When the traffic lights turn red, we will stop driving a car or crossing a street. Why is red used for traffic lights instead of other colors?

As we know, scattering (散射) happens when light goes through the air. For the same media(媒质), if the wavelength is long, the scattering will be short. If the wavelength is short, then the scattering will be long.

Of all lights we can see red has the longest wavelength, so the scattering is the weakest. That means the red light travels far. In fact, it travels farther on rainy days.

Using the red light can help drivers in farther areas sec the lights. It helps drivers stow down or stop in lime. If drivers don't see the red light until they are close, they may not be able to stop the car in time. An accident may happen Red can also excite people. We can act more quickly when we see the color red. In a word, red lights help drivers stop in time and help prevent accidents.

What is language for? Some people seem to think its for practicing grammar rules and learning lists of words. Thats wrong. Language is for exchange of ideas, for communication.

The way to learn a language is to practice speaking it as often as possible. A great man once said it is necessary to practice as much as possible. And the more you use it in real situations, the more natural it will become.

Learning any language takes a lot of effort. But dont give up. Relax! Be patient and enjoy yourself. Learning foreign languages should be fun. Rome wasnt built in a day. Work harder and practice more. Your hard work will be rewarded by God one day. God is equal to everyone!

Use a dictionary and a grammar guide constantly(不断地). Keep a small English dictionary with you at all time. When you see a new word, look it up. It can help you. Think about the word—use it, in your hand, in a sentence.

Try to think in English whenever possible. When you see something, think of the English word, then think about the word in a sentence.

Practise tenses as many as possible. When you learn a new verb, learn its various forms.

Learn more about the culture behind the language. When you understand the cultural background, you can better use the language.
