The World Health Organization 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. To help fight the problem, the WHO announced, new guidelines aimed at reducing household pollutants.

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.

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 fuel indoors. He says opening a window or door to let out the harmful air will not improve the situation. It will only pollute the outdoors.

WHO officials say indoor pollution leads to early deaths from stroke, heart and lung disease, childhood pneumonia（肺炎） and lung cancer. Women and girls are the main victims. The United Nations found that more than 95 percent of households 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 cook-stoves and other equipment to burn fuels in a more efficient way.

WHO experts note some new, safe and low-cost technologies that could help are already available. In India, you can buy an induction(电磁) stove for about　 $ 8.00. And in Africa a you can buy a solar lamp for less than $ 1. 00.

Vitamin B could help lessen the effects of the most dangerous type of air pollution，according to a new study published recently. In the first study of its kind，a team of international researchers looked at the damage caused by one of the pollutants that has the most severe impact on health: PM2.5.

Particulate matter，or PM，is a type of air pollutant consisting of small particles of different sizes. PM2.5 has a diameter of fewer than 2.5 micrometers，about 30 times smaller than a human hair. These particles are so small that they can go into our respiratory system (呼吸系统), resulting in lung and systemic inflammation (炎症) and stress.

The team found that something as simple as a daily vitamin B supplement could potentially reduce the impact of the tiny particles on the human body，although they stressed that the research was in its early stages and the sample size was small.

For this study，10 volunteers were initially exposed to clean air and given a placebo (安慰剂) to check their responses. The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Toronto，where an estimated 1，000 cars pass every hour. The bad air was delivered to the volunteers through an “oxygen－type” face mask. The experiment was then repeated，with each volunteer taking a vitamin B supplement daily made up of 2.5 mg of folic acid，50 mg of vitamin B6，and 1 mg of vitamin B12. B6 can be found in liver，chicken and nuts，and B12 in fish，meat，eggs，milk and some cereals.

The researchers found that four weeks of vitamin B supplements reduced the damage of PM2.5 exposure by 28%－76%. The results highlight how prevention at an individual level could be used to fight the harmful effects of PM2.5.

1.Why is PM2.5 harmful to our health?

A.It pollutes and poisons the air. B.It is too much to be got rid of.

C.It carries viruses and diseases. D.It is easily breathed in and damages our body.

2.What can we infer from Paragraph 3?

A.The process of the research was not scientific.

B.This kind of research has been done many times.

C.Further studies are needed to confirm their findings.

D.Vitamin B is hard to obtain in people’s daily life.

3.What is the text mainly about?

A.International researchers have a new finding.

B.Vitamin B could reduce the damage of PM2.5.

C.Particulate matter does great harm to our health.

D.Emission control and regulation are badly needed.

4.The new study was probably published ________.

A.in a science journal B.on a government website

C.in a fashion magazine D.in a medical textbook

According to the WHO, 92% of the world's people are living in places where the PM2.5 level goes beyond the recommended level. So it’s urgent to find a solution to the problem.

According to this study, published in the PNAS, 10 volunteers were initially exposed to clean air and given a placebo (安慰剂）to check their baseline responses. The group then kept on taking placebos tor tour weeks before being exposed to heavily polluted air from downtown Toronto, where an estimated 1,000 cars passed every hour. The bad air was delivered to the volunteers through an "oxygen type" face mask. The experiment was then repeated, with each volunteer taking a Vitamin B supplement daily, made up of 2.5mg of folic acid, 50mg of Vitamin B6, and l mg of Vitamin B12.

Vitamin B6 can be found in liver, chicken, nuts and other things, and Vitamin B12 in fish, meat, eggs, milk and some cereals. The researchers found that four weeks of Vitamin B supplements — the damage of PM2.5 effects by 28-76%. The results emphasized how prevention at an individual level could be used to fight against the damage of PM2.5, the researchers said.

1.What's the newly discovered effect of Vitamin B in Paragraph 1?

A. It can be used to replace other vitamins in our daily life.

B. It can help lower the air pollution level in the open air.

The World Health Organization(WHO)has the following advice to protect yourself from being infected with the coronavirus or other flu-like diseases.

1. Clean your hands often and carefully with an alcohol-based hand cleaner or wash them with soap and water. Washing your hands kills viruses that may be on your hands.

Keep social distancing.　 2. When someone coughs or sneezes, he releases small drops of liquid from his mouth or nose which may contain the viruses. If you are too close, you can breathe in the liquid, including the COVID-19 virus if the person coughing has the disease.

Avoid touching eyes, nose and mouth. Your hands touch many surfaces where viruses can survive up to nine days. Once contaminated(弄脏), hands can carry the viruses to your eyes, nose or mouth. 3.

Promote respiratory hygiene(呼吸道卫生). Make sure that you cover your mouth and nose with your elbow or facial tissue when you cough or sneeze. 4.

If you have a fever, a cough and difficulty breathing, seek medical care early. Stay home if you feel unwell, even with mild signs of infection such as headache and slight runny nose, until you recover. If you have a fever, a cough and difficulty breathing, seek medical attention, and follow the directions of your local health official. 5. This will also help to prevent possible spread of the coronavirus and other viruses.

A.Wash your hands frequently.

B.Then throw away the used tissue in a specially provided dustbin immediately.

C.If not, you are bound to be in a horrible condition.

D.Stay home and never participate in any social activities.

E.From there, the viruses can enter your body and can make you sick.

F.Stay at least one meter away from anyone who is coughing or sneezing.

G.Calling ahead will permit the health official to quickly direct you to the right health facility.
