Dear friends,
Do you remember your first day at a new school or in a new area? How about the1when your family2 to a new state? Ugh! What about the feelings of being a stranger?
Then, with time, you find someone who likes 3you like.  Friends are great gifts in life. I have good friends too,  but not because they are completely(完全的)4 .Sometimes they talk too much; sometimes they need me a lot. I know I ask too much of them. I hope my friends, like my father,5about me a lot.
I once told my friends to give me all their love and be generous and gentle. I told my friends, in other words, to love me6I loved them.
They didn’t7 me at first, but then they became kinder. My love for them slowly made them learn to8 friends. They learned to love others and 9the idea that LOVE is part of life.
If we listen to and try to understand each other, love10.We should work on it, even if it’s hard at first. A true friend loves US at all times.
Your friend,

“修身齐家治国平天下”是中华传统文化的一个重要理念。 2016年 1月 12日，******在中央纪律全会上强调，加强社会道德建设必须加强执政党广大干部和党员的家风建设，党的领导干部必须把家风建设摆在重要位置，廉洁修身、廉洁齐家。传统的家规、家风、家训作为一种民间教化的工具，在今天依然发挥着它们独特的作用：《钱氏家训》以儒家“修身齐家治国平天下”理念为框架并加以发展，使钱氏家族人才辈出，如号称“科技三钱”的钱学森、钱伟长和钱三强。 “梁启超一生，唯一不变的是爱国”，梁启超的家规集中一点就是“爱国”，在这种家规的教育下，梁启超的九个子女，个个成才，报效祖国。

结合材料，运用“探究世界的本质、把握思维的奥妙”的相关知识，说明我们为什么要发挥家规、家风、家训在社会道德建设中的作用。
