Many of us have ever loved the two toy bears-a brown Teddy bear and a yellow Winnie-the-Pooh bear. The two toy bears come froth real stories in life.
In 1902, Theodore Roosevelt, President of the USA, went on hunting. The hunting dogs found an old bear in the forest near Washington D. C. and the guide asked the president to shoot(射杀)it. But President Roosevelt disagreed. A cartoonist(漫画家)drew a cartoon showing that the president refused to shoot the bear. Soon, the bear began to appear in other newspapers. People named the bear Teddy which was Theodore's nickname(昵称).
In 1913, a captain named Harry Colebourn paid 20dollars for a black bear which was born in the Canadian countryside. The captain's hometown, Winnipeg, was the origin(起源)of the bear's name. In Winnipeg, Winnie served as the mascot(吉祥物). When World War I began, the captain went to France. Winnie was sent to London Zoo which many kids often visited. Because of its lovely look, the bear became popular with children.

①取一根粗细均匀的饮料吸管,在其下端塞入适量金属丝并用石蜡封口,塞入金属丝的目的是使吸管能在液体中。
②将吸管放到水中的情景如图乙(a)所示,测得浸入的长度为H;放到盐水中的情景如图乙(b)所示,浸入的长度为h。用ρ盐水 . ρ水分别表示盐水和水的密度,则ρ盐水与ρ水、h及H关系式是ρ盐水=。
③为了使简易密度计上两条刻度线之间的距离大一些,以使测量结果更精确,你的改进方法是。
