还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
C：插入语拿去，circling紧跟planets
因为中间有个插入语 ( , most of them at least as large as Jupiter, )，如果去掉插入语，circling就是紧跟在planets后面修饰planets, 就可以写成astronomers have detected more than 80 massive planets circling other stars
所以 circling other stars就成修饰宾语planets了。
可以看成是省略了being的独立主格，做伴随状语。那么因此circling的主语就是most of them，而不是Jupiter
C.circling在这里不存在伴随的歧义，伴随一般是指伴随动作，因为本句唯一的句子是天文学家detected...，若认为伴随是不可的，逻辑主语就成了astronomers，逻辑错误；此处circling作定语修饰Jupiter.
另外可用固定搭配排除，as large as or larger than = at least as large as
which不可能是Jupiter的定语从句，因为谓语动词是复数形式，如果是定语从句则一定是跳跃修饰。另外as large or larger than的说法一定是不对的登录 或 注册 后可以参加讨论
用most of them做同位语也是可以的，和用most of which做定语从句在这道题目中是一样的。登录 或 注册 后可以参加讨论
