VOA一分钟英语：快速辨析：all, everybody/everyone

单词 “all” 和 “everybody/everyone” 都可以用来指 “一群人当中的所有人”，但它们的用法可不一样！“All” 可以不加主语单独使用吗？
 
Hello, I’m Sam from BBC Learning English, and today we’re going to look at the difference between all and everybody or everyone, when talking about people.
In both cases, we’re talking about a group of people and the meaning is simple. They both mean ‘100% of the group’. But, how we use them in a sentence is slightly different.
Let’s look at these examples: I invited some friends to a party this weekend. They all came! Everybody came!
So, in the first example, we have the subject + all + the main verb. It’s not correct to say ‘all came’ without using the subject ‘they’ before all.
But, if you want to make the sentence shorter, you can use everybody or everyone as the subject of the sentence – so, everybody + main verb.
 
用法总结
1 用 “all” 来指代 “一群人当中的全部” 时，常用结构是 “主语 + all + 主要动词”。注意，这里的主语不能省略。
I invited some friends to a party this weekend. They all came!
We all went home after the class.
We all know this.
 
2 用 “everybody” 或者 “everyone” 来指代 “一群人当中的每个人” 时，常用结构是 “everybody/everyone + 主要动词”。“Everybody/everyone” 可以直接充当主语使用。
I invited some friends to a party this weekend. Everybody came!
Everybody went home after the class.
Everyone knows this.
