stay at home是固定用法吗?例如：可不可以用stay in china等 其他··· stay home /stay at home那句对?一般情况下,大家习惯用的是那一个?我见stay home 比较多,2.stay home ,stay 就是作不及物动词吧?be at home 这个固定就是来用at的。呵呵 he has to stay at home.提问是has he to stay at home吗? Lucy had to stay home yesterday because of th heavy rain.是个句子吗?stay home at home不是固定搭配吗？为什么这里不用at这个介词来连接呢？ home的用法The bad weather made us stay at home for the whole day.home不是副词吗?干嘛要加at,home也是形容词,但怎么判断home在这是形容词呢?是名词不好意思 是stay in home 还是stay at home. stay home和stay at home 有一样吗? she isn't stay at home有这样的用法吗,在哪里 We stay at home days中的days是什么用法? 到家是arrive home 还是arrive at home?待在家里是stay at home为何不是stay home?这个问题是一样的道理吗 stay后面是home能不能加at some people like to _______(逗留)at home.like to 后面stay要不要加ing?顺求like的固定用法. Stay at home stay-at-home stay at home 还是stay home? 是I stay at home to play games还是I stay at home to playing games they will stay at home tomorrow按划线部分提问stay at home是划线部分 在家用是stay at home还是 stay home抑或是stay in home 还是直接stay in,哪几个正确,有什么区别?不是说home前不可以加介词吗？···
