问题描述：
The most frightening thing of all was that not a sound could be heard.There was no doubt that we were unwelcome visitors.no 和not 的用法
答
1.no 用作形容词,置于可数名词单数前面时,相当于 not a;
2.放在可数名词复数前面或不可数名词前时,相当于 not any,意为“没有的,全无的”“远非的,完全不是的”
例如:Kate is no teacher.(=Kate is not a teacher.) 凯特根本不是教师?那例句可以改成no sound,和 not a doubt 喽？语法上是not any doubt，但是还得考虑用语习惯啊，有的可以改，有的改了拗口
