Big ocean(海洋)fish have almost disappeared from the world since the start of business fishing in the 1950’s．The scientists found that the number of large fish has dropped by 90 percent in the past fifty years．The study took ten years．The researchers collected records from fishing business and governments around the world．The magazine Nature published the findings．
The scientists say the common way called longline fishing is especially harmful to large fish．This way includes many fishing lines that are connected to one boat．If these lines are joined together，they can reach one hundred kilometers．They hold thousands of sharp metal hooks to catch fish．Longline fishing is especially common in the Japanese fishing industry．Records show that Japanese boats used to catch about ten fish for every hundred hooks．The study says longline fishing boats now might catch one fish per hundred hooks．
The scientists say business fishing can destroy groups of fish much faster than in the past．The study suggests that large fish can disappear almost completely from new fishing areas within ten to fifteen years．Ocean life system could be destroyed．
It’s not the only worry that the number of large fish is becoming smaller and smaller．What’s worse．they are smaller in size than their ancestors(祖先)．

最高法再审改判聂树斌无罪，法制进步新体现。

材料一：12月2日，最高人民法院第二巡回法庭对聂树斌案再审公开宣判，认为原判认定聂树斌犯罪的事实不清、证据不足，改判聂树斌无罪。此时，距离聂树斌被执行死刑已经过去21年。聂树斌案是司法机关根据疑罪从无、证据裁判原则依法纠错的重大案件。

材料二：聂树斌案改判过程中旨在保障程序正义的各项制度探索，为公正司法提供了有益的经验。

以2012年我国《刑事诉讼法》修改和“两个证据规定”的出台为标志，我国刑事诉讼制度确立了保障人权、疑罪从无、证据裁判、从严掌握死刑案件证据标准等原则和制度。最高人民法院直接提审，最高人民法院指定异地复查案件，再审，复查、再审环节充分保障当事人参与权、阅卷权和公众知情权，召开听证会等有益形式，为处理社会有广泛影响的重大案件提供了很好的参照。最终“让人民群众在每一个司法案件中感受到公平正义”。
