Last year,I did not like my English class. Every class was like a bad dream. The teacher spoke too quickly. But I was afraid to ask questions because my pronunciation was very bad. So I just hid behind my textbook and never said anything.Then one day I watched an English movie called Toy Story.I fell in love with this exciting and funny movie! So then I began to watch other English movies as well. Although I could not understand everything the characters said, their body language and the expressions on their faces helped me to get the meaning. I also realized I could get the meaning by listening for just the key words. My pronunciation also improved by listening to the interesting conversations in English movies. I discovered that listening to something you are interested in is the secret to language learning. I also learned useful sentences like "It's a piece of cake "or" It serves you right."I didn't understand these sentences at first. But because I wanted to understand the story, I looked up the words in a dictionary.Now I really enjoy my English class. I want to learn new words and more grammar. Then I can have a better understanding of English movies.
