帮忙把这篇英语作文的语法点全部找出来
Last summer I spent a two-week vacation at my aunt's place.My aunt lived alone in a mountain village,with a small river winding its course everyday.
　　One morning I went fishing in the river,where two women washed clothes.I fimnd a most favorable point.Casting out my line I waited anxiously for a bite.Suddenly there came a cry:"Help!Help!" I looked in the direction of the call and saw a boy falling into the river.Throwing the fishing pole,I dashed over like an arrow,jumped into the river and swam very quickly towards the boy.Then together with his mother I carried the boy on my back to a nearby hospital.That boy was saved.The mother gave me a thousand thanks.
　　Back to my fishing place,I fimnd my fishing pole floating on the water.I managed to get it.But to my great surprise,there was a big fish on the hook.
