I dreamed of becoming a scientist as a child
What kind of scientist?  I have a degree in Biology with a concentration in Botany.
My dream was in vain I could not become a scientist
Why couldn't you become a scientist?
We are a poor family and I do not have money to study
There are lots of grants and scholarships available.  Have you tried getting some of those?
No. I really like playing in the rain. Do you like it?
I'm sorry.  I don't understand.
