以下是引用djsean在2006-7-17 20:10:00的发言:57. In astronomy the term "red shift" denotes the extent to which light from a distant galaxy has been shifted toward the red, or long-wave, end of the light spectrum by the rapid motion of the galaxy away from the Earth. (A) to which light from a distant galaxy has been shifted (B) to which light from a distant galaxy has shifted (C) that light from a distant galaxy has been shifted (D) of light from a distant galaxy shifting (E) of the shift of light from a distant galaxy 看过讨论57题的帖子后觉得结构问题解决了,但我还想提出两个对你们来说很浅的问题,第一这里为什么用完成时?第二 是说denotes the extent to which light from a distant galaxy has been shifted toward the red 在这里has been shifted toward the red不会是修饰galaxy吗?在这里不存在就近问题吗?请不吝赐教
一、用完成时是说明“红移”是一个结果,就是一个已经完成的动作,而不是一个进行中的状态,当然这个我也在知道正确答案后得出来的,做题的时候其实时态并没有造成什么障碍啊,其他错误比这个明显得多,当然lz这种打破沙锅问到底的精神是很值得赞赏的。 二、这个不可能是修饰galaxy的,用语修饰的无非有两种,一个是定语,也就是一个不成句的短语或单词,或前置,或后置,另外一个就是从句,那么请lz自己看一下,has been shifted toward the red符不符合这两个类型呢?显然不符合嘛,所以就不是修饰galaxy的咯 |
