There is a lot to learn about the creations of Beatrix Potter¡ªnot only is she the author and illustrator of one of the world's most famous children's books,The Tale of Peter Rabbit,but also a pioneering conservationist with the spirit of a scientist.

"Potter grew up as the daughter of a wealthy Victorian family,but along with her brother who filled an entire floor of their large house in London with all sorts of animals,"said Anne Lundin,a retired professor for the UW-Madison School of Library and Information Studies.

"As an adult,she was a frustrated botanical illustrator and scientist.That field was not open to her because she was female,"Lundin said.Potter was urged to tum the charming illustrations and stories she wrote in letters to children into books.She wrote 23 books in all¡ªa body of work that has inspired plays,ballets,films and an astonishing amount of merchandise.

"The Tale of Peter Rabbit is probably the most famous children's book in the world,which was published in 1902 and has really stood the test of time.It's been translated into 36 languages.The parents and grandparents will share it with the next generation,"said Lundin.

Potter also made a mark on the world through her land conservation."In many ways,she was like Peter Rabbit, venturing into a world of adventure and risk.She withdrew from London as soon as she started making some money on her books to the Lake District and became an extremely important farmer and conservationist.She preserved and passed on 15 farms and over 4,000 acres,which were given back to the country as gifts in the 20th century,"said Lundin.

Even though she was born 150 years ago,she was amazingly modern¡ªher embracing of the natural world, commented Jennifer Blatchley Smith,an artistic director of the show Peter Rabbit Tales to celebrate the 150th anniversary of Potter's birth.

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(ËÀÍöÂÊ) 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(²ñÓÍ»ú) 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.

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

Everyone has got two personalities¡ªthe one that is shown to the world and the other that is secret and real.
