The way we cook is important. In many countries, the two sources of heat used for cooking are natural gas and electric stoves. The World Health Organization(WHO) warns that millions of people are dying every year from indoor air pollution. The WHO finds that poor cooking, heating and lighting technologies are killing millions of people each year.

Indoor air pollution results from the use of dangerous fuels and cook stoves in the home. WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking, heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4.3 million people die from household air pollution given off by simple biomass(生物燃料） and coal stoves.

These findings show that the home use of poisonous fuels is to blame for many of these deaths. These fuels include wood, coal, animal waste and so on. Carlos Dora is Coordinator in the WHO’s Department of Public Health, Environmental and Social Determinants of Health. He says people should not use unprocessed coal and kerosene(煤油） fuel indoors. He says opening a window or door to let out the harmful air will not correct the situation. It will only pollute the outdoors. “New technologies and clean fuels can rid people of this problem.”

The United Nations found that more than 95 percent of families in sub-Saharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatemala and Peru, are also at risk.

Nigel Bruce is a professor of Public Health at the University of Liverpool. He says researchers are developing good stoves and other equipment to burn fuels in a more efficient way. “There are already many technologies for clean fuels available now. An effective and reasonably low-cost ethanol(酒精） stove that is made by Dometic is now being tested out. Another interesting development is electric induction stoves.” In India, you can buy an induction stove for about $8. And in Africa you can buy a solar lamp for less than $1.

1.How is Paragraph 2 mainly developed?

A. By making classifications.

B. By listing numbers.

C. By following time order.

D. By describing a process.

2.According to Carlos Dora, what is the best solution to indoor air pollution?

A. People should use an effective air cleaner.

B. People should open a window or door to let out the harmful air.

C. People should use new technologies and clean fuels.

D. People should prevent themselves from being exposed to harmful air.

3.What can we learn from the passage?

A. Most of the deaths from indoor pollution are in developing countries.

B. Burning solid fuels can help limit indoor air pollution.

C. People now can buy ethanol stoves made by Dometic in India.

D. There are already two technologies for clean fuels available for use.

4.Which would be the best title for the passage?

A. The way we cook is changing

B. Types of indoor air pollution

C. The development of electric stoves

D. Indoor air pollution kills millions each year

In 1917 Orville Wright predicted that "the aeroplane will help peace in many ways –in particular I think it will have a tendency to make war impossible.” Earlier in 1904, American journalist John Walker declared, “As a peace machine, the value of the aeroplane to the world will be beyond computation.” This wasn’t the first grand promise of technology. In that same year Jules Verne announced, “The submarine(潜艇)may be the cause of bringing battle to a stoppage.”

Alfred Nobel, sincerely believe his dynamite(火药) would be a war obstacle: “My dynamite will sooner lead to peace than a thousand world conventions(公约).” Similarly, when Hiran Maxim, inventor of the machine gun, was asked in 1893, “Will this gun not make war more terrible?” he answered, “No, it will make war impossible.” Gugliemo Mareconi, inventor of the radio, told the world in 1912. “The coming of the wireless time will make war impossible, because it will make war ridiculous.” General James Harbord, chairman of the board of RCA in 1925, believed, “Radio will serve to make the concept of Peace on Earth, Good Will Toward Men a reality.”

David Nye, a historian of technology, adds to the list of inventions imagined as abolishing war forever and leading to universal peace the hot-air balloon, poison gas, land mines and laser guns.

It is not that all these inventions are without benefits—even benefits toward democracy. Rather, it’s the case that each new technology creates more problems than it solves. “Problems are the answers to solutions,” says Brian Arthur.

Most of the new problems in the world are problems created by previous technology. These problems are nearly invisible to us. Every year 1.2 million people die in automobile accidents. The technological transportation system kills more people than cancer. Global warming, environmental poisons, nuclear terrorism, and species loss, are only a few of the many other serious problems troubling people.

If we embrace(拥抱) technology we need to face its costs.

1.What will new inventions do according to the first two paragraphs?

A. They will increase wars.

B. They will lead to peace.

C. They will serve people.

D. They will break conventions.

2.What does the author list so many inventions?

A. To show people’s creativity.

B. To appreciate their benefits.

C. To contradict the original ideas.

D. To prove grand promises.

3.What does the author hope to tell us about new technology through the text?

A. It will experience many tests.

B. It will bring about huge costs in the world.

C. It provides answers to many problems.

D. It presents more problems than it solves.
