Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway.

WHO spokesman Daniel Epstein said the microscopic(微小的) ash is potentially dangerous for people when it starts to reach the Earth because inhaled(吸入) particles can enter the lungs and cause respiratory problems. And he also said Europeans who go outside might want to consider wearing a mask.

Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were "hysterical." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder. During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation even in healthy people. But once it falls from a greater distance — like from the cloud currently hovering above Europe — its health effects are often minimal, experts say.

"Not all particles are created equal," said Ken Donaldson, a professor of respiratory toxicology at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be negligible and that only those in the near districts of the Icelandic volcano would likely be at risk.

Dr. Stephen Spiro, a professor of respiratory medicine and deputy chair of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical."

The Olympic Games are seen as the greatest test of an athlete’s ability and are supposed to celebrate the spirit of fair play. But in fact, sportsmen have been using drugs to cheat their way to victory since the Games first began.

       In the early years, athletes ate mushrooms(蘑菇)and plant seeds to improve their performance. Nowadays, this kind of cheating has a name doping(服用兴奋剂).

       Just last month, Britain’s top sprinter(赛跑选手) Dwain Chambers and several American athletes tested positive(呈阳性)for the drug THG. Until a coach secretly gave a sample of THG to scientists, no one knew how ho test for it.

       “We’re like cops(警察)chasing criminals—athletes are always adapting and looking for areas we haven’t investigated,” said Jacquew de Ceaurriz, a French anti-doping expert.

       Since the first drugs test was carried out at the 1968 Olympics in Mexico City, many cheats have been caught out. The most famous case in history is that of Canadian sprinter Ben Johnson.

He broke the 100 meters world record in winning gold at the 1988 Seoul(汉城)Olympics. But days later, he tested positive for drug use, lost his gold medal and was banned from the sport. Five years later, he returned to action—only to be found positive again and banned forever.

China has also had problems with drug cheats. At the 1994 Asian Games, 11 Chinese athletes—seven of them swimmers—tested positive for banned drugs. Sports organizations promised that cheating on this scale would not happen again.

Experts are also worried that doping can damage a person’s health. It is believed to increase the risk of liver and kidney(肝肾)diseases, and women may experience reproductive(生育) problems. As long as they can stay ahead of the scientists, it is unlikely the cheats will stop. But experts say there is a limit to what can be achieved and that athletes will not be able to change their bodies using gene(基因)technology.

“For the moment, genetic doping does not exist,” said de Ceaurriz. “Even in 10 or 15 years it will not be done easily—the scientific community(界)will not let it happen.”

Which of the following is not the way that some athletes cheat to their better sports achievements?

A. Eating mushrooms.    B. Taking drug THG. 

C. Taking genetic doping.   D. Eating plant seeds.

How many countries are mentioned in the passage in which there were athletes doping?

A. Two.                 B. Four.                C. Sic.                  D. Eight.

We can infer from the passage that ____.

A. scientists get a lot of information about drugs before the athletes take doping

B. taking doping will never happen again because of the serious test

C. few athletes used drug cheats before the first drugs test was carried out at the 1968 Olympics

D. problems with drug cheats are still serious though they are severely tested

Which statement of the following is true?

A. Many police are sent to chase criminals of taking doping during the Olympic Games.

B. The drug test was carried out until the 1968 Olympics.

C. There is the possibility that women athletes taking doping will give no birth to a child.

D. Ben Johnson was banned from sports forever for being tested positive for drug use at the 1988 Seoul Olympics.
