某本杂志是月刊，每月发行一期。最新的一期是第72期。这本杂志创刊多少年了？

请建立如下的表格，计算D列的“总计”，其数据表保存在sheet 1工作表中。

	A	B	C	D
1	某厂各车间1月份生产情况
2	车间	数量	价格(元)	总计
3	1	4	12000
4	2	5	9000
5	3	6	8500
6	4	12	6500

2．对建立的数据表选择“车间”和“总计”数据建立“三维簇状柱形图”，图表标题为“粮食产量图”，并将其嵌入到工作表的A9:F20区域中。将工作表sheet1更名为“1月份生产表”，保存到EX20.XLS。

My son starts school today. It's going to be   1  and new to him for a while. And I wish you would sort of treat him    2   .      You see,    3   , he's been king of his own room. He's been    4   of the back yard. I have always been around to   5   his wounds, and to comfort his feelings.      But now-things are going to be   6   .      This morning, he is going to walk down the front steps, wave his hand and start on his great  7   that will probably include wars and tragedy and sorrow. To live his life in the world he has to live in   8   faith and love and courage.         9  , World, I   10   you would sort of take him by his young hand and teach him that things he will have to know. Teach him- but gently, if you can. Teach him that for every scoundrel there is a hero; that for every dishonest politician, there is a   11  leader; that for every enemy there is a friend. Teach him the wonders of   12  .      Give him quiet time to   13  the mystery of birds in the sky, bees in the sun, and flowers on the green hills. Teach him it is far more honorable to fail than to   14   .      Teach him to  15    his own ideas,   16   everyone else tells him they are wrong. Teach him to sell his strength and brains to the highest bidder, but never to put a price on his   17  . Teach him to close his ears to a howling mob(暴徒)... and to stand and   18    if he thinks he's right. Teach him gently, World, but don't   19   him, because only the   20   of fire makes fine steel.      This is a big order, World, but see what you can do. He is such a nice little fellow.

通过对南非考古遗址中的蛋壳碎片的氨基酸的分解进行分析，可以得知20万年以上的遗址的确切年代。因为氨基酸的分解在寒冷的地区较慢，所以在一些寒冷的地区，这种技术可用于鉴别在100万年左右的考古遗址。
如果上述断定是真的，那么以下哪项最有可能是真的？（）

A.最古老的遗址不是在南非，而在其他寒冷的地区。

B.蛋壳中可被测量的氨基酸分解不会出现在其他的一些遗迹上。

C.如果遗址所在地的气候在被测量的年限范围内有大幅度的波动，那么这种技术就可能出现较大的偏差。

D.经过了20万年的寒冷气候，一个蛋壳碎片中的氨基酸已经分解，并且不适合再做鉴别使用。

E.在温暖的气候条件下更容易发现考古遗址中蛋壳的碎片。
