Long ago, when the god first planted a tree in the garden, it was full of energy and kept moving. Then the god pulled (拔) the tree out and planted it upside down (颠倒) to make sure it stayed in one place. What’s the tree It’s the baobab tree, also called the monkey bread tree, the bottle tree or others.
The baobab tree is a strange-look tree that grows in Africa and Australia. Just like its name “the bottle tree”, it looks like a large bottle. Some grow as tall as a 16-floor building. During the dry season, these trees are standing there without leaves, and look like trunks (树干) sticking up in the air. But when the rainy season comes, leaves appear and then flowers come out. Later, the flowers can turn into fruit.
The baobab is called “the tree of life”, because it can live for more than 1,000 years. In the dry land, the baobab can pull in and hold 1,000 gallons of water. Thirsty people can drink the water stored in the tree. The fruit, monkey bread, is good to eat. Baobab leaves are a kind of medicine (药). People can use the bark (树皮) to make paper or cloth. When a baobab gets old, its trunk becomes hollow. An old tree can hold many people. The local people often build their houses inside these trunks. It is such a useful tree that some people can hardly live without it.

六、任务型阅读
阅读下面短文，根据短文内容回答问题（注意每题答案不超过8个词）。
The monarch butterfly (帝王蝶) is famous for its incredible migration. Every fall, millions of monarchs fly up to 4,000 kilometers from Canada and the northern United States to central Mexico. They spend the winter in warm mountain forests before flying back north in spring.
This migration is one of nature’s greatest wonders. But monarchs are in trouble. Their population has dropped by over 80% in the last 20 years. The main reason is habitat loss. In North America, milkweed—the only plant monarch caterpillars eat—is disappearing due to farmland expansion and herbicide (除草剂) use. In Mexico, illegal logging (伐木) threatens their winter homes.
Monarchs are important pollinators (传粉者). They help fertilize many wild plants and crops. Without them, ecosystems would suffer. Scientists are studying monarch migration to understand how they navigate (导航)—they use the sun, magnetic fields, and even scent (气味) to find their way.
You can help monarchs! Plant milkweed and nectar-rich flowers in your garden. Avoid using pesticides (杀虫剂). Support organizations that protect butterfly habitats. Educate others about the importance of monarchs. Every small action helps these beautiful insects continue their amazing journey.
74．Where do monarch butterflies spend the winter
75．How far can monarchs migrate
76．What is the main reason for the drop in monarch population
77．What do monarch caterpillars eat
78．How can we help protect monarch butterflies (Give ONE example)

79．例文
Ladies and gentlemen,
Welcome to my hometown! I'm glad to be your guide today. We will see lovely pandas soon. Now let me tell you something about pandas.
Pandas are white and black. They are very cute and friendly to people. They feed on bamboo. They mainly live in some forests and mountains. They are a symbol of friendship.
Now the number of pandas is becoming smaller and smaller, because people cut down many trees and they cannot find enough food and don't have enough space to live in. So the government is taking action to protect them, such as building research bases, teaching people about the importance of saving pandas.
