七、(跨生物·鸟类与昆虫)阅读表达。
Hummingbirds(蜂鸟)are small birds with beautiful feathers(羽毛). They can stay still(静止的)in the air and fly backward. This makes them special among all the birds. They live in warm places with many kinds of flowers. They help plants grow by carrying pollen(花粉)between flowers.
Even though they are small，hummingbirds eat a lot. Their hearts run fast，so they need lots of energy. To have enough energy，they eat almost all day long. They often drink sweet water from flowers with their long，thin mouth.
Hummingbirds travel far to find good homes. Some go from North America to Central America each year. Soon after they build their homes，female hummingbirds lay eggs. Their eggs are very small. Baby birds come out after two weeks. Their mums bring back the food and feed them.
We should protect hummingbirds by keeping their homes safe. People can also put out bowls with sweet water to help them get enough food during warm times.
1. What makes hummingbirds special among all the birds?
2. Why do hummingbirds need lots of energy?
3. How can you protect hummingbirds?
