帮忙看下这句话语法有什么错误!如何改正!
It is unlawful for an employer to discriminate when they are treated less fairly than other workers in a similar situation because of their race,color,descent or national or ethnic origin.

Answer 1

it 是形式主语,代表真正的主语是后面那一堆,(句子做主语,称为主语从句）
这里主句就是It is unlawful, 后面都是从句,既然是主语从句就需要用引导词作为开头,for 不能引导主语从句,而且后面也必须是句子,不是短语.
引导主语从句连词有that,whether,who,what,whatever等.
这里应该用that.
所以句子应该为：It is unlawful that an employer is discriminated when they are treated less fairly than other workers in a similar situation because of their race,color,descent or nationality or ethnic origin.
这样解释可以理解吗?
