如果你要参加高考，在高考之前，请忽略以上内容，并记住中国人给它赋予的意义：

In hospital 表示住院

In the hospital 表示在医院办事等（除了住院之外的一切事务）

I have a aunt and she works in a hospital.

She works in a hospital.

She is working in the hospital.切记不要写成in hospital（住院）

下面6个句子He works in a hospital。对 他在一家医院工作。He is work in a hospital 错He work is in hospital 错He worked in the hospital 对 他以前在那一家医院工作。He works at a hospital. 可以。他在某一家 小 医院工作。hospital前面加a还是the ，取决于上下文。 如果这个医院 没有上下文提到过， 谈话的双方也都不知道这个医院， 仅仅是 泛泛而谈的 某一家医院， 可以用 a hospital. 上下文提到过的那一家医院 或者双方都知道的那一家医院， 就用 the hospital。宝贝勤学好问， 天天进步！
