SECOND LANGUAGE
ACQUISITION
by
Alejandra Corvalán Bravo

2. Introduction
I always feel nervous when speaking English.
I feel bad in my mind because I wonder why I can’t speak English
very well.
I never learned the preposition; I cannot learn this bloody language
.
My English is not good enough; I can’t express myself very well.
I need to use English perfectly; I can’t make mistakes in front of my
classmates.
Sometimes I feel stupid, some people look at me, a strange man
speaking English?
