(本小题6分。)A注册会计师负责审计甲公司2011年度财务报表。甲公司2011年12月31日应收账款余额为3 000万元。A注册会计师认为应收账款存在重大错报风险, 决定选取金额较大以及风险较高的应收账款明细账户实施函证程序,选取的应收账款明细账户余额合计为1 800万元。相关事项如下:  (1)审计项目组成员要求被询证的甲公司客户将回函直接寄至会计师事务所,但甲公司客户X公司将回函寄至甲公司财务部,审计项目组成员取得了该回函,将其归入审计工作底稿。  (2)对于审计项目组以传真件方式收到的回函,审计项目组成员与被询证方取得了电话联系,确认回函信息,并在审计工作底稿中记录了电话内容与时间、对方姓名与职位,以及实施该程序的审计项目组成员姓名。  (3)审计项目组成员根据甲公司财务人员提供的电子邮箱地址,向甲公司境外客户Y公司发送了电子邮件,询证应收账款余额,并收到了电子邮件回复。Y公司确认余额准确无误。审计项目组成员将电子邮件打印后归入审计工作底稿。  (4)甲公司客户Z公司的回函确认金额比甲公司账面余额少150万元。甲公司销售部人员解释,甲公司于 2011年12月末销售给Z公司的一批产品,在2011年末尚未开具销售发票,Z公司因此未入账。A注册会计师认为该解释合理,未实施其他审计程序。  (5)实施函证的1 800万元应收账款余额中,审计项目组未收到回函的余额合计950万元,审计项目组对此实施了替代程序:对其中的500万元查看了期后收款凭证;对没有期后收款记录的450万元,检查了与这些余额相关的销售合同和发票,未发现例外事项。  (6)鉴于对60%应收账款余额实施函证程序未发现错报,A注册会计师推断其余40%的应收账款余额也不存在错报,无须实施进一步审计程序。  要求:针对上述第(1)至(6)项,逐项指出甲公司审计项目组的做法是否恰当。如不恰当,简要说明理由。

With the spread of inter-active electronic media a man alone in his own home will never have been so well placed to fill the inexplicable mental space between cradle and crematorium. So I suspect that books will be pushed more and more into those moments of travel or difficult defecation (1) people still don’t quite know what to do with.

When people do read, I think they’ll want to feel they are reading literature, or (2) something serious. (3) you’re going to find fewer books presenting themselves as no- nonsense and (4) assuming literary pretensions and being packaged as works of art. We can expect an extraordinary variety of genre, but with an underlying (5) of sentiment and vision.

Translators can only (6) from this desire for the presumably sophisticated. We can look forward to lots of difficult names and fantastic stories of foreign parts enthusiastically (7) by the overall worship of the "global village" Much of this will be awful and some wonderful, (8) don’t expect the press or the organizers of prizes to offer you much help in making the appropriate distinctions. They will be chiefly (9) in creating celebrity, the greatest enemy of discrimination, but a good prop for the (10) consumer.

Every ethnic grouping over the world will have to be seen to have a great writer--a phenomenon that will (11) a new kind of provincialism, more chronological than geographic, (12) only the strictly contemporary is talked about and (13) . Universities, including Cambridge, will include (14) their literature syllabus novels written only last year.

In short, you can’t go too far wrong when predicting more of the same. But there is a (16) side to this--the inevitable reaction against it. The practical things I would like to see happen--publishers seeking less to (17) celebrity through extravagant advertising, (18) and magazines (19) space to reflective pieces--are rather more improbable than the Second Coming (耶稣复临). But dullness never quite darkens the whole planet. In their own idiosyncratic fashion a few writers will (20) be looking for new departures.
