问辨析同义词不可以吗？我是在外企工作的，和外国人一起做项目的，口语和词汇量方面足够了。你怎么知道在这里学不到什么东西？

我看你问的问题基本都是辨析同义词的，你的很多问题实际上都被问过几百遍了， 你不妨google 搜索一下，很多网页都有很好的解答，不然这里基本没有人会给你所要的答案，都是草草地回答你的问题，你也学不到啥还浪费自己的时间。

There is a slight difference in the meaning of abstain and refrain. Although, many times they could be used interchangeably. Abstain - is to avoid something or choose not to be part of something you like Refrain - is to stop oneself from doing something (could be anything) Restrain - is to stop others from doing something.
