区别一:两者均可表示“开始做某事”,其细微区别如下。
1. get to do往往暗示一个较长的过程,含有“渐渐开始”之意,此时get后接的不定式通常为to know, to like, to hate, to understand, to realize等表示心理感觉的动词。如:
I really wanted to get to know America. 我真想逐渐了解美国。
I shall get to like them in time. 经过一段时间我会变得喜欢他们的。
The best way to get to know the city is to visit it on foot. 要想了解这座城市,最好的方法是步行游览。
After a time you get to realize that these things don’t matter. 你过些时候就知道这些事无关紧要。
注:有时也可接表示心理感觉之外的其他动词。如:
His drinking is getting to be a problem. 他酗酒越来越成问题了。
He is getting to be a lovely kid. 他慢慢变成一个可爱的孩子了。
You’ll get to speak English more easily as time goes by. 时间一长,你的英语就会说得流利一些。
2. get doing主要用于非正式文体中,通常表示某种特定动作的开始,尤其用于get moving, get going, get thinking等搭配中。如:
We’d better get moving—it’s late. 我们还是走吧——时间不早了。
They soon got talking together. 他们不久就开始谈了起来。
He got to thinking that she perhaps wouldn’t come after all. 他已意识到也许她根本不来了。
区别二:get to do可以表示有机会做某事或被许可做某事,但get doing没有这样的用法。如:
He never got to go to college. 他从无机会上大学
We didn’t get to see her—she was too busy. 我们没有见到她——她太忙了。
When do I get to see your new baby? 我什么时候能去看看你那刚出生的孩子呀?
Did you get to visit the Louvre when you were in Paris? 你在巴黎的时候有机会去参观卢浮宫吗?
区别三:get to do 还可以表示努力或设法做成某事,但 get doing 没有这样的用法。如:
At last he got to knock it down. 最后他设法把它敲了下来。
Did you get to buy the tickets? 你设法买到票了吗?
How did you get to be captain? 你是怎样当上船长的?
