Question

4． 
there be，cut．
There's a man cutting down the tree．．

Answer 1

分析 有个人正在砍树．

解答 答案：There's a man cutting down the tree．
图片上是一个男人a man在砍树，there be有，cut砍，故造句有个人正在砍树．表示正在发生的动作用现在进行时，故用there be的现在进行时there be sb doing sth，be动词遵循就近原则，a man单数，故is，砍树cut down the tree，cut的现在分词cutting，故答案是There's a man cutting down the tree．

点评 there be sb/sth doing sth表示某地有某人或某物正在做某事，如：There is a car collecting the rubbish over there．There are some people picking apples on the farm．
