A portable lung which could help those with breathing problems lead a normal life is being developed by scientists.
The Swansea University scientists say it could take many years before the device(装置) , the size of a spectacle box (眼镜盒) , is available . Lung patients , who have seen how it would work , have weled the research.
Its research suggests that one person in every seven in the UK is affected by lung disease---- this equates to approximately 8 million people. As of 6 March 2009, 217 people were on the waiting list for a lung transplant（移植） according to figures by NHS Blood and Transplant .
Now scientists in Swansea are developing a portable artificial lung which could transform (改观) the lives of patients . Researchers claim that in the long term the device could offer an alternative to lung transplant , giving hope to those who suffer from conditions such as emphysema(肺气肿) and cystic fibrosis.
The device mimics the function of a lung---by getting oxygen into and carbon dioxide out of the blood stream . Professor Bill Johns came up with the idea after his son died of Cystic Fibrosis . It is important that we make something that will help people , who instead of being confined (局限) to a wheelchair with an oxygen bottle , can actually walk around and do things for themselves , he said.
Although the research has been weled by leading charities(慈善) , caution has also been voiced over the length of time it will take before a portable lung will bee available .
“We have to stress that this is several years away from being used , even in a trial stage,” said Chris Mulholland , head of the British Lung Foundation.
Patient Elizabeth Spence from Swansea has been refused the double lung transplant she needs but remains hopeful that one day the new device could save her . “ My body will reject the lungs , so this possibly could be an answer--- another way of getting new lungs without actually having the transplant,” she said.

(答案→)B
解析：文章介绍了一种新发明——便携式肺器官。这是一种只有眼镜盒大小的装置，可以模仿人体肺部功能把氧气输入血液，同时把二氧化碳排除人体血液系统。这给肺病患者带来了很大希望，但是专家称此装置还需要很长一段时间才能投入使用。
【小题1】B推理判断题。从文章第二段Lung patients , who have seen how it would work , have weled the research .可知肺部患者见过这种装置的运作过程，由此推断这种发明曾经展示过，故B选项正确。
【小题2】C细节理解题。从文章倒数第二段“We have to stress that this is several years away from being used , even in a trial stage,”可知即使是试验阶段也得需要几年的时间才能被使用。
【小题3】D推理判断题。A消极的；B怀疑的；C好奇的；D客观的。从文章的整体内容可知，作者只是介绍这种装置，引用或转述别人的话，而没有加入个人的观点看法，由此可知D选项正确。
【小题4】A推理判断题。文章内容是关于一种新型医疗装置，并且文章开头提出。。。is being developed by scientists，由此判断文章是选自科学版面。故A选项正确。
