范文
who i am
    i'm a very common girl．i'm not beautiful．nobody cares about me．i often feel lonely．i'm very weak in health．i often catch cold．i'm an unhappy girl．
    i do badly in study．i often fail in the examination．i like crying．i'm always very sad．i always hope to get it but i never know how to get it．i'm like a bird．i only want to fly away．but i don't know where my home is．i don't know what i should do．
    however，i'm very lucky this year．a kind teacher comes into my life．she teaches me many things．little by little，i become happier．i think 1 will know who i am soon．
