手足口病诊断标准

根据短文内容选择最佳答案。

One day when I was 9 years old, I was lost when I went shopping with my parents.

I walked and looked for my parents. I did not know what to do. When I wanted to cry, I remembered my father’s words that I was now "a big girl" and then I walked bravely (勇敢地).

I went to the bookstore on the first floor. My father wanted to get some books just now, but my parents were not there. Then, I went to the shoe shop on the second floor. My mother went to buy a pair of shoes. I did not find them there. "Did they go home? How could I get home then? "I was very worried (焦虑的).

Then an idea came up. I ran to the Information Counter (信息台). I told the clerk that I was lost. The news went out over the loud speakers of the shopping center.

My parents arrived at the counter later. They looked worried, too, but I was happy for finding them.
