This Is Why Traffic Lights Are Red, Yellow, and Green
Ever wondered why blue doesn’t mean go and brown mean stop?1..
The idea that red means stop and green means go has impacted our lives in more ways than just traffic signals. We have been taught from a young age that the color red means danger.2.. But why were those particular colors chosen for traffic lights in the first place? For something we have to look at every day, why couldn’t they have been prettier colors like magenta(紫红) and turquoise (天蓝色)?
It’s important to know that before there were traffic lights for cars, there were traffic signals for trains. At first, railroad companies used red to mean stop, white to mean go, and green to mean caution. As you could imagine, train conductors ran into a few problems with the color white meaning go— 3., with train conductors thinking they were all clear when they really weren’t. Railway companies eventually moved to the color green meaning go, and it’s been that way ever since.
As far as red goes, that’s always been a color that indicated danger, long before cars were even around. Red is the color with the longest wavelength. 4.. The color yellow was used to caution drivers because it has a slightly shorter wavelength than red, but not as short as green.
5.. Employ these driving rules first and know that traffic lights have certainly come a long way.
A. And the color green means it’s OK to move forward
B. Turns out, there’s a perfectly good explanation for it
C. It can be seen from a greater distance than other colors
D. bright white could easily be seen from a distance by us
E. bright white could easily be mistaken for stars at night
F. Why don’t we use blue to mean go and brown mean stop
G. So don’t get mad next time you’re impatiently waiting at a traffic light
It hurts to keep secrets. Secrecy (保密) is associated with lower well-being, worse health, and less satisfying relationships. Research has linked secrecy to increased anxiety, depression, symptoms of poor health, and even the more rapid progression of disease. There is a seemingly obvious explanation for these harms: hiding secrets is hard work. You have to watch what you say.
New research, however, suggests that the harm of secrets doesn’t really come from the hiding after all. The real problem with keeping a secret is not that you have to hide it, but that you have to live with it, and think about it.
To better understand the harms of secrecy, researchers first set out to understand what secrets people keep, and how often they keep them. They found that 97% of people have at least one secret at any given moment, and people have, on average, 13 secrets.
Across several studies, researchers asked participants to estimate how frequently they hid their secret during conversations with others, and also how frequently they thought about the secret outside of social interactions. They found that the more frequently people simply thought about their secrets, the lower their well-being.
Following up this research, a new paper reveals why thinking about secrets is so harmful. Turning the question around, the consequences of telling secrets are examined. Researchers found that when a person reveals a secret to a third party, it does not reduce how often they have to hide the secret from others who are still kept in the dark. Rather, it reduces how often their mind wanders toward the secret in irrelevant moments.
Therefore, if you choose to still keep something secret, talking to another person can make the world of difference. Secrets don’t have to hurt as much as they do.
1.Which is not one of the harms of keeping secrets?
A. Being physically sick. B. Mental problems.
C. Harmed relationships. D. Hiding somewhere.
2.Why is keeping secrets so harmful?
A. Because you must hide them.
B. Because you often think about them.
C. Because it’s difficult to keep secrets.
D. Because you must watch what to say.
3.How can people reduce the harm of keeping secrets?
A. By working hard. B. By keeping 13 secrets.
C. By thinking about the secrets. D. By telling secrets to a third person.
4.Which is the text probably taken from?
A. An advertisement B. A research report
C. A biology textbook. D. A travel brochure.
