Spider Monkeys – The Acrobats of the Rainforest

Spider monkeys are one of the most amazing animals in the rainforest. 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.

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.

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.
