If we are driving a car or crossing a street, we will stop when the traffic lights turn red. Why do we use red rather than other colors?
As we know, scattering (散射) happens when light goes through the air. For the same media, if the wavelength (波长) is long, the scattering will be short. If the wavelength is short, then the scattering will be long.
Of all light 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 see the lights. It helps drivers slow down or stop in time. 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 light helps drivers stop in time and help prevent accidents.

A very old lady won a million dollars in a lottery(彩票). Her son and her husband heard the news on the radio.
“How are we going to tell your mother?” the man asked. “The news might kill her!”
“That’s true,” the son said. “Perhaps we’d better speak to her doctor about it. He’ll know how to bring her the news gently.”

A group of swans flew down to a beach where a crow (乌鸦) was jumping around. The crow watched them with disdain (笔试).
“You have no flying skills at all!” he said to the swans. “All you can do is to move your wings. Can you turn over in the air? No, that’s beyond you. Let’s have a flying competition. I’ll show you what real flying is!”
One of the swans, a strong young male, took up the challenge (挑战). The crow flew up and began to show his skills. He flew in circles, performed other flying tricks, and then came down and looked proudly at the swan.
Now it was the swan’s turn. He flew up, and began flying over the sea. The crow flew after him, making all kinds of comments (评价) about his flying. They flew on and on till they couldn’t see the land and there was nothing but water on all sides. The crow was making fewer and fewer comments. He was now so exhausted that he found it hard to stay in the air, and had to struggle to keep himself from falling into the water.
The swan pretended (假装) not to notice, and said, “Why do you keep touching the water, brother? Is that another trick? “
“No,” said the crow. He knew he had lost the competition. “I’m in trouble because of my pride (自大) ! If you don’t help me, I’ll lose my life...”
The swan took pity on him, and took him on his shoulders and flew back to the beach.

If you go to Finland, you’ll be surprised to find how “foolish” the Finnish people are.
Take the taxi drivers for example. Taxis in Finland are mostly high class Benz with a fare (票价) of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to, and then get off without paying your fare. And the driver would not show the least sign of worry.
The dining rooms in all big hotels not only serve their guests, but also outside diners. Hotel guests have their meals free, so their good faith is to wave their registration card to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends and dine free of charge.
With so many loopholes (漏洞) in everyday life, surely Finland must be a heaven to those who love to take “pretty advantages”. But the strange things is, all the taxi-passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. As the Finns always act on good faith and always show an attitude of “which is which” and “what is what” in everything they do, so to live in such a society has turned everyone into a real “gentleman”. In a society of such high moral practice, what need is there for people to take precautions (预防措施) against others?
【小题1】The word “foolish” probably means _____________.
