Bats
Bats are the only mammals that can fly. Their wings are made of thin skin stretched between long finger bones. Most bats come out at night. They find their way by making high squeaks. The squeaks bounce off things and come back. The bat listens to the echo and knows what is ahead. Many bats eat insects. One small bat can eat a thousand insects in a night.

- 4. What is an "echo"?
What Roots Do
Roots grow down while the stem grows up. They do two jobs. First, roots hold the plant in the ground. A tall tree in a storm stays up because its roots spread wide under the soil. Second, roots drink. Tiny hairs on the roots take in water from the soil. The water travels up the stem to the leaves. A plant with damaged roots wilts, even if it is watered.
- 1. The author says a plant with damaged roots wilts. What reason is given?
- 2. What takes in water from the soil?
- 3. Which way do roots grow?
