I don't think it is beautiful 这是一个否定句,也是宾语从句,为什么这个don't是否定“i

改成宾语从句:He is right .(I don't think) 宾语从句中为什么I don't think+宾语是根据从句,he doesn't think 就不行 She think it is beautiful but I don't think it is beautiful 除了i think 的宾语从句变否定句式,可将否定前移i don't.那you think ,he thinks.,是否 I don’t think it is { } coat I don't think it is possible. I,it,great,don't,is,think 连词成句 I know it that classmates don't know.是一个宾语从句吗? I think he is at home.改为否定句.为什么一定要改成I don't think he is at h 英语翻译don't 是否定no more 也是否定．i don't cry no more ,怎么翻译最通顺?是 no I don't think she is beautiful,but my sister i don't think she is beautiful,____ ____?
