主语从句省略的补充

They will grow faster, although whether fast enough to justify their valuations remains to be seen.

请教老师whether后面省略的成分？

1. although 引导“让步从句”。

2. 在从句中，whether 引导主语从句。

3. 让步从句中，成分直观分析：

whether (it is) fast enough to justify their valuations （主语从句）remains（谓语动词） to be seen（不定式作状语）.

whether 从句中，省略了it is （形式主语 + 系动词，真正主语是to justify their valuations）

remain to be seen：有待于观察。比较文雅的说法是：“拭目以待”。

一个比较高级的句子写作，可以把这种 though(注意不是although)用成副词，放句尾：

They will grow faster; whether it is fast enough to justify their valuations remains to be seen, though.

再来一句比较喽的句子：

They will grow faster. However, whether it is fast enough to justify their valuations remains to be seen.

我这样一说，提问网友想必对该句子结构也可以了解了.
