Astronomers have uncovered evidence that a star that was as bright as the full moon exploding into view 340,000 years ago, emitting dazzling radiation that could have disrupted Earth's protective ozone layer and sunburned our Stone Age ancestors.
that a star that was as bright as the full moon exploding into view 340,000 years ago, emitting
that a star as bright as the full moon exploded into view 340,000 years ago, emitting
of a star that was as bright as the full moon exploding into view 340,000 years ago and that it emitted
of a star as bright as the full moon, exploding into view 340,000 years ago and emitting
of a star as bright as the full moon that exploded into view 340,000 years ago and that emitted
A. evidence that… 从句中的句子无谓语:a star (that was as bright as the full moon) exploding…;emitting看似与exploding平行,但缺少连词建立这两个动词之间的关系。
B. 正确,详见“句子结构”分析。
C. Evidence of a star不如evidence that…表达有效。该选项,that成为修饰star的定语从句,整个句子的主结构变成:Astronomers have uncovered evidence of a star――宇航员发现了关于某颗恒星的证据,至于原句要强调的证据的具体内容,被定语从句给“淹没”了;该选项存在平行的两个定语从句:a star that… and that…。第二个定语从句中it多余,that已经指代主语star,it同指代主语star,使这部分从句出现双主语。
D. Of应该为that
E. Of应该为that;that位于moon之后,引导的定语从句错误地修饰了moon。
