Answer 1

【答案】

【1】F

【2】C

【3】G

【4】E

【5】A

【解析】

试题分析：在本文详细描述了哈尔滨PM2.5超标，说明了空气污染对于人类健康的影响，特别会导致一些诸如肺癌，膀胱癌的发生。目的在于提高人们对于环境保护的意识。

【1】F 根据前一句.....reached levels of 1,000 micrograms per cubic meter可知哈尔滨的PM2.5的含量达到了每立方米1000，这是非常非常高的数据，为了强调PM2.5的浓度很高很危险。F项“40 times the safety level reminded by the World Health Organization.”这是国家标准的40倍，恰好在强调这种情况。故F项符合上下文串联。

【2】C 根据横线后一句It stated that there is “ sufficient evidence” that exposure to outdoor air pollution causes lung cancer.有明确证据说明接触户外空前污染会导致肺癌。这与C项“Just days previously, the WHO classified air pollution as a carcinogen（致癌物）.”说法相一致。

【3】G 横线前面一句It stated that there is “ sufficient evidence” that exposure to outdoor air pollution causes lung cancer.可知接触到空气污染会导致癌症，且C项说明世界卫生组织宣布空气污染与癌症有关，所以横线句仍然是这一说法的论据，故G项“And meanwhile, the risk of bladder（膀胱）cancer is also closely connected with it.”与横线前一句都在证明本文第一句。

【4】E 根据横线前一句On the Chinese social media site Weibo, many users complained about the pollution and shared their concerns.可知在微博上很多人都在抱怨空气污染并表示担心。横线句内容应该是人们的抱怨，E项“References to “feed people with smog” have become popular on Weibo.”这是这种说法。

【5】A 根据横线后一句There won’t be a sudden outbreak of symptoms空气污染带来的症状是不会一下子就爆发出来的，有一个渐进的过程，所以A项“The impact of air pollution on people will be gradual.”与之相一致。
