问题 单项选择题 A1型题

婴儿期每日热量及水的需要约是()

A.460kj/kg,150ml/kg

B.430kj/kg,130ml/kg

C.380kj/kg,120ml/kg

D.380kj/kg,110ml/kg

E.360kj/kg,100ml/kg

答案

参考答案:A

解析:热量由食物中的糖、脂肪、蛋白质供给,婴幼儿期约需热量460kj/(kg·d)。小儿的新陈代谢旺盛,加上小儿活动量大,体表面积相对大,水分蒸发多,所以需要增加水的供给量。乳幼儿约需100~150ml/(kg·d),随着年龄增长,水需要量相对减少。若摄水量少于60ml/(kg·d),可能发生脱水症状,若摄水量超过正常需要量,多余的水能从尿中排泄,如心、肾、内分泌功能不全时,可发生水中毒。故选A。

Pulling heavy suitcases all day in the summer is hard work, especially when you're a thin 14-year-old.That was me in 1940-the youngest and smallest baggage boy at New York City's Pennsyl-vania Railway Station.

After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I'd like to join them, thinking, "Everyone else is doing it."

When I got home that night, I told my dad what I wanted to do." You give an honest day's work," he said, looking at me straight in the eye."  They're paying you. If they want to do that, you let them do that."

I followed my dad's advice for the rest of that summer and have lived by his words ever since.

Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me. Now I teach my players to have respect for other people and their possessions. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he'd be gone.

Whether you're on a sports team, in an office or a member of a family, if you can't trust one another, there's going to be trouble.
