关于be busy doing
the money will be used to keep a space vehicle on the moon busy ( ) back to the earth photographs and other information about the surface of the moon.
A to send B being sent C to be sent D sending
这道题结构是什么啊,我选对的,以为是be busy doing的结构
回来看看觉得不像嘛,没有be的啊
有没有人明白!

这道题出的有点难答案是D
首先有个句型keep sb/sth doing 让某人/物（一直）忙
在有be busy doing ,只是这个短语做谓语时才会用上be
而题中busy sending back.moon 是做补语的,补充说明忙着干吗,这时就不能在加be了
翻译：这些钱将会被用来运行月球上的飞船,让它不断向地球发回月球表面的照片和其他信息.

be busy doing造句 be+busy+doing=be+( )+( be busy doing 和 be busy in doing 的区别? be busy in doing sth be busy doing sth 例句 be busy doing等于什么 be busy doing中doing什么成分 be busy with sth 与be busy doing sth 为什么是be busy doing而不是be busy to do be busy doing sth和be busy with sth be busy with sth.be busy doing sth. "be busy to do " 还是 " be busy doing"
