应该用复数，此类情况英语遵循语法一致的原则。如：
No goals were scored in the first half. 上半场未能进球。
No cars are allowed on the island. 岛上禁止驾驶汽车。
No books are to be taken out of the room. 书籍不得携出室外。
No tickets are needed for people over 65. 六十五岁以上的人无需购票。
No threats are going to shake me. 没有任何恫吓可以使我动摇。
用于there be句式也一样。如：
There are no jobs going right now. 目前没有职位空缺。
There were no doctors to treat the sick. 没有医生为病人医治。
There were no signs of forced entry into the house. 没有强行入室的痕迹。
There were no seats left so I had to stand up. 没有座位了，所以我只好站着。
不过，如果no后接单数名词（可数或不可数）作主语，谓语动词则用单数。如：
No news is good news. 没有消息是好消息。
No credit is given at this shop. 本店概不赊欠。
No student is to leave the room. 学生不得离开这个房间。
No reason was given for the change. 没有就这一变化说明原因。
