still 有时可以修饰带有“递进意义”的代词、形容词，副词比较级（如：still another；still better, still further）等。可以看作“强调副词”。例如：

Why does he want to invest in still another business?

他为什么还想投资另一项业务？

He had made still another characteristic mistake. 

他自己又犯了一次习惯性的错误。

I wish you still further success! 

预祝你取得更大的成功！

To examine your skills and abilities still further. 

仍然更进一步考验你的技能和能力。
