整理到这一题发现是新题，我是想找一下A 选项的having been 的错误，觉得用wordy 来笼统解释说服不了我啊，后来在外网搜到了这一题的分析，我把我觉得有用的贴上来哈！

首先整理回答我自己的问题 A的having been的错误，帖子是这么说的：
Having Been creates a timeline in the past which refers that Action A happens before Action B in the past.
Here it means -
Naming the mythological Nymph------------Discovery of the asteroid named IDA.

所以这个命名的action是早于主语中的发现这个action，这样一说，我觉得我接受了。

再是关于这种类型的题目，帖子总结到是“三明治”句子，给了一些怎么处理这种句子的建议：
The first thought in such sandwiched sentences is to decide the chronology of the events. The discovery is the first event and hence has to be described first with a modifier status. Then is the naming phenomenon, so push this incidental info to the next in another modifier. The third most important point is what it is doing and where it is doing at the moment. Give this most important factor a verb status. 

其实我个人感觉他这样说有一点点马后炮，哈哈，原因是他的规则是完全往这个正确句子的chronology上靠的。但是分析一下B 这个正确的选项，感觉他说的还是挺有道理的：
Discovered in 1884, the asteroid Ida, named for a mythological nymph who cared for the infant Jupiter, is in the middle of the belt of asteroids that orbit the Sun between Mars and Jupiter.

可以看出来B选项是按照逻辑顺序有过去到现在来构句的： 首先是1884年发现，再被命名，再是表述Ida 星是处在太阳和火星、木星绕着的星云带中间。
这样两个modifiers 按照时间顺序在前，句子的core 在后。

C,D,E 选项错误帖子分析如下： 把各个句子拆分指出哪里有问题：
(C) In the middle of the belt of asteroids that orbit the Sun between Mars and Jupiter, the asteroid Ida, discovered in 1884 and named for a mythological nymph who cared for the infant Jupiter.
Seems like a jumbled sentence - Wordy and Awkward.

(D) The asteroid Ida, named for a mythological nymph who cared for the infant Jupiter and discovered in 1884, is in the middle of the belt of asteroids to orbit the Sun between Mars and Jupiter. 

Incorrect. ( highlighted portions) 

(E) Ida, an asteroid discovered in 1884 and which was named for a mythological nymph who cared for the infant Jupiter, is in the middle of the belt of asteroids to orbit the Sun between Mars and Jupiter
Incorrect ( highlighted portions)

"Having Been creates a timeline in the past which refers that Action A happens before Action B in the past."

这句话我不是太明白耶，是说如果现在完成时和一般过去时在同一个句子里时，现在完成时的那件事一定是先发生的吗？
可是我记得og里有一题的正确答案是 The Bigbang Theory holds that the universe began in an explosive instant xx years ago and has been expanding ever since. 这句话就是先began，后has been expanding的，那题目中A选项不能理解成先discovered后has been named吗？

等等，我自己搞懂了
因为这里having been作伴随状语，而伴随状语中的动作或状态一定是早于主句动作或与主句动作同时发生的，所以A选项的意思就变成了，当这个星星被发现的时候已经被命名了，这在逻辑上是错的
和是不是现在完成时没关系哈，大家别被我带坑里去了

小行星-

想问一问，C选项中the asteroid Ida,discovered in 1884 and named for as mythological nymph who cared for the infant Jupiter..怎么判定里面的discovered不是谓语动词 而是done结构的非谓语？？求解释。。感觉对非谓语这里不是很明白，，都是过去式如何区分？

因为这个行星是被发现的，所以discover若作为谓语动词，应该加上be动词，表被动，也就是was discovered. 但是C选项里没有be动词，明显是修饰语。因此这个句子错在没有main verb.

好的，明白了！谢谢你！

关于B选项有个问题~
Helr大神在gmatla里提过主从句的图形背景原则，就是说“从句（或者分词短语等非谓语动词引导的短语）需要在时间上延续的更长，主句需要在时间上延续的更短”。
应用到这里的B选项，明明discovered和named延续时间短，be in the middle of the belt of asteroids延续时间长，却反而是延续时间长的作主句呢？
跪求NN解答啊  o(╥﹏╥)o
