[解析]
As is know to all, over seventy percent of our planet is covered by sea, that is rich in salt as well as fish. What's more, there is a great deal of oil or gas under the sea. In other words, the sea is the place with so many important things we live in. However, with the world population risen rapidly, overfishing has become a serious problem. Every day a lot of rubbish and waste water are poured into the sea, so the sea is heavy polluted. As∧ result, the number of fish have obviously declined. Besides, some are dying out or have beendisappeared. Therefore, it is time for everybody to protect the sea.
详解
1.know改为known.考查动词语态。句意:众所周知,地球上70%以上的土地被海洋覆盖,海洋不仅富含鱼类,而且还富含盐。分析句子可知,as指代后文一整句话,与know之间是被动关系,故know改为known.
2.that改为which.考查定语从句。句意:众所周知,地球上70%以上的土地被海洋覆盖,海洋不仅富含鱼类,而且还富含盐。分析句子可知,此处引导非限制性定语从句,先行词为sea,在从句中作主语,故用关系代词,故that改为which.
3.or改为and.考查连词。句意:此外,海底还有大量的石油和天然气。结合句意可知,oil与gas为并列关系,故or改为and.
4.the改为a.考查冠词。句意:换句话说,海洋是一个有很多我们赖以生存的重要东西的地方。结合句意,此处表示泛指,"一个地方"用不定冠词,故the改为a.
5.in改为on.考查介词。句意:换句话说,海洋是一个有很多我们赖以生存的重要东西的地方。固定搭配live on..."表示靠...生存"符合句意,故in改为on.
6.risen改为rising.考查现在分词。句意:然而,随着世界人口的迅速增长,过度捕捞已成为一个严重的问题。with+宾语+宾补的结构中,宾语population与rise之间是主动关系,用现在分词作宾补,故risen改为rising.
7.heavy改为heavily.考查副词。句意:每天都有大量的垃圾和废水被倒入大海,因此海洋受到严重污染。分析句子可知,此处修饰动词polluted,副词修饰动词,故heavy改为heavily.
8.result前加a.考查冠词。句意:因此,鱼类数量明显减少。固定搭配as a result表示"结果"符合句意,故result前加a.
9.have改为has.考查主谓一致。句意:因此,鱼类数量明显减少。主语为the number of...表示"...的数量",谓语动词用三单形式,故have改为has.
10.去掉been.考查动词语态。句意:此外,有些正在消亡或已经消失。主语some与disappear之间是主动关系,故去掉been.
