         Birds live in trees. Squirrels(松鼠)live in trees. But did you know that some frogs(蛙)live in trees, too?
    The tree frog is hard to find. It can change colors. On green leaves, it stays green. On a brown branch(树枝), it turns brown. Some tree frogs can change from green to gold or blue.

         Tree frogs have legs and wide feet. They have sticky pads(粘性的肉趾)at the ends of their toes. These sticky toe pads keep the tree frogs from falling. Tree frogs have different colors and markings(斑点)on their skins. Their eyes are different, too. Some have green eyes, and others have bright red ones.

    (B)

         Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s chance in million.

         People have made a survey of colors of more than four thousand kinds of flowers and found that only eight of them are black.
    As we know, sunlight is formed (形成) by seven different colored lights. The wave length (波长) of each light is different, so the quantity (量) of heat in each light is also different. Flowers especially their petal (花瓣), are easy to be harmed (伤害) by high temperature.

         Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely (很少) survive (挺过) sunlight. But red flowers, orange flowers and yellow flowers can protect (保护) themselves from sunlight by reflecting (反射) the red light, orange light and yellow light, each of which has a large quantity of heat.
