P公司在销售环节，采用了订货与核准购货方信用职务分离的控制制度，目的是为了防止在销售过程中吃回扣或不能及时回收销货款。由于执行者没有认真履行订货合同与批准销售的职权分离的内控制度，致使公司本年度内销货交易货款的55%不能按时回收，给公司造成了巨大的财务损失。 A注册会计师在实施审计中，对其内部控制制度评价时根据以往的经验，认为公司在订购与销货方面不存在问题，没有进行相关的测试，致使会计报表出现较大数额的错报。 请回答： (1)什么是普通过失和重大过失A注册会计师在对P公司的审计中属于何种过失 (2)A注册会计师及其所在的会计师事务所应承担什么法律责任可能受到哪些处罚

                                          A letter to Edward,a columnist (报刊专栏作家)

Dear Mr. Expert,

     I grew up in an unhappy and abusive home. I always promised myself that I'd get out as soon as possible.

Now, at age 20, I have a good job and a nice house, and I'm really proud of the independence (独立) I've

achieved.

     Here's the problem: several of my friends who still live with their parents wish they had places like mine-so

much so that they make mine theirs.

     It started out with a couple of them spending the weekends with me. But now they seem to take it for

granted that they can show up any time they like. They bring boyfriends over, talk on the phone and stay out

forever.

     I enjoy having my friends here sometimes-it makes the place feel comfortable and warm-but this is my

home, not a party house. I was old enough to move out on my own, so why can't I seem to ask my friends

to respect my privacy (隐私) ?

                                                                                                                                                  Joan

                                                       Edward's reply to Joan

Dear Joan,

     If your family didn't pay attention to your needs when you were a child, you probably have trouble letting

others know your needs now.

     And if you've gathered your friends around you to rebuild a happy family atmosphere (气氛), you may

fear that saying no will bring back the kind of conflict (冲突) you grew up with-or destroy the nice atmosphere

you now enjoy. You need to understand that in true friendship it's okay to put your own needs first from time

to time.

     Be clear about the message you want to send. For example, "I really love your company but I also need

some privacy. So please call me before you come over."

                                                                                                                                               Edward
