雅思G类小作文书信写作开头写法
1.正式和半正式的G类书信作文开头写法。尽量开门见山直奔主题，不用刻意寒暄，直接道明写信原因即可，因为你不知道你不知道你在给谁写信。
Formal:
Dear Sir/Madam,
I am writing to inquire about…
I am writing in connection with…
Semi-formal：
Dear Mr Johnson,
I am writing to inform you that…
I am writing to…
2. 非正式的G类书信作文开头写法。在表达写信目的之前，先展示你们的友谊，第一段可以友好的闲聊寒暄，与你写作的原因无关。如：
Dear Susan
I hope you and your family are all well! It was so wonderful to spend time with all of you last month. It felt great to catch up with you and Bob, get to know your children, and have fun together after so long. You have always been dear friends of mine, and always will be.
Anyway, the reason I’m writing is that I have some good news: I am getting married in September…
前面一段都是叙叙旧，第二段才切入主题：原来是要结婚邀请信……
