Health officials issued a waring over common energy-saving l一ghtbulbs(灯泡) after research showed some types could potentially harm the skin and may even raise the risk of cancer.
A study by the Health Protection Agency (HPA) found that some eco-friendly lightbuulbs release levels of ultraviolet (UV) (紫外线) radiation that are above recognized safety limits. The agency urged people who work with lamps nearby to avoid spending more than one hour within a foot of the eco-friendly bulbs. The warning was directed at those using desk lamps for long periods, such as jewellery makers, and others who might have lights close to their faces, such as car mechanics.
John O’Hagan, a scientist at the HPA’s centre for radiation, chemical and environmental dangers, began tests on the ligthbulbs after patient groups raised concern about them. Among the groups were patients with a skin disease called lupus, which makes people highly sensitive to light.
The tests measured UV light from the lamps and found the highest levels of UV radiation, measured 2cm from the lightbulbs, were equivalent to being outside in direct sunlight in the summer. The most immediate risk from the lightbulbs is a reddening of the skin similar to sunburn, but there is also a small increased risk of skin cancer associated with this, again similar to that of sunburn.
The risk of health problems from the lightbulbs was not so high that people should remove them from their homes. People are advised to avoid using open lightbulbs for long close work until the problem is sorted out. It has confirmed that the government will not be reviewing its strategy on introducing energy efficient lightbulbs.

　　There are a lot of dangerous and terrible pests in India, but the tree-bees are the most terrible. They are killers.

　　Last year I was on holiday there. Riding along a road one sunny morning, I found the air above me suddenly became thick with bees. Although it was hot, I went cold all over. To run away fast seemed the only thing to do, but my horse was frightened, too. He jumped and kicked out in all directions to get rid of the bees that were attacking him, and then threw me to the ground.

　　The village was about half a mile away. I began to run. But by now I was covered from head to foot with bees. They crawled（爬行）all over me, stinging （刺）with terrible pain. I tore them away, but made room for others. Each time I opened my lips for breath, more bees entered my mouth. I could hardly breathe.

　　Then I reached the village. I ran towards a house that was being built. As soon as the men working there saw the bees, they ran for safety at top speed.

　　My eyes had completely closed. I fell into a pile of something soft. I pushed myself down into this until my head and shoulders were covered. This made bees angry and they began to attack my legs. I struggled but soon became tired out. The bees had won.

　　At last I was saved by two clever soldiers. They ran to a pile of dry grass and quickly surrounded me with a thick wall of fire and smoke until the bees were driven away. They remained with me, I later learned, looking after me for the next three hours until a doctor was found and brought.
