说话的时候，忘记加上就没什么咯。但是写作时候则一定加，因为他们每个词都是不同的用法和意义。像是辅助词，代词，动词.....那些之类的。在英文语法当中，这些词都是必须要根据在某些状况之下会用到的。come back是回来，go back是回去。其实英文单词是看你要说些什么来断定要加入那个单词会比较贴切或符合逻辑多一些咯。如果使用口语的话，你就算少加to,用go back here也是勉强ok的啦，但是光光使用back here的话也不是不行，但是就不正规咯，如果是在回答问题的情况下，而又只需要用这两个单词回答的话，用一下也没什么。但是正规的话还是不要的好。毕竟会养成习惯，到时候就在写作上也有语法写作的错误了。
