A、于是予有叹焉。古人之观于天地、山川、虫鱼、草木、鸟兽，往往有得，以其求思之深而无不在焉。夫夷以近，则游者众，险以远，则至者少，而世之奇伟瑰怪非常之观，常在于险远，而人之所罕至也，故非有志者不能至也。

B、有志矣，不随以止也，然力不足者，亦不能至焉。有志与力，而又不随以怠，至于幽暗昏惑无物以相之，亦不能至焉。然力足以至焉，于人为可讥，在己为有悔；尽吾志而不能至者，可以无悔也，岂熟能讥之乎？此余之所得也。

C、思厥先祖父，暴霜露，斩荆棘，以有尺寸之地。子孙视之不甚惜，举以与人，如弃草芥。今日割五城，明日割十城，然后得一夕安寝，起视四境，秦兵又至也。然则诸侯之地有限，而暴秦之欲无厌，奉之弥繁，侵之愈急，故不战而强弱胜负已判矣。至于颠覆，理固宜然。故人云：“以地事秦，犹抱薪救火，薪不尽，火不灭。”此言得之。

D、呜呼！以赂秦之心封天下之谋臣；以事秦之地礼天下之奇才；并力西向，则吾恐秦人食不得下咽也。呜呼！有如此之势，而为秦人积威之所劫，日削月割，以趋于亡。为国者勿使为积威之所劫哉！

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.

It can be conclude from the passage that newspaper readers ______.

A. apply reading techniques skillfully
B. jump from one newspaper to another
C. appreciate the variety of a newspaper
D. usually read a newspaper selectively
