And it's dying! Pando means “I spread” in Latin and it's a name that makes sense. Pando is a big group of trees that all grow from the same roots（根）. They look separate but are all connected underground by their roots. With all these roots connected, the whole group of trees can share water and food. 7 ▲. In summer, animals（mule deer and cattle） feed on the new leaves, making it difficult for the trees to grow. The number of mule deer has even increased because their natural enemies（mountain lions, bears） have disappeared. The second problem is from people. Hikers and campers like this area because of the colourful leaves in autumn. But getting too close and stepping on the new growth has made Pando smaller and thinner over the last 50 years. Protecting Pando is challenging. Putting fences（栅栏） around it to keep animals away has helped new growth. But deer are smart, and they've found ways to get through the fences. Other efforts have included cutting or burning part of Pando to encourage new growth. Pando grows back very quickly after a forest fire, and these fires do not reach temperatures that would kill its root system. Michael Grant, one of the scientists who helped name Pando, warns if the trees are in trouble, the whole ecosystem（生态系统） will be in danger too. We need to make people understand the long- term effects of our actions. 9 1. ［图片理解］Which picture is Pando? A. B. C. D. 2. Which of the following can be put in the blank ▲ in Paragraph 3? A.

To see the new leaves. B. To search for mule deer and cattle. C. To drive away the natural enemies of mule deer. D. To experience the beauty of colourful autumn leaves. 4.

To show the trouble Pando has. C. To ask people to protect Pando. D. To share ways to look after Pando. √ 12 Ⅲ. 任务型完形填空（共10小题；每小题1分，满分10分） 北极的神秘与危险 difficulty, face, than, might, break, below, seldom, both, although, hard People often think of the North Pole（北极） and the South Pole as similar frozen wastelands.
