To be fluent in English (英语说得流利)is my dream.I am completely aware that it is difficult 2.to speak English fluently （流利地说英语）.So 1 asked my English teacher for help straight away.She gave me some advice.First of all, it is necessary for you 3.to speak English whenever possible（在任何可能的时候说英语）.Besides, it is very important 4.to practice correct pronunciation （练习正确的发音）.All in all, it is possible for you 5.to be good at oral English （擅 长英语 口 语）if you are hard-working enough.
