[单选题]AChristopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes(糖尿病), Thomas would need to inject himself with insulin(胰岛素) three times a day for the rest of his life or risk nerve damage, blindness, and even death. And if that weren't bad enough, he had no health insurance.

He has a positive attitude to this disease.

解析：

细节理解题。通读全文可知，Christopher Thomas对于自己的疾病采取了积极的态度，所以C项正确。A项与Thomas would need to inject himself with insulin(胰岛素) three times a day for the rest of his life不符；B项与文中的Thomas开办网站，与病人及其家属分享有关的信息和资源不符；D项提到的写作是Thomas的专职工作，而他的志愿工作才是运作Fight It 这个慈善机构。

[多选题]（乙）实用类文本阅读阅读下面的问题，完成13-15题。

要求医生“上知天文下知地理，中知人事”可视为《内经》“天人合一”理论在诊治疾病时的具体运用。

《内经》认为诊断“人”的病，不仅要关注“人”的生理状况、心理因素．还要考察“人”生活的社会、自然环境。

解析：解析：本题考查了考生对文本内容的理解和把握。A项理解过于绝对与僵化，这一点在文章第二段可以印证。C项对“人事”的解释和原文第四段相对照可以看出太狭隘，不全面。E项的内容纯属无中生有，原文没有这个意思。
