课程培训已经结束用英语

不要给你英语老师写这个，他不会喜欢的。 只有中国老师才明白你是在夸奖他。如果是一定要写，也要正面去 说。 比如：The program has finished. Although I can not claim that I've learned a lot during the last three months, at least I started to like English. Thank you!

End one's school time很地道吧:)有时候对中国同胞说的英语表示怀疑~

The six-month long English training course is coming to the end

The English course which keeps three months has been over,I'm not sure how muc I have learned , but at least I am not boring for English.
