V.短文改错(共10小题,每小题1分,满分10分)

I used to going into the countryside to draw animals and plants, one day I

was walking across a field, looking for rabbits to draw. Lost on thought, I hadn't

noticed a bull (公牛) to running towards me. About 100 metres ahead were a

tree under which I would sit and draw. Suddenly, I heard the noise behind me. I

turned and saw the bull. I knew a bull can run more faster than a man, and I also

knew that a bull can't see very clear and notice only shape and movement.

So I ran calmly towards the tree, keep the tree, myself and the bull in a

straight line. I also threw my bag to the right, so it was out the line of the  tree. The bull saw a sudden movement and headed to the bag. I reached the tree and climbed up it.
