Question

In science fiction we read of flying saucers travel through ( )space,so people want to have ( )better knowledge of the universe
A the ,a
B /,/
C the ,/
D /,a
,space前面不能加the的吗,knowledge是可数的吗

Answer 1

space指太空时不能加冠词,如in space,加定冠词意思就变了,in the space是在...空间里.当knowledge指一个人对某一具体事物或具体学科的知识时,可以与不定冠词a连用（不管有无定语）
如：He has an wide knowldge of history.
当knowledge泛泛地指知识的时候,它是个不可数名词,不能与不定冠词a连用
如：Knowledge is power.
