有人说 in addition 是介词短语,而 in addition to 是短语介词。请问这是如何区分的?
龙老师:
没错,in addition 是介词短语,而in addition to 是短语介词。
▲什么叫介词短语?简单地说,介词带上自己的宾语就叫介词短语,比如你说的in addition (in 是介词,addition 是其宾语)。但这个 in addition 本身又是一个固定搭配,意思是“此外,另外,还有”。如:
In addition, they do not match very much. 除此之外,他们两人并不十分般配。
We met some friends and other people in addition. 我们遇见几位朋友,还遇见其他一些人
▲什么叫短语介词?简单地说,就是它本身既是一个短语,同时又起介词的作用,比如你说的 in addition to,它本身是一个短语,但它同时又是一介词,意思是“除……之外”。如:
We play football in addition to basketball. 除了篮球外,我们还踢足球。
In addition to English, he has to study a second foreign language. 除英语外,他还得学第二外语。
顺便说一句,这里的 to为介词,所以后接动词作宾语时要用动名词。如:
In addition to giving a general introduction to computers, the course also provides practical experience. 课程除了大致介绍电脑知识外,还提供实际操作的机会。
另外,当主语后跟有in addition to引出的介词短语时,谓语动词仍与其前的主语保持一致。如:
The teacher, in addition to his students, was interested in the book. 老师和他的学生都对这本书感兴趣。
