Ⅴ.［培优题］阅读理解
In a high mountain area in central Utah stands the world's oldest,heaviest and
largest tree,Pando. 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.#1.1
▲ 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.#1.2
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 will be in danger too. We need to make people
understand the long-term effects of our actions.#1.4

①The fastest-growing plant in the world is bamboo. Some bamboo grows so
quickly that people say they can watch it grow. The speed of growth depends on
（依赖） the type of bamboo,the earth and the season. Normal bamboo grows
30100 cm a day. It usually grows in tropical areas. It can also be found in other
parts of the world. Bamboo plants are found in Asia,parts of Africa and South
America.
②Bamboo is a wonderful plant for many people around the world. There are
over 1,000 uses for it. People make tables,clothes,and people can also eat the
shoots of it.#2
③▲ People used it because it's very strong. They used it to build
houses,boats and bridges. The Chinese made a bamboo bridge over the Min River
in Sichuan,China almost 1,000 years ago. Also,bamboo is still used to build houses
today,especially in China and the Philippines.
④Bamboo is the earliest material（材料）used to make the light bulb. The
great scientist Thomas Edison did not invent the light bulb,but he made it perfect.
He wanted the material inside to burn for a long period of time. He tried over
1,000 different types of materials. None worked very well. One day,he tried to use
a piece of bamboo and the light bulb lit up for over a thousand hours. This
invention helped other scientists to make the modern light bulb we use today.#4
