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
【C2】
选项
答案
E
解析
空格所在句主语为fragments,空格位于were之后,句末有动作发出者the research team,故此处应填入动词的过去分词,与were构成被动语态。结合原文,此处指纳米粒子被包裹在化学仪器里,be encased in为固定搭配,意为“包裹于……”,故E)为答案。
