【解析】
15. 考查不定冠词。此处泛指“一个富裕的家庭”，rich以辅音音素开头，故填a。
16. 考查情态动词用法。情态动词couldn't后接动词原形，故填get。
17. 考查名词复数。many different后接可数名词复数，subject的复数为subjects，故填subjects。
18. 考查固定搭配。by oneself表示“独自”，主语为she，故填herself。
19. 考查固定搭配。in simple ways表示“用简单的方法”，是固定搭配，故填in。
20. 考查副词。此处修饰动词believed，需用副词，deep的副词形式为deeply，故填deeply。
