RT，我看了一下翻译，这个地方是翻译成哈利就可以溜到厨房找吃的了，但是为什么原著是couldn't risk呢？还是说这是英文的什么语态呢？求解答，谢谢大家：
英文原文：
Harry lay in his dark cupboard much later, wishing he had a watch. He didn't know what time it was and he couldn't be sure the Dursleys were asleep yet. Until they were, he couldn't risk sneaking to the kitchen for some food.
苏农翻译：
哈利在黑洞洞的储物间里躺了好久，一直盼望能有一块手表，他不知道现在是几点，也不确定德思礼一家是不是睡了。等他们睡了，他就可以冒险偷偷溜到厨房去找点儿东西吃
