She began work immediately这句话有没有错啊?是不是应该是begin to work?

应改为 She began to work immediately.begin to do 强调某一次的行为,而begin doing 强调长期的动作.如 The baby begins to cry when it feels hungry.I beganplaying the piano when I was five years old.
begin 既是及物动词又是不及物动词用法如下：
及物动词 vt.
1.开始,着手;动手[+v-ing][+to-v]
When did you begin learning English?
你何时开始学英语的?
He is about to begin his term as President.
他即将开始他的总统任期.
After breakfast it began to snow.
早饭后开始下起雪来.
2.创建;使开始
They began the club about four years ago.
他们大约在四年前创办该俱乐部的.
不及物动词 vi.
1.开始;开始进行
The concert began at 8 p.m.
音乐会晚上八时开始.
2.始于;源于
The campaign began last year.
work 在句中是动词的词性.
