Read the text carefully

My name is Linh. I’m a pupil at Kim Dong Primary School. I’m in class 5A with Lee and John. I love reading comic books. I often read them in my free time. When I see a new word, I try to guess its meaning. I write the word in my notebook and say it many times. I often stick new words on my bedroom walls and practise reading them aloud. Lee and John love learning English too. We often learn to speak English by talking with our foreign friends in our free time. Lee is very good at English. She usually practises listening by watching cartoons on TV. She learns to write my writing emails to her friends every day. John loves reading. He goes to the library twice or three times a week. He usually read English books to practise reading. They always help me to learn English. We are happy because we can understand each other. English is necessary for communication.
