假设你是新华中学的学生李华，你原来的外籍教师Professor Johnson已经回到了英国。请你用英语给他写一封电子邮件，包括以下内容：
1）. 感谢他对你的帮助；
2）. 介绍你最近的学习和生活；
3）. 邀请他和家人来中国过春节(the Spring Festival)
注意：
1）. 词数100字左右；
2）. 可以适当增加细节，以使行文连贯。
Dear Johnson,
How is it going? It has been nearly a month since you returned to your country.
I recall the days you taught us. You are such an energetic and humorous teacher that we like your lesson. I am grateful for your help in my spok
