（二）2011年12月，甲市乙县国税局对锦绣服装公司进行税务检查时发现，该公司一笔账务处理异常。乙县国税局认为，该公司购进的某批布料用于 非应税项目，其进项税额276000元不应抵扣。乙县国税局决定：依法追缴该公司少缴的增值税税款，并加收相应的滞纳金。2012年2月1日，乙县国税局 向该公司送达《税务行政处罚事项告知书》，拟处少缴增值税税款的50%即138000元罚款。该《告知书》内容未涉及公司的听证权利问题。次日，该公司法 定代表人吴某和财务负责人楚某找到乙县国税局工作人员齐某，就有关事实和依据问题以口头形式向其作了全面的陈述和申辩，主要理由是：公司购进该批布料后， 将其全部用于委托他人加工服装，收回后全部用于对外销售，并缴纳了增值税。齐某当场劝吴某和楚某不要再狡辩和发牢骚，吴某和楚某只好作罢。2012年2月 7日，吴某打电话给齐某说：“我们公司要求举行听证。”对此，齐某口头解释说：“你们有权要求听证，但是，法律规定听证要求得书面提出，3天的听证申请期 限已经过了”。吴某听后就没有提交听证申请书。2012年2月10日，乙县国税局向该公司送达《税务行政处罚决定书》，对该公司处以少缴增值税税款的 50%即138000元的罚款。该公司对处罚不服，次日即向甲市国税局提出复议申请，请求撤销处罚决定。理由是：乙县国税局不依法告知听证权利和举行听 证，对公司提出陈述和申辩意见不进行复核，处罚决定程序违法。甲市国税局复议人员在审查乙县国税局的税务行政处罚案卷时发现：没有锦绣服装公司提交的陈述 申辩的书面材料和口头陈述申辩的笔录材料;在一份检查笔录上注明了“无陈述申辩”字样，但没有公司盖章或者公司有关人员签字。复议期间，乙县国税局不能提 供对锦绣服装公司提出的陈述和申辩意见进行复核的证据。

第三部分：阅读理解（共15小题，每题2分，满分30分）

阅读下列短文，从每题所给的四个选项A、B、C、D中，选出最佳答案。

The competition for Hollywood's highest honors has begun with the announcement Tuesday in Los Angeles of this year's nominations（提名）for the 82nd Academy Awards. 

As expected, James Cameron's Avatar received a Best Picture nomination. And Cameron's former wife, Kathryn Bigelow, was nominated for The Hurt Locker, a war film set in Iraq.  Bigelow would be the first female director to win Best Picture.

Hollywood author Tom O'Neil says the race between the former couple adds more drama to the competition.  "We have a classic David-versus-Goliath battle here for Best Picture at the Oscars. The most successful movie ever made, Avatar, up against a movie that lost money, The Hurt Locker - directed by the former Mrs. Goliath, Kathryn Bigelow. This race has all kinds of dimensions（程度） to it," he said.

For the first time since 1943, 10 films are competing for the Best Picture award.

Entertainment reporter Sam Rubin says that means greater interest in the Academy Awards ceremony March 7th.  "The Oscars are a television show," he explained. "So the idea is to increase ratings and interest in the television show."

District Nine represents another departure -- a tale of science fiction -- like the box office hit Avatar.

"No science-fiction movie has ever won Best Picture. Only two have been nominated in the past: Star Wars and E.T. Two are nominated for Best Picture now," O'Neil said.

Best Picture nominee Precious is a drama about the struggles of an inner-city teen, and its director, Lee Daniels, is also nominated in the Best Director category. He is first African-American director to get a Best Picture nomination. 

The other Best Picture nominees are An Education, The Blind Side, Inglourious Basterds, A Serious Man, and Up in the Air.

Over the past 20 years, the film with the most nominations has won best picture 15 times --making Avatar and The Hurt Locker the favorites.
