be doing
主要用于现在进行时态,有时可以用来表达将来时

哦,那我补充一下：
be to do sth.表示安排、计划、决定、命令或注定要发生的事.
一般用于被动语态,to be done
也可以用于主动语态.都是表示将来时态
比如：
Greater efforts to increase agricultural production must be made if food shortage is to be avoided.
为避免食物短缺,我们需要更加努力来提高农业生产.
The bridge is to be built next year.
大桥将在明年修建.
以下是主动语态的例句：

他就要死了.
To live is to work.
活着就要工作.
比较：
I am to be an engineer.
我就快要成为工程师了.（这个时间上快一点,而且比较有把握,比如已经考到证了.）
如果是：
I am going to be an engineer.
意思就变成了：
我将成为工程师.（这个只是主观愿望.没有多少把握）
2.to do是want to do
to be 是成为的意思
