exposure意为“接触；曝光、引起人注意”。get exposure是其转化成动宾结构的用法，同样具有“接触”和“引起人注意”之意。

比如大学生找工作，需要引起雇主的注意，专家会告诫学生：Attending conferences is an important way to get exposure. 另：How can I get exposure for my website without annoying people？在此句中，exposure也是引起人注意的意思。

下面我们来观察一下它表“接触”和“受到”时的用法。Involuntary Exposure to Tobacco Smoke被动吸烟；exposure to air pollution；childhood exposure to media violence儿童时期接触媒体暴力；exposure to higher education受到高等教育；students who have had little exposure to tertiary education很少受到高等教育的学生。

下面一段话是谈语言输入和输出的关系的，读一读对大家很有益，其中的exposure也是来源于其“接触”之意。

The more exposure or "data input" you have to the language, the easier it will be to produce or "output" the language. You can get exposure by watching movies and television, reading books and magazines, or talking to others in the language you are trying to learn.
