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 welcomed 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 welcomed by leading charities(慈善) , caution has also been voiced over the length of time it will take before a portable lung will become 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.
1.Which of the following about the portable lung would the author agree?
A. It can help a lot in lung transplants
B. It was once on display
C. It works differently from the normal one in the body
D. It’s just like an oxygen bottle.
2.It seems as if _______ really matters before the portable lung is put into use.
A. support B. money C. time D. trial
3.What’s the author’s attitude towards the portable lung ?
A. Negative. B. Doubtful. C. Curious. D. Objective.
4.Which edition can you probably find the passage ?
A. Science. B. Culture. C. Economy. D. Education.

查看习题详情和答案>>There was once a man who had a donkey and a beautiful lapdog. The donkey was kept in a barn and had plenty of corn and hay to eat. Indeed, he was just as lucky as any donkey could be. The little dog stayed in the house and was well liked by the master. He was always playing and jumping about in an funny way and was allowed to lie in his master’s lap(膝盖). Meanwhile, the donkey had plenty to do. He pulled wood all day long and had to take his turn at the mill during the night. He often complained about his problems, and it bored him to see the lapdog living such an easy life, while he had to work so hard. Finally he thought to himself that if he acted the same way as the lapdog to his master, he would be treated the same way. So, one day he ran out of his barn and went fast into the house, where he began to kick about in a very strange way. Then, swaying his tail and imitating the funny behavior of the pet lapdog, he knocked over the table where his master was eating. He also broke all the dishes into very small pieces and did not stop until he jumped onto his master, trying to lick and paw him with his rough feet.
Seeing their master in great danger, the servants thought it was time to help him. They beat the foolish donkey with sticks until he could not get up again. As he was about to die, he cried, “Why couldn’t I have remained satisfied the way I was? Why did I try to imitate a creature who was nothing but a lazy puppy after all?”
