本题为英语语法填空题，需结合句子结构、词性要求、时态语态、固定搭配及上下文语境，填入合适的单词或括号内单词的正确形式。解题时先分析每个空在句中的成分，判断所需词性，再依据语法规则和语境确定最终形式，确保答案符合逻辑与语法要求。
【解析】
11. 空格前有不定冠词a和名词space，结合后文“Dr Yang”可知此处指人，故将名词science转换为表示人的名词scientist（科学家）。
12. 主语为动名词短语“exploring space”，表单数概念，句子为一般现在时，故动词用第三人称单数形式helps。
13. 空格后是名词place，需用形容词性物主代词修饰，it的形容词性物主代词为its。
14. 固定搭配“relationship with...”表示“与……的关系”，此处填介词with。
15. 前文用“First”列举第一点，此处对应第二点，需用序数词Second，首字母大写。
16. 主语“space technologies”与动词use为被动关系，情态动词can后接“be + 过去分词”结构，故填be used。
17. problem为可数名词，此处指多个问题，需用复数形式problems。
18. and连接并列成分，前文为比较级better，故此处用形容词safe的比较级safer，与better对应。
19. 固定搭配“in the far future”表示“在遥远的未来”，需加定冠词the。
20. 前句“听起来疯狂”与后句“地球可能耗尽资源”为转折关系，故用连词but。
21. 时间状语“one day”表将来，句子用一般将来时，故填will build。
22. 空格后是名词journey，需用形容词修饰，meaning的形容词为meaningful（有意义的）。
23. many后接可数名词复数，challenge的复数形式为challenges。
24. every后接单数名词，discover的名词形式为discovery（发现）。
25. 空格处修饰动词explore，需用副词，brave的副词形式为bravely。
