B.decreased

C.changed

D.disappeared

正确答案:

A

答案解析:

本句后半部分说到，由于艾滋病的传播和抗药型结核病的出现，那么根据推理，结核病自然应该“增加”，而不可能“减少”或“消失”。

至于“变化”，不应该是结核病本身发生变化，而应该是发病率发生变化。

C.onethousandstars

D.morethan14,000stars

本题难度不大，答案依据比较明显，在文章第一段第二句，这句话主要谈到，在晴朗的夜晚人们能看到14，000多颗星星，回来看选项，D项符合原文句意，是答案。

本题有一定难度，考查whatpoint的用法，干扰项有一定的干扰。

whatpoint，固定搭配，指“什么意义”，可引导问句，文章此处是说“科学家说如果天花真的在这个星球上消失了，保留这些储备病毒的还有什么意义？

”答案是D。
