Why do leaves change color in the fall? To answer this question, we first have to understand what leaves are and what they do. Leaves are nature's food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into oxygen（氧氣）and glucose（葡萄糖）. Oxygen is a gas in the air that we need to breathe. Glucose is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into oxygen and sugar is called photosynthesis(光合作用). That means "putting together with light." A chemical called chlorophyll（葉綠素）helps make photosynthesis happen. Chlorophyll is what gives plants their green color.

(83)隨著夏天的結(jié)束秋天的到來，天變得越來越短。This is how the trees "know" to begin getting ready for winter.

During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. ( 84)As the bright green goes away, we begin to see yellow and orange colors. Small amounts of these colors have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll.

【解析】

試題分析：這篇短文主要介紹了樹葉為什么會在變黃，這要從知道樹葉是通過水和二氧化碳，通過光合作用形成的，冬天沒有足夠的陽光和水，綠色的葉綠素從樹葉中消失。

【1】回答問題。通讀 Plants use sunlight to turn water and carbon dioxide into oxygen（氧氣）and glucose（葡萄糖）可知。故答案是Oxygen and glucose.

【2】回答問題。根據(jù)文中 A chemical called chlorophyll（葉綠素）helps make photosynthesis happen. Chlorophyll is what gives plants their green color.可知答案是Chlorophyll.

【3】英漢互譯題。本題考查as引導(dǎo)的時間狀語從句，根據(jù)比較級and+比較級，表示越來越……�？芍�是故答案是As summer ends and autumn comes, the days get shorter and shorter.
