My hometown has changed a lot. It used to take nearly forty minutes to go to school on rough roads. Twenty years ago, there were only narrow dirt tracks around our village. Now the government has built many wide highways, and it only takes fifteen minutes to get to town. There used to be lots of sandstorms on the hills, but we have planted thousands of trees these years. I am really happy to see such beautiful changes around us.
解析：包含used to句型、一般过去时(twenty years ago)、现在完成时(has built / have planted)三类目标语法。
短文2
Great changes have taken place in villagers’ daily life. People used to travel far to see doctors and shop in the past. They grew small vegetables on tiny farms ten years ago. Now the village has built new hospitals and big supermarkets, and many farmers have set up high-tech greenhouses. Lots of young people have returned to start their own business instead of working in faraway cities. Every day we can feel how much better our life becomes.
