1.为什么只能用have the right to do stj 而不能have a right to do sth 2 have a right to do sth ,have a right to sth 都可? have no right to do sth I have the right to do that. have the right to do something 这个句型是什么意思? you have the right to do everything怎么翻译中文 do people have a right to equal treatment in society? Do college students have a right to get married? Do closeted celebrities have a right to privacy? have an right （to） do have an right （over） sth?括号里的搭配对法? have a right to 能用must have to do sth 吗?
