八年级英语单选题简单题查看答案及解析
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 sscattering 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 places see the lights. It helps drivers slow down or stop in time. So there will be fewer accidents. Moreover, 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.
1.According to the passage, the scattering of the red light is the _______.
A. longest B. weakest C. farthest D. brightest

New traffic laws (交通法) say that if people cross the street when the light is red, they can be fined as much as 50 yuan.
The law has new rules for drivers and pedestrians(行人. Drivers have to slow down when they are close to crosswalks. If people are in a crosswalk, cars must stop to let them pass.
There are rules for bus drivers, too. If bus drivers smoke, drink or make phone calls while driving, they can be fined. Buses that carry too many people are also against the law.
Do you ride a bike to school? It’s not a good idea to carry classmates on the back. You could be fined 50 yuan. And stay in the bike lane (车道) when you’re riding. The big roads are for cars and buses.
Do you like to ride your uncle’s motorbike? When you put on your helmet (头盔), ask him to put one on, too. People on motorbikes must wear helmets, the new law says. If they don’t, they’ll have to pay 200 yuan.
Do you ride in cars often? Don’t forget to put on your seat belt (安全带), even if you’re going for a short taxi ride. It could save your life.
If you see a hit-and –run (肇事逃逸), tell the police. They may give you a reward (奖赏). And don’t be afraid to help people to the hospital if they are hurt in an accident. Don’t worry about money. The new law says that doctors must take care of them even if they can’t pay right away.
