Pollution is reducing the fragrance（芬芳） of plants and thus preventing bees from pollinating(授粉) them—endangering one of the most essential cycles of nature, a new study suggests.
The potentially hugely significant research, funded by US National Science Foundation, has found that gases mainly formed from the emissions（排放） of cars prevent flowers from attracting bees and other insects to pollinate them. And the scientists who have conducted the study fear that insects’ abilities to drive away enemies and attract mates may also be disturbed.
Professor Jose Fuentes, who led the study, said, “Scent molecules(香味分子) produced by flowers in a less polluted environment could travel for roughly 1,000 to 1,200 meters. But today they may travel only 200 to 300 meters. This makes it increasingly difficult for bees and other insects to locate the flowers.”
The researchers, who worked on the molecules of snapdragons(金鱼草),found that the molecules are volatile(易挥发的) and quickly bond with pollutants, mainly formed from vehicle(车辆)emissions. This chemically changes the molecules so that they no longer smell like flowers. A harmful cycle is therefore set up where insects struggle to get enough food and the plants do not get pollinated enough to multiply.
Already bees, which pollinate most of the world’s crops, are in such a great decline that has never been known before in Britain and across much of the globe. At least a quarter of America’s 2.5 million honey bee colonies have been mysteriously wiped out by colony collapse disorder(CCD),where hives are found suddenly deserted.
The crisis(危机) has now spread to Europe. Politicians insist that CCD has not yet been found in Britain, but considering the present number of bees, the agriculture minister Lord Rooker has sent the warning, “The honey bee population could be wiped out in 10 years.”
Although the researchers are not certain whether this is the real cause of CCD, they say that pollution is making life more difficult for bees and other insects in many ways. In what way does pollution prevent flowers from attracting bees?
| A．By shortening the distance traveled by the scent molecules of flowers. |
| B．By disturbing the bees’ ability to attract mates. |
| C．By weakening the bees’ ability to fight against enemies. |
| D．By stopping flowers from giving off fragrance. |
From the passage we can know that .
| A．Europe is affected greatly by CCD |
| B．CCD has destroyed most of the honey bee colonies in Europe |
| C．no honey bees will be found all over the world in the near future |
| D．European officials have paid much attention to CCD |
What would be the best title for the passage?
| A．Traffic Pollution Puts Bees in Danger |
| B．Traffic Pollution is to Blame for CCD |
| C．Pollution Makes Flowers Lose Their Scent |
| D．Pollution Causes the Decrease in Flowers |
A. The introduction of Paris
B. The culture of Paris
C. The population growth in Paris
D. The production of Paris
E. The education in Paris
F. The industries in ParisParis, the capital and the largest city of the country, is in north central France. The Paris metropolitan area contains nearly 20% of the nation’s population and is the economic, cultural, and political center of France. The French governments have historically favored the city as the site for all decision-making, thus powerfully attracting nearly all of the nation’s activities.
Paris has grown steadily since it was chosen as the national capital in the late 10th century. With the introduction of the Industrial Revolution, a great number of people moved to the city from the country during the 19th century. The migration was especially stimulated by the construction of railroads, which provided easy access to the capital. After World WarⅡ, more and more immigrants arrived.
The city is the centralized control point of most national radio and television broadcasting. It is a place of publication of the most important newspapers and magazines and an international book publishing center. With more than 100 museums, Paris has truly one of the greatest concentrations of art treasures in the world. The Louvre, opened as a museum in 1793, is one of the largest museums in the world.
In the late 1980s about 4. 1 million pupils annually attended about 47, 000 elementary schools. In addition, about 5. 4 million students attended some 11, 200 secondary schools. Approximately 1. 2 million students were enrolled annually at universities and colleges in France in the late 1980s. French centers of learning have served as academic models throughout the world.
Paris is the leading industrial center of France, with about one quarter of the nation’s manufacturing concentrated in the metropolitan area. Industries of consumers’ goods have always been drawn to Paris by the enormous market of the big population, and modern, high technology industries also have become numerous since World WarⅡ. Chief manufactures are machinery, automobiles, chemicals and electrical equipment.
The Cambodian government says more than 378 people died and hundreds more were injured in a stampede(踩踏)during the celebrations of the annual Water Festival late Monday in Phnom Penh. 
Less than 24 hours after the tragedy(悲剧), Cambodia’s most serious loss of life in decades(十年), the government founded an organization to investigate(调查)how so many died on what was meant to be one of the nation’s most joyous occasions.
Most of the victims(牺牲品)were young people in their teens and twenties. They were some of the estimated(估计)two million who had flooded to Phnom Penh for the Water Festival, which marks the end of the rainy season.
Most suffocated on the bridge, which thousands of people were using to leave Diamond Island, an entertainment(娱乐)area in the middle of the river. Others drowned(溺水)after jumping from the bridge into the water.
Buot Panha, 19, said shortly after 9: 30 on Monday evening he ended up trapped(围困)with his friends in the middle of the bridge, fighting to breathe while terrified people struggled all around him.
Being tall saved his life, since he could stretch(伸出)his neck to take in oxygen(氧气). Shorter people were unable to do that, he says, which may be why two-thirds of the victims were women.
He tried to help a woman who was trapped with two children near him. She was screaming for people to help. Being tall, Buot Panha grabbed(抓住)one child and pushed him above the crowd to help him breathe.
But then some of the young men were told to jump off the bridge into the river to make room. So he handed back the child, squirmed his way to the edge, and jumped.
Some like Buot Panha were fortunate, jumping into the river below and swimming for the shore. But many simply could not move, and died where they lay.

Most tourist destinations around China are witnessing travel peaks during the eight-day Mid-Autumn Festival and National Day holidays that run through Sunday. In Beijing, the Palace Museum, or the Forbidden City, attracted 182, 000 tourists on Tuesday, the biggest number on a single day, as millions of visitors arrived in the national capital. “We saw absolutely nothing but people’s heads. ”said Guo Zhijun, 42, of Henan province. “We wanted our 11-year-old son to learn something from the trip, but we only ended up very tired. ”

In the eastern coastal city of Qingdao, its top five major tourist sites attracted more than 200, 000 visitors on Tuesday.
Yesterday, thousands of cars jammed two 20-kilometer mountain roads winding to and out of the Lushan Mountain scenic area in the eastern province of Jiangxi. The area, with about 3, 000 car parking spaces, was unable to contain at least 8, 000 inbound cars, said head of the Lushan Mountain public security bureau.
The Lushan Mountain tourism administration temporarily stopped selling entrance tickets to prevent the traffic from growing on Tuesday afternoon. Similar measures could be taken during the rest of the holidays, a police officer said.
Emergency measures have been taken at other scenic sites. Crowded visitors overwhelmed the capacity(承载量)of the cable cars at Huashan Mountain, in Shaanxi province, leaving tens of thousands of stuck at the peak late into Tuesday night. According to China Central Television, restless visitors demanded refunds from the tourism committee, and a lot of visitors had to give up and walk down the mountain.
Chen Li, deputy director of the Shaanxi Provincial Public Security Department, said on his micro blog that more than 300 policemen and government officials climbed up the mountain to help trapped visitors. Fearing that tourist sites might become too crowded, many people are staying at home, going shopping or making short suburban trips. A resident Mr. Wang in Nanchang, capital of Jiangxi, canceled long-distance travel plans after learning of heavy traffic on many highways during the first two days of the holidays.
