二、（2024·辽宁沈阳·模拟预测）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。续写的词数应为150左右。
It was almost New Year’s Eve, and as I made my way home from work, I decided to stop at the
neighborhood coffee shop in our town—a town that had previously been busy and wealthy but was now poor and
deserted. After parking in a parking lot that was close to the coffee shop, I headed toward the shop door when I
spotted trouble.
What lit a warning light in my mind was a group of teenagers—three boys and a girl, each of whom stood on
a skateboard. I wasn’t alarmed by the way they were dressed, which showed they seemed to be a group of bad
teenagers. Rather, it was the extremely late hour and the fact that they wandered on the sidewalk in a half circle
around an elderly man sitting in a chair that raised a red flag in my mind. Wearing only a very worn-out shirt and
without shoes on his feet, the old man looked positively cold and probably homeless.
He was in trouble with a capital T. Against my better judgment, I went inside the warm store and ordered
nice bread and a cup of coffee while keeping a worried eye on the group outside. Thoughts raced through my mind,
and I was wondering what the intentions of these teenagers were. “What do the teenagers want on earth? Do they
intend to play a bad trick on the old man, make fun of him, or…?” I wondered, anxious. “Whatever it is, they seem
to plan to do something bad to him. Oh, these kids seem to be mean,” I thought and felt upset.
But nothing seemed to be happening. Slightly relieved, I began to enjoy my food. However, minutes after I
finished my food and headed toward my car, something indeed was “going down”. I heard one boy say, “Stand up
and walk.” “Oh, no,” I thought. “The old man is now in real trouble.”
注意：

But wait, I had misjudged the situation.
