　　Adult Education

　　1　Voluntary learning in organized courses by mature men and women is called adult education. Such education is offered to make people able to enlarge and interpret their experience as adults. Adults may want to study something which they missed in earlier schooling, get new skills or job training, find out about new technological developments, seek better self-under-standing, or develop new talents and skills.

　　2　This kind of education may be in the form of self-study with proper guidance through the use of libraries, correspondence courses, or broadcasting. It may also be acquired collectively in schools and colleges, study groups, workshops, clubs, and professional associations.

　　3　Modern adult education for large numbers of people started in the 18th and 19th centuries with the rise of the Industrial Revolution. Great economic and social changes were taking place: people were moving from rural areas to cities, new types of work were being created in an expanding factory system. These and other factors produced a need for further education and re-education of adults.

　　4　The earliest programs of organized adult education arose in Great Britain in the 1790s,with the founding of an adult school in Nottingham and a mechanics' institute in Glasgow. The earliest adult education institution in the United States was founded by Benjamin Franklin and some friends in Philadelphia in 1727.

　　5　People recognize that continued learning is necessary for most forms of employment today. For example, parts of the adult population in many countries find it necessary to take part in retraining programs at work or even to learn completely new jobs. Adult education programs are springing up constantly to meet these and other needs.

　　23　Paragraph 2 __________

　　24　Paragraph.3 __________

　　25　Paragraph 4 __________

　　26　Paragraph 5 __________ A　Necessity for developing adult education

　　D　what they did not manage to learn earlier

　　E　dates hack to the eighteenth century

　　F　mass production

　　第三部分：

　　23　C本段的主题是成人教育的不同方式。

　　24　A本段从社会、经济、工业等因素介绍了发展成人教育的必要性。

　　25　B本段介绍了早期的有组织的成人教育计划。

　　26　D本段简述了人们对成人教育的认识和成人教育的发展。

　　27　D动词learn后面缺的是它的宾语，填入的是个由what引导的宾语从句。

　　28　B including提示后面要求填入的是前面说的成人教育的各种形式中的若干种。

　　29　A has been made necessary被动式的出现说明后面很可能会跟一个by短语，当然从意义上考虑不应该是C。

　　30　E date是动词，date back to的意思是“追溯到……”。

　　第3部分：概括大意与完成句子。下面的短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第3～6段每段选择1个最佳标题;(2)第27～30题要求从所给的6个选项中为每个句子确定1个最佳选项。

　　Maglev Trains

　　A few countries are using powerful electromagnets to develop high-speed trains, called maglev trains. Maglev is short for magnetic levitation1, which means that these trains float over a guide way using the basic principles of magnets to replace the old steel wheel and track trains.

　　If you’ve ever played with magnets, you know that opposite poles attract and like poles repel each other. This is the basic principle behind electromagnetic propulsion. Electromagnets are similar to other magnets in that they attract metal objects, but the magnetic pull is temporary. You can easily create a small electromagnet yourself by connecting the ends of a copper wire to the positive and negative ends of an AA-cell battery. This creates a small magnetic field. If you disconnect either end of the wire from the battery, the magnetic field is taken away.

　　The magnetic field created in this wire-and-battery experiment is the simple idea behind a maglev train rail system. There are three components to this system: A large electrical power source, metal coils lining a guide way or track, and large guidance magnets attached to the underside of the train.

　　The big difference between a maglev train and a conventional train is that maglev trains do not have an engine-at least not the kind of engine used to pull typical train cars along steel tracks4. The engine for maglev trains is rather innoticeable. Instead of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combines to propel the trains.

　　The magnetized coil running along the track, called a guideway, repels the large magnets on the train’s undercarriage, allowing the train to levitate between 1 to 10 cm above the guideway. Once the train is levitated, power is supplied to the coils within the guideway walls to create a unique system of magnetic fields that pull and push the train along the guideway. The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity of the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust.

　　Maglev trains float on a cushion of air, eliminating friction. This lack of friction allows these trains to reach unprecedented ground transportation speeds of more than 500 kph, or twice as fast as the fastest conventional train. At 500 kph, you could travel from Paris to Rome in just over two hours.
