“It was not one object but several.” The captain said, “We saw one large and six smaller objects. I sent out a radio to report about them and I received the answer that the other planes were coming out to meet us. Before the planes arrived, the smaller objects entered the big object. The big object then became smaller and moved away fast.”

They were waiting for you yesterday.

疑问形式：Was/Were+主语+V-ing。

基本用法：
