When we were little kids, we knew about traffic lights. The color red means stop, the color green means go and the color yellow means slow down or show some caution (小心). But why are these colors used for traffic lights? Why couldn't they be colors like blue, brown or orange? Here is the history of the colors for traffic lights.
Well, it's important to know that before there were traffic lights for cars, there were traffic signals (信号) for trains. At first, railway companies used red to mean stop, white to mean go and green to mean caution. But train drivers had a few problems with the color white meaning go. They could easily mistake stars at night for the signal to go. So railway companies moved to the color green to mean go, and the color yellow to mean caution.
The color red has a lot to do with danger. Red is the color with the longest wavelength (波长), so it can be seen from a greater distance than other colors. The color yellow is used to mean caution because it has a little shorter wavelength than red, but not as short as green.
Believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because they were easier to see in poorly-lit areas. But people once again used red to mean stop after more highly reflective (反光) materials were developed. Since yellow can be seen well at all times of the day, school zones and school buses continue to be painted yellow.
Traffic lights really came a long way.

Even kids know that we should wait for the traffic light to turn green before crossing a road, but not everybody follows this basic rule.
“Chinese style road crossing” has become a hot expression recently. Chinese people “cross roads without thinking about traffic lights, so long as（只要）they are part of a crowd”, said a post on Sina Weibo.
A CCTV news program showed that in only an hour, more than 600 people jumped red lights when crossing a road at a crossing in Shijiazhuang, Hebei.
Many people say that they jaywalk（乱闯马路）because the red light lasts too long. Such an opinion is supported by a research team at Tongji University. The team did research on people’s waiting times at different road crossings from 2008 to 2010. They found that Chinese people would wait for 70 to 90 seconds before they lost their patience. “People are likely to ignore(忽视) the light when the waiting time is longer than they can stand,” said Ni Ying, a member of the research team.
However, a survey on Sina Weibo suggested that half of the respondents（调查对象）believe that people jaywalk mainly because they disregard（忽视）rules.“I always obey traffic rules. Time is important but safety should come first,” wrote “Qixiaoe” on Weibo.
Many countries give out punishments to jaywalkers. In Singapore, the maximum(最大量) can be three months in prison. Some Chinese cities have started taking some actions, too. For example, the first three people in a jaywalking group will be fined 50 yuan in Shijiazhuang.
But calling on people to respect rules is more important. To completely solve the problem, everyone should realize the importance of obeying the traffic rules.
1. Which of the following is the “Chinese style road crossing”?
A. To wait for the traffic light to turn green.
B. To cross a road slowly.

2.What does the phrase “the team” in Paragraph 4 refer to (指的是)?
A. A CCTV news program.
B. A research group at Tongji University.
C. A post on Sina Weibo.
D. A daily newspaper.
3. How long will Chinese people wait to cross the road before they lose patience?
A. Less than one minute.
B. About five minutes.
C. Less than one and a half minutes.
D. More than ten minutes.
4. Why do people jaywalk according to the survey on Sina Weibo?
A. Because there are too many people on the road.

C. Because people don’t pay much attention to rules.
D. Because people have less patience.

What happens to a teenage kid when the world he thought he knew suddenly changes? Find out in Little Brother by American author Cory Doctorow. It is a fascinating book for a new generation of science fiction readers.
Marcus Yallow, 17, from San Francisco is much more comfortable in front of a computer than obeying the rules of society. Smart, fast and wise to the ways of the networked world, he has no trouble outwitting his high school's monitoring(监控) system. This way he and his friends get to head off to play a popular online game in real life.

Marcus stops a military vehicle to get help for his injured friend, but this simple act throws him into a Department of Homeland Security (DHS) secret prison.

When he returns, Marcus discovers that there are many “security measures” in place and that now all citizens are treated like potential terrorists. While some consider this government action necessary for public safety, Marcus sees this as a complete destruction of the rights he is supposed to have as a citizen.
He knows that no one will believe his story, which leaves him with only one thing to do: to take down the DHS (数字处理系统) himself. He helps organize a large network called Xnet to spread the truth, anonymously (匿名地)．
