VOA一分钟英语：Go on doing 和 go on to do 区别是什么？

动词短语 “go on” 可以分别与动名词（doing）和不定式（to do）搭配，组成 “go on doing” 和 “go on to do”。其中，哪个搭配用来表达 “继续做同一件事”？哪个用来表达 “进一步做另外的事”？
 
Hi, I'm Phil, and I'm going to tell you the difference between go on doing and go on to do something.
Now, the meaning of go on depends on whether it's followed by the gerund or the infinitive.
So, if we have go on doing, that's the gerund, it means 'to continue doing something'.
So, for example: I'd like to go on talking now.
Or: I really like this city. I'd like to go on living here for years!
Go on to do, that's the infinitive, means ‘to progress on to something’.
For example: I'd like to go on to study more languages.
Or: You could go on to have an even better job!
Just remember that if you go on doing something, you don't change, and if you go on to do something – you do change!
So, if you go on practising your English, you'll go on to be even better than you are now!
 
用法总结

I'd like to go on talking now.

If you go on practising your English, you'll go on to be even better than you are now!
 
2 “Go on to do” 指 “进一步做另外的事”， 即接下来要做的事与之前做的事相比有变化。
I'd like to go on to study more languages.
You could go on to have an even better job!
If you go on practising your English, you'll go on to be even better than you are now!
