Outdoor air pollution leads to more than 3 million premature deaths each year, and more than two thirds of them occur in China and India, according to new research. The authors estimate that without government intervention, the total number of deaths could double by 2050.

The study, published in the journal Nature, identifies particulate matter(悬浮微粒) as the prime pollutant leading to premature mortality. Particulate matter, a substance formed as a combination of different materials released into the air, is thought to be harmful to human health once it exceeds 2.5 micrometers in diameter. Researchers also identified ozone as a contributor to dangerous air quality.

The causes of air pollution vary dramatically from place to place. In India and China, the study says, emissions from residential heating and cooking drive air pollution by creating unhealthy quantities of smoke. Overall, residential heating emissions cause one third of air pollution-related deaths worldwide.

In highly regulated areas, like the United States, Europe and Japan, emissions from agriculture tend to be primary contributors to air pollution. Fertilizer used in agriculture releases ammonia into the atmosphere, a process that creates harmful particulate matter. Globally, air pollution from agriculture kills more than 600,000 people annually, the study finds.

The findings are consistent with a 2014 report from the World Health Organization that suggested that 7 million deaths occur annually due to both indoor and outdoor air pollution.

The study’s conclusions give a sense of urgency to efforts to reduce air pollution but present challenges because of difficulty regulating heating activity in people’s homes, according to study author Jos Lelieveld. People who live in the most affected areas should be provided with information about less toxic heating methods, he said.

“It’s important to reduce emissions from residential energy use,” Lelieveld said on a conference call for journalists. “You can’t ask people to stop eating and cooking, but you can provide better technologies.”

Air pollution contributes to a variety of ailments that eventually lead to premature mortality like lung cancer, stroke and heart failure, according to the study. Another study published this week in the journal Environmental Health Perspectives reached similar conclusions showing the devastating (毁灭性的) effects of pollution on individual health. Researchers found that chronic exposure to particulate matter increases the chance of early death by 3%. That risk is especially high for heart disease; the chance a person will die of heart disease increases by around 10% with chronic exposure to particulate matter.

Researchers found that the number of deaths is expected to double by 2050 without new government policies. Nearly all of the increase will occur in Asia, according to the report.

1.Which of the following contributes to the air pollution?

A. Particulate matter. B. Ozone.

C. Smoke D. Both A and B.

2.Which of the following is NOT true?

A. Residential heating emissions cause two thirds of air pollution-related deaths worldwide.

B. 7 million deaths occur annually due to air pollution.

C. Air pollution from agriculture kills more than 600,000 people annually.

D. The causes of air pollution vary dramatically from place to place.

3.What might air pollution lead to?

A. Lung cancer. B. Stroke.

C. Heart failure. D. All above.

4.What can be inferred from the article?

A. Residential energy use should be stopped.

B. Chronic exposure to particulate matter increases the chance of early death by 3%.

C. The number of deaths is expected to double by 2050 due to air pollution.

D. It is urgent for the government to take action.

20.A. Inspiration B. Instruction C. Introduction D. Information

Imagine what you could do with a machine that could make things disappear.

For inspiration, you could read some books. In the books of J.R.R. Tolkein, Bilbo Baggins finds a ring that can make him disappear. Of course, there’s also poor Harry Potter, who used his invisibility cloak (隐形斗篷) to hide from danger.

Now that you’ve got some ideas, it’s time for the hard part: building the cloak. To do that, you have to give up science fiction and turn to real science. An invisibility cloak has to cheat anything or anyone who might be watching. In order to understand how something can be seen, it’s important to understand how we see.

Human beings can only see objects that reflect (反射) light waves. These waves enter the eye and are then processed by the brain. However, if an object doesn’t reflect light, then the waves don’t enter the eye, and the brain doesn’t process. So building an invisibility cloak is building something that doesn’t reflect light.

Cummer was part of a team of scientists from Duke University, including David Smith and David Schurig, who built the world’s first version (版本) of an invisibility cloak. They had been inspired by the work of a British physicist, John Pendry. He in May said that an invisibility cloak was possible and Pendry was not the only one thinking about a disappearing act. At the same time, a Scottish physicist, UIf Leonhardt published a paper on building invisibility equipment.

“It wasn’t easy,” says Cummer. “As often happens in science and research, it didn’t work very well the first time. That first cloak didn’t work like Harry Potter’s --- the scientists didn’t actually see anything disappear. So the research is still under way. ”

1.The first two paragraphs serve as a (n) ________.

A. introduction B. explanation

C. comment D. summary

2.Cummer and other scientists got the idea of building an invisibility cloak from _________.

A. the film Harry Potter

B. the work of a British physicist

C. a paper published by a Scottish physicist

D. the book of J.R.R. Tolkein

3. From the text we learn that the research on an invisibility cloak __________.

A. was led by Pendry

B. was very successful

C. was used in most popular movies

D. is still in progress

4.What can be the best title for the text?

A. The Science of Disappearing

B. The Hardest Part of Building a Cloak

C. The Invention of an Invisibility Cloak

D. Turn Science Fiction into Real Science
