我的梦想是当一名画家：
你心中的梦想是什么呢？是想成为园艺师培养出四季常开的花朵，还是想当一名小朋友喜爱的玩具设计师？是想做一个探险家，去自已任何想去的地方，还是想当一名电影名星？……
我的梦想是什么呢？告诉你们吧：我想当一名画家！
记得5岁那年,妈妈带我去看画展,画展上有淘气的小猴、可爱的小狗……看了这些画得栩栩如生的动物，我就下定心要学会画画，并且长大当一名画家。每次放假做完作业，我就开始画画。我画了一个个戴着帽子的小姐姐回头看，画完后给妈看，妈妈夸奖我画得好，我更爱画画了！
现在，妈妈给我报了绘画班，我太高兴了！昨天，我又答应美术老师参加绘画比赛。我画了一只宠物狗趴在一棵高大的梧桐树下乘凉，我想把这幅画拿去参赛呢！
啊！我爱画画！你们等着吧，我将来还要为四大名著作插图！
