红警大战2腾讯版:I really don't know how to read this word.

你试着比较一下这两个就知道了

I really don't know who she is.我真的不认识她.
I don't really know who she is.她啊...我就知道那么一点.也不是特了解.

可以看出,前者是彻底否定的.就比如在我的世界没有个人一样的感觉.
而后者是指并非真正认识那人,比如别人问你她的年龄时,你就不知道了,你知道的仅仅是存在她这个人或者稍微比这多一点点.
揣摩一下,不难懂滴~~
希望可以帮上你.

后缀-ly形式的副词,表示比较抽象的概念,有引申义,并有一定感情色彩,用此类副词,如修饰动词和分词,放在它们前面。

不是谓语。修饰do not，加强语气。

副词及其基本用法
副词主要用来修饰动词,形容词,副词或其他结构.
一,副词的位置.1) 在动词之前.2) 在be动词,助动词之后. 3) 多个助动词时,副词一般放在第一个助动词后.注意:
a. 大多数方式副词位于句尾,但宾语过长,副词可以提前,以使句子平衡. We could see very clearly a strange light ahead of us.
b. 方式副词well,badly糟,坏,hard等只放在句尾.
He speaks English well.
二,副词的排列顺序:
1) 时间,地点副词,小单位的在前,大单位在后.
2) 方式副词,短的在前,长的在后,并用and或but等连词连接.
Please write slowly and carefully.
3) 多个不同副词排列:程度+地点+方式+时间副词.
注意:副词very 可以修饰形容词,但不能修饰动词.
改错:(错) I very like English.(对) I like English very much.
注意:副词enough要放在形容词的后面,形容词enough放在名词前后都可.
I don't know him well enough.
There is enough food for everyone to eat.
There is food enough for everyone to eat.

详细的说，你就看上面的；简单来说，就是只有副词才可以修饰动词，而really是副词。仅此而已。

是副词,修饰句中的动词"know".根据不同的句型有的副词用在动词前，有时则用在动词后．
