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.

概括大意与完成句子
1 Before you can use a fax modem, you must specify it as active. Also, only one fax modem can be used at a time. If you have more than one available, you need to specify which one you want to be active. Make sure that Mail is closed and the Outbox is empty before you specify the active modem.
2 If you plan to use a fax modem located on another computer n your network, you need to specify the name of the computer and the name of the shared directory. You may also need to supply a password for the shared directory. Your workgroup administrator or the person whose fax modem it is can give you this information.
3 When you share a fax modem, anyone using the network can connect to it to send faxes. Because of this, you might receive faxes for other people in addition to faxes intended for you. You need to forward faxes intended for others.
4 You can send a fax from Mail or from an application. When you send a fax from Mail, your fax can include other documents that you attach. When you send a fax from an application, the current document becomes the fax message. You can send the same message to both Mail and PC Fax recipients at the same time by using a combination of mail and fax addresses. If you send many faxes to the same recipients, you can avoid having to type the fax number each time by adding fax numbers to your Personal Address Book in Mail.
5 You can use the Personal Address Book in Mail to store commonly used fax numbers in addition to commonly used mail addresses. You do not need to include the recipient’s name when you type a fax address. However, if you have selected the option in Mail to add recipients automatically to the Personal Address Book, and you use a name in the fax address, the address is added by name rather than by fax number.
6 You can receive a fax directly via a fax modem on your computer, or another person who has a fax modem on their computer can use Mail to forward a fax to you. In either case, incoming faxes appear exactly like incoming mail messages in your Mail Inbox. You can view a fax on your screen, print it, save it on your hard disk, reply to it or forward it.

Intelligence: a Changed View
1. Intelligence was believed to be a fixed entity, some faculty of the mind that we all possess and which determines in some way the extent of our achievements. Its value therefore, was as a predictor of children’s future learning. If they differed markedly in their ability to learn complex tasks, then it was clearly necessary to educate them differently and the need for different types of school and even different ability groups within school was obvious. Intelligence tests could be used for streaming children according to ability at an early age: and at 11 these tests were superior to measures of attainment for selecting children for different types of secondary education.
2. Today, we are beginning to think differently. In the last few years, research has thrown doubt on the view that innate intelligence can ever be measured and on the very nature of intelligence itself. There is considerable evidence now which shows the great influence of environment both on achievement and intelligence. Children with poor home backgrounds not only do less well in their school work and intelligence tests but their performance tends to deteriorate gradually compared with that of their more fortunate classmates.
3. There are evidences that support the view that we have to distinguish between genetic intelligence and observed intelligence. Any deficiency in the appropriate genes will measure innate intelligence, whereas we can observe and measure the effects of the interaction of whatever is inherited with whatever stimulation has been received from the environment. Researches have been investigating what happens in this interaction.
4. Two major findings have emerged from these researches. Firstly, the greater part of the development of observed intelligence occurs in the earliest years of life. It is estimated that 50 percent of measurable intelligence at age 17 is already predictable by the age of four. Secondly, the most important factors in the environment are language and psychological aspects of the parent-child relationship. Much of the difference in measured intelligence between “privileged” and “disadvantaged” children4 may be due to the latter’s lack of appropriate verbal stimulation and the poverty of their perceptual experiences5.
5. These research findings have led to a revision in our understanding of the nature of intelligence. Instead of it being some largely inherited fixed power of the mind, we now see have to be learned and, indeed, one of them is learning how to learn.
6. The modern ideas concerning the nature of intelligence are bound to have some effect on or school system. In one respect a change is already occurring. With the move toward comprehensive education and the development of unstreamed classes6, fewer children will be given the label “low IQ7” which must inevitably condemn a child in his own, if not we can teach the reading or arithmetic is accepted by more and more people.
词汇：
entity n. 存在，实体
stream v. （根据能力把学生）分组
innate adj. 内在的
interaction n. 相互作用
stimulation n. 激发，促进
注释：
1、…research has thrown doubt on the view that innate intelligence can ever be measured and on the very nature of intelligence itself. : … … 科学研究对内在智力可以衡量这一观点以及智力的实质本身都表示怀疑。
2、distinguish between genetic intelligence and observed intelligence: 区别基因智力和习得智力
3、the interaction of whatever is inherited with whatever stimulation has been received from the environment: 遗传所得和从环境所得到的激发两者之间的相互影响，这里的两个whatever 都相当于what, 都引导了名词性从句，分别作介词of 和with 的宾语。
4、“privileged” and “disadvantaged” children : “有优势的”和“没有优势的”孩子，privileged 原来的解释是“有特权的”，disadvantaged 是“不利的”，实际上它们分别用于指家境富裕和家境贫困、尤其是黑人家庭的孩子。
5、lack of appropriate verbal stimulation and the poverty of their perceptual experiences: 缺乏必要的语言刺激以及感性经历贫乏
6、comprehensive education and the development of unstreamed classes: 综合教育以及混合编班的做法，comprehensive education 指具有不同能力的学生同在一校的，综合的教育制度，和后面的development of unstreamed classes 是一脉相承的。
7、IQ：智商，IQ是Intelligence Quotient 的缩写。
8、condemn a child in his own, if not society’s eyes: 哪怕社会不把孩子看扁，他自己也把自己看扁了，condemn 这个动词是“谴责，判定… … 不合适、不足”的意思；in one’s eyes 是“在……的眼里”。
