例如：The lecturer gave an interesting talk on modern English literature.（这位讲师就现代英国文学作了一个有趣的演讲。
）
二、lectureship（名词）
1. 解析。
- 由“lecture”加上 -ship后缀构成。
-ship这个后缀可以表示“职位；资格；身份”等意义。
“lectureship”表示“讲师的职位（或资格）”。
例如：He applied for the lectureship in the university.（他申请了这所大学的讲师职位。

三、lecturette（名词）
1. 解析。
- 这是在“lecture”的基础上加上 -ette后缀。
-ette后缀有“小”的意思，在这里“lecturette”表示“简短的演讲；小型讲座”。
例如：The conference included several lecturettes on different topics.（会议包括几个关于不同主题的小型讲座。
）。

一、不定冠词的主要用法1. a和an 是泛指限定词，用于单数可数名词前，泛指人或物。
在首次提及的人或物前，a或an 一般表示数量“一”。
a用于以辅音开头的名词前：a piece，a language，a university。

e.g. I) It has been a rewarding lecture.II) I work for Sony Electric, an electronics company. 我在一家电子公司――索尼电器工作。
2. a和an也可用在可数名词前表示一类人或物。
e.g. I) A friend is someone who chooses and is chosen.II) Lend me a novel, will you?3. a和an用在某些物质名词前表示一阵、一份、一类、一场、一种等。
