Last night a strong wind as well as a heavily rain struck our area. News came that the trees in the park two kilometers away from our school was blown down. This afternoon, they set off the park to do some cleaning. The head of the park met us or gave us some advice on how to clear away the falling trees, branches and leaves. Some times later, we were working hard when it begins to rain. Because few of us had taken along umbrellas or raincoats, so we were all wet. A rain lasted about an hour and it was a pity that they had to stop our work.

【答案】

1.由于其后是名词rain，所以要用形容词来修饰，故将heavily改为heavy.

2.句意：离我们学校两千米的公园内的树被吹倒了，由于主语trees是复数，所以谓语动词也要用复数，故将was改为were.

3.句意：我们出发去公园做一些清扫，set off for...出发去某地，故将set off后加for.
