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] Greenpeace appears to be ______ the use of low energy light bulbs.

选项 A、hopeful about
B、irritated with
C、supportive about
D、dissatisfied with

答案 C

解析第3段表明Greenpeace“绿色和平组织”主张提高人们对使用低能耗灯泡的认识，而且认为人们应该知道使用低能耗灯泡对环保有好处，可见Greenpeace是支持使用低能耗灯泡的，因此本题应选C。A是强干扰项，因为hopeful与正确选项中的supportive同为褒义词，但该段并没有涉及现状与将来的对比，也没有对将来做出猜测或期望，所以hopeful无从说起。
