为什么在“Look at this group of people playing beach velleyball"中,没有助动词be.
Thank you jioning CCYV's Around The World show.Today,we're in Australia.It's a beautiful,sunny day!There are many people here on vacation.Some are taking photos.Others are lying on the beach.Look at this group of people playing beach volleyball.They look cool!
动词的现在分词的构成是助动词be+动词ing.在“Some are taking photos”和“Others are lying on the beach”中,都有助动词be.为什么在“Look at this group of people playing beach velleyball"中,没有助动词be.
