in addition to和in addition都是很常见很常用的短语,都有“除了、还有”的意思,但它们的用法是完全不同的。

In addition to整个词组相当于一个介词,所以to的后面要接宾语。例如:

In addition to native plants, this garden contains numerous trees and flowers from overseas.

除了当地的植物之外,这座花园还有无数来自海外的花草树木。

In addition相当于副词,通常放在从句的句首,后面接完整的句子。例如：

This garden has the best collection of nativeplants. In addition, it contains numerous trees and flowers from overseas.

这座花园有当地植物的最佳珍藏。另外,它还有无数来自海外的花草树木。
