B Many people think deserts have no life because they are hot and dry. In fact, many plants and animals can live there. They have special ways to survive. A cactus is one of the best-known desert plants. It can keep water inside its thick body. Its roots grow near the ground and can quickly take in water when it rains. Because rain does not come often, storing water is very important. Desert animals also have interesting ways to live in such a hot place. Some animals sleep during the hottest part of the day and come out at night. At night, the desert becomes much cooler. This helps the animals save water and energy. The fennec fox is a small desert animal with very large ears. Its ears do more than help it hear. They also help heat leave its body. In this way, the fox can stay cooler. However, desert life is changing in some places. Human activities and changes in the weather can make life harder for desert plants and animals. Protecting these special places is important because even a dry desert is full of life. 36. Why can a cactus live in a desert? A. It needs a lot of rain. B. It can keep water inside its body. C. It grows only beside rivers. D. It has very large leaves. 37. When do some desert animals come out? A. At night.　　B. In the afternoon.　　C. At noon.　　D. Only in winter. 38.

How do the large ears help the fennec fox? A. They help it fly. B. They help it find water. C. They help it stay cooler. D. They help it sleep longer. 40.
