背景材料：中國南?？扇急?013年開鉆取樣，可供中國用135年。根據(jù)掌握的情況，中國南海的可燃冰可能主要集中在東沙、西沙和神狐等海域。2017年5月18日，南?？扇急嚥沙晒?。

可燃冰，又名天然氣水合物，被稱為能滿足人類使用1000年的新能源，是今后替代石油、煤等傳統(tǒng)能源首選。它是甲烷和水在海底高壓低溫下形成的白色固體燃料，可以被直接點燃。1立方米可燃冰可釋放出160-180立方米的天然氣，其能量密度是煤的10倍，而且燃燒后不產(chǎn)生任何殘渣和廢氣。

參考譯文

Combustible ice, also known as the natural gas hydrate（NGH）, is referred to as a new source of energy that can meet humans’needs for 1,000 years and the preferred alternative taking the place of conventional energy sources such as oil and coal in the future. It is a white solid fuel composed of methane and water at low temperature and high pressure at the bottom of the ocean floor, which can be ignited directly. One cubic meter of flammable ice can release 160 to 180 cubic meters of natural gas, which is 10 times more energy than coal and does not produce any residue or waste gases after burning.

翻譯點撥

Combustible ice, also known as the natural gas hydrate（NGH）, is referred to as a new source of energy that can meet humans’needs for 1,000 years and the preferred alternative taking the place of conventional energy sources such as oil and coal in the future.

該句中的主語為Combustible ice；also known as the natural gas hydrate（NGH）為主語的同位語；is referred to as的賓語有兩個，分別是a new source of energy和the preferred alternative，其中and起并列連接賓語的作用；that can meet humans’needs for 1,000 years和taking the place of conventional energy sources such as oil and coal in the future分別是that引導的定語從句和-ing引導的定語從句來修飾a new source of energy和the preferred alternative。另外，要注意，take the place of 和take place的區(qū)別：take the place of意為取代……而take place意為發(fā)生。少一個定冠詞the和多一個定冠詞the意思就有天壤之別。

It is a white solid fuel composed of methane and water at low temperature and high pressure at the bottom of the ocean floor, which can be ignited directly.

該句composed of methane and water at low temperature and high pressure at the bottom of the ocean floor作了a white solid fuel的后置定語；which can be ignited directly則為主句的非限制性定語從句。
