本题为科普类英语完形填空，需结合上下文语境、词汇用法及固定搭配逐一分析选项。解题思路：先通读全文把握主旨（黑洞的发现及意义），再针对每个空格，分析语境所需词义，结合词汇辨析（如“花费”类动词用法）、固定短语搭配，排除不符合语境的选项，选出最佳答案。
【解析】
1. 考查“花费”的固定句型：it takes + 时间 + to do sth为固定结构，主语it指代不定式内容，符合此处“光到达地球需5500万年”的语境，故选B。A项cost主语为物，C项spend、D项pay主语为人，均不符合句型要求。
2. 考查名词词义辨析：根据语境，光从Powehi到地球是一段漫长的旅程，journey（旅程）符合；promise（承诺）、accident（事故）、activity（活动）均不符合，故选A。

4. 考查动词短语辨析：run away from（逃离），句意是太阳无法逃离黑洞的巨大引力，符合；put away（收起）、get into（进入）、get up（起床）均不符合，故选C。
5. 考查固定搭配：neither...nor...（既不...也不...），连接两个并列成分，此处表示光也无法逃离，符合；so（所以）、both（两者都）、either（要么）均不符合搭配，故选D。
6. 考查动词词义辨析：survive（存活），句意是没有生物能在黑洞中存活，符合语境；accept（接受）、spare（抽出）、choose（选择）均不符合，故选A。
7. 考查动词词义辨析：proved（证明），句意是这一惊人发现证明了许多关于黑洞的想法，符合；wanted（想要）、asked（询问）、invited（邀请）均不符合，故选A。
8. 考查动词词义辨析：allow sb to do sth（允许某人做某事），句意是这一发现让人类首次看到黑洞，符合；advised（建议）、avoided（避免）、encouraged（鼓励）均不符合，故选B。
