Many women report that the henna crowns really work as a healing device, helping them build a more 20 self-image at a time when they are vulnerable and depressed.
答案：(A) positive
語意「幫助她們建立更『正向』的自我形象」，positive（正向的）符合這種心理療癒的語境；general（一般的）、flexible（有彈性的）、considerate（體貼的）都不合。
四個形容詞修飾 self-image（自我形象）文法上都成立，你可能覺得都說得通而隨手挑一個。這一格要問的是：這些癌症病友當下的處境是什麼，她們需要的是哪一種改變？
同一句的句尾就寫著答案：at a time when they are vulnerable and depressed（在她們脆弱又沮喪的時候）。既然現在是負面狀態，需要建立的當然是正向的自我形象。同句前半 the henna crowns really work as a healing device（指甲花皇冠真的發揮了療癒作用）也是同一個方向；再往前 help women... feel confident and beautiful again（幫助她們重拾自信與美麗），confident 更是 positive 的同義鋪陳。
general（一般的）：自我形象不分「一般」或「特殊」，語意空洞；flexible（有彈性的）用在規則、時間或思考方式上；considerate（體貼的）是形容一個人對別人的態度，不是形容自己對自己的看法。
a positive self-image（正向的自我形象）、self-esteem（自尊）、feel confident（有自信）、work as（發揮……的作用）、a healing device（療癒的工具）、be vulnerable（脆弱的）。
