It is also called the monkey bread tree, the bottle tree or others.The baobab tree is a strange looking tree that grows in Africa and Australia. Just like its name “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 tree is called “the tree of life”, because it can live longer than 1,000 years old. In the dry land, the baobab tree 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. 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. Some people could hardly live without it.( )4.

A Special Tree—the BaobabCThere is almost no water in the desert (沙漠), but many animals can live in it. How do these animals get water and stay alive?Everything is hot and dry in the daytime, but the night is cold. Plants often have dew (露水) on them in the early morning. This is because cold air can’t hold as much water as hot air. Small insects can drink the dew, and bigger animals eat the plants with the dew on them.Some small animals get water from the bodies of insects. Bigger animals get water from the bodies of small animals. For example, there is a North American bird called roadrunner (走鹃). It runs fast and catches small snakes, lizards and scorpions.Some animals can wait many years for water. When the rain falls, baby shrimps (虾) come out of theireggs. They grow quickly and lay new eggs. Then the water dries up, and the shrimps die. But the new eggs do not die. They wait in the ground for the next rain. They can wait for 50 years.Most big animals can’t live in the desert because they need a few litres (升) of water every day. They can’t keep water in their bodies for a long time. But camels are different. They can drink 90 litres of water in ten minutes, and then drink nothing for a week.( )8. Insects can drink _______.A. when there is dew B. when the sun goes downC. when bigger animals eat D. when the night comes( )9. The roadrunner doesn’t eat_______ .A. snakes B. lizards C. insects D. scorpions( )10. [新考法信息组合]Which of the following are the ways that desert animals get water?① Small insects drink the dew on plants in the early morning.② Bigger animals get water by eating plants with dew.③ Small animals get water from the bodies of bigger animals.④ Camels drink a large amount of water at one time and then don’t drink for a week.A. ①②③ B. ①②④ C. ①③④ D. ②③④( )11. Which is TRUE according to the passage?A. Without water, the shrimps and their eggs can’t live.B. Most of the big animals, like camels, need water every day.C. Bigger animals get water from the bodies of insects and small animals.D. Hot air can hold more water than cold air.DSwifts (雨燕) live mostly in the air. These small birds are among the fastest animals on Earth. In fact,swifts can go two or three days without touching the ground! To get used to life in the sky, swifts use their speed and the saliva (唾液) in their mouths.Swifts can fly faster than 100 miles per hour. That’s because their wings are like boomerangs. This shape of the wings helps them to fly much faster. They can also move one wing faster than the other, which allows them to make sharp turns without slowing down. Making fast, sharp turns helps swifts catch flying bugs to eat.The saliva helps swifts catch bugs to feed their young. It is sticky, like glue. Swifts often fly into clouds of bugs such as mosquitoes and open their wide mouths to catch as many insects as they can. The bird collects insects in its mouth gradually and holds the insects in a sticky ball of saliva. One food ball can contain nearly 1,000 bugs.Swifts also use their saliva as glue to build their nests. The birds catch feathers in the air and stick the feathers together to build a strong nest on the side of a building. Swifts’ short feet are not good for walking or standing on land for long. But their sharp claws allow them to stick to rocks and walls so they can take a brief rest before returning to the sky.( )12. The second paragraph mainly talks about _____.A. how fast swifts can fly B. why swifts can fly and turn so fastC. why swifts make sharp turns D. how swifts turn around in the sky( )13. What does the underlined word “It” refer to in Paragraph 3?A. The glue. B. The swifts. C. The bugs. D. The saliva.( )14. Which of the following is TRUE about swifts?A. Swifts can’t walk for a long time because of their short feet.B. Swifts can fly for a long time because of their small bodies.C. Swifts don’t usually live on land because of their wings.D. Swifts can catch nearly 1,000 bugs in one go with the saliva.( )15.

Maybe not, but there are many plants that eat meat. Some of them are big, and they can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草).The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly (苍蝇) touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses (压) the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.Plants are living things that have leaves and roots and grow in earth. Most plants get what they need from the sun, the air and the ground. In some places, the ground is very poor. It doesn’t have all these important things, especially nitrogen (氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea!41. Where does the Venus flytrap grow?_________________________________________________________________42.
