Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed wood lands into farmland, and made lakes and reservoirs out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.
However, man’s changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles; smoke from factories pollutes the air of industrialized areas and the surrounding areas of countryside. The air in cities is becoming increasingly unhealthy.
The pollution of water is equally harmful. In the sea, pollution from oil is increasing and killing enormous numbers of algae (a very simple plant without stems or leaves that grows in or near water), fish and birds. The whole ecological balance of the sea is being changed. The same problem exists in rivers. Industrial wastes have already made many rivers lifeless.
Conservationists believe that it is now necessary for man to limit the growth of technology in order to survive on earth.
Questions 33 to 35 are based on the passage you have just heard.
33. What is the purpose of man changing his physical environment?
34. When is the ecological balance of the sea lost?
35. Who would most probably disagree with conservationists?
选项
A、When the ecological balance of the river is lost.
B、When people consume more fish than they used to.
C、When large numbers of algae, fish and birds are killed.
D、When the production of marine petroleum is increased.
答案
C
解析
选项均以When开头可知,本题考查某事发生的时间。短文中提到The pollution of water...killing enormous numbers of algae…fish and birds.The whole ecological balance of the sea is being changed,由此可知,当海水被污染,大批海洋生物死去,海洋的生态平衡也就被破坏了,故答案为[C]。
