Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.
Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting
Like any star of similar mass, once the hydrogen in the Sun's core is exhausted, then it expands into a red giant and eventually ejects
As in the case of any star of similar mass, once the hydrogen in the Sun's core is exhausted, it will expand into a red giant, and eventually ejecting
As any star of similar mass would, once the hydrogen in the Sun's core is exhausted it will expand into a red giant and will eventually eject
As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject
As (would ) be the case with
B，比较对象不一致
C，as后需要接句子
D，it指代不明，这里合适的指代对象是hydrogen，但不合理
E correct
2、如果不确定as后面的内容，可以先往后看，发现it，找指代对象，CD里面的it指代的是 hydrogen，明显指代不对，应该是sun膨胀
C: and eventually ejecting ...结构不对。
D: as后面接句子，但是any star of similar mass would，句子结构不完整，少了个be。it指代的是hydrogen。
B: it指代的是hydrogen。
Like "As in the case of..." and "As is the case with...", this construction can only describe things that have actually happened.
B: star 与hydrogen 比较对象不对等；it 错误地指代hydrogen，应该指代Sun，但在该选项中Sun
是以所有格形式出现的，it 无法指向所有格形式的Sun；被动语态的表达不如主动语态更清楚。
E：As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core,it （will expand） into a red giant and（eventually eject） its outer envelope ……
E 里如果 as 是引导状语从句，once 也是连词引导状语从句，这两个状语从句之间可以就这么放着吗？记得之前看过视频说 两个状语从句之间也需要有并列连词，不能直接放着？
1） 比较的常用结构as be the case (with)…，是as the case be 的倒装形式，其常见的错误
用法包括：as it be；than be the case；as in/with the case of；
2） like/unlike，前后比较对象对等（like/unlike 开头的强调对比的句子，主语要以进行比较
的对等的名词开头）。常见的错误用法有：比较对象不对等；as+noun；like+句子。
句子结构-连词，在表达比较的意思“像…”时，like 用作介词，后面只能跟名词或代词，不能连接句子，
这种情况下如果要用句子表达对比，须用as。
指代一致，（指示）代词it 不能指向所有格形式上的名词。
平行-错误平行，看到and 要特别注意句中是否有正确的平行对象，句中是否应该出现平行对称结构，
该平行结构是否符合原句所要表达的意思。
词结构ejecting在句尾作状语，表示伴随结果，所表达的同时发生的意思不如用and连接的并列谓语更
准确，因为后者能准确表达先后发生的意思（由eventually可知）。
(B) star 与hydrogen 比较对象不对等；it 错误地指代hydrogen，应该指代Sun，但在该选项中Sun
是以所有格形式出现的，it 无法指向所有格形式的Sun；被动语态的表达不如主动语态更清楚。
(C) as in the case…的表达方式不正确；it错误地指代hydrogen，原因与选项B相同；and ejecting没
有平行对象。
(D) it错误地指代hydrogen，原因与选项B相同；用as连接句子表示比较也正确，但不应该用过去时态
would，应该用将来时will；被动语态的表达不如主动语态更清楚。
(E) 正确，as would be the case with…是比较结构的一种，表达比较对象的情况相同。
A, Like引导对比只能跟名词。A是一整句，A 排除
B, Comparing any star with the hydrogen -- wrong
C, comparing the case of a star with the hydrogen; the unparallel " ejecting' phrase after 'and'
D, would作为helping verb，后面却没有跟verb，错； star对比hydrogen；读者无法通过句意知道it 代sun 还是 hydrogen。
E: As would be 就像XX一样，as would be the case with...是比较结构的一种，表达比较对象的情况相同。
“in the case”是所有介词短语中最灵活的一种。 实际上，“ the case of”的全部存在是基于这样一个事实，即这些单词可以在句子中指代几乎所有内容
As in the case of any star of similar mass, it will expand into a red giant once the hydrogen in the Sun's core is exhausted, 这里是将any star of similar mass和sun比较，in the case of any star里any star是主语，而主句里sun是地点修饰语，这样会导致被比较部分无法参照主句的格式做补全，说明该省略错误
结论：两个被比较部分在句子里充当相同的成分才可以做省略
B, Comparing any star with the hydrogen -- wrong
C, comparing the case of a star with the hydrogen; the unparallel " ejecting' phrase after 'and'
D, would作为helping verb，后面却没有跟verb，错； star对比hydrogen；读者无法通过句意知道it 代sun 还是 hydrogen。
as比较加倒装句，as is the case with noun, ...
Once后说的是一个动作，所以平行的话前面得是动作，排除a
比如 With......As with.....才可以用As with.
否则只可以用 As is the case with....... As is the case with就没有什么限制了。
