They are climb trees这句话哪里不对
They are climb trees这句话哪里不对

They are climb trees这句话哪里不对
如果要用一般现在时就直接They climb threes.不用are.但如果想说他们正在爬树就要用现在进行时,They are climbing trees.

They are climbing trees

are是be动词,climb是动词,两个动词重复,只有在现在进行时才会用be+doing

be+动词ing表示现在正在做,若有be动词,则后面的动词需用现在分词(ing),即
They are climbing trees. (他们正在爬树)
