67. 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
Anna was always known as the quiet girl. Despite her love for painting, she never shared her works with anyone. In her final year of high school, she came across a poster announcing an art competition. The theme of the competition was “Courage”, and the prize was a scholarship to a well-known art school. It was the opportunity Anna had dreamed of, but her fear of judgment held her back.
For days, Anna struggled with self-doubt. Her best friend Mia tried to encourage her. “You have a gift, Anna. Don’t hide it,” she said. But Anna could only think of all the ways she might fail. Her paintings, filled with vivid colors and bold strokes (笔触), were a reflection of her personal emotions, and the thought of others seeing them made her feel exposed and lacking in confidence.
One evening, while considering whether to enter the competition, she received a call from her older brother Tom, who was studying abroad. “Remember Dad’s old easel (画架) ” he asked. “He always said it was meant for an artist who isn’t afraid to show the world who they really are.”

17.答案：（1）D
（2）B
（3）酸；
18.答案：（1）46.7%；铵态氮肥
（2）；碳酸氢铵溶于水流失造成的
解析：（1）尿素[]中氮元素的质量分数为；尿素中的氮元素需要转化成铵态氮肥才能被植物直接吸收。
（2）造成铵态氮肥（）肥效降低的原因一是该化肥易分解生成和两种氧化物，根据质量守恒定律，反应前后元素种类不变，则这两种氧化物为二氧化碳和水，该反应的化学方程式为；二是雨水导致，结合题图和碳酸氨铵易溶于水分析，可能是碳酸氢铵溶于水流失造成的。
