如图是我们正常人每天应摄取各类营养物质的食物金字塔．
（1）位于塔底的五谷类是人体每天应摄取最多的，它含有的营养素最多的一种是______，它主要为人体机体活动和维持体温提供所需的______．
（2）某校食堂中餐食谱如下：
主食：大米饭
配菜：红烧肉、煎鸡蛋、炸鸡腿、

考虑到各种营养成分的均衡搭配，应该增加的配菜是______．
（1）从食物金字塔来看，人体每天应摄取最多的是五谷类、面包、大米等，它们中主要含有糖类，糖类在人体内最终消化为葡萄糖，然后大部分在酶的作用下氧化分解生成二氧化碳和水，同时放出能量（或热量）供人体进行生命活动．
（2）食谱中的大米饭中主要含有糖类，红烧肉中主要含有蛋白质和油脂以及水和少量无机盐，煎鸡蛋、炸鸡腿中主要含有蛋白质和油脂，缺乏的是维生素，所以应添加蔬菜和水果，如青菜．
故答案为：（1）糖类；能量（或热量）；（2）青菜．

| According to Gerry Smith and Shaun Belding, writers of three books on dealing with people who make troubles at the office, how you get on with the people described below can improve the working environment for everyone. （1）People who blame (指责) others including (包括) you Call them on it by saying, "Why is it always someone else's fault (错误)?" They may laugh over what you said or become sorry. Both of them mean your point has been taken. （2）People who take your ideas as their own Put your names on anything you write or make. If someone does it at a meeting, point it out at once- using humour（幽默）if possible. Later follow the person and tell him or her, "Don't do that again." （3）People who often break in Don't put up with it. Say coolly but firmly (坚定地), "Please wait while I finish talking." （4）People who embarrass (使人窘迫) you in public Put them on the hot seat by saying later, "I'm sure you didn't want to embarrass me, but you did." （5）People who don't follow through Of course you cannot order another worker, but you can try telling them they are not helpful and that you'll report it to the boss (老板) if they go on. Then do it. （6）People who tell lies Talk straight to him or her when it's about you. Or ask the boss for help, who can tell him or her, "There are lies going around. Can I get you to straighten them out for me?" |
