there be+名詞+現在分詞

現在分詞表示主動關系，同時表示動作正在進行：

There was a man standing in front of me. 我前面站著一個男人。

There were some children swimming in the river. 有些小孩在河里游泳。

There were a group of young people working in the fields. 有一群青年在地里勞動。

有時現在分詞可表示一種狀態：

There’s a piano standing against the wall. 靠墻有一架鋼琴。

There’re a lot of difficulties facing us. 我們面前有很多困難。

There is a door leading to the garden. 有一座門通往花園。

有個別現在分詞用于該結構時可以表示將來(正如它們可用進行時表示將來一樣)：

There are ten people coming to dinner. 有10個人來吃晚飯。
