Using a criterion based on an object's color, astronomers recently identified 23 galaxies so distant from Earth that their light has taken 85 percent of the age of the universe to reach us.
astronomers recently identified 23 galaxies so distant from Earth that their light has taken
astronomers recently identified 23 galaxies that were so distant from Earth for their light to take
astronomers recently identified 23 galaxies to be so distant from Earth such that their light takes
23 galaxies were recently identified by astronomers to be so distant from Earth for their light to take
23 galaxies were recently identified by astronomers as so distant from Earth their light has taken
题目分析:
略。
选项分析:
选项A:Correct. 本选项在语法和逻辑上均是正确的。
选项B:so身后用了不定式的复合结构for somebody to do something,应将其改为结果状语从句,即,so that their light has taken 85 percent of the age of the universe to reach us。这点考查了不定式和从句的区别。用之于本题,在主句“天文学家识别出23个星系”这个动作发生时,不能说“它们的光需要花费85%宇宙的年龄来到达地球”是将要开始的(或者将要结束)。不论是否“识别”,这些星系的光需要花费的时间均不会发生改变。因此,应该用从句。
选项C:第一,不定式短语to be so distant from Earth应去掉to be这个不定式。这点考查了不定式和从句的区别。用之于本题,“识别”这个动作发生时,“23个星系距离地球很远”是一个固有属性,不会发生状态的变化。第二,可以用so that表示“所以”,也可以用such that,但是不能用so…such that,这会引起赘余。
选项D:句首的现在分词短语using a criterion based on an object's color是伴随状语,其主语必须同其修饰的句子的主语相同,即,23 galaxies。逻辑上,用一些标准的只能是“天文学家”而不能是“23个星系”。另外,to be so distant错误同选项(C);for somebody to do something错误同选项(B)。
选项E:using a criterion based on an object's color的逻辑主语错误同选项(D)。
一、时态。天体的远近是客观存在的,因此用现在时,所以that were 错了
二、so...that 结构。变成 so...for 明显错误
