2010年年初，A公司投资兴建小水电站项目获批。当地某负责人表示，为节约成本，可为A公司指定可靠的设计和施工单位。A公司接受了这一建议，将设计任务交给了该县水利局干部李某，当水电站工程进行到中途时，有关部门发现李某不具备注册结构工程师资质，对A公司处以罚款。A公司不得不让市水利勘测设计院重新设计，但具体工程仍按李某设计的图纸进行。施工任务也被交给了由某负责人指定的一家建筑公司，但该建筑公司从未从事过水利工程项目。2012年，水电站工程被施工方宣布"竣工"，A公司共投入了1000万元。由于存在诸多质量问题，水电站建成后无法正常使用。经当地质检部门鉴定：工程设计存在重大问题，施工未严格依据合规的设计图纸进行，使用的工程材料不符合水电站建设要求，一旦大坝遇到一定程度的水量，将会因为耐力强度不够而被冲垮。更为严重的是，由于该水电站存在严重的质量问题，直接威胁到下游三个村庄村民的人身财产安全。要求：（1）根据《企业内部控制应用指引第11号--工程项目》的规定，分析该工程项目存在哪些不合理之处，并说明理由。（2）简述工程项目需要关注的主要风险。

All right! Enough cookies,cola, and chips! It seems that junk food is all that the children want to eat these days.Television controls their tastes.The kids see well-known personalities eating potato chips, candy and other processed food, and they want to be like their heroes.How do they do it?They eat the same food. I wish there were more characters like old Popeye（大力水手）, the sailor, who ate spinach（菠菜） and not French fries.

Now I don't expect my children to eat healthy food because I like brown rice, beans, and fresh vegetables. I'm glad to cook traditional meals of meat and potatoes for them. I really can't be too upset with the kids because most adults aren't careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can't eat hot dogs, with all those preservatives（防腐剂）, and hamburgers are filled with chemicals so that they look better. Besides the meat, they had sugar-filled cookies and cake, and of course, chips. I don't want the world to change because of me, but I think people should realize that there are alternatives(选择) to eating meat. They always tell me that I probably don't get my essential(必要的) proteins. I feel better than ever and I'm sure that it's because I'm a vegetarian(素食主义者). I would really like to see more television advertisements which show the benefits of good, healthy, natural food.
