第30题: [简答题]写一短文描述一个地方的变化。内容包括: (1)什么地方; (2)什么变化; (3)自己对变化的感受。 参考答案:
I couldn’t imagine how greatly my little hometown has changed during ten years.
Ten years ago, there was no single brick house. The house we lived in could be merely called hut with only one room and stuffed into three generations mostly. It was really dry outside the houses, no water, no trees, and no harvest.
After ten years, there was no hut any more. Every house we live now has two stories with several rooms and every child has his own room. Wide roads are built with trees on either side, water pipes in houses, and there are two factories in the town.
Big change brings big harvest. Now I walk on the road and feel happy for my little hometown.
