题目
When underline(6) challenges, she kept a positive attitude and approached each obstacle with determination and an optimistic mindset. (confrontation)
When $\underline{6}$ challenges, she kept a positive attitude and approached each obstacle with determination and an optimistic mindset. (confrontation)
题目解答
答案
根据句子结构，“when”后需填入“confronting”以修饰“challenges”，表示“当面对挑战时”。
“Confrontation”为名词，应转化为“confronting”（动名词形式）以符合语法规则。
完整句子为：
"When confronting challenges, she kept a positive attitude and approached each obstacle with determination and an optimistic mindset."
答案：confronting
解析
本题考查非谓语谓语动词中动名词的用法。句子以"When"开头，后接结构需与主语保持逻辑主谓关系。句中主语"she"与动词"confront"（面对）为主动关系，故用动名词"confronting"表"面对挑战时"的状态。原词"confrontation"是名词，需转化为动名词形式符合语法，确保句子结构正确且语义通顺。
