Scientists say they have evidence
that the world’s biggest freshwater
lake system is cleaning itself of
pollutants. Pollution has been a problem there for years. Yet scientists now say large amounts of chemical pollutants are disappearing from the water’s surface. A team of Canadian and American scientists reported the unusual finding.
The five Great Lakes are named Superior, Michigan, Huron, Eric and Ontario. They extend from the middle
western state of Minnesota to the eastern state of New York. Only Lake Michigan lies completely within the United States. The United States and Canada share the other four lakes. They also form part of the border between the two.
The Great Lakes form the most important island waterway in North America. The five lakes and their waterways are important to the economies of the United States and Canada.
In the new study, the scientists measured levels of several harmful chemicals that have washed into the lakes. They include chemicals to kill insects and P-C-Bs. The United States and Canada have banned P-C-Bs because of their links to cancer. Yet they are still used in some developing countries.
The study found that Lake Ontario alone released almost two metric tons of P-C-Bs between 1992 and 1995. The five lakes decreased their combined levels of P-C-Bs by about ten metric tons during the period. Levels of one banned chemical dropped by more than four metric tons.
The scientists believe the chemicals were released into the atmosphere. Keith Puckett of Canada’s environment agency worked on the project. He said the lakes are like huge lungs that have been breathing in pollutants for the past fifty years, but now it is as if the lakes are starting to breathe out again.
Mr. Puckett adds that air pollution near the Great Lakes remains a threat. He called for increased efforts to control pollution from power production centers, factories, vehicles and other causes.
1. From the passage, we can learn that______.
A. American scientists found chemical pollutants are disappearing from the five lakes.
B. the Great Lakes serve as part of the border of the two countries.
C. the US and Canada share all the five lakes
D. the use of P-C-Bs has been banned in all the developed countries
【解析】选A。细节理解题。由文章倒数第二段可知, A正确，由第二段可知B、C错误。
2. P-C-Bs are most probably______.
A. deadly diseases B. dangerous fish
C. harmful chemicals D. poisonous insects
【解析】选C。细节推断题。从第四段首句“In the new study, the scientists measured levels of several harmful chemicals that have washed into the lakes. ”得知下面谈及的都是有害的化学物质。
3. The underlined word “released” in the fifth paragraph probably means_______.
A. set free B. got rid of
C. ran out of D. gave off
【解析】选D。词义猜测题。句意为：研究发现仅安大略湖在1992年到1995年间就释放出了两公吨的P-C-Bs, 因此可推断出release的意思是“释放，排除”。故选D。
4. What is the scientists’ unexpected finding
A. Air pollution near the Great Lakes remains a threat.
B. Some developing countries are still using harmful chemicals.
C. The five lakes have been breathing out pollutants for years.
D. There has been a great reduction in some harmful chemicals in the five lakes.
【解析】选D。细节理解题。“出乎意料的发现”指的是第一段中提到的“large amounts of chemical pollutants are disappearing from the water’s surface. ”
5. What would be the best title of the text
A. A brief introduction to the five Great Lakes
B. The five Great Lakes clean themselves
C. The world’s biggest freshwater lake system
D. How to control pollution in the five Great Lakes
【解析】选B。主旨大意题。这是一则新闻报道，之所以成为新闻是因为五大湖泊有了值得关注的新发现，即：这个世界上最大的淡水系统正在自然净化，因此五大湖泊和自然净化就成了主题词，故选B。
