解题思路：先明确方框内单词/短语的含义及用法（thick：厚的；brave：勇敢的；however：然而；belt：腰带；make progress：取得进步），再结合每个空的语境、语法规则，选择合适的词，判断是否需要变形（本题无需变形，直接使用对应形式）。

52. 固定搭配safety belt意为“安全腰带”，结合语境教练提供的安全装备，故填belt；
53. 前文提到想放弃，后文说决定坚持，是转折关系，且位于句首，需用however（然而），首字母大写，故填However；
54. 结合语境“慢慢我取得了进步”，描述过去发生的动作，用make progress的过去式made progress，故填made progress；
55. 形容词作表语，结合“足够勇敢面对困难”，需用brave，故填brave。
