History is full of examples of leaders joining together to meet common goals. But rarely have two leaders worked together with such friendship and cooperation as American President Franklin Roosevelt and British Prime Minister Winston Churchill. They both were born in wealthy families and were active in politics for many years. Both men loved the sea and the navy，history and nature.
Roosevelt and Churchill first met when they were lower?level officials in World War One. But neither man remembered much about that meeting. However，as they worked together during the Second World War they came to like and trust each other. Roosevelt and Churchill exchanged more than one thousand seven hundred letters and messages during five and a half years. They met many times，at large national gatherings and in private talks. But the closeness of their friendship might be seen best in a story told by one of Roosevelt’s close advisors，Harry Hopkins. Hopkins remembered how Churchill was visiting Roosevelt at the White House one day. Roosevelt went into Churchill’s room in the morning to say hello. But the president was shocked to see Churchill coming from the washing room with no clothes at all. Roosevelt immediately apologized to the British leader for seeing him naked. But Churchill reportedly said: “The Prime Minister of Great Britain has nothing to hide from the president of the United States.” And then both men laughed.
The United States and Great Britain were only two of several nations that joined together in the war to resist Hitler and his Allies. In January,1942，twenty?six of these nations signed an agreement promising to fight for peace，religious freedom，human rights，and justice. The three major Allies，however，were the most important for the war effort: the United States，Britain，and the Soviet Union. Yet，Churchill and Roosevelt disagreed about when to attack Hitler in western Europe. And Churchill resisted Roosevelt’s suggestions that Britain give up some of its colonies. But in general，the friendship between Roosevelt and Churchill，and between the United States and Britain led the two nations to cooperate closely.

Have you ever wondered why there are so many skin colors in the world? Do you know why people living in particular areas usually have a certain color? Biology and history are the two reasons for this.
Skin contains something called melanin, which determines a person’s skin color. The more melanin a person has, the darker his or her skin will be. The amount of and the production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with less sunlight, a person’s body will produce less melanin, making the skin lighter.
Skin color is also affected by another source ---- vitamin D. humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a dark—skinned person will produce less vitamin D than a light—skinned person when they received the same amount of sunlight.
The connection between vitamin D production and skin color is clear when we look at evolution. The earliest humans lived in Africa, their dark skin produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. their skin gradually got lighter and they lost hair. Now, people living in areas with strong sunlight like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D.
Evolution has given us a rainbow of skin colors. Humans have always had melanin to determine our skin color. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin color.
