one day when they are having dinner我猜这个带when可能表示进行时所以用having,但下一句i am very busy
,when people go out to dinners这里也是when开头为什么没用ing的进行时呢,还有我知道有时候dinners与a dinner意思一样,如go out to dinners和shall we go out to a dinner tonight?所以我认为one day when they are having dinners对吗?
如go out to dinners和shall we go out to a dinner tonight？所以我认为one day when they are having dinners对吗？dinner加s对吗请求大家帮助！
