▲worse still 是惯用搭配，意思是“更糟的是”，在句中用作独立成分（不是普通意义的状语）。例句如：

I’m worried that his car has broken down, or worse still, that he’s had an accident. 我担心他的车坏了，或者，更糟的是，他出了意外。

Suppose Rose, or worse still , Peter had seen the photograph? 设想一下要是罗斯，或者更糟，要是彼得当时看到了照片会怎么样？

▲如果一定要换成一个句子，可以是 what is still worse is：

We’ve run out of petrol. Worse still, we can’t get any more until tomorrow. 

=We’ve run out of petrol. What is still worse is that we can’t get any more until tomorrow. 

汽油已经用完了。更糟糕的是，我们必须等到明天才能加油。
