请教02.10.25

25. Rocks form within Earth are called intrusive or plutonic rocks because the

A B

magma from which they form often intrudes into neighboring rock.

C D

d答案是A,form改为formed,作定语

我想问的是D选项,neighboring后的rock是单数,那么D好象要改为the neighboring rock

快乐公主

我理解后面的ROCK指的是岩层（岩浆侵入到邻近的岩层形成的岩石），所以是不可数的

前面指的是石头，是可数的

明白了，谢谢！
