2026年同步导学与优化训练八年级英语上册人教版第68页答案
20th May is World Bee Day. It is a day to let people know about the importance of bees in our life. When bees fly from plant to plant, they carry pollen. The pollen makes new plants grow.
There are three kinds of bees: workers, drones(雄蜂) and the queen. The queen bee is larger and longer than other bees. Her job is to lay eggs(产卵). She doesn't find food by herself. The worker bees take care of her. The drone bees are lazy. They don't work at all. Worker bees are very smart and hard-working. They can fly 10 to 15 kilometres to look for food every day. But they never get lost. They work together to build their living place.
Do you know the life of bees? The queen bee lays an egg. After three days, the larva comes out of the egg. The larva looks like a white grub. It needs to eat more food to grow. Seven days later, the larva grows into a pupa. It starts to grow the body parts. After 11 days, the pupa becomes an adult bee. Most bees have short lives. They usually live for 60 to 65 days.
The number of bees has decreased in recent years, so people are using technology to help save the bees. Scientists will make robot bees to help feed and look after the queen bee. This will get the queen bee to lay more eggs and have more bees.
26. Why do people set up World Bee Day?
A. Because bees are in danger.
B. Because bees can give us honey.

D. Because bees are very hard-working.

A. The worker bee.
B. The queen bee.
C. The drone bee.

28. What is the right order of the bee's life?
A. egg→pupa→adult bee→larva
B. egg→adult bee→pupa→larva
C. egg→larva→pupa→adult bee
D. egg→pupa→larva→adult bee
29. What's the meaning of the underlined word "decrease" in the last paragraph?
