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."

(1) What is the single largest cause of sick leave in the UK? The answer is not the common cold or flu, but back pain. Back pain affects one in three British adults, costs the country over £5 billion every year and is extremely difficult to treat.

(2)But now Britain's National Health Service (NHS) will be offering a new solution: acupuncture (针灸).The ancient Chinese needle treatment has been around in the UK for many  years, but this is the first time it has been officially supported.

(3)Traditionally, doctors in the UK have advised back pain sufferers to stay active, do stretching exercises and take painkillers when necessary. In more serious cases some people are given X-ray treatment or injections.

(4)The National Institute for Clinical Excellence (NICE), however, say there is evidence that acupuncture may_____ than expensive X-rays or injections, so patients who have been suffering for over six weeks should be given a choice. As an alternative to acupuncture, patients will be able to opt for either a course of spinal manipulation (脊椎推拿), or a series of special exercise sessions.

(5)In the UK, acupuncture is classed as a complementary treatment, which is the term given to a medical procedure which hasn't gone through the strict trials by which scientists prove some treatments work.

(6)While many experts have welcomed the move to make acupuncture available on the NHS, some are still sceptical about its effectiveness. Research from the US earlier this month found that simulated acupuncture using toothpicks which do not make a hole in the skin could be as good as using real needles. So while some are yet to be convinced, back pain sufferers will be hoping that acupuncture helps get them feeling healthy and mobile again. Employers, on the other hand, will be hoping it gets them back to work.

1.What's the best title of the text?(No more than 10 words)

2.Complete the following statement with proper words.(no more than 3 words)

Not all experts are convinced of the benefit of acupuncture although many of them have ______for the application of the treatment

3.Fill in the blank in Paragraph 3 with proper words。(no more than 5 words)

4.What’s the difference between simulated acupuncture using tooth picks and real acupuncture?

Computer people talk a lot about the need for other people to become “computer-literate.” But not all experts (专家) agree that this is a good idea.

One pioneer, in particular, who disagrees is David Tebbutt, the founder of Computertown UK. Although many people see this as a successful attempt to bring people closer to the computer. David does not see it that way. He says that Computertown UK was formed for just the opposite reason, to bring computers to people and make them “people-literate.” David Tebbutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two. The clubs are for people who have some computer knowledge already. This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage them and answer any questions they have. They are not told what to do, they find out.The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask. People don’t have to learn computer terms(术语), but the experts have to explain in plain language. The computers are becoming “people-literate.”

1.Which of the following is David Tebbutt’s ides on the relationship between people and computers?

A.Computer learning should be made easier.

B.There should be more computer clubs for experts.

C.People should work harder to master computer use.

D.Computers should be made cheaper so that people can afford them.

2.We can infer from the text that “computer-lilerate” means_______.

A.being able to afford a computer

B.being able to write computer programs

C.working with the computer and finding out its value

D.understanding the computer and knowing how to use it

A.help to set up more computer clubs

B.bring people to learn to use computers

C.bring more experts to work together

D.help to sell computers to the public

4.David Tebbutt started Computertown UK with the purpose of______.
