Scientists have recently found evidence thatblack holes—regions of space in which matter is so concentrated and the pull ofgravity so powerful that nothing, not even light, can emerge from them—probablyexist at the core of nearly all galaxies and the mass of each black hole isproportional to its host galaxy.
proportional to that(the mass概念要对等) of its host galaxy】
(A) exist at the core of nearly all galaxies and themass of each black hole is proportional to
(B) exist at the core of nearly all galaxies and thatthe mass of each black hole is proportional to that of
(C) exist at the core of nearly all galaxies, and thatthe mass of each black hole is proportional to
(D) exists at the core of nearly all galaxies. andthat the mass of each black hole is proportional to that of
(E) exists at the core of nearly M galaxies and the massof each black hole is proportional to that of
选B
【Scientists have recently foundevidence that black holes[逻辑主语](—插入语修饰holes) exist[逻辑谓语] at the core(of…) and that the mass of each blackhole is
(1)the blacks exist主谓一致，杀D/E
(2)and出现注意平行，that…and that…杀A
(3)比较对象要对等，用核心指代补出同一比较的名词—杀C，应该是mass和mass比较
注意：出现有核心指代的选项，往前面找指代的名词，检查单复数是否合理
这个题还是不懂 |
