将来进行时有be going to be doing这个表达形式吗

将来时有BE DOING么?be going to do和BE DOING是算在现在进行时表将来? be doing (现在进行时表将来）和be going to do有什么区别 be going to ,will ,will be doing 三种将来时有什么共同点,又有什么不同点? will,be going to do,be doing表将来 be going to 是现在进行时表将来吗 be going to do 和will do和 be doing都能表将来吗? be going to表将来、be doing表将来和will/shall+do三者间的区别 be going to do,will be,be doing三种用来表示未来时有什么差别? be going to doing有这个用法吗 怎么区别一般现在时表将来,现在进行时表将来和be going to 表将来 将来时态的区别be going to;will do;be doing;be to do;be about to do be doing表将来与be going to区别?不要抄的?
