It seems individual cancer cells send out the same distress signals as wounds, tricking immune cells into helping them grow into tumours. The finding suggests that anti-inflammatory drugs could help to combat or prevent cancer. "Lifelong, if you take a small quantity of something that【C1】______ inflammation (炎症), such as aspirin, it could reduce the risk of cancer," says Adam Hurlstone of the University of Manchester, UK.
When tissue is wounded or infected it produces hydrogen peroxide. White blood cells called leukocytes (白细胞) are among the first cells to react to this【C2】______ , homing in to kill the infectious agent, clean up the mess and rebuild【C3】______ tissue. At first, the tissue becomes inflamed, but this subsides as the wound is cleared and rebuilding continues. Now, a study in zebra fish shows that this process is also instigated (唆使) and sustained by tumour cells.
Hurlstone and his colleagues【C4】______ engineered zebra fish so that skin cells and leukocytes would show different【C5】______ under ultraviolet light. Some zebra fish were also engineered to have cancerous skin cells.
The team found that the cancerous skin cells secreted (分泌) hydrogen peroxide,【C6】______ leukocytes which helped them on their way to become a tumour. When the team【C7】______ hydrogen peroxide production in the zebra fish, the leukocytes were no longer attracted to cancerous cells and the cancer colonies reduced in【C8】______.
More alarmingly, the researchers found that healthy skin cells【C9】______ to the cancerous ones also produced hydrogen peroxide, suggesting that cancer cells【C10】______ co-opt them into triggering inflammation.

选项
答案
E
解析
形容词辨析题。由空格前的动词rebuild和空格后的名词tissue可知,此处需要填入形容词作名词的定语。根据句子大意:白细胞首先产生反应,自动导引到伤口消灭感染源,清除伤口污物,并重新修复_____组织,再结合所给选项,可以推断出,应是修复受损伤的组织。hurtful“伤害人的”不符合句意, damaged“受损伤的,被破坏的”正确。
