  Last year my English class was     1      for me. First of all, it wasn’t easy
for me to understand the teacher when she      2      to the class. To begin with,
she spoke too quickly, and I couldn’t      3       every word. Later on, I realized it
doesn’t matter if you don’t understand every word,     4      I was afraid to speak
in class because I thought my classmates might laugh   5        me. I couldn’t
always make complete sentences, either. Then I started to     6     
English-language TV.It helped a lot. I think that doing lots of listening practice is
one of the secrets of  7        a good language learner. Another thing that I found
very difficult was English      8     . So I decided to take lots of grammar notes in
every class.
