They are called “spider” monkeys because their long arms and legs make them look like spiders when they hang from trees. These monkeys have long, thin arms and legs, and a very long tail that can grip things. Their tail acts like a fifth hand. They can hang from branches using only their tail while eating with their hands. They are excellent climbers and spend most of their time high up in the trees. Spider monkeys live in groups of about 20 to 40 individuals. They communicate by making loud calls and using body language. They are very social animals and often groom each other to build friendships. Unfortunately, spider monkeys are endangered. Their forest homes are being cut down, and hunters catch them for food. We need to protect these wonderful creatures and their habitat. 21. Why are they called “spider” monkeys? A. Because they eat spiders. B. Because they look like spiders when hanging. C. Because they live in spider webs. D. Because they are as small as spiders. 22. What does the tail of a spider monkey do? A. It helps them swim. B. It grips things like a hand. C. It makes them look beautiful. D. It helps them fly. 23. How many spider monkeys are usually in a group? A. 5 to 10. B. 10 to 15. C. 20 to 40. D. 40 to 60. 24. Why are spider monkeys endangered? A. Because they are too friendly. B. Because their homes are being destroyed. C. Because they don’t have enough food. D. Because they cannot communicate. 25. What is the main idea of this passage? A. Spider monkeys are dangerous. B. Spider monkeys are interesting but endangered. C. Spider monkeys eat spiders. D. Spider monkeys live alone. B The Venus Flytrap – A Plant That Eats Bugs Most plants get their food from the soil and sunlight. But the Venus flytrap is different. It is a carnivorous plant that catches and eats insects! The Venus flytrap has special leaves that look like open mouths. Inside each “mouth” are tiny hairs. When an insect touches these hairs twice, the leaf snaps shut in less than a second. The insect becomes trapped. Then the plant slowly digests the bug. It takes about five to ten days for the leaf to open again. Why does this plant eat insects? It grows in poor soil that doesn’t have enough nutrients. By eating bugs, it gets the extra nutrition it needs to survive. Venus flytraps are only found in a small area of the United States, mainly in North and South Carolina. They are popular as houseplants, but they are also becoming rare in the wild. 26. What does the underlined word “carnivorous” in Paragraph 1 mean? A. 食肉的 B. 食草的 C. 杂食的 D. 有毒的 27. What happens when an insect touches the hairs twice? A. The plant grows taller. B. The leaf snaps shut. C. The insect runs away. D. The plant opens its mouth. 28. How long does it take for the leaf to open again? A. 1 to 2 days. B. 3 to 4 days. C. 5 to 10 days. D. 10 to 15 days. 29. Why does the Venus flytrap eat insects? A. Because it likes the taste. B. Because it needs extra nutrients. C. Because it doesn’t like sunlight. D. Because it wants to be famous. 30. Where can Venus flytraps be found in the wild? A. All over the world. B. Only in South America. C. In a small part of the USA. D. In Africa and Asia. C ① Did you know that ants are one of the strongest animals on Earth? They can lift objects that are 50 times heavier than their own body weight! This is like a human carrying a car. ② Ants live in large groups called colonies. A colony can have millions of ants. Each ant has a special job. Some ants gather food, some protect the nest, and some take care of the queen ant. The queen ant is the leader. She lays thousands of eggs. ③ Ants communicate by using chemicals called pheromones. They leave a trail of pheromones to show other ants where food is. This is how they work together so well. ④ Ants are also very hard-working. They spend their whole lives working for their colony. They never stop to rest for long. Their teamwork and hard work make them one of the most successful insects on Earth. 31. How much weight can an ant lift compared to its own weight? A. 10 times. B. 25 times. C. 50 times. D. 100 times. 32. What does the queen ant do? A. She gathers food. B. She protects the nest. C. She lays eggs. D. She builds the nest. 33. How do ants communicate? A. By making sounds. B. By touching each other. C. By using chemicals. D. By dancing. 34. What makes ants one of the most successful insects? A. Their size. B. Their teamwork and hard work. C. Their ability to fly. D. Their colorful appearance. 35. Which of the following best shows the structure of the passage? A. ①—②③—④ B. ①②—③—④ C. ①—②—③④ D. ①②③—④ D Did you know that plants can communicate with each other? Scientists have found that plants can send messages through the air and underground. 36. _ One way plants communicate is by releasing chemicals into the air. When a plant is attacked by insects, it sends out a special chemical. 37. _ For example, when caterpillars eat tomato leaves, the plant releases a chemical that attracts wasps. The wasps then eat the caterpillars! Plants also communicate underground through their roots. They can share water and nutrients with each other. This network is sometimes called the “wood wide web”. 38. _ They can even send warnings about diseases. So, the next time you see a garden, remember that the plants are not just sitting there silently. 39. _ They are talking to each other all the time! 从下面五个选项中选出能填入文中空缺处的最佳选项,使文章意思通顺、内容完整。 A. This chemical can warn other plants nearby. B. It’s truly amazing how they work together. C. They are actually having conversations. D. Through this network, trees can help each other. E.
