Radar is an electronic device that detects planes， ships， coastlines， landmarks， and even storm clouds． The name radar comes from the first letters of the words radio direction and ranging． As the human eye uses light waves to see， radar "sees" with radio waves． Without radar， planes could not land safely in bad weather and ships could not move safely in thick fog．1.
In the 1800s it was discovered that radio waves could be reflected from objects． But scientists did not make great advances in radar research until the 1930s， when the world was threatened by war．2.It has been used widely in almost every conflict since then．
Echoes make it possible for radar to work． When a beam of radio waves is sent out， it strikes on an object and returns an echo． This echo is picked up by radar and recorded on a screen similar to television screen． On the screen an observer sees a flash， or a blip， that shows the direction and distance of the object．3.
Airport control towers use radar to guide planes in for safe landings． Almost all large ships depend on radar to prevent collisions with icebergs or other ships．4.Weather forecasters "see" the size， direction， and speed of storms on radar screens． Astronomers can even use radar to measure accurately the distance to the moon． Thus， the device has generated major advancements．
5.Huge radar antennas have been installed all over the United States． They guard us against possible enemy attacks． We have ballistic-missiles （战略导弹）warning systems that can alert us to attacks when missiles are more than 1，000 miles away． Other radar systems warn us against enemy aircraft and even spying space satellites．
A．Police track speeders in radar-equipped cars．
B．These measurements are now highly accurate．
C．The device can be used in a wide range of fields．
D．It is therefore especially valuable to shippers and travelers．
E．During World War II many countries used radar effectively．
F．Today radar is used by commercial airliners and weather forecasters．
G．Strengthening national defense is one of radar's most important functions．
The word tolerance is widely used in liberal democracies （自由民主）． It indicates a positive meaning． Politicians urge us to be tolerant towards minorities． Educators teach us to be tolerant towards the other． The press is full of references to the need to display tolerance when faced with individuals or groups espousing a different view or holding a different religious belief． A tolerant society is an objective sought after by anyone who believes in the values of democracy． A tolerant individual is connected with virtuous qualities．
The question we must ask is whether we have been using the word tolerance fully aware of its meaning and whether we have applied it correctly to reflect what we really wish to convey．
The word tolerance means to bear， or to bear with． If I tolerate something or someone， I basically say that I am ready to bear it or him． I can tolerate a bad smell or a noisy neighbour． The act of toleration forces me to desist from conveying my objection to the existence of a phenomenon， which I find difficult to bear． A bad smell or a noisy neighbour is considered by me to be an objectionable phenomenon． By tolerating either of them， I am not transforming the bad smell or the noisy neighbour into positive phenomena． Let's be honest： I don't have a different taste when it comes to bad smells． I simply dislike it and hope that it disappears． I don't respect the noisy neighbour． I would rather have him stop at once the noise he is making so I can live in peace．
The subject tolerating is by nature not equal to the object being tolerated． If I tolerate you， I essentially say that I am above you and am prepared， although unwillingly， to bear with your presence or with your practices or opinions． That may be true in the case of an individual who is ready to tolerate the other． However， this attitude by such an individual， though empirically true， is hardly a virtue． Certainly， the fact that an individual， in reality， may merely tolerate the other or his opinion does not justify a government or any official authority promoting tolerance as a virtue． One cannot tolerate an equal being． True equality involves respect， not toleration． To respect the other as a distinctive person is hardly to tolerate him． This is the true meaning of equality： diversity existing in a mutually-respectful socio-legal setting．
A tolerant attitude involves the grant of a favour， not a right． The question we should ask ourselves is whether we would ever wish a parliament to make laws considering us， as individuals and as part of a collective entity or a permission to pursue certain actions interpreted as a favour rather than a right？ Indeed， would we ever wish anyone to listen to our views and accept us the way we are simply because he is kind enough to tolerate us？
