单项选择题

   刘醒龙是近年来文坛上出现的颇具创作实力的作家。他的作品曾多次获奖,另有代表作《凤凰琴》被改编成电影及电视剧。

  比起一些成名多年的作家,刘醒龙的小说有突出的特色,那就是生活积累丰厚。他的创作和冲动更多来自对生活的体味和发现,而不是来自理念,因而就有了浓重的生活味、人情味,或人间烟火味。

  中篇小说《分享艰难》并没有一个中心事件,而只有一个中心人物做自我批评――河西镇的镇委书记孔太平,小说情节围绕他而递次展开。

  孔太平并不是一个楷模式的领导干部。他是一个有些个人野心、想成就一番事业、聪明且有些狡诈的人。他似乎执著于目的而不十分在意为达到目的所采取的取的手段,而且他所采取的手段常常是超常规的,十分不合规矩却能达到想要达到的目的。然而,他的可爱之处就在于他的目的并非只是个人的荣辱沉浮,更多的是对自己职位的尽责,甚至他会羞于为了自己的前途而做他认为不该做的事。他的原则性与魄力和他的变通与不得已屈服都一样鲜明地存在着;于是,作者笔下的这个人物便不很高大却很可爱,不很神圣却很可亲地出现在读者面前。他是一个小地方官,烦恼的事不大却很多,所以他会给读过这部小说的人留下一个实实在在的、有些说不清是什么滋味的印象。

文中划线部分,说明了孔太平()

A.采取正常手段而达到目的

B.采取通常的手段而达到目的

C.采取必要的手段而达到目的

D.采取非法的手段而达到目的

     Japanese people,who never miss a chance to be photographed,were lining up to get their

pictures on a postage stamp.Vanity(虚荣)stamps with personal photographs went on sale

for the first time in Japan as part of an international postage stamp exhibition.The customer's

photo was taken with a digital camera and then printed on stamp sheets,a process that takes

about five minutes.Sold in a sheet of 10 stamps for $8.80,little more than the cost of lunch

in Tokyo,each stamp printed a different scene from a traditional painting along with the photo.

     The stamps can be used normally to mail a letter,and postal officials hope they will help

encourage interest in letter writing in the Internet age."Certainly e-mail is a useful method of

communication,but letters are fun in a different way,"said Hatsumi Shimizu an official in the Post

Ministry."We want to show young people that letters can be fun too."

     While similar stamp sheets appeared in Australia in 1999 and are now sold in some nations

and territories, Japan's fondness for commemorative photos is likely to make them especially

popular here.Indeed,officials had prepared 1 000 sheets but they were sold out in less than

30 minutes.Although the stamps are currently only available as a special service during the

exhibition,postal officials said they may start selling them on a regular basis in the future.
