Last week, when he met with a foreign guest, he was shocked, because not only did he misunderstand what the foreigner said but he couldn’t express himself in English.
Now he has made up his mind to try every means to improve his listening and speaking ability. He will listen to English tape record and English broadcast every day. He will practise speaking English with his friends after class. He hopes to meet with the same foreigner and talk to him freely in English some day.
