Tiny pieces of gold could be used in the fight against cancer, new research has suggested. Scientists at Edinburgh University have just completed a study which shows the【C1】______metal increased the effectiveness of drugs used to treat lung cancer cells. Minute fragments, known as gold nanoparticles(纳米粒子), were【C2】______in a chemical device by the research team.
While this has not yet been tested on humans, it is hoped such a device could one day be used to reduce side effects of current chemotherapy treatments by【C3】______targeting diseased cells without damaging healthy tissue. Gold is a safe chemical element and has the ability to【C4】______chemical reactions.
Researchers at the University of Edinburgh discovered properties of the metal that allow these catalytic abilities to be accessed in living things without any side effects. The device was shown to be effective after being【C5】______in the brain of a zebrafish, suggesting it can be used in living animals.
The study was carried out in【C6】______with researchers at the University of Zaragoza’s Institute of Nanoscience of Aragon in Spain, with funding coming from Cancer Research UK(CRUK). Dr. Asier, from the University of Edinburgh’s CRUK Edinburgh Centre, said: "We have discovered new【C7】______of gold that were previously unknown and our findings suggest that the metal could be used to【C8】______drugs inside tumours very safely. There is still work to do before we can use this on【C9】______, but this study is a step forward. We hope that a similar device in humans could one day be implanted by surgeons to activate chemotherapy directly in tumours and reduce harmful effects to healthy organs. " The next steps will be to see if this method is【C10】______to use in people, what its long- and short-term side effects are, and if it’s a better way to treat some cancers.
A)accelerate I)precisely
B)cautiously J)previous
C)collaboration K)properties
D)elaboration L)release
E)encased M)relieve
F)implanted N)safe
G)patients O)unsafe
H)precious [br] 【C4】
选项
答案
A
解析
空格前是动词不定式标志词to,故此处应填入动词原形。文章第二句提到金子能提高药效,结合上下文语义,此处指黄金能“加速化学反应”,以促进药品发挥效力,故答案为A)accelerate“加速”。
