Devra Davis was an American epidemiologist (流行病學家) and writer. In When Smoke Ran Like Water, Devra Davis takes the reader from killer smoke to the serious problems of the present including breast cancer and climate change. Davis has been devoted to decreasing illness and loss of life from environmental pollution for decades. She is determined not to let figures and numbers hide the people whose lives are in danger.
One of the things that makes When Smoke Ran Like Water, her book on the battle against pollution, so powerful is that she hasn’t just only studied the statistics (數字統計), but she’s lived them. As a child in the Monongahela River town, she survived the 1948 smog (煙霧) pollution that was reported to have killed 20 people. She writes, “The 50 people who died in the month following decade are nowhere counted. And there is no counting of the thousands called the non-killed － all those who went on to suffer in various poorly understood ways.”
For Davis, counting counts. She focuses on epidemiology, the science which is rooted in numbers. Her book is a series of related stories, which uses a convincing (具有說服力的) method to support her conclusions. For anyone interested in the future of human health, When Smoke Ran Like Water also provides a valuable basis for understanding and action.
67. We can learn from the text that Davis cares most about_____.
A. the measures taken by governments to fight environmental pollution
B. the lasting damage to health caused by environmental pollution
C. the number of people died in environmental pollution
D. the environmental pollution caused by the smog in 1948
68.The author thinks that When Smoke Ran Like Water is a powerful book because_______.
A. Davis was an expert in the study of pollution
B. Davis used real numbers to study pollution
C. Davis was good at writing interesting stories
D. Davis put her real-life experience into the book
69. What kind of method is used by Davis to support the conclusion?
A. The reasoning method B. The storytelling method
C. The statistic method D. The experiment method
70. The purpose of the text is to________.
A. show the damage caused by pollution
B. explain why When Smoke Ran Like Water is popular

Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
"Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says.

Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen.
