国务院审议褡正式批准实施国家发展改革委牵头编制的《黄河三角洲高效生态经济区发展规划》(以下简称《规划》)。这标志着黄河三角洲开发在国家战略层面上进入深入实施阶段。作为我国唯一一个以高效生态为特点的经济区,它对于增创山东省发展新优势,实现经济又好又快发展具有十分重要的意义。
黄河三角洲开发建设在国家战略层面的推动,具有重要的历史和现实意义,随着一些措施的逐步实施和各项政策的落实到位,黄河三角洲发展具有光明前景。
黄河三角洲将成为山东新的经济增长极,黄三角处于天津滨海新区引发的产业北移的中间地带,拥有大量国家鼓励开发的盐碱地和荒草地,面临着主动接受辐射、扩大交流合作、集聚生产要素、吸引各方投资、加快开放开发的战略机遇。在国家的大力支持下,抓住并用好战略机遇,突出高效生态主题,进一步优化环境,大规模承接国内外产业转移,黄河三角洲地区交进入快速崛起阶段。预计到2015年将突破9300亿元。建成全省新的经济增长极,为经济文化强省提供强力支撑。

A good modern newspaper is an extraordinary piece of reading. It is remarkable first for what it contains the range of news from local crime to international politics, from sports to business to fashion to science, and the range of comment and special features (特定) as well, from editorial page to feature articles and interviews to criticism of books, art, theatre and music. A newspaper is even more remarkable for the way one reads it never completely, never straight through, but always by jumping from here to there, in and out glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next. A good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interested in. What brings this variety together in one place is its topicality (时事性), its immediate relation to what is happening in your world and your locality now. But immediacy and the speed of production that goes with it mean also that much of what appears in a newspaper has no more than transient (短暂的) value. For all these reasons, no two people really read the same paper: what each person does is to put together out of the pages of that day’s paper, his own selection and sequence, his own news paper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness as you modify and apply the techniques of reading.
A modem newspaper is remarkable for all the following except its ______.
A. wide coverage B. uniform styleC. speed in reporting news D. popularity
