achievability of the change John has then to motivate them to become
involved. This is achieved through collaboration and participation. John will determine the extent to which officers or task
groups are involved in various parts in the change process. Here the emphasis is on getting a shared ownership of the problem
and getting better solutions to parts of the problem. As with education and communication this may be a time-consuming
process.
Intervention by John may be needed at various points in the change process; he may delegate certain activities to others but
retain the coordination and control of the project. On occasions it may be necessary for John to take direct control over the
process in order to clarify and speed-up the whole process but such direction may cause a lack of acceptance and a poorly
conceived strategy. Finally, in times of crisis resort may have to be made to coercion/edict. This is likely to be the leastsuccessful means of managing change and should only be used when exceptional circumstances are present.

正确答案：Computer The twentieth century witnessed great changes in the whole world: economic boom industrial development and raise in people's living standards to which technological evolution contributed a lot. Among all those inventions which was the greatest one? Different people have different views. Some think the greatest invention was television while others believe it should be atom energy. But as far as I am concerned in terms of the depth of influence no other inventions can be compared with computers which would remain unrivalled even for another one hundred years. First of all computers save a great deal of effort people spend on calculating. Before computers were invented people had to calculate manually. Sometimes it took scientists weeks even months to work out a result daring the course of which they might make mistakes and the accuracy of data was in turn affected. But with the help of computers people are freed from heavy calculation. It only takes seconds to have a result which used to take weeks in the past. Moreover not only the speed but also the accuracy is improved to a large extent. Computers can also simulate different environments that can't be created in real life. In the science research sometimes scientists need to have a simulation environment to improve their theories or as a basis of further research. Without computers it would be difficult to have accurate and reliable results. But computers can make everything easy. Just input programs and data everything will be done. With computers the storage of information has become easier which in turn has increased the whole world's efficiency. At banks post offices and supermarkets people no longer need to queue for a long time because computers help the working staff increase their work efficiency — files and data stored in computers can be located in a very short time and their chances of getting lost are lowered to a large extent. Computers' influence has been further reinforced with the appearance of Internet which was developed based on the local area network (LAN) of computers. Today Internet has become the fastest developing medium in the world and you can do almost everything you need on it: communicating with friends reading news watching movies listening to music etc. But you must do all the above things on a computer. Although many other inventions of the 20th century brought great convenience to human or changed people's lives computers have the most valuable contribution to human and it will have much more contribution in the future.
