[求助]一个简单白勇的语法

Biologists believe that they have found one of the substances that tell individual genes both when to become active and when to remain quiescent in the earliest phases of an embryo's development.

其中划线tell修饰的是哪个主语啊

我觉得是one of the substances

那不就应该用单数谓语动词吗

还有这一题请问大家26 In its most recent approach, the comet Crommelin passed the Earth at about the same distance and in about the same position, some 25 degrees above the horizon, that Halley's comet will pass the next time it appears.
(A) that Halley's comet will pass
(B) that Halley's comet is to be passing
(C) as Halley's comet
(D) as will Halley's comet
(E) as Halley's comet will do

D选项中will为什么要倒装，E为什么不对，do 不就是替换pass吗

繁盛空间

one of+复数名词，that就修饰那个复数名词

the (only) one of+复数名词，that就修饰the (only) one

繁盛空间

总之那个就是要倒装的，我也说不清楚为什么，就是感觉倒装读起来才顺口

正因为do是代表pass这个前文已经出现过的动词才要省略啊

wooyeon

one of 复数名词是用动词复数形式

然后the one of 复数名词 是用动词单数形式

情态动词加+do，动作与前文的一致的话 就省略do只留情态动词

所以这里不能有do

as后面如果动词一致的话是可以省略的,但是助动词和情态动词是要保留的...will是助动词所以要保留,而pass从句跟主句重复所以省略...
