Step 3 问题探究
( )1.There must be a worker ________ the rubbish in the street.The street is very clean.
A．collect B．to collect C．collects D．collecting
答案选择D，本句是there be和情态动词连用表示对某地有某物的推测。there must be的意思是“一定有”所以答案选D。
“There＋情态动词＋be＋sb. doing sth.”表示对“某地有某人正在做某事”的一种推测。
( )2.We have fun ________ with your sister. A．talk B．talks C．to talk D．talking
答案选择D，动词短语have fun＋(in) doing表示某人在做某事方面有乐趣的意思，省略了介词in，在介词的后面用动名词形式作宾语。
