Oceans cover 2/3 of the earth. Our knowledge to
认识却是很少的一部分，但海洋对人类的生存和发展有
oceans is very limited, while oceans play a significant role to the very survival and development of mankind.
重大的意义。海底地貌和构造的不断变化不仅仅是海洋本
The unending change of landscape and structure under the oceans effects not only the
身的变化，它对人类的生存环境也有着很大的影响。
ocean itself but also the living enviroment of our kind to a great extent.
海底地貌与大陆地形不同，它一起伏不平的地形为特征。
The landscape under oceans differs from that on the earth. It features with fluctuant landforms.
海底山脉、海底火山、裂谷、大洋中脊等等，构成了丰富
Mountains, volcanos, valleyes and fastigiums consist the various world beneth the ocean.
的海底世界。而我们只有对海洋地质有正确的认识，并熟
We can only make oceans produce more wealth for us if we attained correct assessment on
练掌握海底勘探技术、方法，才能使海洋为人类造就更多
ocean geology and mastery on reconnitring under oceans.
财富。

The sea 占地 ball area about 2/3, our humanity to the sea the understanding and the understanding actually is a very few part, but the sea has the significant significance to humanity's survival and the development. The seabed landform and the structure unceasing change not merely is the sea itself change, it also has the very tremendous influence to humanity's survival environment. The seabed landform and the mainland terrain are different, an its fluctuation uneven terrain is a characteristic. The seabed sierra, the oceanic volcano, the rift valley, the ocean 中脊 and so on, constituted the rich seabed world. But we only have to the sea geology have the correct understanding, and skilled grasps the seabed exploration technology, the method, can cause the sea to accomplish more wealths for the humanity.

海底山脉、海底火山、裂谷、大洋中脊等等，构成了丰富的海底世界。
Seamounts, underwater volcanoes, Rift Valley, the mid-ocean ridge,constitute a rich world of the ocean floor.
而我们只有对海洋地质有正确的认识，并熟练掌握海底勘探技术、方法，才能使海洋为人类造就更多财富。
Only when we have a correct understanding to the marine geology and master the seabed exploration technology,can we have the ocean contribute more wealth to human being.

记得帮我加纷哦！

找个翻译软件就可以啦 要是真不行 就到学校找老师去吧 呵呵

we all know that oceans are very important to humans survive and development.but we know only a little about the ocean,which covers 2\3 of the earth.下面的和楼上的一样
