Dear Madam,
Hello,how are you and Jim doing recently?I've been taking up English lessons lately and I realized that those lessons really help to improve my English standards.The teachers are all very dedicated and approachable,one of them even offered to help tutor me as I was really lacking behind in my foundation.The lesson materials are also very interesting and aids in memorization!I now can remember many more vocabulary words and understand all those complicated rules of grammar.I strongly recommend Jim to take up the lessons with me!I'm eagerly awaiting your reply!
Best regards,
Liming太给力了，你的回答完美解决了我的问题！
