By 1999,astronomers had discovered 17 nearby stars that are orbited by planets about the size of Jupiter.
A. had discovered 17 nearby stars that are orbited by planets
B. had discovered 17 nearby stars with planets orbiting them that were
C. had discovered that there were 17 nearby stars that were orbited by planets
D. have discovered 17 nearby stars with planets orbiting them that are
E. have discovered that 17 nearby stars are orbited by planets
这里的B选项有没有跳跃修饰呀,到底是算修饰planets还是stars呢??求助求助!

A选项:Astronomers had discovered 17 nearby stars (that are orbited by planets) (about the size of Jupiter)
(about the size of Jupiter) 应该是修饰 stars 的,但是直接跟在planets后,导致修饰错误。

B选项:Astronomers had discovered 17 nearby stars with planets orbiting them that were (about the size of Jupiter)。that 后的从句修饰them, them 是stars.
然后 带回原句, astronomers had discovered 17 nearby stars with planets orbiting starts that were (about the size of Jupiter)
这样(about the size of Jupiter) 修饰的就是stars了, 然而句意就变了 句意成了:starts were about size of Jupiter.
我是这么理解的。然而我理解的是错的。。哈哈哈 正确答案是A

B 中them 也可以是 planest, 所以代词模糊,导致错误选项。

我读第一遍感觉A很清楚没毛病。
但是保险起见,看到一个By 1999, 说明是一个过去的动作,排除了DE, 剩下ABC。

C选项的that 改变了句意。排除。


B选项改变了原文的意思, 科学家们发现了(   伴随Jupiter size 一样大的planet 环绕)的17 nearby stars
原文意思是:科学家们发现了( 和Jupiter size一样大的)(被planet环绕的)17个nearby stars 。
那个Jupiter size 的位置发生了改变,原文的意思就不一样了。

总结: 句子改错题以不改变原意为首选。(我曾经好几题做错都是因为 选项修改了原文的修饰词语的位置,到时原文意思发生了改变)

直到1999年,太空人已經發現了17顆恆星,且這些恆星被和木星一樣大的星球所環繞著。

B.選項第一個問題就是讓你搞不清楚他想修飾哪一個名詞
第二個問題是them that ”were“ 用得是過去式,代表當時的大小和現在不同了。

题干去掉修饰Astronomers had discovered 17 nearby stars about the size of Jupiter. 这样说可以吗?

我怎么觉得 about the size of Jupiter 前省略了 that are,那它到底是修饰planet or stars? 我觉得是不是就近修饰的是planet。

先來看語意邏輯,不管about the size of Jupiter是修飾planets(自己認為是這個),還是修飾stars,在邏輯上都不會出現邏輯不合理之處。
所以個人認為不需要糾結修飾對象到底為何,因為這不是最後的判題點。
第二是建議藉由選項兩兩比對差異來判斷:

A. had discovered 17 nearby stars that are orbited by planets
B. had discovered 17 nearby stars with planets orbiting them that were

差異處有:
1. that are orbited  V.S. with planets orbiting
2. by planets V.S. them
3. that were
---------------------------
1. A選項的句意是強調有17顆恆星被與木星一樣大的星球所環繞,B選項是強調當時有星球正環繞著;
可以想想到底是有17顆恆星被很大的星球環繞有意義,還是有恆星被星球環繞有意義。

2. 清楚名詞與代名詞;若是在還沒看到them後面的修飾語時,
them 可以指代的對象有astronomers與stars,且兩個語意邏輯上沒有問題,
需要看到後面的修飾語才知道them真正想修飾的對象。

3. 陳述科學事實的現在簡單式 V.S. 過去式
個人認為題目是想陳述過去發現的科學事實(不會改變),而非敘述一件過去當下的發現(可能與現在有所不同了),這點可以比對AC選項看出差異。

By 1999,astronomers had discovered 17 nearby stars that are orbited by planets about the size of Jupiter.
A. had discovered 17 nearby stars that are orbited by planets
正确 by 1999 过去完成时的标志,在1999之前发生了“discovered”这个动作,that are orbited by planets修饰stars,about the size of Jupiter 介词短语修饰 planets
B. had discovered 17 nearby stars with planets orbiting them that were
“that were”是过去时,过去时意思是这件事发生在过去,然后就没有然后了,这里不正确,因为和Jupiter一样大小,这个大小没变化
C. had discovered that there were 17 nearby stars that were orbited by planets
同理B,“that were orbited”这是亘古不变不变的,应该用一般现在时
D. have discovered 17 nearby stars with planets orbiting them that are
时态不正确
E. have discovered that 17 nearby stars are orbited by planets
时态不正确
