Smog in Europe and North America could be more than 25 times more deadly than the average air pollution found in Chinese cities, a new study suggests. In the largest ever study of its kind in the developing world, researchers tested the effects of air pollution on the health of people in 272 cities in China.

They found average annual exposure to fine particles, known as PM2.5, in those cities was more than five times higher than the level recommended by the World Health Organization (WHO), according to a paper in the American Journal of Respiratory and Critical Care Medicine.

However they also discovered that it was much less likely to increase the death rate than PM2.5 in Europe and North America.

The researchers, led by Dr Maigeng Zhou, of the Chinese Centre for Disease Control and Prevention, suggested this was because China is affected by large amounts of natural dust blown by the wind from arid areas, while most pollution in the West comes from industry.

They found that for every increase of 10 micrograms of air pollution in a cubic meter of air, the mortality rate increased by 0.22 percent, discounting deaths from accidents.

Professor Frank Kelly, an expert in environmental health at King’s College London, who was not involved in the study but has studied air pollution in China, told The Independent: “Those relative risks are considerably less than those seen in Europe and the US. For mortality(死亡率) in Europe we are working on a six percent increase per 10 micrograms.” That suggests air pollution in Europe is about 27 times more toxic than average air pollution in China.

However, Professor Kelly said cities like Beijing, Shanghai and Hong Kong were likely to suffer from Western-style air pollution. "The natural dust component there is not of the magnitude that it would dwarf the coal, biomass and fossil fuel signals,” he said, “That may be true in certain cities whose pollution is not dominated by local power generation or major traffic congestion.”

Natural dust particles can cause physical damage to the lungs and trigger an asthma attack. Particles of carbon produced when fossil fuels are burned can lead to similar problems but they are also coated with toxic heavy metals, chemicals and volatile organic compounds. These are able to pass from the lungs into the blood stream where it is thought they cause further damage to the body.

Areeba Hamid, an air pollution campaigner with environmental group Greenpeace, said: “Poisonous air causes damage to people’s health wherever in the world they live. We now know fumes from diesel(柴油机) vehicles are a lot more poisonous than car companies claimed and this is a big cause of air pollution in Europe and North America. These companies have a lot to answer for, but so far they’ve managed to avoid any real accountability.”

The study of cities in China found the average annual expose to PM2.5 was 56 micrograms per cubic meter, compared to the WHO guideline limit for safe air quality of 10 micrograms.

People who were older than 75, had less education or who lived in hotter places were more likely to die. It is thought people in warmer cities were more likely to spend time outside or leave their windows open, thereby breathing more polluted air, the researchers said. They also speculated that less well educated people might have poorer access to health care or experience poorer environmental health conditions.

1.Why PM2.5 in China is less deadly than that in Europe and North America?

A. China is free from any pollution about PM2.5.

B. Pollutants affecting China mainly come from arid areas.

C. Fewer people died from PM 2.5 in China than those in Europe and North America.

D. Europe and North America are polluted by natural dust.

2.What does the underlined part in Para 7 refer to?

A. The average mortality rate.　　 B. The higher mortality rate.

C. The lower mortality rate.　　 D. The normal mortality rate.

3.What’s the real cause of air pollution in Europe and North America according to Areeba Hamid?

A. Fumes from diesel vehicles are much more poisonous.

B. The environmental agencies can’t take on responsibilities.

C. The technology doesn’t meet the standards.

D. Car companies can’t evaluate the results.

4.The author’s purpose of writing the passage is to ________.

A. appeal to people to lay an emphasis on environmental protection

B. illustrate smog in Europe and North America is quite serious

C. demonstrate China is safest place in the world to live in

D. provide some good ways to address the smog

Celebrities(名人) are more in love with themselves than the average person，according to a new study．

In case anyone needed proof, a new study supports the widely held perception：Famous people are more narcissistic(自我陶醉的)，which means they are more in love with themselves than the average person is．That is the conclusion drawn by Drew Pinsky and S．Mark Young of the University of Southern California，whose study of 200 celebrities will appear in the Journal Of Research in Personality．

It is not the entertainment industry that turns stars into narcissists，the study found．Rather, it suggests，the self-adoring(自恋的)people seek jobs in show business．The study, whose subjects were a11 celebrities from Pinsky’s‘Loveline’radio show, found that reality TV stars were the most narcissistic of all celebrities．Female stars were also more likely than the male stars to exhibit narcissistic characteristics．

It’s “common sense” that celebrities are narcissists，said Jeremy Ritzlin，a longtime Hollywood psychologist who has not seen the study．“Everyone knows famous people are really in love with themselves，”he said．“So it would be natural for narcissists to be attracted toward the stage and spotlight，where other people will also think highly of them．”

Pinsky, an assistant clinical professor of psychiatry at USC’S Keck School of Medicine，said narcissists desire attention，are overconfident，behave strangely and lack sympathy．“However, they are easily-liked，especially on first meeting，are outgoing and perform well in public，” added Pinsky, who has hosted the radio show“Loveline”for 20 years．

Celebrity guests appearing on the program were randomly chosen to participate in the study．They anonymously(匿名地)took the Narcissistic Personality Inventory test．which rates self-love levels based on seven components：superiority, exhibitionism，entitlement，vanity，authority, exploitativeness，and self-sufficiency．

1.Who are most likely to be self-adoring in the study?

A．The women stars．    B．The men stars

C．The average people．  D．It is not mentioned in the passage．

2.According to the forth paragraph．the fact “celebrities are narcissists”             .

A．is common in the entertainment industry

3.According to Pinsky, narcissists may NOT               .

We live in a sweet world. The average American kid consumes more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn’t good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to conduct a study on the negative effects of sugar. They found it could have serious effects on people’s health.

Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers.

During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice were 26% less territorial and produced 25% fewer offspring than the other mice.

Scientists often use mice for research because they have a similar genetic（基因） structure to humans. “Since most substances that are dangerous in mice are also dangerous in people, it’s likely that those physical problems that cause those mice to have increased deaths also work in people,” says study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives.

Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation’s sugar desire will provide for a truly sweeter future.

1.The study conducted by researchers aimed at learning about________

A. the advantages and disadvantages of sugar

B. the negative effects of sugar on people’s health

C. the genetic structure of mice

D. American’s diet

2.According to the study, which of the following statements is wrong?

A. Sugar can even shorten lives.

B. Sugar’s negative effects are not noticeable.

C. Mice are more likely to diet when fed a diet containing 25% more sugar.

D. Eating much more sugar can make mice put on weight and get high blood pressure.

3.From the passage we can infer_______

A. sugar plays a very important role in Americans’ diet

B. kids consume more sugar than adults in America

C. the study on human beings lasted 58 weeks

D. the genetic structure of mice is totally different from that of people

4.What’s the best title of the passage?

A. Living a sweet life

B. Kids consume much more sugar

C. Genetic structure of humans

D. Danger of sugar

If you’re anything like the average American, you probably check your smartphone more than50 times per day as a 2018 study found. 1. In fact, The University of Arizona found back in2012 that cell phones carry 10 times more bacteria than a toilet seat, largely because toilet seats are typically cleaned more frequently while personal electronics are largely overlooked.

As the novel corona virus (新型冠状病毒) continues to spread, the Centers for Disease Control and Prevention and the World Health Organization are advising the general public to wash hands often and disinfect (消毒) frequently touched objects and surfaces. 2.

But cleaning your phone can be tricky, considering many of the standard cleaning products you’d typically use for disinfection could potentially damage your mobile device. You may want to wipe down your phones screen with some rubbing alcohol or a disinfectant wipe. 3. These phones have a coating on then to prevent oil or grease from your hand from sticking on the phone. Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it. 4.

That lines up with the advice Apple and Samsung offer which warn not to use cleaning products. 5. If you need to disinfect your smartphone, consider looking into a UV light to kill the bacteria.

A.Avoid using alcohol.

B.But in doing so, you risk damaging your devices screen.

C.That means keeping your phone clean is important as well.

D.You should still be cautious when exposing them to liquids.

E.Instead use a micro fiber cloth and dampen it lightly with soap and water.

F.And each time you do, your mobile device picks up more bacteria from your hands.

G.Both companies say wiping your phone down with a soft cloth is the best way to clean it.

Although the United States covers so much land and the land produces far more food than the present population needs, its people are by now almost entirely an urban society. Less than a tenth of the people are engaged in agriculture and forestry(林业), and most of the rest live in or around towns, small and large. Here the traditional picture is changing: every small town may still be very like other small towns, and the typical small town may represent a widely accepted view of the country, but most Americans do not live in small towns any more. Half the population now lives in some thirty metropolitan areas(large cities with their suburbs ) of more than a million people each – a large proportion than in Germany or English, let alone France. The statistics(统计) of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day. As the rush to live out of town continues, rural areas within reach of towns are gradually filled with houses, so that it is hard to say at what moment a piece of country becomes a suburb. But more and more the typical American lives in a metropolitan rather than a small town environment.
