假设你是张华，你的悉尼好友Bella最近正因新冠疫情而停课在家隔离。听说无锡在疫情期间开展了停课不停学(Suspended Class, Ongoing Learning)的网络教学模式，她发来邮件询问相关情况。请根据她的邮件进行回复，邮件如下：

Dear Zhang Hua,

How are you doing these days? Recently I have read a lot about the epidemic (疫情) in China on the Internet. Now it seems so serious in Sydney that all students here are asked to stay at home, just as you were months ago. I’m worried about my studies. Is it a good idea to take online courses? What are advantages and disadvantages of online courses? Could you tell me your experience about online courses during your stay-at-home period and offer some advice on how to carry out studies at home?

I hope to hear from you soon. Take care!

Yours,

Bella
