  Leaves are nature’s food factories. Plants take water from the ground through their roots. They take a gas

  called carbon dioxide (CO2) from the air. Plants use sunlight to turn water and CO2 into glucose. Glucose

  is a kind of sugar. Plants use glucose as food for energy (f&ft) to grow. The way plants turn water and CO2

  into glucose is called photosynthesis. That means "putting together with light.” A chemical called

  chlorophyll helps make photosynthesis happen. Chlorophyll is green. It gives plants their green color.

  As summer ends and autumn comes, the days get shorter and shorter. 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 on the food

  they have stored during the summer. They begin to close their food—making factories. The green

  chlorophyll disappears from the leaves. Then, we begin to see yellow and orange colors. A few of these

  colors stay in the leaves all the time. We just can’t see them in the summer, because they are covered up

  by the green chlorophyll.

  Red and purple colours we see in leaves are made mostly in the autumn. In some trees, like maples(枫树)

  ,glucose is stored in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn

  this glucose into red. The brown color of trees like oaks(橡树) is made from wastes left in the leaves.

  1. The word "chlorophyll" in the first paragraph means in Chinese.

  A.叶绿素 B.氧气 C.胡萝卜素 D.蛋白质

  二、普通阅读

  1. A 解析:文中第一段最后两句,说Chlorophyll is green. It gives plants their green color.其实是从这里

  推敲的,Chlorophyll是绿色的,排除BCD,选A.

  2. D 解析:第二行,They take a gas called carbon dioxide (CO2) from the air.选D。

  3. C 解析:第一段第三行The way plants turn water and CO2 into glucose is called photosynthesis.

  4. B 解析:根据在最后一段第一行Red and purple colours we see in leaves are made mostly in the autumn.

  5. C 解析:turn this glucose into red在倒数第二句话。

  其实,这篇文章的生单词有点多,但是并不应该影响做题,只要按照步骤来:想看题干----找关键词---

  回归原文定位位置-----选择答案,就没有问题。你是这样做的吗?
