题型说明：按照所给汉语意思，写出相应词的恰当形式，完成句子。25.（2.0分）HT pushes the ___(边界)of the workplace which makes people more engaged in their work.

根据句意，“pushes the ___ of the workplace”需填入“边界”。单数“boundary”不符多方面界限之意，而“boundaries”更贴合“突破工作场所界限”的语境。完整句子为：“HT pushes the boundaries of the workplace which makes people more engaged in their work.” 答案：boundaries
