对于一种严重的致死性疾病，评价某种一级预防措施的效果时最恰当的指标是（）。 A.患病

On the terrible day, father took me to school. When he stopped in front of the school, I didn’t want to get out of the car. I looked at the students outside the building and suddenly felt sick. I slowly opened the car door and slowly got out. The body brace(支架) I wore made it hard for me to move and made me feel ugly. How I wished I were still in my school with all my friends. I didn’t know anyone here. I could feel that everyone was looking at me. I was sure that I would be the ugliest and strangest person they had ever seen. Tears fell on my new dress.

I struggled(奋力) to get through that day, and all the day for the following three days. I feel ugly for most of the time. I could hardly wait to take off the brace.

That day finally arrived on a rainy Thursday in Spring. I was so surprised and excited when the doctor said that I could take off the brace. From that day on, I began to love rain. I was free at last.

I danced up the stairs to the school building the next morning. I wanted everyone to see me, but to my surprise, no one said a word about my brace for the whole day, even Danielle, my best friend. I couldn’t wait to ask her, “Danielle, don’t you notice anything different about me? It’s the brace. The brace is gone.”

Danielle just looked at me and said, “ I know the brace is gone, but I don’t think it’ll make much difference. With or without it, you are still my friend.”
