求助nn~~
By 1999, astronomers had discovered17 nearby stars that are orbited by planets about the size of Jupiter
原文就是正确答案。
没搞明白about the size of Jupiter修饰的是谁？stars还是planets？
谢谢~~~

补充：A.had discovered 17 nearby stars that are orbited by planets
如果把E时态改对了:
E.had discovered that 17 nearby stars are orbited by planets
这样E对不对？

A选项 had discovered 17 nearby stars (that...)
E选项 had discovered (that....)

显然是修饰planets的，这个句子的结构分析师这样的：

(By 1999), astronomers had discovered 17 nearby stars [that are orbited by planets (about the size of Jupiter)].

前面的by 1999是时间状语，修饰主句。句子的主句是astronomers had discovered 17 nearby stars，紧接着后面跟了一个that从句，修饰前面的stars，这个that从句包含了about这样一个介词短语，是对前面的planets进行的修饰。

以下是每个选项错的原因：
B. Them多余，没有必要加，其次them指代也不明，然后them放在这是的that 引导从句修饰的是them，语义也不对。其次时态也不对，不能用were。
C. That there were 多余，没有必要加。其次时态也错了，它是一直在围绕它转，因此第二were错误，客观事实，用用一般现在时。
D. By + 过去时间要用过去完成时
E. By + 过去时间要求用过去完成时

因此正确选项就是A啦
