最近，受新冠肺炎疫情影响，李华的美国朋友David要在家里上网课。David得知李华上过网课且成绩优秀，于是写邮件祝贺并求助。假定你是李华，请就David的邮件作回复。

Data:28 March  From: David  To: LiHua  Subject: Asking for advice

Dear Li Hua

    Congratulations on your excellent academic performance in your exams of online courses! Paced with the COVD-19 pandemic, we now have to take online classes just as you did not long ago. So I am writing to ask you for the recipe for effective independent learning as well as the approach to avoiding a lonely life at home.

    I'd like to know how you are able to ensure full-concentration while having online classes. Besides, owing to the terrible virus getting-togethers have already been called off. There is no exception to our weekly Chinese cultural activities. You are welcome to recommend some activities for me to take up alone.

    I am looking forward to receiving your reply.

Love

David
