肯定一定的英语

他一定会来 He is sure to come. 那一定不是刘老师 That person can't be Teacher Liu. 一定要掌握英语 You must command English. 你一定喜欢她 You must have fallen in love with her. You must like her.这种表达方法容易引起歧义。可以理解成父母包办婚姻时逼婚的说法，也可以理解成推测的说法。 你一定没吃过这道菜。You couldn't have tasted this dish.有的时候还可以在后面加上点东西，变成You couldn't have tasted this dish，I bet. 昨天你一定没去学校 You definitely didn't go to school yesterday. 或 You couldn't have gone to school yesterday. 他一定还没来,别着急 Take it easy. He can't have been there. 英语里面确实还有一些词表示很肯定的意思，如bet，absolutely，definitely，exactly等

certainly, for certain, of course这组词(组)都有“确实地、一定地、当然地”的意思。其区别是：

1、certainly可位于句首或句末，表示强调，有时位于动词前，修饰全句，表示确有把握，深信不疑。例如：She certainly thought that this doctor was overestimating her case.她确实认为这医生夸大了她的病情。

2、of course通常用于表示自然的或不可避免的结果。例如：You could of course have criticized him, but,instead,you cried him down rudely.你批评他当然是可以的,可你却粗暴 地把他贬低。

3、for certain指确有把握，经常用于否定句中。例如：I can't say for certain when he will arrive.我说不准他什么时候到达。

扩展资料：

其中certainly用于修饰动词，表示同意所陈述的事或确信某事是真实的。certainly在句中的位置，如果有助动词(be，do，have等)，一般放于助动词之后。如果表示否定，一般放于助动词之前。也可位于句首或句末，表示强调。

certainly作“当然”解是非正式用语，多见于口语；作“必定”解是正式用语，口语和书面语均可使用。
