基础好的同学就直接改写提纲来写私人书信就行了。因为私人书信写作比较任意，模板不好确定。基础不好的同学，就把提纲中规定的东西都写到第二段，一三段按照我写的，模板化。

第一段客套话+写作目的

It is great to hear from you again.

Nothing could have given me greater pleasure than to get news of you.

You have no idea how happy I was to receive your letter.

As to/with reference to /with regard to/as regards … ,引出写作目的

第三段问候语+期待回信
