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 islong, 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.

Part One

    China’s worst drought in fifty years is doing harm to most of the country’s south. Hubei, Hunan, Jiangxi, Anhui and Jiangsu provinces have suffered the most because of little rain.35 million people have been affected by the big thirst, according to China’s Ministry of Civil Affairs.4 million of them cannot get safe drinking water.

    Dongting Lake in Hunan has now become smaller by two thirds. Gao Yibing, fisherman, said, “No eggs were produced, so there’s no young fish. We would not be able to fish anything in autumn and winter.”

Part Two

    Medecims Sans Frontieres, or Doctors Without Borders, is a group that helps people in need. In 1971,some French doctors and journalists formed MSF. In 1999,MSF won the Nobel Peace Prize.

    Doctors of MSF go to different countries to help poor people for free. These people are sick and hurt. They do not have enough money, food or water. MSF work in more than 70 countries including Iraq and Sudan. There are wars, disasters or diseases in these countries.

  MSF doctors treat these sick people and speak out for them. They try to tell the world about what they see in the poor countries. This makes the world pay more attention to these places.
