三、阅读理解
①Why do the leaves on trees have different colors What makes them change their colors
②Leaves use sunlight, water and air to make food for the trees. This way of making food is called photosynthesis (光合作用). Photosynthesis is important to animals as well as plants. Some animals eat plants. Other animals eat these animals.
③Summer is playtime. For the leaves of many trees, however, it’s work, work, work! The sun is shining. The leaves are making food for the trees. The trees keep more than enough food deep inside. Leaves are green in summer because they are making food. Leaves also have orange, yellow, or brown colors inside them. During summer, those colors are covered by the green color.
④Many places get colder in autumn with shorter days and longer nights. Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical (化学物质). The orange, yellow, and brown colors grow when that happens.
⑤Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves are icy while still on the trees, the trees can be hurt. Trees that drop their leaves are bare (光秃秃) in winter. They use the food they save in summer to get through the cold days and nights.
⑥Spring comes before long. Ice and snow disappear and the rains come. The sun shines, and tiny leaves grow from branches. Once again , the leaves use sunlight, water and air to make food. The cycle begins again.
