请问如果两个介宾结构做平行成分且介词一样的话,介词是否必须补出呢?
比如这道题:
Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies estimated to exist in the universe. A. that a black hole lies at the center of the Milky Way and of B. that a black hole lies at the Milky Way’s center and C. that there is a black hole lying at the milky Way’s center and D. of a black hole lying at the Milky Way’s center and E. of a black hole that lies at the center of the Milky Way and of OA:A 其中A补出of的原因是消除歧义,但是如果没有歧义的情况下还需要补出吗?
