Question

tell the boys （）there（　） make so much noise。 A played ：not to B playing ：not to C plays ：

Answer 1

选B
Tell the boys playing there not to make so much noise.
句子中省略了who are，完整句子为Tell the boys (who are) playing there not to make so much noise. playing there表示伴随状态，指代孩子，解释为正在玩耍的男孩们。
tell sb. to do sth. 和 tell sb. not to do sth. 为固定搭配，意为告诉某人做某事；告诉某人不要做某事。
句子大意：告诉在那儿玩的男孩们不要吵闹。
