这句话有语法错误吗 which 作什么成分 which 后面应该加 its Fluoride takes action in saliva,enhances the function which its prevention of sick tooth.前面是一个句子,后面用which引导一个从句,这样的结构对吗 翻译
不对.从句应是一个完整的句子（主谓宾这样的结构）
“氟化物与唾液作用,增强功能”是主句（句子主干意思）
而“阻止蛀牙的功能”是function的定语从句,这个定语从句中只有名词成分,不能构成完整的句子结构
另外,单数可数名词tooth需要冠词,或者用复数形式表示泛指
可以改为
Fluoride takes action in saliva,enhances the function which prevents sick teeth.
定语从句中,which代替function做主语,fuction prevents sick teeth才能构成完整句子结构
