五、任务型阅读。
The natural world is colorful with humans, plants and animals showing different colors. Human skin can have many different colors. It changes with the sun, our feelings or our health. 1. ______ So, when we feel excited or angry, our heart can send more blood to the face and the pigments (色素) in the skin become red. This is why we have the expression that someone “sees red” when they are angry.
2. ______ Color is important for them to live on. The bright colors of flowers catch the attention of insects, which then carry their pollen (花粉) from one flower to another. Bees can see colors we can't, and they follow these to the inside of the flower. 3. ______
Animals also use color for their own need. They protect themselves with different colors so as not to be seen by predators (捕食性动物). The snowshoe hare, for example, a type of wild rabbit, changes color with seasons for this reason. During summer it has a brown color. 4. ______ However, some animals use color as a warning to make predators stay away. Bright colors such as yellow and red are often used in this way. Nature, however, is very clever, and predators also use colors to attract the animals they feed on.
So, we can see that there may be many different reasons and uses for colors in the natural world. 5. ______ But one thing is for sure: color not only makes our planet beautiful but it is also necessary for our planet to live on.
