求谏
吴兢
太宗威容俨肃，百僚进见者，皆失其举措。太宗知其若此，每见人奏事，必假颜色，冀闻谏诤，知政教得失。贞观初，尝谓公卿曰：“人欲自照，必须明镜；主欲知过，必藉忠臣。主若自贤，臣不匡正，欲不危败，岂可得乎？故君失其国，臣亦不能独全其家。至于隋炀帝暴虐，臣下钳口，卒令不闻其过，遂至灭亡，虞世基等，寻亦诛死。前事不远，公等每看事有不利于人，必须极言规谏。”
贞观元年，太宗谓侍臣曰：“正主任邪臣，不能致理；正臣事邪主，亦不能致理。惟君臣相遇，有同鱼水，则海内可安。朕虽不明，幸诸公数相匡救，冀凭直言鲠议，致天下太平。”谏议大夫王珪对曰：“臣闻，木从绳则正，后从谏则圣。是故古者圣主必有争臣七人，言而不用，则相继以死。陛下开圣虑，纳刍荛，愚臣处不讳之朝，实愿罄其狂瞽。”太宗称善，诏令自是宰相入内平章国计，必使谏官随入，预闻政事。有所开说，必虚己纳之。
贞观五年，太宗谓房玄龄等曰：“自古帝王多任情喜怒，喜则滥赏无功，怒则滥杀无罪。是以天下丧乱，莫不由此。朕今夙夜未尝不以此为心，恒欲公等尽情极谏。公等亦须受人谏语，岂得以人言不同己意，便即护短不纳？若不能受谏，安能谏人？”
贞观八年，太宗谓侍臣曰：“朕每闲居静坐，则自内省，恒恐上不称天心，下为百姓所怨。但思正人匡谏，欲令耳目外通，下无怨滞。又比见人来奏事者，多有怖慑，言语致失次第。寻常奏事，情犹如此，况欲谏诤，必当畏犯逆鳞。所以每有谏者，纵不合朕心，朕亦不以为忤。若即嗔责，深恐人怀战惧，岂肯更言！”
贞观十六年，太宗谓房玄龄等曰：“自知者明，信为难矣。如属文之士，伎巧之徒，皆自谓己长，他人不及。若名工文匠，商略诋诃，芜词拙迹，于是乃见。由是言之，人君须得匡谏之臣，举其愆过。一日万机，一人听断，虽复忧劳，安能尽善？常念魏征随事谏正，多主朕失，如明镜鉴形，美恶必见。”因举觞赐玄龄等数人勖之。   （《贞观政要》）

The rapid growth of Smartphones and electronic tablets（平板电脑）is making the Internet favourite for Americans reading news, a report said.

News consumption online increased 17% last year from the year before. Television news, newspapers, radio and magazines all lost audience last year. For the first time, the number of people who get news online at least three times a week is larger than the number of people who get news from the newspapers. TV news has been the most popular since the 1960s. It has replaced the afternoon newspapers. But now the online news seems to be more popular than the TV news.

People are used to having the Internet available on phones or small tablets. In December, 2010, 41% of Americans said they got most of their news on the Internet, more than double the 17% who said that a year earlier, the report said. In January, 2011, 7% of Americans owned electronic tablets, nearly double what it was three months earlier. It was the fastest-growing new digital technology, ahead of mobile phones when they were introduced. The online ad income was expected to surpass（超过）print newspaper ad income for the first time in 2010.

The news business used to be the intermediary（中介）. You needed newspapers and TV stations to reach your customers. In this age of the computer, it’s the software developers that you need.
