In 1943, when I was 4, my parents moved from Coeur d'Alene, Idaho, to Fairbanks, Alaska, where adventure was never very far away.

We arrived in the summer, just in time to enjoy the midnight sun. All that sunlight was fantastic for Mom's vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didn't care much about my bedtime.

Dad was a Railway Express agent and Mom was his clerk. That left me in a mess. I usually managed to find some trouble to get into. Once I had a little Are going in the dirt basement of a hotel. I had tried to light a barrel（桶） of paint but couldn't really get a good fire going. The smoke got pretty bad, though, and when 1 made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me

Mom and Dad were occupied in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mom rescued me. 1 hadn't turned 5 yet.

As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue on a metal handrail at school?

As for Leonhard Seppala, famous as a dog sledder (驾雪橇者), I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didn't realize what a superstar he was, but I do remember the ride well. I was wrapped (包裹) heavily and well sheltered from the freezing and blowing weather.

In 1950, we moved back to Coeur d'Alene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.

某工程项目施工采用了包工包全部材料的固定价格合同。工程招标文件参考资料中提供的用砂地点距工地4km。但是开工后，检查该砂质量不符合要求，承包人只得从另一距工地20kin的供砂地点采购。而在一个关键工作面上又发生了几种原因造成的临时停工：4月20日至4月26日承包人的施工设备出现了从未出现过的故障；应于4月24日交给承包人的后续图纸直到5月10日才交给承包人；5月7日到5月12日施工现场下了该季节罕见的特大暴雨，造成5月11日到5月14日该地区的供电全面中断。

试问：

若承包人对因业主原因造成窝工损失进行索赔时，要求设备窝工损失按台班计算，人工的窝工损失按工日计价是否合理如不合理应怎样计算？
