Air pollution is a leading cause of cancer and classified among top human carcinogens (致癌物质), said the International Agency for Research on Cancer (IARC), which is the World Health Organization's (WHO) cancer agency, on Oct 17,2013.“Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants,” the IARC's Dana Loomis said in a statement. “The results from the reviewed studies point in the same direction the risk of developing lung cancer is significantly increased in people exposed to air pollution.”
　　 In 2010, lung cancer resulting from air pollution killed 223,000 people worldwide, and there was also convincing evidence that it increases the risk of bladder (膀胱) cancer. Loomis said people in Asia, Eastern North America, some places in Central America and Mexico, as well as North Africa have relatively high exposure(暴露). Developing countries with large populations and booming manufacturing sectors, such as China, are particularly at risk. This week, Harbin, the capital city of Heilongjiang province, became the first Chinese city to officially suspend classes due to serious smog, really good for teachers and students.
　　 Many developed countries face similar problems, although to a lesser（较少的、次要的） degree than most developing nations. Between 91 and 96 percent of Europeans living in cities are exposed to levels of PM2.5—tiny particles with a diameter of less than 2.5 micrometers—that are higher than the WHO safety limits.
　　 Although both the composition and levels of air pollution can vary dramatically from one location to the other, the IARC said its conclusions apply to all areas of the world. “Given the scale of the exposure affecting people worldwide, this report should send a strong signal to the international community to take action without further delay,” said Christopher Wild, director of the IARC.

1.What’s the main task of IARC?

A. To focus on cancer-causing substances.

B. To evaluate the air quality.

C. To study the developing risk of cancer.

D. To send signals to the international community.

2.The underlined word “suspend” in Paragraph 2 probably means ______.

A. accelerate        　 B. acknowledge        　　

C. delay        　　 D. decline

3.Why should the international community take action without further delay?

A. A large number of people worldwide are exposed to air pollution.

B. More and more people in developing countries are exposed to air pollution.

C. Developed countries face air pollution, the level of which is higher than the safety limits.

D. The composition and levels of air pollution vary from place to place.

4.What might be the best title of the passage?

A. PM2.5，bad effect.

B. Safety limits of air pollution.

C. Signals of air pollution.

D. Air pollution, cancer risk.

Long-time exposure to air pollution can lead to physical changes in the brain and cause trouble in learning and memory, and even anxiety. This is suggested by the results of new research on mice.

While other studies have shown the harmful effects of polluted air in the lungs and heart, this is the first to show the negative effect on the brain.

The team of Laura Fonken, Randy Nelson, from the Ohio State University, USA, has spread to the brain a previous line of research which found that fine particulate (微粒) matter floating in the air mainly because of air pollution caused by humans, causes swelling in much of the body, and may be related to high blood pressure problems, and some other diseases.

In the research Fonken and his colleagues exposed mice to polluted air for six hours each day, five days a week, over a period of 10 months, almost half the average life length of mice.

Polluted air contains fine particles created by cars, factories and natural dust. Fine particles of this kind are tiny, about 2.5 micrometers in diameter, or about one-thirtieth the width of a human hair. These particles can go deep into lungs and other organs.

The concentration of this particulate material to which they exposed mice is equal to the concentration at which people can be exposed in some polluted urban areas.

After a period of 10 months, the researchers got the animals to have a series of behavioral tests. Both the behavior of mice and the results of neurological(神经的) tests done to them show that those within the polluted air had more problems in learning and memory, and higher levels of anxiety.

The results suggest that long-time exposure to polluted air can have measurable negative effects on the human brain and can cause a variety of mental health problems. This could have important consequences for those living and working in polluted urban areas.

1.The results of new research on mice first suggest that polluted air mainly does harm to ________.

A. normal organs                    B. lungs and heart

C. mental health                    D. blood pressure

2.The bad effects of tiny particles in polluted air are those except ________.

A. high blood pressure problems

B. making human hair thinner

C. different kinds of diseases

D. swelling in much of the body

3.From the last sentence we can infer that people living in polluted urban areas ________.

A. are likely to suffer from mental problems

B. can measure the negative effect on them

C. show little concern for air pollution

D. can be exposed to polluted air longer

4.Which of the following is the best title for the passage?

A. Long-time Exposure to Air Pollution

B. Evidence and Concern of Air Pollution

C. Measurable Effect on Human Brain

D. Mental Problems Caused by Air Pollution
