问题     This month shops in the UK will begin to phase out traditional tungsten bulbs as part of a government plan to replace them completely by 2011 and save 5m tons of carbon emissions a year. However the current crop of low energy light bulbs are coming under criticism for causing skin complaints and migraines, releasing Mercury into the environment on disposal and not being as energy efficient as new LED equivalents.
    A typical low energy light bulb is said to contain between six and eight miligrammes of mercury. If one is smashed in a home the room should be vacated for at least 15 minutes, the bulb cleared wearing rubber gloves, put in a sealed plastic bag and taken to the local council for disposal. Unbroken bulbs can also be taken back to the retailer if the owner is a member of the Distributor Takeback Scheme.
    Greenpeace has called for a public information campaign to advise people how to dispose of low energy light bulbs safely, arguing that "Rather than being worried about the mercury these light bulbs contain, the general public should be reassured that using them will actually reduce the amount of mercury overall in our atmosphere."
    Further health concerns have come from the bulbs exacerbating of skin conditions in the estimated 100,000 people in the UK with photosensitive skin including suffers of lupus, Xeroderma Pigmentation, eczema and dermatitis.
    There have also been claims that the bulbs cause migraines, affect ME suffers and increase the risk of seizures in people with epilepsy and a growing number of charities including Spectrum and the British Association of Dermatologists are calling for exemptions to allow those affected to continue using traditional bulbs.
    But perhaps the biggest threat to me traditional energy saving light bulb comes from a new type of Light Emitting Diode(LED)developed by Glasgow and Strathclyde Universities.
    LEDs use less power than energy efficient light bulbs currently available but have not historically been powerful enough to be cheaply produced for the mass market. The Scottish scientists have overcome this by decreasing the costs and increasing the speed of Nano-imprint lithography, the process of putting microscopic holes in the LEDs to make them brighter, and suitable for home use.
    Dr. Faiz Rahman, who is leading the project, said: "This means the days of the humble light bulbs could soon be over." [br] The British Association of Dermatologists may acknowledge that the low energy light bulbs

选项 A、are not as effective as traditional light bulbs.
B、produce negative influences on our body.
C、should not be marketed to a large scale.
D、should not be imposed on patients.

答案 B

解析 根据题干中的British Association of Dermatologists定位到第5段。该段中calling for后面的内容表明British Association of Dermatologists认同低能耗灯泡与某些疾病的起因和加重有关,由此可见,B正确。虽然在该段末尾的British Association of Dermatologists表示受到低能耗灯泡影响的病人应该被允许继续传统灯泡,但这不等于他们认为低能耗灯泡不如传统灯泡effective“节能”,可见A是不正确的推断;C、D过于绝对,不正确。
