随堂检测:
Health officials issued a warning over common energy-saving lightbulbs 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 lightbulbs (灯泡) release levels of ultraviolet (UV) (紫外的) 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 lightbulbs 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.
1. Which of the following is true according to the passage
A. All eco-friendly lightbulbs give out levels of UV radiation beyond safety limits.
B. Desk lamp users will suffer skin disease caused by UV radiation.
C. Symptoms of a skin disease led to the start of tests on the lightbulbs by HPA.
D. Patients affected by exposure to UV radiation are highly sensitive to light.
2.. The underlined word “equivalent” in Paragraph 4 most probably means ________.
A. equal B. vital C. relevant D. harmful
3. In order not to be harmed by the UV radiation from some lightbulbs, people should _____.
A. stop using eco-friendly lightbulbs at home
B. avoid using open lightbulbs for long close work
C. take care not to expose their skin to direct sunlight
D. urge the government to ban the use of lightbulbs
4. In the next part, the author would most probably further explain ______.
A. why people needn’t remove the lightbulbs from their homes
B. how researchers have planned to sort out the problem
C. how long people should work close to the open lightbulbs
D. how the government has responded to HPA’s discovery
