Thus a proportion of the total volume of any sediment, loose or cemented, consists of empty space. Most crystalline rocks are much more solid; a common exception is basalt, a form of solidified volcanic lava, which is sometimes full of tiny bubbles that make it very porous.

因此这一个部分空空的空间所占据。大多数水晶石更为坚硬；一个例外是玄武岩，它是坚硬火山岩的一个部分，它有时充满气泡，这些气泡使它渗透性强。

非限定定语从句也可以代指宾语。

 

 

 

loose ：宽的

solidified ：坚硬的

Cemented：灌水泥的

Proportion:部分

Porous：渗透的

Basalt：玄武岩

crystalline ：水晶

Permeable：可渗透的

volcanic：火山

Lava： 熔岩

Sediment：沉淀物

 

According to paragraphs 6 and 7, why is basalt unlike most crystalline forms of rock?

 

为什么玄武岩不像大多数水晶组成？

 

A.  It is unusually solid---错，不是solid，是porous。

B.  It often has high porosity.

C.  It has a low proportion of empty space.----错，是high proportion，不是low proportion。

D.  It is highly permeable.---错，不是permeable高渗的，是porosity多孔的。
