Careless smokers are responsible for thousands of forest fires each year. Many of these are started when cigarette butts and matches are tossed from automobiles. Others are caused by hunters, hikers, fishermen, or woods workers who are careless in disposing of their smoking material. The Forest Service has posted rules in many of the National Forests that prohibit smoking except in certain designated areas. Many of the states have laws against throwing lighted materials from automobiles. The prevention of smoker-caused fires, however, depends upon changing the attitudes and behavior of millions of people who smoke in hazardous area.
The most important natural cause of fire is lightning. This accounts for 11 percent of forest fires on protected land for the entire nation. In the western states, lightning causes a much higher percentage of fire than it does in the east.
Advances in knowledge of fire weather are helping forest protection forces to know when to be alert for lightning-caused fires. Adequate and well-equipped forces can control them quickly and hold the damage to a minimum. Experiments in “seeding” thunder clouds to prevent or control the lightning itself have been in process for many years, but new breakthroughs are needed for any significant reduction in the lightning starts.
1. The passage is chiefly about
A. smoking in forests

Most forest fires are caused by human carelessness, negligence, or ignorance. Forest fire prevention, therefore, is mainly a problem of creating a better understanding of the importance of forests, an awareness of the danger of fire in the woods, and a sense of personal responsibility to safeguard the forests from danger. This is not an easy job. A city dweller, used to paved street, does not easily change his smoking habits when he goes into the woods.

B
Daban town is famous for girls and windmills（風車）, while Loulan is a myth（神話）in the desert. From Daban, we move to another ancient city, Loulan.
Two thousand years ago, beside the beautiful and rich Luobu Lake, there lay Loulan, ancient city on the Silk Road. Businessmen from every country gathered here and there were dancing parties. Everything shows that people in Loulan lived a rich life then.
However, two thousand years later, this rich land suddenly disappeared from the map of China. Then it became an area covered with sand and dead tree trunks.
Loulan was first “discovered” by a Swedish man Sven Hedin in 1900. People from America, Britain, Japan and Sweden, all set foot here. Then in the 1930s, a Chinese named Huang Wenbi came to Loulan for the first time. He visited and studied this area and found many relics that were beautifully and carefully made.
It is recorded that the ancient city of Loulan was the capital of Loulan Kingdom during the Han and Jin dynasties. In the past century many things have been dug out there including Han Dynasty coins, mirrors and many others from Greece and Rome. All these things show that a lot of business between East and West once took place there.
Lying on the northwest of the Lop Nur area, the Loulan Kingdom is now a lifeless area with endless “forests” of mounds（小丘）which aren’t easily seen in other parts of the world. Its mystery (神秘) has been attracting so many people from so many countries.

The African elephant,the largest land animal remaining on earth,is of great importance to African ecosystem(生態(tài)系統(tǒng)).Unlike other animals,the African elephant is to a great extent the builder of its environment.As a big plant-eater,it largely shapes the forest-and-savanna(大草原) surroundings in which it lives,therefore setting the terms of existence for millions of other animals that live in its habitat(棲息地).
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbushes,and pulls branches off big trees.This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas.In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants make open spaces,allowing new plants to grow on the forest floor.In such situations,the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species.If the elephant disappears,scientists say,many other animals will also disappear from vast areas of forest and savanna,greatly changing and worsening the whole ecosystem.
1.What is the passage mainly about?
A.Disappearance of African elephants.
B.Forests and savannas as habitats for African elephants.
C.The effect of African elephants’ search for food.
D.The eating habit of African elephants.
2.What does the underlined phrase “setting the terms” most probably mean?
A.Fixing the time.
B.Worsening the state.
C.Improving the quality.
D.Deciding the conditions.
3.What do we know about the open spaces in the passage?
A.They result from the destruction of rain forests.
B.They provide food mainly for African elephants.
C.They are home to many endangered animals.
D.They are attractive to plant-eating animals of different kinds.
4.The passage is developed mainly by ______.
A.showing the effect and then explaining the causes
B.pointing out similarities and differences
C.describing the changes in spare order
D.giving examples
