I think I am smart
I think I'm smart,this opinion I'm keeping since I was young.
In my primary school-time,our classmates always play more funny with me,because I usually had some special ideas.I was naughty when young.But in class,I was a good student.Many questions teachers asked,no one but me could answered.So I thought I'm smart at that time.
As time goes,now I have become a collage student,my childishness has fade away.I know I just was a little clever ago,not intelligence.
To be a intelligent man,I study hard,not only in class,but also by reading books about history,politics and psychology and so on.Though these methods,Ihave made some improvement.
I think I'm smart,but not just a thinking,I'll be!

I believe that I'm a smart since I was a little boy,I
earn talent in many different fields.
when I was in primary school,no doubt,I was the best
student.Children in the same age often surrounded me
result in I had so many special ideas which were full of
imagination,what's more,in the class ,I was my
teacher's favourite,when the problem which no one else
could answer came to me ,it became easy!
As time went on,I become more and more mature.I wake
up to the truth that there is no intelligence on me.I
must work hard to be a intelligent man!
fortunately,though the years of study both in class and
out of class,everyday's reading books about
history,politics,and psychology,I have made some
improvement!
It's not a dream that I'm smart,I will make it
