阅读下面一段文言文

安重荣,小字铁胡,朔州人也。重荣有力,善骑射,为振武巡边指挥使。虽武夫,而晓吏事,其下不能欺。有夫妇讼其子不孝者,重荣拔剑授其父,使自杀之,其父泣曰:“不忍也!”其母从傍诟骂,夺其剑而逐之,问之,乃继母也,重荣叱其母出。重荣起于军卒,暴至富贵,而见晋高祖自藩侯得国,尝谓人曰:“天子宁有种邪?兵强马壮者为之尔!”虽怀异志,而未有以发也。是时,高祖与契丹约为父子,契丹骄甚,高祖奉之愈谨,重荣愤然,以谓“屈中国以尊夷狄,困已敝之民,而充无厌之欲,此晋万世耻也!”数以此非诮高祖。契丹使者往来过镇州,重荣箕踞慢骂,不为之礼,或执杀之。是时,吐浑白氏役属契丹,苦其暴虐,重荣诱之入塞。契丹数遣使责高祖,并求使者,高祖对使者鞠躬俯首,受责愈谨,多为好辞以自解,而姑息重荣不能诘。天福六年夏,契丹使者拽剌过镇,重荣侵辱之,拽剌言不逊,重荣怒,执拽剌;又为书以遗朝廷大臣、四方藩镇,皆以契丹可取为言。高祖患之,为之幸邺,报重荣曰:“前世与虏和亲,皆所以为天下计,今吾以天下臣之,尔以一镇抗之,大小不等,无自辱焉!”重荣谓晋无如我何,反意乃决。重荣虽以契丹为言,反阴遣人与幽州节度使刘晞相结。契丹亦利晋多事,幸重荣之乱,期两敝之,欲因以窥中国,故不加怒于重荣。 其冬,安从进反襄阳,重荣闻之,乃亦举兵。是岁,镇州大旱、蝗,重荣聚饥民数万,驱以向邺,声言入觐。高祖遣杜重威逆之,兵已交,其将赵彦之与重荣有隙,临阵卷旗以奔晋军。重荣闻彦之降晋,大惧,重荣以吐浑数百骑守牙城,重威使人擒之,斩首以献,高祖御楼受馘,命漆其首送于契丹。

Small, pink and very ugly. Hardly the qualities of a star, but they describe the deformed mouse that was the media darling at a recent science exhibition in Beijing. With a complex tissue structure in the shape of a human ear grafted on to its back, the rosy rodent was a stunning symbol of the serious strides China is making in the field of biotechnology.

China is fast applying the latest life-science techniques learned from the West to aggressively pursue genome research. It’s establishing its own centers of technical excellence to build a scientific base to compete directly with the United States and Europe. With a plentiful supply of smart young scientists at home and lots of interest abroad biotechnology is on the brink of a boom in China. And in the view of foreign scientists, Beijing is playing a clever hand, maximizing the opportunities open to them.

For the moment, the cooperation exists mostly with Europe and the U. S. But Asia’s other biotech leaders, Japan, Singapore and Korea, also are recognizing China’s potential as an attractive low-cost base to conduct research. These partnerships—and China’s advancement in the field of biotechnology—could help benefit the rest of Asia: China’s rapid progress in improving crop yields will address food-security concerns in the region. In addition, China is more likely to focus on developing cheap technology that its predominantly poor population and those of other Asian countries—can afford.

There remain, however, serious barriers to the development of a p biotech industry. Among them are a poor domestic legal framework, weak enforcement of intellectual-property rights and loose adherence to international standards. China is a signatory of the International Bio Safely Protocol, which should mean adherence to global standards governing the conduct of field trials. But some observers are skeptical. "The regulations look good, but I haven’t met one scientist who believes they are being fully adhered to," says a European science analyst.

If shortcuts are taken, then some of the recent scientific achievements trumpeted in the official press may never make it to market. But no matter how strict lab test are, other problems lie in wait. For example, there is a number of tasks it would take years to fulfill in the patents office, says one lawyer, leaving innovators with little protection if they take a product to market in China.

Japan, Singapore, and Korea will also be interested in cooperating with China in biotechnology because ().

A. it has made extraordinary contributions to the world

B. it has large supplies of talents and advanced research centers

C. its research focuses on the benefits of all Asian countries

D. its cooperation with the U. S. and Europe proves profitable
