Quasars, at billions of light-years from Earth the most distant observable objects in the universe, believed to be the cores of galaxies in an early stage of development.
45. Quasars, at billions of light-years from Earth the most distant observable objects in the universe, believed to be the cores of galaxies in an early stage of development. (A) believed to be (B) are believed to be (C) some believe them to be (D) some believe they are (E) it is believed that they are C The clause some believe them to be does not supply a verb to accompany quasars as the subject of the sentence, and the clause supplies an object “them” so that quasars cannot be the object, making the sentence ungrammatical.绿色这句啥意思?,them 不能指代quasars吗?这样的话quatars不就是object了吗?
我理解: 由于插入语可以直接无视,注意:要连同逗号一起拿掉。原句即可简化为: (Quasars some believe them) to be the cores of galaxies in an early stage of development. 重点在于括弧内,结合OG解释就变成: 如果加了them,原句就ungrammatical了,因为Quasars 和some 都成为独立的主语,而一山不容二虎,两主语ungrammatical. 反观如果去掉them,原句便成为: Quasars some believe to be the cores of galaxies in an early stage of development. 正常语序可以修正为: Some believe Quasars to be the cores of galaxies in an early stage of development. 去掉Them后此时Quasars可作为believe的Object,如此解决了双主语的问题
