英语疑问
However,there still remain less than ten percent of them who maintains主张/坚持 that it is the negative effects消极的影响 of internet that people and government pay attention to.
单词maintains加s因为它修饰的ten percent of them是不可数n ,我现在想问的是：there still remain 中的remain 为什么不加s?

Answer 1

there still remain 中remain 作系动词.
如果能理解there be句型中主语是be后面的名词那么remain不需要第三人称单数就很容易理解了.
句中主语应该是them,less than ten percent of 修饰them；
who 引导的定语从句也修饰them;
也就是说可以翻译成“仍然有……的人……”
