大全146为什么就不选C 呢？

大全146

Astronomers studying the newly discovered star say that it provides clues about our galaxy’s origin, that it may supply data about how fast our galaxy is expanding, and moreover it is perhaps the most distant star in the entire Milky Way.

(A) about how fast our galaxy is expanding, and moreover it is perhaps

(B) regarding the speed our galaxy expands at; moreover, they think it may be

(C) about how fast our galaxy expands and perhaps be

(D) on the galaxy’s expansion rate and perhaps（E）

(E) about how fast our galaxy is expanding, and that it is perhaps

这道题目虽然比较简单，但是做的时候还是选择错了，选了C。

请NN们帮助解释一下，为什么C就不对？是将省略成分还原不对吗？

当时看到题目就想到了动词省略的情况。

其他选项没有怎么仔细看，就选择了C。

请教NN，SC排除选择的优先级别问题。

看到有人说 that ... that 的级别很高的。但是我为什么还是当时脑子热选择了C？

省略还原下就知道不对了把，C后面是it perhaps be, be应该为is。

就算你把最后一句话看成

may supply and be 的并列的话，也重复了modal auxiliary咯

你看看

it may supply data about how fast our galaxy expands and （may） perhaps be the most distant star in the entire Milky Way.

may 和perhaps重复了哦

正确答案的形式是Astronomers say that..., that..., and that...这个形式当然没问题。

B的形式是Astronomers say that..., that...; moreover, ...

请教B为什么不对？我实在找不到一个满意的理由把B排除

是因为最后一个(也就是第二个)that前面必须要用and吗？
除此之外，我觉得B的语法完全正确啊
regarding = with regard to加名词，用在这里好像应该没有问题（虽说上个定从里用的about, 但regarding没错吧）
the speed our galaxy expands at = the speed at which our galaxy expands 应该也对
上个定从的provides clue about origin和supply data regarding speed都是动+名+介+名的结构，很对称，优于第一个用动+名+介+名，第二个用动+名+介+从句

垦请指点，多谢！

B的问题有以下：
1。因为前面两个that..没有用and连接。如果是they believe that ..., and that ....;moreove ... 可能还比较对they believe that..., that...;moreover肯定不对吧。
2。另外，they think that it may be ... 中宾语从句的that不能省。
3。再有多一点，may be的结构中给原文增加了一个情态动词（取代了perhaps)，要尽量避免改动原文的情态动词。

从原文意思上来说，没有把最后一个从句特殊强调的意思，应该是3个从句并列。所以只看并列结构就选出E.

2。另外，they think that it may be ... 中宾语从句的that不能省。

谢谢！我忘了这茬儿拉。这条否定掉B足矣
