②知道147cm、1m47cm、1。47m，它们之间的联系和区别。
这三个数量表示的多少都是一样的。
只不过单位不一样。147厘米和1。47米只有一个单位。像这样只有一个单位的`名数叫做（）。
1米47厘米有两个单位。像这样有两个获两个以上单位的名数叫（）。在这个复名数中，米是（）。厘米是（）。
③复名数转化成单名数。
（在复名数中，高级单位前面的数不动，只需要把低级单位前面的数除以进率，最后将结果与高级单位数合并。也可以把低级单位的数不动，用高级单位数乘进率，再把结果与低级单位数合并。）
④小数转化成复名数：小数点前是高级数

Dear all,
I am writing this letter to express my gratitude to my parents for teaching me to be positive and to be strong. “Educating the mind without educating the heart is no education at all.” is the opinion held by Aristotle. It is the experience of our forefathers, however, it is correct even today, including my parenting.
It is widely acknowledged that parenting, which can also be explained as family education, is of great significance in our character forming and manner acquiring. To be more detailed, setting good examples instead of just giving precepts is the greatest achievement of my parents. They not only taught me to think for the best and prepare for the worst; they taught me how. They not only told me the benefits of being strong in mind; they proved it. All those things require huge amount of time and work, but it’s worth it.
Without my parents’ contribution and education, I would never be who I am now. But most importantly, I would never be more gratitude to them than today.
Yours,
XXX
