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.
