八、阅读表达
Can a cricket really tell you the temperature outside? Do fish know if it’s going to be a cold winter? You may hear that groundhogs can predict (预测) the end of the winter. Some of the sayings, like “If a cat sits with its back to the fire, hard weather can be expected.”, may sound unbelievable, but some may be true. Many animals do have stronger senses than humans.
Do animals tell us when a storm is coming? Birds react to the drop in air pressure (气压) before a storm by flying low. Insects stay close to the ground and wolves howl because their ears can sense the pressure change. A good rule is that you probably should be careful with the environment (环境) around us when animals act strangely.
Do you know the sound of crickets’ chirping (鸣叫) can tell you how hot the day is? Crickets are cold-blooded, so when the temperature in the air changes, the cricket’s body temperature changes with it. As the temperature rises, the cricket’s metabolism (新陈代谢) increases. When the heat rises, the cricket chirps. To get the exact temperature in degrees Fahrenheit (℉), count the number of chirps in 14 seconds, and add 40.
Do you have a tried and true weather animal that predicts the weather?
1. Why can some animals know the weather change?
2. What do birds do before the storm?
3. When should we be careful with the environment?
4. What can crickets’ chirps tell us?
5. What can be the title for the passage?
