“美国大学”（四六级听力）

angels

听力初级阶段打基础非常重要，运用台湾人赖世雄的逆向式学习法比较不错，用听力学英语。

重要的是弄清每一个没有听懂地方。





对照下面的原文。


Not all college teachers are professors. In fact, not even all professors are full professors. Many are assistant or associate or adjunct professors. This week in our Foreign Student Series, we sort out academic titles at American colleges and universities.

Professors usually need a doctorate degree. But sometimes a school may offer positions to people who have not yet received their doctorate. Such a person would be called an instructor until the degree has been completed. After that, the instructor could become an assistant professor. Assistant professors do not have tenure.

A person with tenure cannot be easily dismissed. Such appointments are permanent. Teachers and researchers who are hired with the understanding that they will seek tenure are said to be "on the tenure track." Assistant professor is the first job on this path.

Assistant professors generally have five to seven years to gain tenure. During this time, other faculty members study the person's work. If tenure is denied, then the assistant professor usually has a year to find another job.
