三 语法讲解
Her father and her defense attorney say they will keep working for her freedom.
keep doing sth. 和keep on doing sth.
keep doing sth. 和keep on doing sth. 意义及用法相同，但后者更强调决心和重要性。如：
He kept coughing all morning．
他整个上午不停地咳嗽。
He kept on phoning me, but I really didn’t want to talk to him．
他不断给我打电话，但我实在不想和他说话。
keep或keep on后跟表示动作的-ing形式，不可接动词不定式或表示静止状态的-ing形式，不能说He kept on to talk. 也不能说They kept on sitting.
