1、此句确实有了问题，应该改为：

还原后是：
The attack was so 【sudden】that we had no time to escape。
替换后是：
This was so sudden an attack that we had no time to escape。
=This was such a sudden attack that we had no time to escape。
由以上可知，其中的suddenly一定用错了，因为他是修饰后面的名词attack，并作其定语。
2、这个句子是部分倒装：
so+adv/such+adj 置于句首构成的部分倒装。
The attack was so 【sudden】that we had no time to escape。
由上句可见，是将句子的表语提前而构成的部分倒装。收起
