here 和 there之前不加介词at的
直接说I'm here,she is there.
口语里,别人问你在哪里,随口答道I'm home是没问题的.但是受义务教育说I'm at home更舒服些.
我看到雅虎answer有人提问,我把这段发给你,转转引用的：
问题：I am at home ,i am in office ..are these sentences correct?
答案：yes..they are correct,i will make explanation why.
I am AT home.
The preposition indicates that the noun that follows them is treated as a point in relation to which another object is positioned.
some examples of using AT in:
*location
Tom is waiting for his sister at the bank.
Sue spent the whole afternoon at the fair.
*destination
We arrived at the house.
The waiter was at our table immediately.
*direction
The policeman leaped at the assailant.
The dog jumped at my face and really scared me.
要加at，at和home固定结构
如：he is at home而不是he is home ，如是he is home，就变成他是家了！
可以。i am home 和i am at home都是一样的。记得看电影，经常听到“anybody's home?”么？一样的。学口语不要过分纠结语法，你学是为了能让人家听懂，跟着模仿就行了。
原因如下：
at home 是一个固定词组
there 是一个不定代词
所以there的前面是不可以跟介词的。
