南、北面官制
参考答案：辽朝为了对生产、生活方式各不相同的多民族实行有效的统治，经过长期的探索确立的官制。这种新体制是在辽世宗继位后形成的，中央行政机构分别隶属于南北二枢密院，称为“南面官”和“北面官”。南面官用唐制，有三省六部之设，宰相有大丞相、同平章事、参知政事等；北面官采用契丹传统的部族官制度，有南北宰相府，南北大王府等机构。北面治宫帐、部族、属国，南面治汉人州县。辽朝中央官之所以分为南北，这是因为契丹人拜日，东向而尚东，在捺钵朝廷中，皇帝的殿帐东向，上朝时文武官员在殿帐前面左右分列，左侧即北面官，右侧则是南面官。这种政治体制真正确立了皇帝的绝对权威，将契丹部族纳入封建政治体制当中。
Big ocean fish have almost been endangered since the start of business fishing in the 1950s. 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 businesses and governments around the world. The magazine Nature published(发表)th  e 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(连接) to one boat. If these lines are joined together, they can reach one hundred kilometers. They hold thousands of sharp metal hooks(钩) to catch fish. Longline fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one 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. 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). 根据短文内容完成表格，每空一词。 What is happening to ocean fish?
