结合所学知识,完成下面小题。

1自然资源分为可再生资源和非可再生资源,下列自然资源与天然气属于同一类的是( )

A.温泉、风能B.核能、太阳能C.水能、石油D.煤炭、花岗岩

2实行阶梯气价有利于( )

A.减少天然气用量,根治大气污染

B.增加天然气用量,加大供气压力

C.引导居民合理用气、节约用气

D.降低天然气公司运营成本

【答案】

1D

2C

【解析】

可再生资源是指被人类开发利用后,可以在较短时间内更新、再生,或者能够重复利用、循环使用的自然资源,如气候资源、生物资源、水资源和土地资源等。非可再生资源是指经人类开发利用后蕴藏量不断减少,在相当长的时间内不可能再生的自然资源,主要是指自然界的各种矿物、岩石和化石燃料,例如金属矿产、非金属矿产、煤炭、石油、天然气等矿产资源。土地、森林、太阳能、水属于可再生资源,铁矿、煤矿、天然气属于非可再生资源。

1可再生资源是指被人类开发利用后,可以在较短时间内更新、再生,或者能够重复利用、循环使用的自然资源,如气候资源、生物资源、水资源和土地资源等。非可再生资源是指经人类开发利用后蕴藏量不断减少,在相当长的时间内不可能再生的自然资源,主要是指自然界的各种矿物、岩石和化石燃料。金属矿产、非金属矿产、煤炭、石油、天然气等矿产资源;核能、石油、煤炭、花岗岩与天然气同属于非可再生资源,温泉、风能、太阳能、水能同属于可再生资源。故选:D

2我国自然资源总量丰富,但由于人口众多,人均占有量少,随着经济的发展,资源的需求量不断增加,这就需要我们节约使用资源,实行阶梯气价的方法,有利于引导居民合理用气、节约用气。故选:C

本题主要考查自然资源的分类和保护,理解解答即可。
